Checking trailer lamps*
Automatic checking
After a trailer is connected electrically, it is possible to check that the trailer lamps are working via an automatic lamp activation. The function helps the driver check that the trailer lamps are working before starting off.
Switching off automatic checking
The automatic checking function can be switched off in the centre display.
Manual checking
If the automatic checking is switched off then it is possible to start the check manually.
Rear fog lamp on trailer
When connecting the trailer, the rear fog lamp may not light up on the car. In such cases, the rear fog lamp function switches to the trailer. Upon activation of the rear fog lamp, check therefore that the trailer is equipped with a rear fog lamp to travel safely.
Symbols and messages in the driver display
If one or more of the trailer's direction indicators or brake light bulbs is broken, the driver display shows a symbol and a message. Other lights on the trailer must be checked manually by the driver before setting off.
