i Vehicles without spare wheel are not
factory-equipped

with the tools required for
a wheel change such as a jack or a wheel
wrench. Some tools required for a wheel
change are specific to your vehicle.
Contact an authorized Mercedes-Benz
Center to obtain the tools approved for
your vehicle. This section describes the
wheel change using the tools approved and
recommended for your vehicle. Lifting the vehicle G
Warning!
When jacking up the vehicle, only use the jack
which has been specifically approved by
Mercedes-Benz for your vehicle.
The

jack is designed exclusively for jacking up
the vehicle at the jack take-up brackets built
into both sides of the vehicle. Make sure the
jack arm is fully seated in the jack take-up
bracket. The jack must always be vertical
when in use, especially on inclines or
declines.
The jack is intended only for lifting the vehicle
briefly for wheel changes. It is not suited for
performing maintenance work under the
vehicle. To help avoid personal injury, use the
jack only to lift the vehicle during a wheel
change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under the
vehicle.
Always engage the parking brake firmly and
block the wheels with wheel chocks or other
sizeable objects before raising the vehicle
with the jack. Do not disengage the parking
brake while the vehicle is raised.
Make sure that the ground on which the
vehicle is standing and where you place the
jack is solid, level and not slippery. If
necessary, use a large underlay. On slippery
surfaces, such as tiled floors, you should use
a non-slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack. 324

G
Warning!
Always replace wheel bolts that are damaged
or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be
repaired immediately. Do not continue to
drive under these circumstances! Contact an
authorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect wheel bolts or improperly tightened
wheel bolts can cause the wheel to come off.
This could cause an accident. Make sure to
use the correct wheel bolts. G
Warning!

Other wheel bolts may come loose.
Do not tighten the wheel bolts when the
vehicle is raised. Otherwise the vehicle could
fall off the jack. Wheel bolt

collapsible tire will damage the vehicle’s
brakes. G
Warning!

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

Towing with all wheels on the ground
G
Warning!
If circumstances require towing the vehicle
with all wheels on the ground, always tow with
a tow bar if:
R the engine will not run
R there is a malfunction in the brake system
R there is a malfunction in the power supply
or in the vehicle’s electrical system
This is 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 position 2.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.
X Make sure the ignition is switched on.
X With the vehicle at a standstill, depress the
brake pedal and keep it pressed.
X Shift the automatic transmission into
neutral position N.
X Release the brake pedal.
X If engaged, release the parking brake.
X Switch on the hazard warning flasher
(Y page 101).
! Keep in mind that it is important to have
the ignition switched on. Removing the
SmartKey from the starter switch or
opening a front door with the ignition
switched off will automatically shift the
automatic transmission into park position
P.
! 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). i
While being towed with the hazard
warning

flasher in use, use the combination
switch in the usual manner to signal turns.
Only the selected turn signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again. Stranded vehicle
Freeing a stranded vehicle, on which the
wheels are dug into sand or mud, should be
done with the greatest of care, especially if
the vehicle is heavily loaded.
Note the following when freeing a stranded
vehicle:
R Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
R Never try to free a vehicle that is still
coupled to a trailer.
R If

possible, a vehicle equipped with a trailer
hitch receiver should be pulled backward in
its own previously made tracks. Fuses
Introduction
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating. G
Warning!
Only use fuses approved by Mercedes-Benz
with
the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center. 340
