## III. Noncompliance

Porsche explains that the noncompliance is that the subject vehicles are equipped with brake wear indicators that do not meet the minimum lettering height requirements, as specified in paragraph S5.5.5(d)(5) of FMVSS No. 135. Specifically, the lettering height for the brake wear indicators ranges in height from 1.7 mm to 2.2 mm, when the required minimum height is 3.2 mm.

## IV. Rule Requirements

                    Paragraphs S5.5.5(a) and S5.5.5(d)(5) of FMVSS No. 135 include the requirements relevant to this petition. Each visual indicator shall display a word or words in accordance with the requirements of FMVSS No. 101 (49 CFR 571.101) and FMVSS No. 135, which shall be legible to the driver under all daytime and nighttime conditions when activated. Unless otherwise specified, the words shall have letters not less than 3.2 mm (                    1/8                     inch) high and the letters and background shall be of contrasting colors, one of which is red. Words or symbols in addition to those required by FMVSS No. 101 and FMVSS No. 135 may be provided for purposes of clarity. If a separate indicator is provided to indicate brake lining wear-out as specified in S5.5.1(d), the words “Brake Wear” shall be used.                

## V. Summary of Porsche's Petition

                    The following views and arguments presented in this section, “V. Summary of Porsche's Petition,” are the views and arguments provided by Porsche and do not reflect the views of the Agency.                           ( print page 61007)                        Porsche describes the subject noncompliance and contends that the noncompliance is inconsequential as it relates to motor vehicle safety.                

Porsche believes that the subject noncompliance is inconsequential to vehicle safety. Porsche explains that, in addition to the required brake wear indicator, the affected vehicles have a multi-functional display that provides brake wear information and is readily visible to the driver. Porsche states that the brake wear message can be confirmed and then suppressed at the next ignition cycle, however, the operator would need to read and understand the message in order to do so. Porsche states that the brake wear indicator text is red, which is compliant and a contrasting color to the background of the text. Porsche believes that along with the color, the position of the text makes the brake wear indicator symbol conspicuous to the driver. The symbol is located adjacent to the fuel, temperature, and other vehicle data displays. Furthermore, Porsche states that the brake wear detection is functional and not affected by the noncompliant size of the text. Porsche adds that each letter of the text is capitalized, making it more easily seen and read by the driver due to the uniform height.

Porsche states that owners of the subject vehicles would understand the symbol despite the noncompliant text size because the owner's manual provided with the vehicle contains information about the brake wear warning symbol. Porsche notes that the subject noncompliance has been corrected in production vehicles.

                    Porsche contends that NHTSA has granted the prior petitions for similar noncompliances.[1]                                          Furthermore, Porsche says that NHTSA has stated in previous determinations that it generally finds labeling noncompliances like the subject noncompliance to be “more appropriate for a determination of inconsequentiality.” [2] 

Porsche concludes that the subject noncompliance is inconsequential as it relates to motor vehicle safety and that its petition to be exempted from providing notification of the noncompliance, as required by 49 U.S.C. 30118, and a remedy for the noncompliance, as required by 49 U.S.C. 30120, should be granted.

## VII. NHTSA's Analysis

                    In determining inconsequentiality of a noncompliance, NHTSA focuses on the safety risk to individuals who experience the type of event against which a recall would otherwise protect.[3]                                          In general, NHTSA does not consider the absence of complaints or injuries when determining if a noncompliance is inconsequential to safety. The absence of complaints does not mean vehicle occupants have not experienced a safety issue, nor does it mean that there will not be safety issues in the future.[4] 

The Agency concurs with Porsche that this noncompliance will not have an adverse effect on vehicle safety. Despite the letter height of the brake wear indicators being smaller than the 3.2 mm requirement, the affected vehicles include a multi-functional display which provides supplementary brake wear information that is located within the driver's direct field of vision, immediately adjacent to the fuel, temperature, other critical vehicle data displays. Although the additional brake warnings can be suppressed by the vehicle operator, the information is presented at every new ignition cycle and informs the driver of the need to change the brake pads while also recommending if continued driving is possible/advised. For as long as the brake warnings exist, the driver will be required to make a deliberate action after every new key cycle in order to suppress the additional brake warning messages. Finally, the additional brake warning symbols are accurately depicted and displayed in the correct colors, consistent with Table 1 of FMVSS No. 101, minimizing any confusion about the meaning of the indicators. Due to the aforementioned factors, the Agency concurs with Porsche that the subject noncompliance will have an adverse effect on vehicle safety and therefore recommends that this petition be granted.

## VII. NHTSA's Decision

In consideration of the foregoing, NHTSA finds that Porsche has met its burden of persuasion that the subject FMVSS No. 135 noncompliance in the affected vehicles is inconsequential to motor vehicle safety. Accordingly, Porsche's petition is hereby granted, and Porsche is consequently exempted from the obligation of providing notification of, and a free remedy for, that noncompliance under 49 U.S.C. 30118 and 30120.

NHTSA notes that the statutory provisions (49 U.S.C. 30118(d) and 30120(h)) that permit manufacturers to file petitions for a determination of inconsequentiality allow NHTSA to exempt manufacturers only from the duties found in sections 30118 and 30120, respectively, to notify owners, purchasers, and dealers of a defect or noncompliance and to remedy the defect or noncompliance. Therefore, this decision only applies to the subject vehicles that Porsche no longer controlled at the time it determined that the noncompliance existed. However, the granting of this petition does not relieve vehicle distributors and dealers of the prohibitions on the sale, offer for sale, or introduction or delivery for introduction into interstate commerce of the noncompliant vehicles under their control after Porsche notified them that the subject noncompliance existed.
