A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Complaint Consistently reproducible erroneous parktronic warnings from front. Cause The parking sensors are detecting the front brush guard. Remedy Complaint must be consistently reproducible. NOTE: The parking system serves solely as an aid. Please review both the system function and system limitations as shown in the Operator's Manual. Certain environmental factors can affect system functionality such as hot exhaust gases or extreme heat, sensor interference, or other outside influences or aftermarket modifications. If after verifying the complaint is consistently reproducible: 1. Remove the brush guard and verify the park distance sensors function as expected. 2. Reinstall brush guard and adjust so that it is as far away from the park sensors as possible. Typically only small adjustments are possible. 3. Check function. If the concern is still consistently reproducible, please apply clear matte film to the locations as shown below at a minimum, although the clear matte film may be applied to the whole brush guard.
