System limits
TPM cannot warn you of sudden serious
tire damage caused by external influ-
ences. <
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.
If a wheel without TPM electronics has been
mounted or if the TPM experiences temporary
interference from other systems or devices that
use the same radio frequency, then the system
is inactive and unable to report a flat tire.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes into account the fact that the tire
pressure changes during driving. A correction is
only required if the color of the TPM display
indicates that it is necessary.
Green
The tire pressure matches the learned set state.
"Status: TPM active" appears on the Control
Display.
One wheel is yellow
There is a flat tire or a major drop in inflation
pressure in the indicated tire. A message
appears on the Control Display.
All wheels are yellow
There is a flat tire or a major drop in inflation
pressure in several tires. A message appears on
the Control Display.
Gray
The system cannot detect a flat tire.
Reasons for this can include:
> TPM is in the process of being reset
> Temporary interference due to systems or
devices that use the same radio frequency
> Malfunction
Resetting system
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change. <
The reset process is completed during driving
and can be interrupted at any time. When driv-
ing resumes, the process resumes automati-
cally.
