## 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 range in height from 1.7 mm to 2.2 mm, when the required minimum height is 3.2 mm.

## IV. Rule Requirements

                    Paragraph S5.5.5(d)(5) of FMVSS No. 135 includes 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. They have not been evaluated by the Agency and do not reflect the views of the Agency. Porsche describes the subject noncompliance and contends that the noncompliance is inconsequential as it relates to motor vehicle safety.

In support of its petition, Porsche submitted the following reasoning:

                    1.                     *Multi-Function Display:*                     In addition to the brake wear indicator required by FMVSS No. 135, the Porsche vehicles also have a multi-functional display that provides brake wear information. Information about brake wear is provided in this display, which is readily visible to drivers, on the subject vehicles. Although the brake wear message can be confirmed and then suppressed by the vehicle operator at the next ignition cycle, doing so would necessarily require the operator to read and understand the message. Therefore, it can be assured that the need to check the vehicle's brake lining wear has been received. The brake wear message is presented in a display that expresses the need to change the brake pads, with continued driving possible/permitted.                

                    2.                     *Conspicuous, Accurate Information:*                     The brake wear warning symbol is the correct color as required by paragraph S5.5.5 of FMVSS No. 135. The warning symbol lettering is red, and the lettering and background are of contrasting colors. This makes the symbol conspicuous to the driver, as does its readily visible position immediately adjacent to fuel, temperature, and other critical vehicle data displays. The information provided by the brake wear symbol is also correct; the brake lining wear detection ability of the vehicle is entirely functional and completely unaffected by the lettering size issue.                

                    3.                     *Uniform Height:*                     All letters in the brake wear warning indicator are capitalized, so the height is preserved across the width of the words “brake” and “wear,” making the words are more easily seen and read.                

                    4.                     *Owner's Manual:*                     Information about the brake wear warning symbol is displayed in the owner's manual, which ensures that vehicle owners understand the symbol despite the smaller size of the lettering. For instance, the Panamera owner's manual explains the symbol and notifies the vehicle owner to have the brake pads replaced immediately.                

                    5.                     *Labeling:*                     This type of labeling noncompliance is precisely the type that NHTSA generally finds more appropriate for a determination of inconsequentiality.                     *See,*                     Porsche Cars North America, Inc., Grant of Petition for Decision of Inconsequential Noncompliance, 85 FR 62365, 62366 (Oct. 2, 2020), where NHTSA states “We note that the noncompliance at issue concerns a failure to meet a performance requirement. The burden of establishing the inconsequentiality of a failure to comply with a                     *performance requirement*                     in a standard—as opposed to a                     *labeling requirement*                    —is more substantial and difficult to meet. Accordingly, the Agency has not found many such noncompliances inconsequential.” (Emphasis in original).                

                    6.                     *Issue Corrected:*                     The noncompliance issue has been corrected in production vehicles and all vehicles currently being produced meet applicable lettering height requirements.                

                    7.                     *NHTSA Precedent:*                     Finally, and most significantly, NHTSA precedent supports granting this petition. The described noncompliance is very similar to others that NHTSA has found to be inconsequential to motor vehicle safety.                     *See*81 FR 92964 (Dec. 20, 2016) (grant of inconsequentiality petition to General Motors for parking brake indicator labeling below the required size, where corresponding driver information was provided in the instrument cluster); 67 FR 72026 (Dec. 3, 2002) (grant of inconsequentiality petition to Mercedes-Benz, U.S.A, Inc., where some letters in brake indicator warning were smaller than the required size, but additional messaging was provided in a message center).                

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.

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, any decision on this petition only applies to the subject vehicles that Porsche no longer controlled at the time it determined that the noncompliance existed. However, any decision on 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.
