Resetting The System - BMW 328i xDrive Owner's Manual

Gray
The system cannot detect a puncture.
The reasons for this are as follows:
> TPM is being reset.
>
Interference from systems or devices that
use the same radio frequency.
> Malfunction.

Resetting the system

Each time a tire inflation pressure has been
corrected or a wheel or tire has been changed,
reset the system.
1. "Vehicle Info"
2. "Vehicle status"
3. "Reset TPM"
4. Start the engine – do not drive away.
5. Start the initialization using "Reset TPM".
6. Start driving.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the target
values to be monitored. The resetting is com-
pleted automatically as you drive. On the Con-
trol Display, the tires are shown in green and
"Status: TPM active" is displayed again.
You can stop driving at any time. The resetting
continues automatically when you resume driv-
ing.
If a flat tire is detected during the reset-
ting process, all tires are displayed in
yellow in the Control Display. The message
"Low tire!" is shown.<

Message for low tire inflation pressure
The warning lamps come on in yellow
and red. A message appears on the
Control Display. 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 220; 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.<
Vibrations or loud noises during driving
may indicate the final failure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result in an accident.
Do not continue driving; instead, contact your
BMW center.<
