Tyre damageRead and observe
on page 154 first.
We recommend checking your tyres and wheel rims for damage (punctures,
cuts, splits and bulges, etc.) on a regular basis.
Remove any foreign objects in the tyre tread immediately (e.g. small stones).
Foreign bodies which have penetrated into the tyre (e.g. screws or nails)
should not be removed and seek help from a specialist garage.
WARNINGNever drive with damaged tyres – there is the risk of an accident occurring.
CAUTION
The tyres must be protected from contact with substances such as oil, grease
and fuel, which could damage them. If the tyres come into contact with these
substances, then we recommend you have this checked out in a specialist
workshop.
Unidirectional tyres
Read and observe
on page 154 first.
The direction of rotation of the tyres is marked by arrows on the wall of the
tyre .
The indicated direction of rotation must be adhered to in order to ensure the
optimal characteristics of these tyres.
These characteristics mainly relate to the following. ▶ Increased driving stability.
▶ Reduced risk of aquaplaning.
▶ Reduced tyre noise and tyre wear.
Spare wheel
Read and observe
on page 154 first.
The size of the spare wheel is identical to that of the vehicle factory installedwheels.
After changing the spare wheel, the tyre pressure should be adjusted.
In vehicles with tyre pressure monitoring, save tyre pressure values » page 120.WARNING■
If, you get a puncture and a spare tyre has to be mounted with opposite
direction of rotation, then drive carefully. The best properties of the tyre
are no longer present 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.
Spare wheel
Read and observe
on page 154 first.
A yellow warning label is always displayed on the rim of the temporary spare
wheel.
Please note the following if you intend to use the temporary spare wheel. ▶ The warning label must not be covered after installing the wheel.
▶ Be particularly observant when driving.
▶ The spare is inflated to the maximum inflation pressure for the vehicle
» page 155 .
▶ The tyre inflation pressure of the spare wheel 125/70 R16 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 120.
WARNING■
Never drive with more than one temporary spare wheel mounted!■Only use the temporary spare wheel when absolutely necessary.■
Avoid accelerating at full throttle, sharp braking and fast cornering.
■
The snow chains cannot be used on the temporary spare wheel.
■
If the dimensions or design of the temporary spare wheel differ from the
tyres fitted, never drive faster than 80 km/h (or 50 mph).
■
Never use the emergency spare wheel if it is damaged.
■
Observe the instructions on the warning sign of the temporary spare
wheel.
