Ensure that the trailer safety chain can move

Towing a trailer
General information
When driving with a trailer or rear-mounted
luggage rack, some driver assistance systems
are unavailable or only available to a limited
extent. A Check Control message is displayed
where applicable.
Safety information
Warning
Depending on the design and loading of
trailers, they may begin swinging at speeds
exceeding approx. 50 mph/80 km/h. There
may be a risk of accidents or risk of damage
to property.
Adapt your speed when driving with a trailer.
Immediately brake in the case of swinging.
Apply necessary steering corrections as care-
fully as possible.
Warning
The tire inflation pressure must be adjusted
to the increased axle weight in trailer towing.
Driving with too low tire inflation pressure can
damage the tires. There may be a risk of
accidents or risk of damage to property. Do
not exceed a speed of 60 mph / 100 km/h.
Increase the tire inflation pressure of the tow-
ing vehicle by 0.2 bar. Note the maximum
possible tire inflation pressure indicated on
the tire.
