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.iThe gear selector lever will remain
locked in positionP and the SmartKey
will not turn in the starter switch if the
battery is disconnected or discharged.
For more information, see “Battery”
(page 351) and “Jump starting”
(page 354).
For information on manually unlocking
transmission gear selector lever, see
(page 327).
iTo signal turns while being towed with
hazard warning flasher in use, turn
SmartKey in starter switch to
position2 and activate combination
switch for left or right turn signal in
usual manner – only the selected turn
signal will operate.
Upon canceling the turn signal, the
hazard warning flasher will operate
again.
!When towing the vehicle with all wheels
on the ground, note the following:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, the vehicle doors
lock if the wheels are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
To prevent the vehicle doors from lock-
ing, deactivate the automatic central
locking (
page 141).
Towing of the vehicle should only be
done using the towing eye. Never at-
tach tow cable, tow rope or tow rod to
vehicle chassis, frame or suspension
parts.

the towing eyes for pulling the vehicle onto
a trailer or transporter.

tion N.

tion N.In case of transfer case damage or for
towing vehicle distances exceeding
30 miles (50 km)
The propeller shafts to the drive axles must
be removed.
In case of front axle damage

peller shaft between the rear axle and the
transfer case must be removed.

Freeing a stranded vehicle, on which the
wheels are dug into sand or mud, should
be done with the greatest of care, especial-
ly if the vehicle is heavily loaded.
Avoid pulling the vehicle jerkily or diago-
nally, since it could result in damage to the
chassis alignment.
Never try to free a vehicle that is still cou-
pled to a trailer.
If possible, a vehicle equipped with trailer
hitch receiver should be pulled backward
in its own previously made tracks.
