Practical hints
Towing the vehicle
Warning!
G
With the engine not running, there is no
power assistance for the braking and steer-
ing systems. In this case, it is important to
keep in mind that a considerably higher de-
gree of effort is necessary to brake and
steer the vehicle. Adapt your driving accord-
ingly.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the key in starter switch
position
2, the vehicle doors lock if the
left front wheel as well as the right rear
wheel are turning at vehicle speeds of
approx. 9 mph (15 km/h) or more.
Switch off the tow-away alarm
(page 79).
To prevent the vehicle doors from lock-
ing, deactivate the automatic central
locking (
page 122).
Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to vehicle chassis,
frame or suspension parts.
iIf the battery is disconnected or dis-
charged

the key will not turn in the starter
switch. See notes on the battery
(page 294) or on jump starting
(page 297).


the selector lever will remain
locked in position P. See notes on
manual unlocking of gear selector
lever (
page 277).
