Wheels and tyres
234Wheel bolts
Wheel bolts must be tightened to the correct torque.The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped bolt
heads must be used. This ensures that wheels are fitted securely and that the
brake system functions correctly.
In certain circumstances, you may not use wheel bolts from a different car -
even if it is the same model ⇒page 204.
After the wheels have been changed, the tightening torque of the wheel bolts
should be checked as soon as possible with a torque wrench. ⇒ The tight-
ening torque for steel and alloy wheels is 120 Nm.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.•
The wheel bolts must be clean and turn easily. Never apply grease or oil
to them.
•
Use only wheel bolts which belong to the wheel.
•
If the torque of the wheel bolts is to o low, they could loosen whilst the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads could be damaged.Caution
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm.
Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyres (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle's regis-
tration documents. Use only radial winter tyres. All tyre sizes listed in the
vehicle documentation also apply to winter tyres.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒page 232, “New tyres and wheels” determines the
following speed limits : ⇒ ⇒
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
H max. 210 km/h
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 232, “New tyres and wheels”.

Compact temporary spare wheel*
The compact spare wheel (emergency wheel for vehicles
without the anti-puncture kit) should only be used when
strictly necessary.The temporary spare wheel is stored under the floor panel in the luggage
compartment and is attached by a thumbnut.
How to use the compact temporary spare wheel
Should you ever have a punctured tyre, the compact temporary spare wheel
is only intended for temporary use until you can reach a workshop. The
standard-size road wheel should be replaced as soon as possible.
Please note the following restrictions when using the compact temporary
spare wheel. This spare wheel has been specially designed for your vehicle,
thus, it cannot be changed with th e spare wheel from another vehicle.
No other type of tyre (normal summer or winter tyre) may be fitted on the
compact temporary spare wheel rim. Snow chains
For technical reasons, snow chains must not
be used on the compact tempo-
rary spare wheel.
If you should have a puncture on one of the front wheels when using snow
chains, fit the compact temporary spare in place of one of the rear wheels.
You can then attach the snow chains to the wheel taken from the rear and use
this wheel to replace the punctured front wheel.
WARNING
•
The tyre pressures must be checked and corrected as soon as possible.
The tyre pressure for the spare wheel is 4.2 bar. Failure to do so could result
in an accident.
•
Do not drive faster than 80 km/h. High er speeds can cause an accident.
•
Avoid heavy acceleration, hard braking and fast cornering, risk of acci-
dent.
•
Never use two or more compact spare tyres at the same time, risk of
accident.
•
No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.
Tyre repair kit
The tyre repair kit (for vehicles not including a spare wheel) is
stored under the floor panel in the luggage compartment.Your vehicle is equipped with the Tyre Mobility System “Tyre repair kit”.
The tyre repair kit consists of a contai ner with sealing compound to repair the
puncture and a compressor to generate the required tyre pressure. The kit will
reliably seal punctures up to a size of about 4 mm caused by the penetration
of a foreign body into the tyre.

Note•
Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.
Wheel changePreparation work
What you must do before changing a wheel.– If you have a flat tyre or puncture, park the vehicle as far away from the flow of traffic as possible. Choose a location that is as
level as possible.
– All passengers should leave the ve hicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Switch off the engine. Switch on the hazard warning lights.
–Apply the handbrake firmly.
– Engage the first gear, or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in position.
This is for your own safety and also warns other road users.
Caution
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so.Changing a wheelChange the wheel as described below
–Pull off the hub cap. Also refer to ⇒page 239.
– Slacken the wheel bolts.
– Raise the car with the jack in the corresponding zone.
– Ta k e o f f the wheel and then put on the spare wheel.
– Lower the vehicle.
– Tighten the wheel bolts firmly in diagonal sequence with the box
spanner.
–Replace the hub cap.

242Raising the vehicle
The vehicle must be raised with a jack to remove the wheel.
– Locate the jacking point under the door sill closest to the wheel
being changed ⇒fig. 179.
– Wind up the jack under the jacking point until the arm of the jack is directly below the vertical rib under the door sill.
– Align the jack so that the arm of the jack fits around the rib under the door sill and the movable base plate of the jack is flat on the
ground ⇒fig. 180.
– Raise the vehicle until the defective wheel is just clear of the ground.Recesses at the front and rear of the door sills mark the jacking points
⇒fig. 179. A position has been made for each wheel. Do not fit the jack
anywhere else.
An unstable surface under the jack may cause the vehicle to slip off the jack.
Therefore, the jack must be fitted on solid ground offering good support. Use
a large and stable base, if necessary. On a hard, slippery surface (such as
tiles) use a rubber mat or similar to prevent the jack from slipping.
WARNING
•
Take all precautions so that the base of the jack does not slip. Failure to
do so could result in an accident.
•
The vehicle can be damaged if the ja ck is not applied at the correct
jacking points. There is also a risk of injury since the jack can slip off
suddenly if it is not properly engaged.

– Pull on the cover and remove it from its allotment in the direction of the arrow ⇒ fig. 181.
– Once the cover has been released, it will remain connected to its strap so that is not lost.
Removing and fitting the wheel
For removal and fitting the wheel, the following tasks must be
completed.Change the wheel as described below after loosening the wheel
bolts and raising the vehicle with the jack.
Removing a wheel
– Unscrew the bolts using the hexagonal tool in the handle of the
screwdriver (vehicle tool) and place them on a clean surface
⇒ fig. 182.
Fitting a wheel
– Screw in the wheel bolts and tighten them lightly using the hexagonal socket in the screwdriver handle.
