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.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System

Seats and Restraints 3-43
Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto or change about the vehicle
that could keep the airbags
from working properly?
A: Yes. If you add things that
change the vehicle's frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Changing or
moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,
steering wheel, instrument
panel, roof-rail airbag modules,
ceiling headliner or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
rollover sensor module, or airbag
wiring can affect the operation of
the airbag system.
In addition, the vehicle has a
passenger sensing system for
the right front passenger
position, which includes sensors that are part of the passenger
seat. The passenger sensing
system may not operate properly
if the original seat trim is
replaced with non-GM covers,
upholstery or trim, or with GM
covers, upholstery or trim
designed for a different vehicle.
Any object, such as an
aftermarket seat heater or a
comfort enhancing pad or
device, installed under or on top
of the seat fabric, could also
interfere with the operation of
the passenger sensing system.
This could either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system from
properly turning off the
passenger airbag(s). See
Passenger Sensing System
on
page 3‑38.
If you have questions, call
Customer Assistance. The
phone numbers and addresses
for Customer Assistance are in Step Two of the Customer
Satisfaction Procedure in this
manual.
If the vehicle has rollover
roof-rail airbags, see
Different
Size Tires and Wheels
on
page 10‑53for additional
important information.
Q: Because I have a disability, I have to get my vehicle
modified. How can I find out
whether this will affect my
airbag system?
A: If you have questions, call
Customer Assistance. The
phone numbers and addresses
for Customer Assistance are in
Step Two of the Customer
Satisfaction Procedure in this
manual.
In addition, your dealer/retailer and
the service manual have information
about the location of the airbag
sensors, sensing and diagnostic
module and airbag wiring.

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.

Instruments and Controls 5-21
Tire Pressure Light
For vehicles with a tire pressure
monitoring system, this light comes
on briefly when the engine is
started. It provides information
about tire pressures and the Tire
Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A tire pressure message in the
Driver Information Center (DIC), can
accompany the light. SeeTire
Messages
on page 5‑41for more
information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the tire loading information label. See
Tire
Pressure
on page 10‑43for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
See Tire Pressure Monitor
Operation
on page 10‑45for more
information.
Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced. Notice:
Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
The oil pressure light should come
on briefly as the engine is started.
If it does not come on have the
vehicle serviced by your dealer/
retailer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
