Towing other vehicles
General
Switch on the hazard warning lights, depending
on local regulations.
If the electrical system of the vehicle being
towed has failed, the vehicle must be made iden‐
tifiable to other road users, for instance by plac‐
ing a sign or the warning triangle in the rear win‐
dow.
Safety notes
WARNING
If the gross vehicle weight of the towing vehicle
is less than that of the vehicle to be towed, the
towing eye can be pulled off, or the vehicle may
no longer be controllable. There is a danger of
accidents. Make sure that the gross vehicle
weight of the towing vehicle is greater than the
weight of the vehicle to be towed.
NOTE
If the tow bar or the towing rope is not attached
correctly, other vehicle parts can be damaged.
There is a danger of damage to property. At‐
tach the tow bar or towing rope to the towing
eye correctly.
Tow bar
The towing eyes of both vehicles should be on
the same side.
If it is impossible to avoid attaching the tow bar at
an angle, note the following:
▷ Tow bar clearance may be limited when cor‐
nering.
▷ The tow bar will generate lateral forces if it is
attached at an angle.

Towing rope
Ensure that the towing rope is taut when the
towing vehicle drives off.
Use nylon ropes or straps, which will enable the
vehicle to be towed without jerking.

the vehicle.
The towing eye can be screwed into the front or
rear end of the vehicle.
The towing eye is located in the on-board tool
kit, see page 304.
▷ Only use the towing eye supplied with the ve‐
hicle and make sure that it is screwed in fully
and is tight.
▷ Only use the towing eye for towing on paved
roads.
▷ Avoid cross-loads on the towing eye, for ex‐
ample do not raise the vehicle by the towing
eye.
