Tire Pressure Monitoring System
(TPMS)
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS). It measures the
tire inflation pressure in the vehicle's tires
and issues warnings in case of pressure loss.
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:
If the telltale illuminates continuously, one
R
or more of your tires are significantly
underinflated. There is no malfunction in
the TPMS.
If the telltale flashes for 60 seconds and
R
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.
It monitors the tire inflation pressure, as
selected by the driver, in all four tires. A
warning is issued to alert you to a decrease
in pressure in one or more of the tires.

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 or, if available, on the
supplemental tire inflation pressure
information on the inside of the fuel filler
flap.
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, including the spare (if provided),
should be checked every other week when
cold and inflated to the inflation pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver's door B-pillar or, if available,
the tire inflation pressure label on the inside
of the fuel filler flap. If your vehicle has tires
of a different size than the size indicated on
the Tire and Loading Information placard or,
if available, the tire inflation pressure label,
Operation
Tires and wheels
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 are 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
