▶ Be particularly observant when driving.
▶ The emergency spare is inflated to the maximum inflation pressure for the
vehicle » page 217 .
▶ The tyre inflation pressure of the spare wheel R 18 is 4.2 bar.
▶ Only use this temporary spare wheel to reach the nearest specialist garage,
since it is not intended for permanent use.
If you need to use a spare wheel, make sure to fit a standard wheel of the ap-
propriate dimensions and design as soon as possible.
In vehicles with tyre pressure monitoring, save tyre pressure values » page 183.WARNING■
Never drive with more than one spare wheel mounted!■Only use the spare wheel while absolutely necessary.■
Avoid accelerating at full throttle, sharp braking and fast cornering.
■
The snow chains cannot be used on the spare wheel.
