"Flat Tire Monitor"
Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
TPM takes into account that tire pressures
change while the vehicle is being driven. The
tire pressures do not need to be corrected
unless the TPM instructs you to do so by means
of color indicators.
Green
The tire inflation pressure corresponds to the
established target value.
The status is displayed.
"TPM active" appears on the Control Display.
Tire Pressure Monitor TPM*
One wheel yellow
The concept
There is a flat tire or substantial loss of tire pres-
sure in the indicated tire. A message appears on
the Control Display.
RDC monitors the tire inflation pressure in the
four mounted tires during a trip. The system
notifies you if there is a significant loss of pres-
sure in one or more tires.
All wheels yellow
There is a flat tire or substantial loss of tire pres-
sure in several tires. A message appears on the
Control Display.
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.
Gray
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.
The system cannot detect a puncture.
Possible reasons for this:
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
>
>
TPM is being reset
Temporary malfunction caused by systems
or devices using the same radio frequency
>
Malfunction
System limitations
TPM cannot warn you in advance of sud-
den severe tire damage caused by out-
side influences.<
Resetting the system
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
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.

"Vehicle Info"
"Vehicle status"
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.
