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.
Resetting the system
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.

automatically as you drive. The indicator lamp
goes out after the system reset is completed.
You can stop driving at any time. The resetting
continues automatically when you resume driv-
ing.
