!
On vehicles fitted with a tyre pressure
monitor*, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
i Vehicles with a tyre pressure monitor*
If the positions of the wheels on the vehicle
are changed, the tyre pressure may be tem-
porarily displayed at the wrong position.
This is rectified after a few minutes of driv-
ing; the tyre pressures are then displayed
for the correct positions. Winter driving
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter. Winter tyres
Use winter tyres at temperatures below +7 °C
and on snow or ice-covered roads. Only then
can the effect of the ABS, BAS, 4ETS and
ESP ®
driving systems also be ensured in win-
ter.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with a tread depth of less than
4 mm must be replaced immediately. They
are no longer suitable for winter use and
can no longer provide sufficient grip. This
could cause you to lose control of your
vehicle and cause an accident.
Always observe the maximum permissible
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permissible speed than that of the vehicle, affix an appropriate warning
sign in the driver's field of vision. This can be
obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
Once you have fitted the winter tyres:
X
Check the tyre pressures (Y page 164).
X Restart the tyre pressure moni-
tor* (Y page 166). G
Risk of accident
If you fit the spare wheel when driving with
winter tyres, bear in mind that driving sta-
bility will be impaired due to unstable cor-
nering characteristics caused by the differ-
ent tyres. Therefore, you should adapt your
driving style and drive even more carefully.
Have the spare wheel replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop. Operation

Observe legal requirements. Changing a wheel and fitting the spare
wheel G
Risk of accident
If the spare wheel is more than six years
old, or it does not correspond to the regular
wheel type: have the spare wheel replaced
by a new wheel at the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
Never drive the vehicle with more than one
spare wheel fitted.
Vehicles with different tyre dimensions on
the front and rear axles: wheel and tyre size
of the spare wheel and normal wheel are
different. When using the spare wheel, the
handling characteristics are compromised.
Do not exceed the maximum speed of 80
km/h. G
Risk of accident
Vehicles with AMG equipment: when you fit
the spare wheel, make sure you observe the
following:
R the maximum speed of 80 km/h
R the prescribed tyre pressure
Preparing the vehicle X
Prepare the vehicle as described
(Y page 243).
X If a trailer is coupled, uncouple it.
X Remove the vehicle tool kit and the jack
(Y page 191).
X Remove the spare wheel from the spare
wheel bracket (Y page 192).
X Secure the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
items under the front and rear of the wheel
that is diagonally opposite the wheel you
wish to change.
X On downhill gradients: place chocks or
similar items under both wheels of the
other axle. Raising
the vehicle G
Risk of injury
The jack is designed only to raise the vehi-
cle for a short time while a wheel is being
changed.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar items as jacking supports.
Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted height.
Do not start the engine at any time while
the wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. when starting the engine, opening
or closing a door or the tailgate) and you
could be seriously injured. G
Risk of accident
If you fail to position the jack correctly, the
vehicle may: Practical advice

Do not place wheel bolts in sand or on a
dirty surface. This could cause damage to
the bolt and wheel hub threads.
X Remove the wheel.
Fit ting a new wheel G
Risk of accident
Replace damaged or corroded wheel bolts.
Never oil or grease wheel bolts. G
Risk of accident
If a wheel hub thread is damaged, you must
not drive the vehicle any further. Consult a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre or Service
24h for this purpose. In particular, work rel-
evant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop. G
Risk of accident
Only use wheel bolts that have been
designed for the wheel and the vehicle. For
safety reasons, Mercedes-Benz recom- mends that you only use wheel bolts which
have been approved for Mercedes-Benz
vehicles. Other bolts could work loose.
Do not tighten the wheel bolts completely
while the vehicle is still jacked up. The vehi-
cle could topple off the jack.
X Clean the wheel and wheel hub contact
surfaces.
X Place the wheel on the wheel hub and push
it on.
X Tighten the wheel bolts until they are fin-
ger-tight.
Lowering the vehicle X
Open the pressure release screw on the
jack using the pump lever (Y page 244) by
approximatel y one turn.
X Place the jack to one side. 1
–5 Wheel bolts
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted (1 to5). The tightening torque is
130 Nm . G
Risk of accident
Have the tightening torque checked imme-
diately after a wheel is changed. The wheels
could work loose if they are not tightened
to a torque of 130 Nm.
X Push the jack piston back in and close the
drain plug.
X Secure the faulty wheel by using the fas-
tening bolts to the exterior spare wheel
bracket. Practical advice

axle and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of damage to the rear axle
Have the propeller shaft between the front
axle and the transfer case removed.
Then have the vehicle towed with the rear axle
raised and with wheel rollers under the front
axle.
!
Always use new self-locking nuts when
fitting the propeller shafts.
i Consult a Mercedes-Benz Service Centre. Fuses
Notes on changing fuses
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart. A Mercedes-
Benz Service Centre will be happy to advise
you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have
the correct fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Otherwise, a circuit overload
could cause a fire. Have the cause traced
and rectified at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses are located in various fuse boxes:
R Main fuse box on the driver's side of the
dashboard
R Fuse box in the front-passenger footwell
R Fuse box in the transmission tunnel
R Fuse box in the battery case
Fuse allocation chart The fuse allocation chart is in the main fuse
box in the dashboard.
Spare fuses
Spare fuses are located in the main fuse box
on the dashboard.
