500 Practical hintsTowing the vehicle
!
To be certain to avoid additional dam-
age to the vehicle powertrain, however
you should observe the following:

With damage to the front axle

raise front axle


remove flexible drive shaft be-
tween rear axle and transfer
case


With damage to the rear axle

raise rear axle


tow vehicle with wheel lift or
dolly placed under front wheels


With damage to the transfer case

remove flexible drive shaft to
the drive axles
Always install new self-locking nuts
when reinstalling flexible drive shaft.
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 sys-
tem
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.
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
vehicle. Adapt your driving accordingly.iTo signal turns while being towed with
hazard warning flasher in use, turn the
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.
