Spare wheel 143
Fit a wheel in the appropriate dimensions and design as soon as possible.
WARNING
■
If, in the event of a puncture, it is necessary to fit a spare wheel with a
tyre without a dedicated running direction or with the opposite direction of
rotation, drive carefully as the optimal characteristics of the tyre are no lon-
ger applicable in this situation.
■
If the dimensions or design of the spare wheel differ from the tyres fitted
to the vehicle (e.g. winter tyres or low-profile tyres), it must only be used
briefly in the event of a puncture and if an appropriately cautious style of
driving is adopted.
