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
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:
R Do not tow-start the vehicle. You could
otherwise seriously damage the
automatic transmission which is not
covered by the Mercedes-Benz Limited
Warranty.
R Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
R Towing 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.
! 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. G
Warning!
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.
i If the battery is disconnected or
discharged
R the SmartKey will not turn in the starter
switch
R the automatic transmission will remain in
park position P
For more information see “Battery”
(Y page 333) or “Jump starting”
(Y page 336). Installing towing eye bolt
Depending on whether you are towing a
vehicle

or you are being towed, the towing eye
bolt can be screwed into threaded holes
which are located behind covers on each
bumper.
The towing eye bolt is supplied with the
vehicle tool kit, located in the cargo
compartment underneath the cargo
compartment floor (Y page 270).
X Take the towing eye bolt out of the space
underneath the cargo compartment floor. 338

. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding
the following on the tire’s sidewall:
R MO = Mercedes-Benz Original
equipment tires
R MOE

= Mercedes-Benz Original Extended
(tires with limited run-flat
characteristics) original equipment tires
Using tires other than those approved by
Mercedes-Benz may result in damage that
is not covered by the Mercedes-Benz
Limited Warranty.
For information on driving with MOExtended
tires, see the “Practical hints” section
(Y page 330).
