Chief Justice BENDER
delivered the Opinion of the Court.
I. Introduction
T1 In this appeal, we review the order of the Jefferson County District Court upholding the county court's determination that the six-year statute of limitations contained in section 18-80-108.5(1)(a), C.R.S. (2011), did not bar respondent Account Brokers of Lar-imer County, Inc.'s claim against petitioner Daniel Shane Hassler. Account Brokers v. Hassler, No. 2009CV444 (Jefferson Cnty. Dist. Court May 19, 2009).
T2 Hassler financed the purchase of a vehicle by entering into a security agreement with Account Brokers' predecessor-in-interest, Norlarco Credit Union, in which the vehicle served as collateral. The security agreement provided that the balance of the loan plus the attendant interest would be repaid in monthly installments. When Has-sler later defaulted on his loan, Norlarco first repossessed the vehicle and then later sold it at auction. Norlareo applied the proceeds of the auction to the balance of the loan. The proceeds, however, were insufficient to cover the balance, and thus Hassler remained indebted for the deficiency. Norlareo eventu[549]*549ally transferred this debt to Account Brokers, who initiated the present suit. Account Brokers sued Hassler to recover the deficiency less than six years after the vehicle was sold at auction but more than six years after Hassler defaulted on the loan and the vehicle was repossessed. Ruling in favor of Account Brokers, both the county court and district court on appeal determined that the statute of limitations did not bar Account Brokers' claim because the amount of the deficiency was not "liquidated or determinable" until Norlareo sold the vehicle at auction.
I3 We reverse. The relevant legal inquiry under the statute of limitations is the date that the debt was made liquidated or determinable but rather the date that the debt accrued, which section 13-80-108, C.R.S. (2011), entitled "When a cause of action accrues," defines as the date that the debt became due. § 18-80-108(4). We hold that under Colorado law and the express terms of the parties' security agreement, the present debt became due when it was accelerated following Norlarco's repossession of the vehicle and demand for full payment on the debt, which occurred more than six years before the initiation of the present suit. Accordingly, the action is barred by the statute of limitations.
T4 Construing sections 13-80-108.5(1)(a) and 13-80-108(4), we conclude that the six-year statute of limitations for an action based upon the rights set forth in a security agreement begins to run on the date that the cause of action accrues, which is the date that the debt first becomes due. For a security agreement that is to be repaid in installments, the debt for each installment becomes due on the date that each installment is missed. Once an installment security agreement is validly accelerated, however, the entirety of the remaining balance becomes due and therefore the cause of action to collect the entire debt accrues.1
T5 In this case, Norlarco invoked the seeu-rity agreement's optional acceleration clause by repossessing Hassler's vehicle on October 30, 2001, and sending him a letter shortly thereafter demanding that he repay the entirety of his debt. Because Account Brokers, Norlareo's successor-in-interest, filed its claim to collect the remainder of the debt on May 7, 2008, which was more than six years later, we hold that the present claim is barred by the statute of limitations. Thus, we remand the case to the district court to be returned to the county court for proceedings consistent with this opinion.
II. Facts and Procedural History
T6 In October 2000, Hassler financed the purchase of a vehicle for $28,565.25 through Norlarco Credit Union. A security agreement, entitled "Open-End Voucher and Security Agreement," set forth the terms of the parties' agreement. The security agreement obligated Hassler to pay monthly installments of $5283.00 beginning on November 19, 2000, and gave Norlareo a security interest in the vehicle Hassler purchased.
T7 The security agreement defined default as "break[ing] any promise you make under this agreement." Paragraph 10 of the security agreement, entitled "What Happens if You Are in Default," specified the consequences of default to borrowers in different states. For Colorado borrowers, the security agreement authorized Norlarco to accelerate the loan and to require immediate payment of the outstanding balance at its option after the expiration of any statutory right to cure the default, stating:
When you are in default and after expiration of any right you have under applicable state law to cure your default, we can require immediate payment of your outstanding balance under the Plan without giving you advance notice.
