Warning!
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:
the engine will not run
there is a malfunction in the power
supply or in the vehicle's electrical sys-
tem
Prior to towing the vehicle with all wheels on
the ground, make sure the starter switch is
in position 2 ( page 40).
Warning!
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.

Practical hints
Towing the vehicle
!
When towing the vehicle with all wheels on
the ground, note the following:
With the automatic central locking activated and
the ignition in position 2 ( page 40), the vehicle
doors lock if the left front wheel is turning at a
speed of approximately 9 mph (15 km/h) or
above.
To prevent the vehicle doors from locking,
deactivate the automatic central locking
( page 126).
Towing of the vehicle should only be done using
the towing eye bolt. Never attach tow cable, tow
rope or tow rod to vehicle chassis, frame or sus-
pension parts.
