Operation
Checking tire inflation pressure elec-
tronically with the Tire Pressure Moni-
toring System (TPMS) (vehicles without
steering wheel buttons)
i USA only:
The Tire Pressure Monitoring System (TPMS) is
equipped with a combination low tire pressure/
TPMS h malfunction indicator lamp in the in-
strument cluster. Depending on how the indica-
tor lamp comes on, it indicates a low tire
pressure condition or a malfunction in the TPMS
system itself:
O If the indicator lamp remains lit, one or more
of your tires is significantly underinflated.
There is no malfunction in the TPMS.
O If the indicator lamp flashes for 60 seconds
and then remains lit, the TPMS system itself
is not operating properly.
i Canada only:
The Tire Pressure Monitoring System (TPMS) is
equipped with a h low tire pressure indicator
lamp in the instrument cluster. If the indicator
lamp comes on illuminates, one or more of your
tires is significantly underinflated.
The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, 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 warn you against incor-
rectly selected tire inflation pressure and
does not warn you when the tire pressures is
not properly selected for the respective vehi-
cle load. It warns you only when the pressure
of one or more tires decreases significantly
below the reference inflation pressure which
was stored at the time of calibration of the
TPMS after you inflated the tires.
Always make sure that you recalibrate the
TPMS after you have inflated the tires to the
recommended cold inflation pressure.
Always adjust tire inflation pressure accord-
ing to the tire and loading information label
on the driver's door B-pillar.
Underinflated tires wear excessively and/or
unevenly, adversely affect handling and fuel
economy, and are more likely to fail from be-
ing overheated.
Overinflated tires can adversely affect han-
dling and ride comfort, wear unevenly, in-
crease stopping distance, and result in
sudden deflation (blowout) because they are
more likely to become punctured or damaged
by road debris, potholes, etc.
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 care-
fully applying the brakes and avoiding abrupt
steering maneuvers.
G Warning
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the recommended inflation pressure
on the tire and loading information label. (If
your vehicle has tires of a different size than
the size indicated on the vehicle label or the
tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for
those tires).
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a h
low tire pressure indicator lamp when one or
more of your tires is significantly underin-
flated. Accordingly, when the h low tire
pressure indicator lamp illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. 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 vehi-
cle's handling and stopping ability.