(Emphasis added.) Paragraph 10 of the security agreement also included a reposses[550]*550sion provision. The repossession provision authorized Norlarco to take possession of the collateral, sell the collateral, and apply the proceeds of the sale to the amount owed on the loan. The borrower would then be liable for any remaining deficiency. In pertinent part, the repossession provision stated:
You agree [Norlareo] has the right to take possession of the property without judicial process if this can be done without breach of the peace.... After we have possession of the property, we can sell it and apply the money to any amounts you owe us.... If you have agreed to pay the advance, you will also have to pay any amount that remains unpaid after the sale money has been applied to the unpaid balance of the advance and to what you owe under the agreement.
18 Hassler made his last payment on the loan on April 21, 2001. He attempted to make payments in May 2001 and June 2001, but Norlareo reversed these credits in July 2001 because Hassler had insufficient funds to cover the payments. Norlareo repossessed the vehicle on October 30, 2001. At or around the time that Norlareo repossessed the vehicle, Norlarco sent Hassler an undated letter, entitled "NOTICE OF OUR INTENT TO SELL PROPERTY," which gave notice that it had repossessed the vehicle and that it intended to sell the vehicle sometime after November 10, 2001. The letter stated that the amount obtained from the vehicle's sale would reduce the amount Hassler owed and that Hassler would be liable for any deficiency remaining after the sale. The letter also notified Hassler that he could get his vehicle back before it was sold by paying Norlarco the full amount owed on the loan. It stated, "You can get the property back at any time before we sell it by paying us the full amount you owe (not just the past due payments), including our expenses." (Emphasis added.) The wording used in the letter was identical to the model language set forth in the "safe-harbor" provision found in section 4-9-614, C.R.S. (2011), which requires a creditor to provide a debtor with notice of the right to redeem the repossessed collateral before disposing of it.
T9 After a failed attempt to sell the vehicle through a consignment agreement with a car dealership, Norlarco sold the vehicle at auction on June 4, 2002. The vehicle sold for $17,500, and those proceeds were applied to the outstanding balance, which resulted in a deficiency of $11,637.11. In a letter dated June 4, 2002, Norlarco notified Hassler that he owed a deficiency balance in the amount of $11,637.11 and that this amount was due to Norlarco within five days, unless Hassler contacted Norlareco and agreed to a new installment plan.
110 Hassler did not pay, and in March 2008, Norlareo assigned Hassler's debt to Account Brokers for collection.2 Account Brokers filed suit against Hassler in Jefferson County Court on May 7, 2008, approximately five years and eleven months after the sale of the vehicle but more than six and a half years after Norlareo's repossession. As his only defense, Hassler asserted that the six-year statute of limitations set out in section 18-80-108.5(1)(a) barred Account Brokers' claim for recovery. Before the county court, the parties stipulated to all material facts, including the amount of the deficiency balance plus interest.3 Further, the parties stipulated that the sole issue before the county court was whether the statute of limitations barred Account Brokers claim.
1 11 In its December 2008 order, the county court magistrate ruled that the statute of limitations did not bar Account Brokers' action because the cause of action did not accrue until June 5, 2002, the day after the vehicle was sold, which was less than six years before Account Brokers filed its complaint. The court reasoned that the debt, which in this case was the deficiency balance, was not liquidated or determinable until the vehicle was sold or, alternatively, that Has-sler made his last payment on the debt when the vehicle was sold. The court found for [551]*551Account Brokers in the amount of $15,000 plus costs.
[12 On appeal, the district court affirmed the county court's judgment, also concluding that the cause of action accrued the day after the vehicle was sold because, until then, the debt was not liquidated or determinable:
Although the loan did have an acceleration clause that would have made the entire loan amount due on the date of default, Appellee Account Brokers' assignor Nor-lareo was acting in accordance with the [UCC], CRS. § 4-9-601 et. [sic] seq., when it mitigated its damages by disposing of the collateral in a "commercially reasonable manner" and attempting to collect only deficiency debt rather than the entire loan amount. Therefore, the debt was not liquidated or of a determinable amount until the deficiency amount was determined after the car was sold on June 4, 2002, making June 5, 2002 the date that the cause of action accrued.
Based on this reasoning, the district court concluded that Account Brokers timely filed its claim within the six-year statute of limitations contained in section 18-80-108.5(1)(a).
