453 Practical hints
Towing the vehicle
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.
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.
!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, or
KEYLESS-GO* start/stop button in position2,
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.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking
(
page 164).
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 the vehi-
cle 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 447) and “Jump starting”
(
page 450).
the gear selector lever will remain locked in
positionP. For information on manually un-
locking the transmission gear selector lever,
see (
page 412).
