Tire Pressure Monitor Tpm - BMW M3 Owner's Manual

Controls
Indication of a flat tire
The warning lamps light up in yellow
and red. In addition, an acoustic sig-
nal sounds. There is a flat tire or a
major loss in tire pressure.
1. Reduce speed and stop the vehicle with
caution. Avoid sudden braking and steering
maneuvers.
If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious
When a flat tire is reported, the Dynamic Stabil-
ity Control DSC is activated.
Actions in the event of a flat tire
Run-flat tires
With a damaged tire, is possible to continue
driving at speeds of up to 50 mph/80 km/h.
When driving with a damaged tire:
1. Avoid sudden braking and steering maneu-
vers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. At the next opportunity, check the inflation
pressure in all four tires.
If the inflation pressure in all four tires is cor-
rect, the Flat Tire Monitor might not have
been initialized. The system must then be
initialized.
Possible driving distance with complete loss of
tire pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the vehi-
cle while driving.
With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damaged tires, the handling
characteristics change, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steering response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.

Since the possible driving distance depends to
a considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
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 while driving can
indicate final failure of the tire. Reduce
your speed and bring the vehicle to a stop; oth-
erwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center.<

Tire Pressure Monitor TPM

The concept
Check the inflation pressure in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.
Functional requirement
The system must have been reset while the
inflation pressure was correct; otherwise, reli-
able signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
System limitations
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
The system does not function correctly if it has
not been reset. For example, a flat tire may be