113 Hassler petitioned this court for further review, and we granted certiorari.4
III. Analysis
14 Upon review, we disagree with the district court and hold that this action was time-barred because the balance sought by Account Brokers became due when Norlar-co unilaterally accelerated the debt by repossessing the vehicle and demanding repayment in full in the undated repossession letter. We reach this conclusion by first interpreting the six-year statute of limitations in section 183-80-108.5, which in turn is defined in part by section 13-80-108(4) (defining when a cause of action for a debt accrues), and hold that the statute of limitations for the recovery of a debt under a security agreement is triggered whenever the debt "becomes due" by the terms of the agreement. Next, we hold that, pursuant to the parties' security agreement, the remaining balance of Hassler's debt became due when Norlareo invoked its option to accelerate the debt, as evidenced through the unequivocal act of repossessing the vehicle and demanding repayment in full. Under both the relevant statutes and the express terms of the parties' security agreement, Norlarco was entitled to invoke its unilateral option to accelerate the present debt and did so when it informed Has-sler that he could only retake possession of his repossessed property by paying the entire balance of the loan-and not merely the outstanding balance of the lapsed monthly installments. Accordingly, because this acceleration occurred more than six years before the initiation of the present action, we hold that the present claim is time-barred.
A. The Statute of Limitations
"15 Initially, we must interpret the statutory scheme to determine when the relevant statute of limitations was triggered in the instant case. Statutory interpretation involves a question of law, which we review de novo. Smith v. Exec. Custom Homes, Inc., 230 P.3d 1186, 1189 (Colo.2010). When construing a statute, our goal is to determine and give effect to the intent of the General Assembly. People v. Perez, 238 P.3d 665, 669 (Colo.2010). Before resorting to canons of statutory interpretation, we look to the plain and ordinary meaning of the words in a statute. Id. If the statutory provisions are [552]*552clear, we apply their plain and ordinary meaning. CLPF-Parkridge One, L.P. v. Harwell Invs., Inc., 105 P.3d 658, 660 (Colo.2005).
1 16 Of the several statutes relevant to this case, we begin with the statute of limitations set forth in section 18-80-108.5(1)(a). That section applies a six-year statute of limitations to specified types of actions to recover a debt, including all actions to enforce the rights set forth in an instrument securing the payment of debt:
(1) The following actions shall be commenced within six years after the cause of action accrues and not thereafter:
(a) All actions to recover a liquidated debt or an unliquidated, determinable amount of money due to the person bringing the action, all actions for the enforcement of rights set forth in any instrument securing the payment of or evidencing any debt, and all actions of replevin to recover the possession of personal property encumbered under any instrument securing any debt....
§ 183-80-108.5(1)(a) (emphasis added). By its terms, section 18-80-108.5(1)(a) states that the six-year statute of limitations for an action based upon the rights set forth in an instrument securing the repayment of a loan is triggered on the date that "the cause of action accrues." Id.; see also Nagy v. Landau, 807 P.2d 1227, 1228 (Colo.App.1990) (stating that section 18-80-108.5 requires "all actions of debt founded upon any contract ... to be commenced within six years after the cause of action accrued").
T17 To determine when the present cause of action acerued, we next turn to section 13-80-108, which sets forth multiple provisions that establish the acerual date for different types of civil actions. Pertinent here, subsection 13-80-108(4) applies to causes of action to recover a "debt, obligation, money owed, or performance" and states that such actions "shall be considered to accrue on the date such debt, obligation, money owed, or performance becomes due." § 13-80-108(4) (emphasis added).
$18 Hence, construing sections 13-80-108.5(1)(a) and 13-80-108(4) together, the statute of limitations for a debt owed pursuant to the rights set forth in a security instrument for the repayment of debt begins to run when the action acerues, which occurs on the date that the debt becomes due. Therefore, in order to determine when the statute of limitations began to run in the present matter, we must ascertain when the remaining balance of the debt that Hassler owed to Norlarco became due.
