Towing the vehicle
Important!
When towing the vehicle, please, note the following:
With the automatic central locking activated and the
electronic key in starter switch position 2, the vehicle
doors lock if the left front wheel as well as the right rear
wheel are turning at vehicle speeds of approximately
9 mph (15 km / h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking. See the
individual setting menu “VEHICLE” – “AUTOMATIC
DOOR LOCK” on page 132.
Towing of the vehicle should only be done using the
properly installed towing eye bolt. Never attach tow
cable, tow rope or tow rod to vehicle chassis, frame
or suspension parts.
Notes:
The selector lever will remain locked in position “P” and
the electronic key cannot be turned in the starter switch
if the battery is disconnected or discharged. See battery
on page 336 or jump starting on page 338.
Transmission selector lever, manually unlocking, see
page 344.
Wa r n i n g !
Prior to towing the vehicle with all wheels on the
ground, make certain that the electronic key is in
starter switch position 2.If the electronic key is left in the 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 electronic key
from starter switch and reinsert.

We recommend that the vehicle be transported using
flat bed equipment. This method is preferable to other
types of towing.
Important!
To prevent damage during transport, do not tie down
vehicle by its chassis or suspension parts.
Towing restrictions for vehicles with automatic
transmission:
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 starter switch
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 flange 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 starter switch turned to position 0.
Note:
To signal turns while being towed with hazard warning
flasher in use, turn electronic key in starter switch 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
flasher will operate again.
Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (electronic key in starter switch
position 0 or 1). Otherwise, the ESP will immediately be
engaged and will apply the rear wheel brakes.
Switch off the tow-away alarm (see page 46) as well as
the ESP (see page 274).
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.
