BMW 550i xDrive Gran Turismo 2010 - Manual (Page 96)

The initialization automatically continues when
driving resumes.
Indication of a flat tire
The yellow warning lamp and the vehicle
symbol light up. A message appears on
the Control Display. In addition, a signal
sounds.
There is a flat tire or a major loss in tire inflation
pressure.
1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2. Check whether the vehicle is fitted with reg‐
ular tires* or run-flat tires*.
Run-flat tires are labeled with a circular sym‐
bol containing the letters RSC marked on
the tire sidewall.
Normal tires*
1. Identify the damaged wheel.
If an identification is not possible, please
contact the service center.
2. Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
Run-flat tires*
1. Carefully reduce your speed to a maximum
of 50 mph/80 km/h.
Avoid sudden braking and steering maneu‐
vers.
Do not exceed a speed of 50 mph/80 km/h.
Do not continue driving without run-
flat tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driv‐
ing may result in serious accidents.◀
2. Repair the puncture.
Continued driving with a flat tire
Possible driving distance with complete loss of
tire inflation pressure:
▷ With a light load: 1 to 2 people without lug‐
gage: approx. 90 miles/150 km.
▷ With a medium load: 2 people, trunk full, or
4 people without luggage: approx. 50 miles/
80 km.
▷ With a full load: 4 people, trunk full: approx.
30 miles/50 km.
If there is minor tire damage, especially on the
tire tread, the distance that you can travel with
the damaged tire can be extended.
After notification, inflate the damaged tire to a
maximum of 3.5 bar at the next opportunity.
Do not reinitialize the Flat Tire Monitor. The ex‐
isting flat tire notification will continue to act as
a reminder of the defective tire. The procedure
can be repeated several times.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center.◀
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.
