Tire Pressure Monitor Tpm - BMW 323i Owner's Manual

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.<

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 has to have been reset at the cor-
rect inflation pressure; otherwise, a reliable
reporting of a flat tire is not assured.
Always use wheels with TPM electronics to
assure a trouble-free function of the system.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
It is impossible to provide advance warn-
ing of sudden, severe tire damage caused
by outside influences.<
The system does not function correctly if it
has not been reset. For example, a flat tire may
be indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:
> when a wheel without TPM electronics is
installed.
> when other systems or devices that use the
same radio frequency interfere with TPM.
