Points to remember
G
Risk of accident
If you have the vehicle towed, you must use a
rigid towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the power supply
or the vehicle's electrical system.
The power steering and the brake force boos-
ter do not work when the engine is not run-
ning. Greater braking force will then be
required and brake pedal travel will be longer.
If necessary, depress the brake pedal with full
force.
Before towing away, make sure that the steer-
ing can be moved and is not locked. 386

! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported. !
Vehicles with 4MATIC* may not be towed
with the front or rear axle raised.
! The engine must be switched off (key in
ignition lock in position 0or position 1) if
the vehicle is being towed with the front
axle raised or if the parking brake is being
tested on a dynamometer. Otherwise,
intervention by ESP ®
could damage the
brake system.
X Turn the key to position 2(Y page 182) in
the ignition lock.
i On vehicles with KEYLESS GO*: use the
key instead of the start-stop button.
