Replacing the wiper blades
G
Risk of accident
The windscreen will not longer be properly
wiped if the wiper blades are worn. This
could prevent you from observing the traffic
conditions, thereby causing an accident.
Replace the wiper blades twice a year, ide-
ally in spring and autumn. G
Risk of accident
The wiper arms could start moving and
cause an injury if you leave the windscreen
wipers switched on.
Remove the key from the ignition lock
before replacing the wiper blades.
! Under no circumstances should you open
the bonnet when a wiper arm is folded away
from the windscreen. Otherwise, you could
damage the bonnet.
Place wiper arms on the windscreen care-
fully if they do not have a wiper blade fitted.
They may otherwise damage the wind-
screen. !
Make sure that you touch only the wiper
arm of the windscreen wiper to avoid dam-
aging the windscreen wiper blades.

Remove the key from the ignition lock.
X Fold the wiper arm away from the wind-
screen until it engages.

from traffic on solid, non-slippery and level
ground.
X Switch on the hazard warning lamps.
X Deactivate the automatic door locking
(Y page 108).
X Position the wheels in the straight-ahead
position.
X Engage the steering wheel lock.
X Apply the parking brake.
X Move the selector lever to P.
X All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area whilst a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Switch off the engine.
X Remove the key from the ignition lock.

Close the driver’s door.
X Place the warning triangle ( Ypage 188) or

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

Thus, it is important to make sure that the

tive jacking points. Before positioning the
jack, remove any dirt that may have collec-
ted in the jacking points. Wheel wrench

By using the wheel wrench, loosen the
wheel bolts on the wheel you wish to
change by about one full turn. Do not
unscrew the bolts completely. Pump lever

i Never turn pressure release screw 2by
more than one to two revolutions. Other-
wise, hydraulic fluid could escape. X
Position the jack at the front and rear axle
carrier tubes The jack must always stand
vertically, even on slopes.
X Raise the vehicle by pumping (arrow) until
the tyre is three centimetres off the ground
at the most.

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

Cover the faulty wheel with the tyre cover
provided.
X Check the tyre pressure and correct it, if
necessary.
You will find a table of tyre pressures on the
inside of your vehicle's fuel filler flap. Battery
Notes on the vehicle battery
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
To prevent damage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Consult a Mercedes-Benz Service Centre if
you wish to leave your vehicle parked up for
a long period of time. G
Risk of injury
Comply with safety precautions and take
protective measures when handling batter-
ies. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the bat- tery. Avoid creating
sparks.
Battery acid is caustic.
Avoid contact with the
skin, eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a
face mask.
Immediately rinse acid
splashes off with clean
water. Consult a doctor if
necessary.
Wear eye protection.
Keep children away.
Observe this Owner's
Manual.
