achieve the recommended tire inflation
pressure.
X If you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.
X
Install the valve cap.
X Repeat this procedure for each tire.
Tire Pressure Monitoring System (TPMS)*
Your vehicle may be equipped with a Tire
Pressure Monitoring System (TPMS).
It monitors the tire inflation pressure in
all four tires. A warning is issued to alert
you to a decrease in pressure in one or more
of the tires.
The Tire Pressure Monitoring System
(TPMS) is equipped with a combination low
tire pressure/TPMS malfunction telltale in
the instrument cluster. Depending on how
the telltale illuminates, it indicates a low
tire pressure condition or a malfunction in
the TPMS system itself:
R
If the telltale illuminates continuously,
one or more of your tires is significantly
underinflated. There is no malfunction
in the TPMS.
R
If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly.
The TPMS only functions on wheels that are
equipped with the proper electronic
sensors.
G
WARNING
The TPMS does not indicate a warning for
wrongly selected inflation pressures.
Always adjust tire inflation pressure
according to the Tire and Loading
Information placard on the driver’s door
B‑pillar.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by
carefully applying the brakes and avoiding
abrupt steering maneuvers.
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 increases energy
consumption, reduces 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 low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately 1 minute and then remain
continuously illuminated.
