Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to
a receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on
the vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, 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 tirepressure telltale when one or
more of your tires is significantly
under‐inflated.
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 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.
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 under‐inflation
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 one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start‐ups as
long as the malfunction exists.
When the malfunction indicator
is illuminated, the system may
not be able to detect or signal low
tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS to continue to function
properly.

11-4 Service and Maintenance
.Body hinges and latches, key
lock cylinders, hood latch
assemblies, secondary latches,
pivots, spring anchor and
release pawl, hood and door
hinges, rear folding seats,
and liftgate hinges lubrication.
SeeRecommended Fluids
and Lubricants on page 11‑7.
More frequent lubrication may
be required when the vehicle
is exposed to a corrosive
environment. Applying silicone
grease on weatherstrips with a
clean cloth makes them last
longer, seal better, and not
stick or squeak.
.Restraint system component
check. See Safety System
Check on page 3‑31.
.Fuel system inspection for
damage or leaks.
.Exhaust system and nearby heat
shields inspection for loose or
damaged components.
Additional Required Services
Every 12 000 km/7,500 Miles
.Rotate tires. Tires should
be rotated every 12 000 km/
7,500 miles. See Tire Rotation
on page 10‑52.
At Each Fuel Stop
.Engine oil level check.
See Engine Oil on page 10‑8.
.Engine coolant level check.
SeeEngine Coolant on
page 10‑15.
.Windshield washer fluid level
check. See Washer Fluid on
page 10‑23. Once a Month
.Tire inflation check. See
Tire
Pressure on page 10‑45.
.Tire wear inspection. See Tire
Inspection on page 10‑51.
.Sunroof track and seal
inspection, if equipped.

11-6 Service and Maintenance
.Evaporative control system
inspection. Check all fuel and
vapor lines and hoses for proper
hook‐up, routing, and condition.
Check that the purge valve,
if the vehicle has one, works
properly. Replace as needed.
An Emission Control Service.
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.First Engine Oil Change After
Every 160 000 km/100,000 Miles
.Automatic transmission fluid
change (normal service).
See
Automatic Transmission
Fluid on page 10‑13.
.Spark plug replacement and
spark plug wires inspection.
An Emission Control Service.
.All‐wheel drive only:
Transfer case fluid change
(normal service). During any
maintenance, if a power washer
is used to clean mud and dirt
from the underbody, care should
be taken to not directly spray
the transfer case output seals.
High pressure water can
overcome the seals and
contaminate the transfer case
fluid. Contaminated fluid will
decrease the life of the transfer
case and should be replaced. First Engine Oil Change After
Every 240 000 km/150,000 Miles
.Engine cooling system drain,
flush, and refill (or every five
years, whichever occurs first).
See
Cooling System on
page 10‑15. An Emission
Control Service.
.Engine drive belts inspection
for fraying, excessive cracks,
or obvious damage (or every
10 years, whichever occurs
first). Replace, if needed.
