The Tyre Pressure Loss Indicator must
always be correctly calibrated.
Driving on unpaved roads for long pe-
riods or a sporty driving style can tem-
porarily deactivate the Tyre Pressure Loss In-
dicator. In the event of a malfunction, the in-
dicator lamp will flash for about a minute and
then light up continuously. However, the in-
dicator lamp will go out when the road con-
ditions or driving style change.
Useful information about
wheels and tyres
Introduction to the topic
The tyres are the most heavily loaded and
most underestimated parts of a vehicle. Tyres
are very important as the narrow tyre surfa-
ces are the only contact between the vehicle
and the road.
The service life of tyres is dependent on tyre
pressure, driving style, handling and correct
fitting.
WARNING
New tyres or tyres which are old, worn
down or damaged cannot provide full levels
of vehicle control and braking efficiency.
·
Incorrect handling of wheels and tyres
can reduce vehicle safety and cause ac-
cidents and serious injuries.
·
All wheels must be fitted with radial
tyres of the same type, size (rolling cir-
cumference) and the same tread. Excep-
·
New tyres will have to be run in as they
will initially have reduced grip and brak-
ing effect. Drive particularly carefully for
the first 600 km (370 miles) in order to
prevent accidents and serious injury.
·
Check tyre pressures regularly when the
tyres are cold, and always keep to the
specified value. If the tyre pressure is
too low, it is possible that the tyre tem-
perature will increase to such an extent
when driving that the tread peels off
and the tyre bursts.
·
Check the tyres for damage and wear at
regular intervals.
·
Never drive with worn tyres or tyres that
are damaged (i.e. they have holes, cuts,
cracks or blisters). Driving with tyres in
this condition can result in burst tyres,
accidents and serious injuries. Worn or
damaged tyres must be replaced as soon
as possible.
·
Never exceed the top speed and load
permitted for the fitted tyres.
·
The effectiveness of the driver assist
systems and brake support systems de-
pends on the tyre grip.
·
If you notice unusual vibrations or if the
vehicle pulls to one side when driving,
stop the car immediately and check the
wheels and tyres for damage.
·
In order to reduce the risk of losing con-
trol of the vehicle, and the risk of acci-
dent and serious injury, never loosen the
bolts on rims with bolted-on rim rings.
·
Do not use wheels or tyres if you do not
know their history. Used wheels and
tyres may be damaged, even if the dam-
age is not visible. This can cause tyre
damage, tyre failure and loss of control
of the vehicle.
·
Even if they have not been used, old
tyres can suddenly lose pressure or
burst, especially at high speeds, and thus
cause accidents and serious injuries.
Avoid using tyres that are more than six
years old. If you have no alternative,
drive slowly and with extra care at all
times.
WARNING
If the wheels are incorrectly fastened or if
wheel bolts are missing, the wheels could
