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.

<

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.

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.

The tire inflation pressure corresponds to the 
established target value.
"TPM active" appears on the Control Display.

There is a flat tire or substantial loss of tire pres-
sure in the indicated tire. A message appears on 
the Control Display.

There is a flat tire or substantial loss of tire pres-
sure in several tires. A message appears on the 
Control Display.

The system cannot detect a puncture.
Possible reasons for this:

>

TPM is being reset

>

Temporary malfunction caused by systems 
or devices using the same radio frequency

>

Malfunction

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

changed, reset the system.

"Vehicle status"

3.

"Reset TPM"

4.

Start the engine - do not drive away.

5.

Start the initialization using "Reset TPM".

6.

Start to drive.
The tires are shown in gray and "Resetting 
TPM..." is displayed.

After driving a few minutes, the set inflation 
pressures in the tires are accepted as the target 
values to be monitored. The system reset is 
completed during your drive, and can be inter-
rupted at any time. When driving resumes, the 
reset is continued automatically. On the Control 
Display, the tires are shown in green and 
"Status: TPM active" is displayed again.