119 Here, our analysis departs from that of the district court. The district court correctly held that section 13-80-108.5(1)(a) is the appropriate statute for determining when the present statute of limitations period began to run. However, in determining when this "cause of action acerue{d]," rather than look to section 13-80-108(4), the district court erroneously applied the first clause of section 13-80-108.5(1)(a), which pertains to "[all actions to recover a liquidated debt or an unliquidated, determinable amount of money due." Thus, instead of asking when the present debt "became due," the district court incorrectly looked to see when the present debt became either liquidated or determinable. This was in error because the present action was not one to recover a liquidated or determinable debt, but was instead an action to enforce a debt secured under an instrument, as contemplated by the second clause of section 18-80-108.5(1)(a).
€ 20 Although no Colorado appellate court has ever explicitly parsed the clauses of seetion 183-80-108.5(1)(a), the plain meaning of the statutory text indicates that this action is one "for the enforcement of rights set forth in [an] instrument securing the payment of or evidencing [a] debt" and thus falls under the category of actions included in the second clause. See § 13-80-108.5(1)(a). This claim is an attempt by Account Brokers to recover the debt that Hassler incurred to purchase the vehicle under the parties' loan and security agreement. This instrument was executed contemporaneously with the purchase of the vehicle to memorialize the total amount that Hassler owed to Norlarco. See Mortg. Invs. Corp. v. Battle Mountain Corp., 70 P.3d 1176, 1184-85 (Colo.2003) (applying, with no discussion, the second clause of seetion 18-80-108.5(1)(a) to a debt secured un[553]*553der a promissory note); Tivoli Ventures, Inc. v. Bumann, 870 P.2d 1244, 1246 (Colo.1994) (same).
121 Thus, the date on which the present action accrued does not depend on whether Hassler's debt was liquidated or determinable.5 Instead, as clearly set forth in section 13-80-108(4), an action for the recovery of debt, like that at issue in the present matter, must be made pursuant to the terms of the parties' agreement and accrues on the date that the debt became due.
B. Acceleration of the Debt and Accrual of the Claim
1 22 Accordingly, we now turn to the question of when the portion of Hassler's debt that is now sought by Account Brokers "became due." As the framework for our analysis, we begin by acknowledging the manner in which a statute of limitations must be applied to obligations that are to be repaid in installments. The general rule provides that "[a] separate cause of action arises on each installment, and the statute of limitations runs separately against each." 31 Richard A. Lord, Williston on Contracts § 79:17 (4th ed. updated 2011); see also In re Church, 833 P.2d 813, 814-15 (Colo App.1992); Bay Area Laundry & Dry Cleaning Pension Trust Fund v. Ferbar Corp. of Cal., 522 U.S. 192, 208-09, 118 S.Ct 542, 189 LEd.2d 553 (1997). However, if an obligation that is to be repaid in installments is accelerated either automatically by the terms of the agreement or by the election of the creditor pursuant to an optional acceleration clause-the entire remaining balance of the loan becomes due immediately and the statute of limitations is triggered for all installments that had not previously become due. See Lord, supra, at §§ 79:17,;18; In re Church, 888 P.2d at 815; Bay Area Loundry, 522 U.S. at 208-09, 118 S.Ct. 542.
123 Both Hassler and Account Brokers agree that the security agreement contained an optional acceleration clause that could be unilaterally invoked by the creditor following default and the expiration of the debtor's right to cure. Thus, the relevant inquiry for determining when the present action accrued is whether Norlarco exercised its option to accelerate Hassler's debt. If Norlarco did accelerate the debt, then the ultimate issue becomes on what date did this occur and trigger the statute of limitations governing the present action. Hassler argues that Norlareo invoked the optional acceleration clause by repossessing the vehicle and demanding full payment on the entire balance of the loan in its undated repossession letter. Conversely, Account Brokers contends that acceleration did not occur until the repossessed vehicle was sold and Norlar-co sent Hassler a demand for the deficiency balance.
