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>
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

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,

- 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

� 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
page 256.
the tyre pressures cc>
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*.
