x9w(Fan):Press the button with the fan symbol
to manually increase or decrease the fan speed.
Keep pressing the up or down arrow on this switch until
the desired fan speed appears on the display.
Pressing the arrows will delete AUTO from the digital
display. The fan graphics with the fan speed bars will be
shown. To increase the fan speed so that more air
ows into the vehicle, press the up arrow on the
fan switch. To decrease the fan speed and airow,
press the down arrow. The AUTO button must be
pressed to return to the automatic fan control.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter
may need to be replaced. For more information,
seePassenger Compartment Air Filter on page 3-32
andScheduled Maintenance on page 6-4.
?(Recirculation):Press this button to turn the
recirculation mode on or off. When the climate control
system is in recirculation mode an indicator light will
come on. This mode prevents outside air from entering
your vehicle. It can be used to prevent outside air and
odors from entering your vehicle and to help cool the air
inside your vehicle more quickly. Recirculation mode is
not available in defrost or defog mode.
^(Air Conditioning Off):Press this button to turn the
air conditioning compressor off. Press AUTO to return
to automatic operation. When in AUTO, the air
conditioning compressor will come on automatically,
as needed.
Air conditioning does not operate at temperatures below
about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be turned
off in defrost and defog, as it helps to remove moisture
from the vehicle. It also helps to keep the windows clear.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.

Outlet Adjustment
Use the tab located on the air outlets to change the
direction of the airow.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter removes certain
particles from the air including pollen and dust particles.
Reductions in airow, which may occur more often in
dusty areas, indicate that the lter may need to be
replaced. SeeScheduled Maintenance on page 6-4for
information on how often to replace the lter.
Notice:Driving without a passenger compartment
air lter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the old
lter with a new one.
The passenger compartment air lter is located on the
passenger side of the engine compartment near the
battery. SeeEngine Compartment Overview on
page 5-14.

Checking Engine Oil (Except Z06)
If the CHECK OIL LEVEL message on the Driver
Information Center (DIC) comes on, check the engine
oil level right away. For more information, seeDriver
Information Center (DIC) on page 3-51. You should
check the engine oil level regularly; this is an added
reminder.
It is a good idea to check the engine oil level every time
you get fuel. 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 5-14
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a lint-free
paper towel or a cloth, then push it back in all
the way.
3. Remove the dipstick again, keeping the tip down
and read the level on the cross-hatched area. Oil
levels that fall in the cross-hatched area are normal.
4. Push the dipstick back in all the way.
5-17

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-14for
the location of the engine air cleaner/lters.
Notice:If you spray water into the engine air
cleaner/lter intake and water enters the engine
air cleaner/lter housing, you could damage
your vehicle’s engine. The repairs would not be
covered by your warranty. Do not spray water
into the engine air cleaner/lter intake and/or
housing.
If you are cleaning your vehicle with the hood open,
take care not to spray water directly near the lter
opening of the air cleaner, as shown in the illustration,
as this could damage your vehicle’s engine.
When to Inspect the Engine Air
Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace them at the rst oil change after
each 50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 6-4for more information.
If you are driving in dusty/dirty conditions, inspect the
lters at each engine oil change.
5-25

How to Inspect the Engine Air
Cleaner/Filters
To inspect the air cleaner/lters, remove the lters from
the vehicle and lightly shake the lters to release
loose dust and dirt. If the lters remain caked with dirt,
new lters are required.
To inspect or replace the engine air cleaner/lters,
do the following:
1. Remove the screws holding the lter element in
place.
2. Pull on latches found on either side of the lter.3. Inspect or replace the lter. SeeMaintenance
Replacement Parts on page 6-14.
4. Reverse Steps 1 and 2 to replace the air
cleaner/lter cover.
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned. The
air cleaner not only cleans the air; it helps to
stop ames if the engine backres. If it is not
there and the engine backres, you could be
burned. Do not drive with it off, and be careful
working on the engine with the air cleaner/
lter off.
Notice:If the air cleaner/lter is off, a backre
can cause a damaging engine re. And, dirt can
easily get into your engine, which will damage
it. Always have the air cleaner/lter in place when
you are driving.