$24 "In the case of an acceleration provision exercisable at the option of the [creditor], the [creditor] must perform some clear, unequivocal affirmative act evidencing his intention to take advantage of the accelerating provision." Moss v. McDonald, 772 P.2d 626, 628 (Colo.App.1988). Colorado appellate courts have only considered this issue on two prior occasions, and in each instance the actions of the creditor were held not to amount to an unequivocal act of acceleration. In Moss v. MeDonald, a panel of the court of appeals held that, despite the fact that that case involved an acceleration provision that by its own terms allowed for the debt to be accelerated "without demand or notice," some affirmative act was still required on the part of the creditor to put the debtor on [554]*554notice that the debt had been accelerated. 72 P.2d at 628. Following the same reasoning, another panel of the court of appeals held in Bauer Development Co. v. Nu-West, Inc. that this unequivocal notice requirement was not satisfied by two letters sent by a creditor threatening foreclosure if the debtor did not make payment on the outstanding balance of the installments that had already become due. 757 P.2d 1149, 1150 (Colo.App.1988).
1 25 Although neither Moss nor McDonald contained significant analysis of why a clear, unequivocal act is necessary to invoke an optional acceleration clause, this principle is consistent with that adopted by a majority of other states. See, eg., Am.Jur.2d, Bills and Notes § 170; U.S. v. Feterl, 849 F.2d 354, 357 (8th Cir.1988); KIXX, Inc. v. Stallion Music, Inc., 610 P.2d 1385, 1388-89 (Utah 1980); State See. Sav. Co. v. Pelster, 207 Neb. 158, 296 N.W.2d 702, 706 (1980). These jurisdictions require that the "exercise of the option ... be made in a manner so clear and unequivocal as to leave no doubt as to the holder's intention and to apprise the maker effectively of the fact that the option has been exercised." 5 A.L.R.2d 968, § 4[al.
126 At the county court, the parties stipulated that Norlareo repossessed the vehicle on October 30, 2001, and sent Hassler an undated letter on or shortly after the date of repossession.6 In this letter, Norlareo informed Hassler that it was planning to invoke its contractual right to sell his repossessed property and expressly stated: "You can get the property back at any time before we sell it by paying us the full amount you owe (not just the past due payments ), including our expenses." (Emphasis added). At this point, Norlareo held possession of the vehicle and Hassler was on notice that he could only regain possession of the vehicle by paying the full amount of the loan and not merely by paying his missed installments to become current on the loan. Thus, it was on this unknown date that Norlareo elected to consolidate the remainder of the loan and claimed this entire balance against Hassler.7 We hold, as a matter of law, that Norlareo's repossession of the vehicle coupled with this demand for full payment left no doubt as to Norlarco's intention and apprised Hassler of the fact that Norlareo was accelerating the debt. Consequently, Norlareo's affirmative acts constituted a clear, unequivocal intent to accelerate all remaining installments due under the parties' agreement.8
T 27 Account Brokers makes three alternative arguments as to why Norlareo's repossession and demand for full payment did not amount to acceleration: (1) the undated letter merely parroted the sample "safe-harbor" language provided in section 4-9-614(a)(8) and, thus, its adherence to this legal obligation cannot be used to evince a subjective intent to accelerate; (2) any attempt to accelerate could not have been valid because the record does not contain evidence that Norlar-co first provided Hassler with notice of the right to cure as required by the Uniform Consumer Credit Code (UCCC) and the terms of the parties' security agreement; and (8) even if the repossession and the undated letter evinced an intent to accelerate, Norlareo's actions were equivocal as evidenced by the monthly statements that it [555]*555continued to send Hassler, which showed that his monthly installments continued to lapse. We address each of these arguments below and ultimately find each unpersuasive.
128 First, Account Brokers argues that the demand for full payment on Hassler's debt in the undated repossession letter cannot be considered a manifestation of its unequivocal intent to accelerate because the language in the letter was copied from seetion 4-9-614(a)(8). Section 4-9-614(a)(8) sets forth sample language that a ereditor may use to fulfill its duty under the UCC to provide a debtor with notice of his or her right to redeem before a creditor may dispose of collateral. In contrast to the right to cure, which we discuss below, the right to redeem requires that a debtor be given the opportunity to pay off any outstanding balance and retake possession of repossessed collateral before the creditor sells it. § 4-9-614(a)(1). As explained in official comment 8 to section 4-9-614, this so-called "safe-harbor" language does not need to be included in a valid notice of the right to redeem; instead, the language is merely included in the statute as an aid to creditors to provide certainty that the form of notice they use will not later be found to have been insufficient. See § 4-9-614(a)(2) ("A particular phrasing of notification is not required.").
