WARNING
■
If, you get a puncture and a spare tyre has to be mounted with opposite
direction of rotation, then drive carefully. The tyre no longer retains its opti-
mal characteristics 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.
■
Never use the temporary spare wheel if it is damaged.
