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 position 2.
If the SmartKey is left in starter switch
position 0 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.

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.

To signal turns while being towed with
hazard warning flasher in use, turn the
SmartKey in starter switch to
position 2 and activate combination
switch for left or right turn signal in

signal will operate.