{29 Account Brokers argues that the inclusion of the "safe-harbor" language in the undated letter to Hassler cannot be viewed as evidence of Norlareo's subjective intent to accelerate Hassler's debt because Norlarco included the language solely to comply with its UCC duty to provide Hassler with notice of his right to redeem. Account Brokers contends that the letter did not amount to a demand for full payment, but instead merely informed Hassler of his right to redeem.
130 Irrespective of Norlareo's unknown subjective intent, we fail to see a distinction between a demand for full payment and notice that Hassler could only retake possession of his vehicle by paying the entire amount owed on the loan. With respect to the invocation of an optional acceleration clause, nothing in our case law nor the persuasive authority from other jurisdictions suggests that acceleration turns on the subjective intent of the creditor. Instead, whether acceleration is unequivocal should be viewed from the perspective of the debtor. See 5 AL.R2d 968, § 4[a] (explaining that the act must be so clear and unequivocal as "to leave no doubt" in the mind of the debtor that the creditor has elected to accelerate the debt).
I 31 Account Brokers claims that this is an unfair result because Norlareo was merely complying with its statutory duty to provide Hassler with notice of his right to redeem the repossessed collateral. Account Brokers contends that if providing notice of the right to redeem amounts to acceleration, then no creditor can ever foreclose on collateral without first accelerating the underlying debt, which it claims is antithetical to the flexibility that the UCC provides a creditor in selecting its remedy. This argument, however, ignores the fact that the "safe-harbor" language in section 4-9-614(a)(8) is merely provided as a model, and thus there is no statutory prohibition precluding a ereditor from fulfilling its obligation of providing notice of the right to redeem under section 4-9-614 without acceleration.9 This can easily be accomplished by informing the debtor that he or she may redeem the repossessed collateral by simply becoming current on the lapsed installment payments. Here, Norlarco did not state that Hassler could redeem by paying the missed installments and instead used the "safe-harbor" language, which demands that the debtor pay the entire balance of the loan and thus had the effect of accelerating the debt. We conclude that there could have been "no doubt" on the part of Hassler that the entirety of his loan was due following both repossession of his vehicle and receipt of the repossession letter. Therefore, Nor-[556]*556lareo invoked its contractual option to accelerate the remaining debt.
1 32 Second, Account Brokers argues that even if Norlarco attempted to accelerate the debt, any attempt to do so was improper under the terms of the parties' agreement and the UCCC requirement that a debtor receive notice of the right to cure at least twenty days before a debt repayable in installments may be accelerated. The acceleration clause in the parties' security agreement, found in Paragraph 10, stated: "When you are in default and after expiration of any right you have under applicable state law to cure your default, we can require immediate payment of your outstanding balance under the Plan without giving you advance notice." (Emphasis added). Thus, under the express terms of the parties' security agreement, Norlarco could not require payment of the remaining balance that had yet to become due until (1) Hassler defaulted and (2) Has-sler's statutory right to cure the default expired. In other words, although the parties stipulate that Hassler was in default in May 2001, the remaining installments that had yet to become due could not be validly accelerated and would not become due until Hassler's statutory right to eure had expired.
188 The requirement that Hassler be afforded an opportunity to cure his default prior to acceleration, as set forth in the parties' acceleration clause, is consistent with Colorado law, which requires that all consumer debtors receive such protection. § 5-5-111, C.RS. (2011). Under the UCCC, which applies in this case,10 the "right to cure" is a term of art intended to protect debtors that default on consumer eredit transactions. See id.; see also Aetna Fin. Co. v. Summers, 642 P.2d 926, 928 (Colo.1982). The right to cure is intended to provide a debtor that is in default with a statutory window to catch up on missed payments without being subjected to immediate acceleration or repossession. See § 5-5-111(1); Green Tree Fin. Serv. Corp. v. Short, 10 P.3d 721, 723 (Colo.App.2000). Under this protection, upon a default as defined by the terms of the parties' agreement, the creditor may not repossess the collateral or accelerate the debt until twenty days after providing the creditor with notice of the right to cure. § 5-5-111(1).
