Mercedes-Benz GL-Class: Trailer towing
When you attach a trailer, make sure you have correctly established the electrical connection. This can be accomplished by checking the trailer lighting. In this event, Blind Spot Assist is deactivated. The indicator lamp in the exterior mirrors lights up yellow and the Blind Spot Assist Currently Unavailable See Operator's Manual message appears in the multifunction display.
You can deactivate the indicator lamps in
the exterior mirrors.
To do so, switch off Blind Spot Assist when:
• the SmartKey is in position 2 in the
ignition lock.
• the engine is not running.
• the electrical connection to the trailer
has been established.
