Functional requirement

In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.

Each time a tire inflation pressure has
been corrected or a wheel or tire has been

changed, reset the system.

System limitations

TPM cannot warn you in advance of sud-
den severe tire damage caused by out-

side influences.

The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics, such as
a compact spare wheel, has been mounted, or if
TPM is temporarily malfunctioning due to other
systems or devices using the same radio fre-
quency.

Resetting the system

Each time a tire inflation pressure has
been corrected or a wheel or tire has been

changed, reset the system.

matically. The indicator lamp goes out after
the system reset is completed.
