Power consumption
General
Before beginning your journey, check the func‐
tion of the trailer rear lights.
When towing a caravan, keep the activation
times of power consumers short to avoid placing
an excessive load on the vehicle battery.
Trailer rear lights
The power output of the trailer's rear lights must
not exceed the following values:
▷ Turn indicators: 42 watt per side.
▷ Tail lights: 50 watt per side.
▷ Brake lights: 84 watt total.
▷ Rear fog lights: 42 watt total.
▷ Reversing lights: 42 watt total.
Towing a trailer
General
When the trailer socket is in use, some Driver As‐
sistance Systems are unavailable, or available to
a limited extent. A Check Control message is
shown where applicable.
In order to avoid malfunctions, activate towing a
trailer mode, see page
322 .
Safety notes
WARNING
Speeds in excess of approximately 80 km/h,
50 mph, can be enough to produce snaking
motion, depending on the design of trailers and
the loads they are carrying. There is a danger of
accidents or damage to property.
Keep to an appropriate speed when towing a
trailer. If the trailer starts to snake, brake imme‐
diately and make the necessary steering cor‐
rections as carefully as possible.
WARNING
The tyre inflation pressure must be adapted
because of the increased axle load when tow‐
ing a trailer. Driving with inadequate tyre infla‐
tion pressure can damage the tyres. There is a
danger of accidents or damage to property. Do
not exceed a speed of 100 km/h / 60 mph. In‐
crease the tyre inflation pressure of the towing
vehicle by 0.2 bar. Note the maximum possible
tyre inflation pressure stated on the tyre.
Upward gradients
General
In the interest of safety and to avoid holding up
other traffic, do not attempt to climb upward gra‐
dients steeper than 12 % when towing a trailer.
If higher trailer loads have been retrospectively
approved, the limit is 8%.
Driving off on upward gradients
The parking brake is automatically released
when the accelerator pedal is operated.
To prevent the vehicle from rolling back when
driving off, use the parking brake.
1. Shortly before driving off, pull and re‐
lease the switch.
The parking brake is engaged.
2. Accelerate sufficiently to drive off.
Downhill gradients
On downward gradients, a car/trailer combination
tends to start snaking earlier.
Before the downward gradient, shift down man‐
ually to the next-lowest gear and drive down‐
wards slowly.
