Towing the vehicle
Towing the vehicle
Mercedes-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 the SmartKey in the 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 85) and deactivate the auto-
matic central locking (
page 145).
!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).

!
To be certain to avoid a possibility of 
damage to the drivetrain, however, we 
recommend the drive shaft be discon-
nected at the rear axle drive flange 
(vehicles with 4MATIC: disconnected at 
the front and rear axle drive flanges) for 
any towing beyond a short tow to a 
nearby garage.
Warning!
G
If circumstances require towing the vehicle 
with all wheels on the ground, always tow 
with a tow bar if:
the engine will not run
there is a malfunction in the power 
supply or in the vehicle’s electrical 
system
as that will be necessary to adequately 
control the towed vehicle.
Prior to towing the vehicle with all wheels on 
the ground, make sure the SmartKey is in 
starter switch position2.
If the SmartKey is left in starter switch 
position0 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.
iTo signal turns while being towed with 
the hazard warning flasher in use, 
switch on ignition and activate the 
combination switch for the left or right 
turn signal in the usual manner – only 
the selected turn signal will operate.
Upon canceling the turn signal, the 
hazard warning flasher will operate 
again.

Towing the vehicle
Warning!
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 85).
To prevent the vehicle doors from 
locking, deactivate the automatic 
central locking (
page 145).
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. For more informa-
tion, see “Battery” (
page 360) 
and “Jump starting” (page 363).
the gear selector lever will remain 
locked in positionP. For informa-
tion on manually unlocking the 
transmission gear selector lever 
see (
page 340).
