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 the vehicle.
Use of non-GM approved hood deectors 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 the vehicle more
effectively.
This vehicle has a passenger compartment air lter.
If the airow seems low when the fan is at the highest
setting it may need to be replaced. For more
information, seePassenger Compartment Air
Filter on page 3-29.
Passenger Compartment Air Filter
The passenger compartment air lter is located in
the engine compartment below the air inlet grille,
near the passenger’s side windshield wiper arm.
SeeEngine Compartment Overview on page 5-12.
The lter traps most of the pollen from the air entering
the air conditioning module. The lter needs to be
changed periodically to keep the air conditioning working
at its best. For information on how often to change the
passenger compartment air lter, seeScheduled
Maintenance on page 6-4.To change the passenger compartment air lter, use the
following steps:
1. Turn the ignition to ACC/ACCESSORY and turn the
windshield wipers on.
2. Turn the ignition to LOCK/OFF when the windshield
wipers are in the upright position.
3. Raise the hood.
4. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
5. Peel back the hood weather-strip from the
passenger’s side of the vehicle halfway to the
center of the hood.
6. Remove the three air inlet grille retainers.
7. Remove the air inlet grille.
8. Remove the water deector panel.

When the ignition is on, the brake system warning
light will also come on when you set your parking brake.
The light will stay on if your parking brake does not
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while you are driving, a chime will
sound and you should pull off the road and stop carefully.
You may notice that the pedal is harder to push. Or, the
pedal may go closer to the oor. It may take longer to
stop. If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-26.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
Antilock Brake System (ABS)
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when
the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the
light comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-35.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-56for
all brake related DIC messages.

There is also a retroactive trip odometer function that
performs the following for each trip odometer:
If the vehicle’s speed has exceeded 3 mph (5 km/h)
during the current ignition cycle, this function will
set the trip odometer to the distance driven
during the current ignition cycle.
If the vehicle’s speed has not exceeded 3 mph
(5 km/h), this function will set the trip odometer
to the distance driven during the previous ignition
cycle plus the distance driven during the current
ignition cycle.
Press and hold the set/reset button on vehicles with
the uplevel DIC or the trip/odometer button on vehicles
with the base level DIC for three seconds, then release
the button. The retroactive trip odometer value will be set
into the currently displayed trip odometer.
Time Elapsed (Uplevel Only)
Press the trip/odometer button until TIME ELAPSED :00
displays. This mode is like a stopwatch, in that you can
clock the time it takes to get from one point to another.
Each of the elds for the hours, minutes, and seconds
are two numeric digits.Once TIME ELAPSED :00 is displayed, press the
set/reset button on vehicles with the uplevel DIC to start
the timing feature. Press the set/reset button again to
stop it. If you will be starting and stopping your vehicle,
during a trip for instance, the TIME ELAPSED feature will
automatically start timing where it left off when you last
stopped. To reset it, press and hold the set/reset button
for about 1.5 seconds. The display will return to zero.
Press the trip/odometer button to exit from the TIME
ELAPSED display.
Average Speed (Uplevel Only)
Press the trip/odometer button until AVERAGE SPEED
displays. This mode shows the average speed of the
vehicle in miles per hour (mph) or kilometers per hour
(km/h). This average is calculated based on the various
vehicle speed recorded since the last reset of this value.
To reset the value, press the trip/odometer button to
display AVERAGE SPEED, then press and hold the
set/reset button on vehicles with the uplevel DIC.
The display will return to zero.
