389 Practical hints
Towing the vehicle
Warning!G
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
system
as that will be necessary to adequately
control the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert.
iTo signal turns while being towed with the
hazard warning flasher in use, switch on the igni-
tion and activate the combination switch for the
left or right turn signal in the usual manner – only
the selected turn signal will operate.
Upon canceling the turn signal, the hazard warn-
ing flasher will operate again.
Warning!G
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 ve-
hicle. Adapt your driving accordingly.
!When towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey in starter switch position2, the ve-
hicle 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.
To prevent the vehicle doors from locking, deac-
tivate the automatic central locking
(
page 143).
Towing of the vehicle should only be done using
the properly installed towing eye bolt. Never at-
tach tow cable, tow rope or tow rod to vehicle
chassis, frame or suspension parts.
iIf the battery is disconnected or discharged

the SmartKey will not turn in the starter
switch. For more information, see “Battery”
(
page 383) and “Jump starting”
(
page 386).

the gear selector lever will remain locked in
positionP. For information on manually un-
locking the transmission gear selector lever
see (
page 363).
