Tire Pressure Monitor System
The Tire Pressure Monitor (TPM) System on your vehicle,
uses radio and sensor technology to check tire pressure
levels. Sensors, mounted on each tire and wheel
assembly transmit tire pressure readings to a receiver
located in the vehicle. The TPM sensors transmit tire
pressure readings once every 60 seconds while the
vehicle is being driven and once every 60 minutes when
the vehicle is stationary for more than 15 minutes. Using
the Driver Information Center (DIC), tire pressure levels
can be viewed by the driver. The TPM system also uses
the DIC to warn the driver when air pressure, in one or
more tires, falls below 25 psi (172 kPa) or is above
42 psi (290 kPa). For additional information and details
about the DIC operation and displays seeDIC Controls
and Displays on page 3-61andDIC Warnings and
Messages on page 3-64.
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 signicantly
under-inated.
You should stop and check your tires as soon as
possible, and inate them to the proper pressure as
indicated on the vehicle’s tire information placard.
Driving on a signicantly under-inated tire causes the
tire to overheat and can lead to tire failure. Under-ination
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 ination pressure
as specied in the vehicle placard and owner’s manual.
The Tire and Loading Information Label (tire information
placard) is on the rear edge of the driver’s door, below the
door latch. This label shows the size of your vehicle’s
original tires and the correct ination pressure for your
vehicle’s tires when they are cold. SeeLoading Your
Vehicle on page 5-30.
Your vehicle’s TPM system can alert you about a low or
high tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 6-57

Maintenance Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
(a)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the uid level checked. Add uid if needed.
(b)Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(c)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
(The airbag system does not need regular maintenance.)(d)Lubricate the trunk key lock cylinder. Lubricate all
body door hinges. Lubricate all hinges and latches,
including those for the hood, trunk, console door and
any folding seat hardware. More frequent lubrication
may be required when exposed to a corrosive
environment. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal
better and not stick or squeak.
(e)If you drive regularly under dusty conditions, the
lter may require replacement more often.
(f)Change automatic transmission uid and lter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
Uses such as high performance operation.
(g)Drain, ush and rell cooling system. See Engine
Coolant on page 6-20for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ller neck.
Pressure test the cooling system and pressure cap.
(h)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.
