Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of a tire.
Reduce speed and stop; otherwise, pieces
of the tire could come loose and cause an
accident.
Do not continue driving. Contact an author-
ized service center or another qualified
service center or repair shop.
System limits
Temperature
The tire inflation pressure depends on the
tire's temperature.
Driving or exposure to the sun will increase
the tire temperature, thus increasing the
tire inflation pressure.
The tire inflation pressure is reduced when
the tire temperature falls again.
These circumstances may cause a warning
when temperatures fall very sharply.
Sudden tire pressure loss
The system cannot indicate sudden serious
tire damage caused by external circumstan-
ces.
Failure performing a reset
The system does not function properly if a
reset has not been carried out, for instance
a flat tire is reported though tire inflation
pressures are correct.
Malfunction
The yellow warning light flashes and
is then illuminated continuously. A
Check Control message is displayed.
It may not be possible to identify tire pres-
sure losses.
Examples and recommendations in the fol-
lowing situations:

Safety
–
Wheel without TPM wheel electronics is
mounted: Have it checked by an author-
ized service center or another qualified
service center or repair shop as needed.
–
Malfunction: have the vehicle checked
by an authorized service center or an-
other qualified service center or repair
shop.
–
The system was unable to complete the
reset. Perform a system reset again.
–
Fault caused by systems or devices with
the same radio frequency: after leaving
the area of the interference, the system
automatically becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la-
bel. (If the vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.) As an added safety
feature, the vehicle has been equipped with
a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale
when one or more of your tires is signif-
icantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates,
you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-in-
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han-
dling and stopping ability. Please note that
the TPMS is not a substitute for proper tire
maintenance, and it is the driver's responsi-
bility to maintain correct tire pressure, even
