Checking trailer lights*
Automatic check
When the trailer has been connected to the vehicle's electrical system, its lights can be checked by automatically activating them. This function helps the driver check that the trailer's lights are functioning correctly before starting to drive.
Disabling the automatic check
The automatic light check can be disabled in the center display.
Manual check
If the automatic check has been disabled, the check can be started manually.
Trailer rear fog light
When a trailer is connected, the vehicle's rear fog light may not illuminate and rear fog light functionality is instead transferred to the trailer. If this is the case, check to see if the trailer is equipped with a rear fog light before activating the vehicle's fog lights when driving with a trailer to help ensure safe operation.
Symbols and messages in the instrument panel
If one or more of the turn signals or brake lights on the trailer is not working, a symbol and message will be displayed in the instrument panel. The other lights on the trailer must be checked manually by the driver before the vehicle is driven.

If any of the trailer's turn signal lights is not working, the turn signal symbol in the instrument panel will also flash more quickly than normal.