Thus, Account Brokers argues that Norlarco could not have validly accelerated Hassler's debt because the record does not reflect whether Norlareo provided Hassler with notice of his right to cure his default, as required by section 5-5-111(1), before repossessing the vehicle or accelerating the debt. This unknown fact, however, is irrelevant to the resolution of the present matter because, irrespective of whether Norlarco provided Hassler with notice of his right to cure, Account Brokers' present claim would be barred by the statute of limitations. If Nor-lareo did provide Hassler with notice of his right to cure, then Norlarco would have been entitled, under Colorado law and the terms of the parties' agreement, to accelerate the remaining debt when it did so in its undated letter. Conversely, if Norlareo failed to provide Hassler with notice of his right to cure, any subsequent attempt to accelerate was wrongful under both section 5-5-111(1) and the explicit terms of the parties' security agreement, and it would be improper to allow Norlareo's successor-in-interest to benefit from such wrongful conduct by now claiming that the debt was never properly accelerated and thus never accrued.
$85 Moreover, because this issue was not raised by Account Brokers before the county court, we hold that it was not preserved for appeal and accordingly decline to address it. Paine, Webber, Jackson & Curtis, Inc. v. Adams, 718 P.2d 508, 514 [557]*557(Colo.1986); Stevenson v. The Hollywood Bar & Café, Inc., 832 P.2d 718, 721 n. 5 (Colo.1992) ("Arguments never presented to, considered or ruled upon by a trial court may not be raised for the first time on appeal."). Thus, we deem any potential defects related to Hassler's statutory and contractual right to receive notice of his right to cure to be waived.
T36 Finally, Account Brokers argues that even if Norlarco's repossession and mailing of the undated foreclogure letter evinced an intent to invoke its contractual option to accelerate, the monthly statements that it continued to send Hassler showing that it had not accelerated rendered any prior attempt to accelerate equivocal-and thus legally ineffective. While the county court was presented with evidence that Norlarco sent monthly loan statements to Hassler following repossession for billing on the missed monthly installments, we hold that this later conduct was insufficient to reverse Norlarceo's prior acceleration. To determine whether the invocation of the acceleration clause was unequivocal, we look to see whether some act of the creditor amounted to a clear manifestation of its intent to accelerate. Moss, 772 P.2d at 628 ("[The obligee must perform some clear, unequivocal affirmative act evidencing his intention to take advantage of the accelerating provision."). Accordingly, the creditor's course of conduct following acceleration is irrelevant. Again, following repossession and receipt of the repossession letter, Hassler was on notice that he could only retake possession of his vehicle by repaying the entire amount owed on the loan. Any contradictory action that Norlareo may have later taken was insufficient to un-ring this bell.
T 37 Thus, we hold that Norlareo accelerated the remaining balance on the loan by demanding full payment in the repossession letter that it sent to Hassler shortly after repossessing his vehicle on October 80, 2001.
(38 Having determined the approximate date that Norlarco accelerated the remaining balance of the loan, we decline to address whether Norlareo's claim for the accelerated debt accrued on the date that the debt was accelerated or on the date that Norlarco was first permitted to accelerate the debt. This issue is irrelevant to the resolution of the present matter because the undated letter was sent more than six years before the initiation of the present action on May 7, 2008. Therefore, because either date was more than six years prior to the filing of the present action, we need not determine the precise date on which the present action accrued. Consequently, we reserve this issue for another day.11
[558]*558139 Thus, Norlareo's cause of action accrued and the statute of limitations was triggered on either the day Norlareo was first entitled to accelerate or the day that Norlar-co did in fact accelerate the debt in its undated letter sent shortly after repossession on October 30, 2001. Given that either date was more than six years before Account Brokers filed suit on May 7, 2008, the statute of limitations bars the present action.
IV. Conclusion
140 For these reasons, we reverse the district court's order. We remand the case to the district court to return it to the county court for proceedings consistent with this opinion.
Justice MARQUEZ dissents.
