328 Practical hintsTowing the vehicle
Towing the vehicleMercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front wheels raised (except
vehicles with 4MATIC) only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Use flatbed or wheel lift/dolly equip-
ment with SmartKey in starter switch
turned to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 79) and deactivate the auto-
matic central locking (
page 133).
!Vehicles with automatic transmission
and/or 4MATIC:
Do not tow-start the vehicle.!Vehicles with 4MATIC:
Do not tow with one axle raised. Doing
so could damage the transfer case,
which is not covered by the
Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground.
Observe instructions for towing the
vehicle with all wheels on the ground.
!If the vehicle is towed with the front
axle raised (not permissible for vehicles
with 4MATIC), the engine must be shut
off (SmartKey in starter switch
position0 or1). Otherwise the ESP will
immediately be engaged and will apply
the rear wheel brakes.
When towing the vehicle with all wheels
on the ground, the gear selector lever
must be in positionN (manual trans-
mission: gears disengaged) and the
SmartKey must be in starter switch
position2.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for
distances up to 30 miles (50 km) and
at a speed not to exceed 30 mph
(50 km/h).

330 Practical hintsTowing the vehicleWarning!
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.
!When towing the vehicle with all wheels
on the ground, please note the
following:
With the automatic central locking
activated and the SmartKey in starter
switch position2, the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
Switch off the tow-away alarm
(page 79).
To prevent the vehicle doors from
locking, deactivate the automatic
central locking (
page 133).
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.
iIf the battery is disconnected or
discharged

the SmartKey will not turn in the
starter switch. See notes on the
battery (
page 323) or on jump
starting (page 326).


the gear selector lever will remain
locked in positionP. See notes on
manually unlocking transmission
gear selector lever (
page 308).
