Tire Pressure Monitoring System (TPMS)*
Problem Possible causes/consequences and
M Solutionsh
The yellow
combination
low tire
pressure/TPMS
malfunction
telltale
illuminates
continuously. The TPMS detects a loss of pressure in at least one tire.
X
Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. Observe the traffic
situation around you.
X Check and correct tire inflation pressure as required
(Y page 126).
If the tire inflation pressure in the respective tire(s) has
(have) been corrected, the combination low tire pressure/TPMS
malfunction telltale goes out after a few minutes of driving.
See also “Restarting the TPMS” (Y page 129). h
The

malfunction
telltale flashes
60 seconds and
then stays
illuminated. There is a malfunction in the TPMS.
X
Have the TPMS checked at an authorized smart center.
After the malfunction has been remedied the combination low
tire pressure/TPMS malfunction telltale goes out after a few
minutes of driving. G
WARNING
Each tire should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the Tire and Loading Information placard. If
your vehicle has tires of a different size than the size indicated on the Tire and Loading
Information placard, you should determine the proper tire inflation pressure for those
tires.
As
an added safety feature, your 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 significantly underinflated.
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
underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability. Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even
if underinflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS malfunction indicator is combined with the 172
