406 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment. This method is pref-
erable to other types of towing.When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised 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 87) and deactivate the auto-
matic central locking (
page 148).
!Vehicles with automatic transmission:
Do not tow-start the vehicle.
!If the vehicle is towed with the front
axle raised, the engine must be shut off
(SmartKey in starter switch position0
or1). Otherwise, the ESP will immedi-
ately 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 dis-
tances up to 30 miles (50 km) and at a
speed not to exceed 30 mph
(50 km/h).

408 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 follow-
ing:
With the automatic central locking acti-
vated 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 approximately 9 mph
(15 km/h) or more.
Switch off the tow-away alarm
(page 87).
To prevent the vehicle doors from lock-
ing, deactivate the automatic central
locking (
page 148).
Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to vehicle chassis,
frame or suspension parts.
iIf the battery is disconnected or dis-
charged

the SmartKey will not turn in the
starter switch. For more informa-
tion, see “Battery” (
page 401)
and “Jump starting” (page 404).


the gear selector lever will remain
locked in positionP. For informa-
tion on manually unlocking trans-
mission gear selector lever, see
(page 380).
