After several minutes of driving time, the
adjusted inflation pressures will be adopted as
nominal values. The resetting is completed
automatically as you drive. The indicator lamp
goes out after the system reset is completed.
You can stop driving at any time. The resetting
continues automatically when you resume driv-
ing.
Message for low tire inflation pressure
The warning lamps come on in yellow
and red. In addition, a signal sounds.
>There is a flat tire or substantial loss
of tire pressure.
> The system was not reset after a wheel
change and will thus issue warnings at the
last initialized inflation pressures.
Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steering
maneuvers. Do not exceed a speed of 50 mph/
80 km/h.
Do not continue driving if the vehicle is
not equipped with run-flat tires, refer to
page 142; continued driving could result in a
severe accident.<
Continuing to drive with a flat tire
Possible travel distance with complete tire
pressure loss:
> With a light load:
1 to 2 persons without luggage:
Approx. 155 miles/250 km
> With a medium load:
2 persons, cargo area full, or 4 persons
without luggage:
Approx. 95 miles/150 km
> With a full load:
4 persons, cargo area full:
Approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change, e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change.<
