Temperature Control:For dual zone, turn the
thumbwheels up or down to increase or decrease
the temperature on the driver or the passenger side
of the vehicle. For single zone, turn the knob clockwise
or counterclockwise to increase or decrease the
temperature.

(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:
H
(Vent):Air is directed to the instrument panel
outlets.
)
(Bi-Level):Air is divided between the instrument
panel outlets and the floor outlets. Single Zone

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.

Engine OilChecking Engine OilIt is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 6-14
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

How to Reset the Engine Oil Life
SystemThe Engine Oil Life System calculates when to change
the engine oil and filter based on vehicle use. Whenever
the oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where the oil is changed prior to a CHANGE ENGINE OIL
SOON message being turned on, reset the system.
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Engine
Oil Life System:
1. 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%.
If the CHANGE ENGINE OIL SOON message comes
back on when the vehicle is started, the Engine Oil Life
System has not reset. Repeat the procedure.
What to Do with Used OilUsed engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Recycle it by taking it to a
place that collects used oil.Engine Air Cleaner/FilterThe engine air cleaner/filter is located in the engine
compartment on the driver’s side of the vehicle.
SeeEngine Compartment Overview on page 6-14for
more information on location.

When to Inspect the Engine Air
Cleaner/FilterInspect the air cleaner/filter at the MaintenanceII
intervals and replace it at the first oil change after each
50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 7-3for more information. If you
are driving in dusty/dirty conditions, inspect the filter
at each engine oil change.How to Inspect the Engine Air
Cleaner/FilterTo inspect the air cleaner/filter, remove the filter from
the vehicle and lightly shake the filter to release
loose dust and dirt. If the filter remains caked with dirt, a
new filter is required.To inspect or replace the engine air cleaner/filter do the
following:
1. Lift the filter cover tabs on top of the engine air
cleaner/filter housing.6-20
