When your vehicle is ®rst started, the display will show
the driver's temperature setting, the fan speed and
the air delivery mode.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
will show readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between them.
Manual Operation
SMODET:Pressing the MODE switch and changing
the mode cancels automatic operation and places the
system in manual mode. Press AUTO to return to
automatic operation.
To change the current mode, select one of the following:
G(Vent):This mode directs air to the instrument
panel outlets.
+(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the ¯oor outlets.
Some air may be directed toward the windshield.
In automatic operation, cooler air is directed to the upper
outlets and warmer air to the ¯oor outlets.
8(Floor):This mode directs most of the air to the
¯oor outlets with some air directed to the outboard
outlets (for the side windows) a little air directed to the
windshield.
The MODE switch can also be used to select the
¯oor/defog mode. Information on defogging and
defrosting can be found later in this section.
y9z(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the air¯ow seems low when the fan speed is at
the highest setting, the passenger compartment air ®lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-35andPart A: Scheduled Maintenance Services on
page 6-4.
?(Recirculation):This mode keeps outside air
from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. When the button is pressed, an indicator
light will come on. The air-conditioning compressor also
comes on.
3-29

Outlet Adjustment
Use the levers located in the center of each outlet to
change the direction of the air¯ow. Use the thumbwheels
to open or close the outlets.
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 de¯ectors may
adversely affect the performance of the system.
·Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
·If the air¯ow seems low when the fan speed is at
the highest setting, the passenger compartment
air ®lter may need to be replaced. For more
information, see
Passenger Compartment Air Filter
on page 3-35andPart A: Scheduled Maintenance
Services on page 6-4.
3-33

Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment ®lter. The ®lter removes certain
contaminants from the air, including pollen and
dust particles.
The ®lter is located inside the air control module, with
an access panel under the instrument panel near
the accelerator pedal.
Reductions in air¯ow, which may occur more quickly in
dusty areas, indicate that the ®lter needs to be
replaced. The ®lter also should be replaced as part of
routine scheduled maintenance. See
Part A: ScheduledMaintenance Services on page 6-4
for replacement
intervals. See your dealer for assistance when changing
the ®lter.
Your vehicle will not be damaged if you choose not to
replace the ®lter once the old one is removed.
Steering Wheel Climate Controls
You can adjust the temperature using the steering wheel
controls.
The control for the
temperature is located on
the left side of the
steering wheel.
yTEMPz(Temperature):Press the up or down
arrow on this control to increase or decrease the
temperature.

Engine Oil
If the CHECK OIL LEVEL message appears on the
instrument cluster, it means you need to check
your engine oil level right away. For more information,
see ªCHECK OIL LEVELº under
DIC Warnings and
Messages on page 3-56.
You should check your engine oil level regularly; this is
an added reminder.
5-13

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-12for
location of the engine air cleaner/®lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/®lter every 15,000 miles
(25 000 km) and replace every 30,000 (50 000 km). If
you are driving in dusty/dirty conditions, inspect the ®lter
at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/®lter, remove the ®lter from
the vehicle and lightly shake the ®lter to release
loose dust and dirt. If the ®lter remains caked with dirt, a
new ®lter is required.
To inspect or replace the ®lter, do the following:
1. Loosen the air duct
clamp, which is located
at the mass air¯ow
sensor end of the
air duct.
2. Disconnect the air duct from the mass
air¯ow sensor.
