Outlet Adjustment
Turn the air outlets, located in the middle and at
each outboard side of the instrument panel,
to adjust 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 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.
If the airow seems low when the fan is at the
highest setting, the passenger compartment
air lter may need to be replaced. See
“Passenger Compartment Air Filter” following,
for more information.
Passenger Compartment Air Filter
The passenger compartment air lter is located
near the passenger’s side windshield wiper
arm, under the inlet grille.
The lter traps most of the pollen from entering
the climate control system. Similar to the engine’s
air lter, it may need to be changed periodically
to insure system performance. SeeScheduled
Maintenance on page 473for more information.
To change the passenger compartment air
lter, do the following:
1. Turn the ignition to ACC and the windshield
wipers on.
2. Turn the ignition to 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 the air inlet grille.
5. Remove the hood weather-strip from the
passenger’s side of the vehicle, peeling it
back halfway.

Oil Pressure Light
If there is a problem
with the vehicle’s oil
pressure, this light may
stay on when the
engine is started.
It may also come on while the vehicle is being
driven. This indicates that the engine could be low
on oil or could have some other oil problem.
Have it xed right away.
The oil light could also come on in two other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to
indicate it is working. The light will go out when
the ignition is turned to RUN. If it does not come
on while the ignition is in the on position, there
may be a problem with the fuse or bulb. See
Fuses and Circuit Breakers on page 460.
If the brakes are applied quickly and the vehicle
makes a hard stop, the light may come on for a
moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

CHANGE OIL SOON
This symbol comes on
with this message.
This message displays when service is required
for the vehicle. See your dealer. SeeEngine Oil on
page 350andScheduled Maintenance on
page 473for more information.
The CHANGE OIL SOON message is reset by
acknowledging the message. The ENGINE OIL
MONITOR SYSTEM screen under the options
menu on the DIC must also be reset. See “Engine
Oil Monitor System” in options underDIC Controls
and Displays (Base Level DIC) on page 186orDIC
Controls and Displays (Uplevel DIC with Trip
Computer) on page 190for more information.
This message displays while the ignition is in RUN.
Press the set/reset button to acknowledge this
message and to clear it from the screen.This message continues to display for
three seconds if it has not been acknowledged
when the engine is turned off. It also re-displays
for three seconds if the message has been
acknowledged, but the condition still exists when
the engine is turned off.
If the condition still exists, the message re-appears
when the engine is turned on.
CHARGING SYSTEM FAILURE
This symbol comes on
with this message.
This message displays when there is a problem
with the generator and battery charging systems.
Driving with this problem could drain the battery.

When You Are Ready to Leave After
Parking on a Hill
1. Apply the regular brakes and hold the pedal
down while you:
Start the engine
Shift into a gear
Release the parking brake
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the
chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
The vehicle will need service more often when it
pulls a trailer. SeeScheduled Maintenance
on page 473for more information. Things that are
especially important in trailer operation are
automatic transaxle uid, which should not be
overlled, engine oil, drive belts, cooling,
and brake systems. Each of these is covered in
this manual, and the Index will help locate
them quickly. If trailering, it is a good idea to
review this information before starting on a trip.
Check periodically to see that all hitch nuts
and bolts are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat
during severe operating conditions. SeeEngine
Overheating on page 364.

Supercharger Oil
Because they are technically qualied and have
the proper tools, you should have your dealer
perform this maintenance.
When to Check
SeeAdditional Required Services on page 476for
when the oil level should be checked.
What Kind of Oil to Use
Use only the recommended supercharger oil. See
Recommended Fluids and Lubricants on
page 483.
Engine Air Cleaner/Filter
The engine air cleaner/lter is located in the
engine compartment on the driver’s side of the
vehicle. SeeEngine Compartment Overview
on page 346for more information on location.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (83 000 km) interval. See
Scheduled Maintenance on page 473for more
information. If you are driving in dusty/dirty
conditions, inspect the lter at each engine oil
change.

How to Add Automatic Transaxle Fluid
Refer to the Maintenance Schedule to determine
what kind of transaxle uid to use. See
Recommended Fluids and Lubricants on page 483.
If the uid level is low, add only enough of the
proper uid to bring the level into the crosshatched
area on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at
the dipstick hole to bring it to the proper level.
It does not take much uid, generally less
than one pint (0.5 L). Do not overll.
Notice:Use of the incorrect automatic
transaxle uid may damage your vehicle, and
the damages may not be covered by your
warranty. Always use the automatic transaxle
uid listed inRecommended Fluids and
Lubricants on page 483.
3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transaxle Fluid,” earlier in this section.
4. When the correct uid level is obtained, push
the dipstick back in all the way.
Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant
is designed to remain in the vehicle for ve years
or 150,000 miles (240 000 km), whichever
occurs rst, if only DEX-COOL
®extended life
coolant is added.
The following explains the cooling system and
how to add coolant when it is low. If there is
a problem with engine overheating or if coolant
needs to be added to the radiator, seeEngine
Overheating on page 364.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®engine coolant will:
Give freezing protection down to
−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.

Windshield Replacement
If your vehicle is equipped with the Head-Up
Display (HUD) system, keep in mind that your
windshield is part of the HUD system. If you ever
have to get your windshield replaced, be sure
to get one that is designed for HUD or your HUD
image may look blurred or out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear or cracking. SeeScheduled Maintenance
on page 473for more information on wiper blade
inspection.Replacement blades come in different types and
are removed in different ways. For the proper type
and length, seeNormal Maintenance Replacement
Parts on page 484. Here is how to remove the
wiper blade:
1. Pull the windshield wiper arm connector away
from the windshield.
2. While holding the wiper arm, pull the clip up
from the blade connecting point, and pull the
blade assembly down toward the windshield
to remove it from the wiper arm.
3. Install the new wiper blade onto the wiper arm
and snap the clip into place.
