A low tire warning light also appears on the instrument
panel cluster when a low tire condition exists. The
DIC message, CHECK TIRE PRESSURE and the low
tire pressure warning light will be shown each time
the engine is started and stay on until the low tire
condition is corrected.
When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is significantly
under-inflated.
You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the vehicle’s tire information placard.
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability. Each tire, including the spare, should be
checked monthly when cold and set to the
recommended inflation pressure as specified in the
vehicle placard and owner’s manual.
The Tire and Loading Information Label (tire information
placard) is either on the rear edge of the driver’s door
or the driver’s door jamb near the latch. This label shows
the size of your vehicle’s original tires and the correct
inflation pressure for your vehicle’s tires when they
are cold. See
Inflation - Tire Pressure on page 5-57.
Your vehicle’s TPM system can alert you about a low or
high tire pressure condition but it does not replace
normal tire maintenance. See
Rotation on page 5-60
Each TPM sensor has a unique identification code that
is matched to one of the four tire positions on your
vehicle. The tire and wheel assembly positions are, left
front (LF); right front (RF); right rear (RR) and left
rear (LR). Any time you rotate your vehicle’s tires or
replace one or more TPM sensors, the identification
codes will need to be matched to the new tire and wheel
position. The TPM matching process is performed in
a specific sequence and time limit. A special tool is also
required. See your dealer for service.
The SVC TIRE MONITOR message is displayed when
the TPM system is malfunctioning. For example,
one or more TPM sensors may be inoperable or
missing. See your dealer for service.
