Maximum speed
If a tyre is damaged you can continue driv-
ing, but do not exceed a maximum speed of
80 km/h, 50 mph.
Continuing driving with a flat tyre
Observe the following if you continue driving
with a flat tyre:
1. Avoid heavy braking and sudden steering
manoeuvres.
2. Do not exceed a speed of 80 km/h,
50 mph.
3. At the next opportunity, check the tyre infla-
tion pressure in all four tyres.
Possible driving distance with a deflated tyre
The possible driving distance varies depending
on the load and stresses the vehicle is subjec-
ted to, for example speed, the nature of the
road surface and the outside temperature. The
driving distance may be shorter but can be in-
creased if a careful driving style is adopted.
With a moderate load and with low stress,
the vehicle can be driven for up to 80 km,
50 miles.
Driving properties with damaged tyres
Driving with damaged tyres changes the vehi-
cle's handling characteristics and may lead to
situations such as the following:
▷ The vehicle losing traction more quickly.
▷ Longer stopping distances.
▷ Different self-steering properties.
Adapt your driving style. Avoid abrupt steering
or driving over obstacles, for example kerbs or
potholes.
Final tyre failure
Vibration or loud noises during the journey
may be an indication that the tyre has finally
failed.

Wheels and tyres
Reduce your speed and stop the vehicle. Parts
of the tyre may detach, which might lead to an
accident.
Do not continue driving, but instead contact a
Service Partner of the manufacturer or another
qualified Service Partner or a specialist work-
shop.
System limits
Temperature
The tyre inflation pressure depends on the
temperature of the tyre.
The tyre inflation pressure increases as the
tyre air temperature increases, for example
while driving or when exposed to sunlight.
The tyre inflation pressure decreases when the
tyre air temperature drops.
Due to the given warning thresholds, therefore,
this behaviour may cause a warning to be trig-
gered when significant temperature drops oc-
cur.
After a temperature-related warning, the nom-
inal pressures are displayed again on the con-
trol display after driving a short distance.
Sudden tyre pressure loss
No warning can be given by the system in
the event of extreme, sudden tyre damages
caused by external factors.
Reset not carried out
Tyres with special approval: the system will not
function correctly if a reset has not been car-
ried out, for example, a flat tyre may be repor-
ted even though the tyre pressure is correct.
