Te ch n ica l

We recommend that the vehicle be transported using
flat bed equipment. This method is preferable to other
types of towing.
The vehicle may be towed with all wheels on the ground
and the selector lever in position “N” for distances up to
30 miles (50 km) and at a speed not to exceed 30 mph
(50 km/h). The electronic key must be in steering lock
position 2.
To be certain to avoid a possibility of damage to the
transmission, however, we recommend the drive shaft
be disconnected at the rear axle drive f lange for any
towing beyond a short tow to a nearby garage.
Do not tow with sling-type equipment. Towing with
sling-type equipment over bumpy roads will damage
radiator and supports.
Use wheel lift, dolly, or flat bed equipment, with
electronic key in steering lock turned to position 0.Note:
To signal turns while being towed with hazard warning
flasher in use, turn electronic key in steering lock to
position 2 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
f lasher will operate again.
Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (electronic key in steering lock
position 0 or 1). Otherwise, the ESP will immediately be
engaged and will apply the rear wheel brakes. Switch off
th e tow -away alarm (see page 44) a s well a s t he ESP (see
page 222).
Wa r n i n g !
With the engine not running, there is no power
assistance for the braking 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.

Window cleaning
Use a window cleaning solution on all glass surfaces. An
automotive glass cleaner is recommended.
