# Service campaign 26TC02

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

After calibrating a trailer and using the Trailer Backup Guide feature, subsequent use of this feature may result in a “Trailer not detected” message or a blank multimedia display that prevents the display of features such as the backup camera. The multimedia system returns to normal if the vehicle is turned off and on again with no trailer attached.
