on the
instrument panel to turn off traction control.
F
illuminates and the appropriate DIC message
displays. SeeDIC Warnings and Messages
on page 4-44.
•

Tire Pressure MonitorThis vehicle may have a Tire Pressure Monitor
System (TPMS).
The Tire Pressure Monitor
alerts you when a
significant reduction in
pressure occurs in one or
more of the 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).
SeeLoading the Vehicle on page 5-20.
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 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.
SeeTire Pressure Monitor System on page 6-60and
Tire Pressure Monitor Operation on page 6-62.
Engine Oil Life SystemThe engine oil life system calculates engine oil life
based on vehicle use and displays a DIC message
when it is necessary 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 System1. Display the OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the DIC
for more than five seconds. The oil life will change
to 100%.
SeeEngine Oil Life System on page 6-18.Fuel E85 (85% Ethanol)If the vehicle has the 3.5L V6 engine (VIN Code K)
or the 3.9L V6 engine (VIN Code M), you can use either
unleaded gasoline or ethanol fuel containing up to
85% ethanol (E85). SeeFuel on page 6-5. In all other
engines, use only the unleaded gasoline described
underGasoline Octane on page 6-6.
Vehicles that have the 3.5L V6 engine (VIN Code K) or
the 3.9L V6 engine (VIN Code M) have a yellow fuel
cap and can use 85% ethanol fuel (E85). SeeFuel E85
(85% Ethanol) on page 6-8.

Restraint System CheckChecking the Restraint SystemsSafety BeltsNow and then, check that the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing
its job. See your dealer/retailer to have it repaired. Torn
or frayed safety belts may not protect you in a crash.
They can rip apart under impact forces. If a belt is torn
or frayed, get a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 4-23for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 6-90.
AirbagsThe airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 4-24for 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, seeWhat
Makes an Airbag Inflate? on page 2-63. See
your dealer/retailer for service.

(Fan Control):Turn clockwise or counterclockwise to
increase or decrease the fan speed. Positioning the knob
between two modes, can select a combination of those
modes.
If the airflow seems low when the fan is at the highest
setting, the passenger compartment air filter may need to
be replaced. There will be some airflow noticeable from
the various outlets when driving, even with the fan in
the off position. For more information, seePassenger
Compartment Air Filter on page 4-20andScheduled
Maintenance on page 7-3.
Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the direction of the airflow
inside the vehicle.
To change the current mode, select one of the following:

4-17

Outlet AdjustmentUse the thumbwheel located below or to the side of the
outlet, to change the direction of the air flow.Operation Tips•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into the vehicle.
•
Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•
Keep the path under the front seats clear of objects
to help circulate the air inside the vehicle more
effectively.
•
If the airflow seems low when the fan is at the
highest setting, the passenger compartment
air filter, if equipped, may need to replaced.
For more information, seePassenger Compartment
Air Filter on page 4-20andScheduled Maintenance
on page 7-3.
•
If fogging reoccurs while in vent or bi-level modes
with mild temperature throughout the vehicle, turn
on the air conditioner to reduce windshield fogging.
Passenger Compartment Air FilterThe vehicle has a passenger compartment particulate
air filter. It is located in the engine compartment,
below the air inlet grille on the passenger side.
The filter traps most of the pollen from air entering
the climate control system. It needs to be changed
periodically to ensure system performance. For
information on how often to change the passenger
compartment air filter, seeScheduled Maintenance
on page 7-3.
To change the passenger compartment air filter:
1. Turn off the ignition when the windshield wipers are
in the up position.
2. Raise the vehicle hood.
3. Pull back the hood weatherstrip from the
passengers side of the vehicle halfway to center.

4. Remove the air inlet grille retainers.
5. Lift the air inlet grille and disconnect the washer
hose at the quick-connect.
6. Remove the air inlet grille.
7. Remove the water deflector plate.
8. Remove the old passenger compartment air filter.
9. Reverse the steps to install the new air filter.
For best climate control system performance, reinstall
the air filter.
For the type of filter to use, seeMaintenance
Replacement Parts on page 7-11.
Warning Lights, Gages, and
IndicatorsWarning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gages could prevent injury.
Warning lights come on when there might be or there
is a problem with one of the vehicle’s functions. Some
warning lights come on briefly when the engine is started
to indicate they are working.
Gages can indicate when there might be or there is a
problem with one of the vehicle’s functions. Often gages
and warning lights work together to indicate a problem
with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
could be a problem, check the section that explains
what to do. Follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
