458 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 (except vehi-
cles with 4MATIC) only so far as necessary 
to have the vehicle moved to a safe loca-
tion 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 and the 
automatic central locking.
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 ve-
hicle 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 or 1). 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 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).  

459 Practical hints
Towing the vehicle
!
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 (ve-
hicles 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 electrohy-
draulic brake system
there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on 
the ground, make certain the SmartKey is in 
starter switch position2.
If the SmartKey is left in the 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, re-
move SmartKey from starter switch and re-
insert.
Warning!
G
The brake system requires electrical power 
to operate.
A malfunction in the vehicle’s power supply 
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. To brake, the driver 
must then apply significantly greater brake 
pedal pressure and depress the pedal much 
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the 
brake pedal. Brakes may only be applied to 
the front wheels. Stopping distance is in-
creased! Adapt your driving style according-
ly. For more information, refer to 
“Electrohydraulic brake system” 
(page 96).
With the engine not running, there is no 
power assistance for the steering system. In 
this case, it is important to keep in mind that 
a considerably higher degree of effort is nec-
essary to steer the vehicle. Adapt your driv-
ing accordingly. 

460 Practical hintsTowing the vehicle
iTo signal turns while being towed with 
the hazard warning flasher in use, turn 
SmartKey in starter switch to 
position2 and activate the combina-
tion switch for the left or right turn sig-
nal in the usual manner – only the 
selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
!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, or KEYLESS-GO* 
start/stop button in position2, the ve-
hicle doors lock if the left front wheel 
as well as the right rear wheel are turn-
ing at vehicle speeds of approximately 
9mph (15km/h) or more.
Switch off the tow-away alarm 
(page 103).
To prevent the vehicle door locks from 
locking, deactivate the automatic cen-
tral locking (
page 127). 
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 the vehicle chas-
sis, frame or suspension parts.
iThe gear selector lever will remain 
locked in positionP and the SmartKey 
will not turn in the starter switch if the 
battery is disconnected or discharged. 
For more information, see “Battery” 
(page 452) and “Jump starting” 
(page 456).
For information on manual unlocking of 
the gear selector lever, see 
(page 426).
