Wheel bolts
First read and observe the introductory information and safety warn-
ings on page 194.
Wheels and wheel bolts are matched to each other in terms of design. Each time
you fit other wheels - e.g. light alloy wheels or wheels with winter tyres - you
must therefore also use the matching wheel bolts of the correct length and
shape of spherical cap. This is essential to ensure that the wheels are tightly fit-
ted and that the brake system operates properly.
Winter tyres
First read and observe the introductory information and safety warn-
ings on page 194.
The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber
blend, tread pattern). This particularly applies to vehicles which are equipped with
low-profile tyres or high-speed tyres (code index H or V on wall of tyre).
To achieve the best possible handling properties, winter tyres must be fitted on
all 4 wheels, the minimum tread depth must be 4 mm and tyres must be no older
than 4 years.
Winter tyres of a lower speed category can be used provided that the permissible
maximum speed of these tyres is not exceeded even if the possible maximum
speed of the vehicle is higher.
For the sake of the environment
Fit the summer tyres on again in good time as they provide better handling prop-
erties, a shorter braking distance, less tyre noise, reduced tyre wear and lower
fuel consumption on roads which are free of snow and ice as well as at tempera-
tures above 7 °C.
Snow chains
First read and observe the introductory information and safety warn-
ings on page 194.

Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains improve not only traction, but also the
braking performance.
For technical reasons, it is only permissible to fit snow chains with the following
wheel/tyre combinations.
Wheel size Depth (D) Tyre size
7J x 16
a)
45 mm 205/55
6J x 16
a)
50 mm 205/55
6J x 17 45 mm 205/50
a)
Not valid for vehicles with 3.6 l/191 kW FSI engine.
Only use fine-link snow chains. They must not project more than 9 mm - includ-
ing the chain lock.
Remove the full wheel trims before installing the snow chains.
Observe the national legal regulations relating to the use of snow chains and the
maximum vehicle speed with snow chains.
CAUTION
The chains must be removed when driving on roads which are free of snow. They
adversely affect the handling of your vehicle, damage the tyres and are rapidly
destroyed.
