The tires are shown in gray and "Resetting

After a few minutes of driving, the set tire infla-
tion pressures in the tires are applied as the set
values to be monitored. Resetting finishes dur-
ing driving. The tires are shown in green on the
Control Display.
If a flat tire is detected during resetting
and applying the tire inflation pressures,
all tires are shown in yellow on the Control Dis-
play. The message "Tire low!" is displayed.

Message with low tire inflation
pressure
The warning lamp lights up yellow. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1. Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2. Check whether your vehicle is equipped
with standard tires or run-flat tires.
You will recognize run-flat tires by a
circular symbol containing the letters
RSC on the side of the tire, refer to
page
227 . <
Standard tires
1. If all four wheels are shown in yellow, iden-
tify the damaged tire on the vehicle.
2. Replace the damaged wheel or wheels,
refer to Changing wheels on page
242 .
In contrast to a compact wheel, a spare wheel is
equipped with the necessary TPM electronics
and also monitored after mounting and after
resetting the system.
Have the tire replaced by a BMW center or a
workshop informed on handling TPM which
works according to BMW repair procedures
with correspondingly trained personnel.
Run-flat tires*
1. Cautiously reduce speed to below 50 mph/
80 km/h. Avoid severe braking and steering
maneuvers and do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page
227 , do not
continue driving. Continuing to drive with a
flat tire could cause severe accidents.

2. In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
> With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
> With a medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 95 miles/150 km
> With a full load:
4 or more persons, cargo bay full:
