For the sake of the environment
Under-inflated tyres will increase the fuel
consumption. -------------
We recommend always using either the tyre
pressure setting (D for partial loads or the
setting @for full loads.
Wheel bolts and rims
Wheel bolts
The wheel bolts should be clean and turn easily.
A special adapter is required to turn the anti­
theft wheel bolts* cc> page 2 73.
Rims Rims with a bolted rim flange* or bolted trim
parts* consist of several components. A special
technique is applied to bolt these components
together. Never attempt to repair or dismantle
them c:::>A.
A WARNING
If the wheel bolts have not been tightened or
serviced correctly, they can come loose, and
you could lose control of the vehicle -risk of
accident! For the correct tightening torque,
refer to cc> page 2 75, A�er changing a wheel.
- Make sure that the wheel bolts and threads
in the wheel hubs are always clean and free
from grease.
- Only use wheel bolts that are designed to
match the rims on your car.
- Always have damaged rims repaired by a
qualified workshop. Never attempt to repair
or dismantle rims yourself -risk of accident!
Winter tyres
In winter road conditions winter tyres will consid­
erably improve the car's handling. Due to their
type of construction (width, rubber compound,
tread pattern), summer tyres give less grip on ice
and snow.
� Winter tyres must be fitted on all four wheels . Wheels
� Only use winter tyres of the correct type ap­
proved for your vehicle.
� Please note that the maximum permissible
speed for winter tyres may be lower than for
summer tyres cc>.&_ . Your specialist retailer can
advise you of the maximum speed for your
tyres.
� After fitting the wheels you must always check
the tyre pressures cc> page 256.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm. The per­
formance of winter tyres is also severely impaired
by ageing, even if the tread is still much deeper
than 4 mm.
A WARNING
- Never exceed the maximum approved speed
for your tyres. This causes the tyres to over­
heat and can even result in a blow-out -risk
of accident!
- Always adapt your driving style to the pre­
vailing road and traffic conditions. Drive
carefully and reduce your speed on icy or
slippery roads. Even winter tyres lose their
grip on black ice.
@ For the sake of the environment
Summer tyres should be fitted again as
soon
as possible; they give better handling on
roads which are free of snow and ice. They are
quieter, do not wear so quickly and reduce
fuel consumption.
(© Note
All-weather tyres can also be used instead of
winter tyres. Please note that winter tyres
with the£ symbol are required by law during
the winter season in some countries.
Snow chains
Snow chains will improve braking ability as well
as traction in winter conditions.
� Snow chains can be used on the front wheels
only. This also applies to vehicles with four-
wheel drive*.

off/ putting on the wheel
Fig. 236 Wheel: Hexagonal socket for turning wheel bolts
Fig. 237 Wheel: Mounting pin in wheel bolt hole nearest
to the top
Taking off the wheel
� Using the hexagonal socket in the screwdriver
handle (provided in the vehicle's tool kit), un­
screw the top wheel bolt and place it on a clean
surface ¢ Fig. 236.
� Screw in the mounting pin (provided in the ve­
hicle's tool kit) by hand in place of the wheel
bolt ¢Fig. 2371
).
� Then
unscrew the other wheel bolts.
�Take off the wheel ¢(D. The mounting pin
stays where it is.
Putting on the wheel
When putting on a tyre with directional tread
pattern, refer to ¢page 275.
� Put on the wheel, using the mounting pin to
guide it into place ¢(D.
� Screw in the wheel bolts and tighten them
lightly using the hexagonal socket.

� 1}
Applies to vehicles with ceramic brake discs*: Use a sec-
� and
mounting pin* (from the tool kit) for the bottom hole
8 following the same procedure as described for the first
� mounting
pin. Mobility
� Then unscrew the mounting pin and tighten the
remaining wheel bolt lightly.
� Carefully lower the car with the jack*.
� Tighten the wheel bolts in diagonal sequence
with the box spanner.
The wheel bolts should be clean and turn easily.
Before putting on the wheel, inspect the condi­
tion of the wheel and hub mounting surfaces.
These surfaces must be clean before mounting
the wheel.
.&_ WARNING
Do not use the hexagonal socket in the screw­
driver handle to tighten the wheel bolts. It is
not possible to tighten the bolts to the re­
quired torque using the hexagonal socket -
risk of accident!
CD CAUTION
When removing/ fitting the wheel the rim
may hit and damage the brake disc/ceramic*
brake disc. For this reason, please take care
and get a second person to assist you.
Tyres with directional tread pattern
A directional tread pattern can be identified by
arrows on the sidewall that point in the direction
of rotation. Always note the direction of rotation
indicated when mounting the wheel. This is im­
portant so that these tyres can give maximum
grip and avoid excessive noise, tread wear and
aquaplaning.
To benefit from the advantages of tyres with this
type of tread pattern, the defective tyre should
be replaced and refitted as soon as possible so
that all tyres again rotate in the correct direction.
After changing a wheel
� Fit the hubcap or wheel bolt caps back on, as
required. ..,.
