In Brief 1-19
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The Tire Pressure Monitor System
alerts you when a significant
reduction in pressure occurs in one
or more of your vehicle’s tires by
illuminating the low tire pressure
warning light on the instrument
cluster. The warning light will remain
on until the tire pressure is
corrected. The proper tire pressures
for your vehicle are listed on the
Tire and Loading Information label
located on the driver side center
pillar (B pillar). SeeVehicle Load
Limits on page 9‑10.
You may notice during cooler
conditions that the low tire pressure
warning light will appear when the vehicle is first started and then turn
off as you drive. This may be an
early indicator that your tire
pressures are getting low and the
tires need to be inflated to the
proper pressure.
Note:
The Tire Pressure Monitor
System can alert you about low tire
pressure, but it does not replace
normal monthly tire maintenance.
It is the driver ’s responsibility to
maintain correct tire pressures.
See Tire Pressure Monitor System
on page 10‑44andTire Pressure
Monitor Operation on page 10‑45.
Tire Sealant and
Compressor Kit
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. The kit can be used
to seal small punctures in the tread
area of the tire.
See Tire Sealant and Compressor
Kit
on page 10‑58for complete
operating information.

Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See
Airbag Readiness Light
on
page 5‑14for more information.
Notice: If an airbag covering is
damaged, opened, or broken, the
airbag may not work properly. Do
not open or break the airbag
coverings. If there are any
opened or broken airbag covers,
have the airbag covering and/or
airbag module replaced. For the
location of the airbag modules,
see What Makes an Airbag
Inflate?
on page 3‑35. See your
dealer/retailer for service.
Replacing Airbag System
Parts After a Crash
{WARNING
A crash can damage the airbag
systems in your vehicle.
A damaged airbag system may
not work properly and may not
protect you and your
passenger(s) in a crash, resulting
in serious injury or even death. To
help make sure your airbag
systems are working properly
after a crash, have them
inspected and any necessary
replacements made as soon as
possible. If an airbag inflates, you will need to
replace airbag system parts. See
your dealer/retailer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light
on
page 5‑14for more information.

Instruments and Controls 5-17
If the check engine light comes on
and stays on, while the engine is
running, this indicates that there is
an OBD II problem and service is
required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle's fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.
Notice: Modifications made to the
engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to
costly repairs not covered by the
vehicle warranty. This could also
result in a failure to pass a
required Emission Inspection/
Maintenance test. See
Accessories and Modifications
on
page 10‑3.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.
If the light continues to flash, when
it is safe to do so, stop the vehicle.
Find a safe place to park the
vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer/retailer for service as
soon as possible.
Light On Steady: An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
An emission system malfunction
might be corrected.
.Make sure the fuel cap is fully
installed. See Filling the Tankon
page 9‑42. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.

5-18 Instruments and Controls
A few driving trips with the cap
properly installed should turn the
light off.
.If the vehicle has been driven
through a deep puddle of water,
the vehicle's electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out. A few
driving trips should turn the
light off.
.Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these
conditions occurs, change the
fuel brand used. It will require at
least one full tank of the proper
fuel to turn the light off.See
Gasoline Specifications
on
page 9‑40.
If none of the above have made the
light turn off, your dealer/retailer can
check the vehicle. The dealer/
retailer has the proper test
equipment and diagnostic tools to
fix any mechanical or electrical
problems that might have
developed.
Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection could
prevent getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
.The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in ON/
RUN and the light is not on.
.The vehicle will not pass this
inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would be
considered not ready for
inspection. This can happen if
the battery has recently been
replaced or if the battery has run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer/
retailer can prepare the vehicle
for inspection.
