The temporary spare wheel is inflated to the maximum inflation pressure for
the vehicle » Fig. 157 on page 185.
›
Only use this temporary spare wheel to reach the nearest specialist garage,
as it is not intended for long-term use.
WARNING
■
Never drive with more than one spare wheel mounted!
■
Only use the spare wheel while absolutely necessary.
■
Never use the temporary spare wheel if it is damaged.
■
If the dimensions or design of the temporary spare wheel differ from the
fitted tyres, never drive faster than 80 km/h (or 50 mph).
■
Avoid accelerating at full throttle, sharp braking and fast cornering.
■
The snow chains cannot be used on the spare wheel.
■
Observe instructions on the warning sign of the emergency wheel.

Winter tyres
Fitting winter tyres will significantly improve the handling of your vehicle when
driving in wintry road conditions. Summer tyres have less grip on ice, snow and
at temperatures below 7 °C. This is especially true of vehicles fitted with wide
tyres or high-speed tyres.
In order 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 permissi-
ble maximum speed of these tyres is not exceeded even if the possible maxi-
mum speed of the vehicle is higher.
The speed limit for winter tyres can be set in the MAXI DOT display in the
menu item Winter tyres » page 45.
For the sake of the environment
Fit the summer tyres on again in good time as they provide better handling
properties, a shorter braking distance, less tyre noise, and reduced tyre wear
on roads which are free of snow and ice as well as at temperatures above 7 °C.
The fuel consumption is also lower.
Snow chains
When driving in wintry road conditions, snow chains improve not only traction,
but also the braking performance.
The use of snow chains on vehicles with front-wheel drive and on vehicles
with four-wheel drive differs.
Front-wheel drive
Snow chains must only be mounted on the front wheels.
For technical reasons, it is only permissible to fit snow chains with the follow-
ing wheel/tyre combinations.
Wheel size Depth (D) Tyre size
6J x 16 50 mm 205/55
7J x 16 45 mm 205/55
6J x 17 45 mm 205/50
All-wheel drive
Snow chains can be used on the front wheels as on vehicles with front-wheel
drive.
In order to increase the traction (start-up properties), the use of snow chains is
also technically permissible on the rear axle (this means on the front and rear
axle at the same time) for the following wheel/tyre combinations.
Wheel size Depth (D) Tyre size
6J x 16 50 mm 205/55
7J x 16 45 mm 205/55
6J x 17 45 mm 205/50
The use of snow chains is only technically permissible on the rear axle for the
following standard wheel/tyre combinations.
