Towing the vehicle
Safety notes
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.
! To prevent damage during transport, do
not tie down vehicle by its chassis or
suspension parts.
If circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground
or rear axle raised only so far as necessary to
have the vehicle moved to a safe location
where the recommended towing methods
can be employed.
! Before towing the vehicle observe the
following instructions:
RDo not tow-start the vehicle. You could
otherwise seriously damage the
transmission which is not covered by the
Mercedes-Benz Limited Warranty.
RDo not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
RTowing of the vehicle should only be
done using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope or tow rod to the vehicle chassis,
frame or suspension parts.
GWarning!
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
vehicle. Adapt your driving accordingly.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
iIf the battery is disconnected or
discharged
Rthe transmission will remain in park

speed not to exceed 30 mph (50 km/h).
When towing the vehicle with the rear axle
raised, the wheels on the ground have to
move freely. Therefore follow the respective
steps below, after the rear axle being raised:
XSwitch on the hazard warning flasher
( Y page 252).XMake sure the transmission remains in
neutral position N. Observe instructions,
see “Shifting into neutral position N”
( Y page 263).!
Because the ESC operates automatically,
the engine and ignition must be shut off
(KEYLESS-GO start/stop button in position
0 or 1, or SmartKey in starter switch
position 0 or 1) when the electronic parking
brake is being tested on a brake test
dynamometer or when the vehicle is being
towed with the rear axle raised.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! Keep in mind that it is important for the
SmartKey to be left in starter switch with
the ignition switched off. As soon as the
SmartKey is removed from the starter
switch the transmission will shift to park
position P.

GWarning!
When there is a malfunction in the brake
system, the vehicle must be towed using a tow
bar.
Before towing make sure the steering wheel
is unlocked and can be moved.
The vehicle must not be towed when the
power supply or the vehicle’s electrical
system are malfunctioning.
GWarning!
While the vehicle is being towed,
R the engine may turn off
R the electrical system may fail
R the battery voltage may drop too far.
All or any of this will block the rear axle.
This could cause an accident and injure you
and/or others.
! You must not use the KEYLESS-GO start/
stop button when towing the vehicle. Use
the SmartKey instead.
