3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Controls
and Displays on page 3-61for more information.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.Manual Operation

Use the thumbwheel 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 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
odor and 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 early.
The lter should be replaced as part of the routine
scheduled maintenance. SeeScheduled Maintenance
on page 7-4for more information.
The passenger compartment air lter is located on the
passenger’s side of the engine compartment near
the battery. SeeEngine Compartment Overview on
page 6-12for more information on location.
To check or replace the air lter, do the following:
1. With the hood open, unlatch and remove the
access panel.
2. Pull the old lter out of the housing.
3. Insert the new lter into the housing. The lter should
be fully inserted with the arrows pointing up.
4. Reinstall the air lter access panel.

Engine Oil Pressure Gage
The engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still
be considered normal. It may vary with engine speed,
outside temperature and oil viscosity. The Driver
Information Center (DIC) may display messages
regarding the oil condition. SeeDIC Warnings and
Messages on page 3-64andEngine Oil on page 6-13.
{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. United States

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 6-12for
the location of the engine air cleaner/lters.
When to Inspect the Engine Air
Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace at the rst oil change after
50,000 miles (83 000 km). SeeScheduled Maintenance
on page 7-4for more information. If you are driving
in dusty/dirty conditions, inspect the lters at each
engine oil change.
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 lters, do the following:
1. Flip the clasps on the top of the engine air
cleaner/lter cover forward to unlatch the cover.
2. Lift the front of the cover at an angle and remove.
This is necessary due to the four tabs located on
the rear of the cover.
3. Remove the engine air cleaner/lter element and
any loose debris that may be found in the air
cleaner base.

Automatic Transmission Fluid
How to Check
It is not necessary to check the transmission uid level.
A transmission uid leak is the only reason for uid
loss. If a leak occurs, take the vehicle to your dealer
service department and have it repaired as soon
as possible.
There is a special procedure for checking and changing
the transmission uid. Because this procedure is difficult,
you should have this done at your dealer service
department. Contact your dealer for additional
information or the procedure can be found in the service
manual. To purchase a service manual, seeService
Publications Ordering Information on page 8-12.
Notice:Use of automatic transmission uid labeled
other than DEXRON
®-III, Approved for the
H-Specication, may damage your vehicle, and the
damages may not be covered by your warranty.
Always use automatic transmission uid labeled
DEXRON
®-III, Approved for the H-Specication.Change both the uid and lter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
High performance operation.
If you do not use your vehicle under one of these
conditions, change the uid and lter every
100,000 miles (166 000 km).
SeeScheduled Maintenance on page 7-4for the proper
service intervals for the transmission uid and lter.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating
on page 6-23.
6-20

Brakes
Brake Fluid
Your brake master cylinder
reservoir is lled with
DOT-3 brake uid. See
Engine Compartment
Overview on page 6-12for
the location of the
reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down. The rst is that the
brake uid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the uid level goes back up. The other reason is
that uid is leaking out of the brake system. If it is, you
should have your brake system xed, since a leak
means that sooner or later your brakes will not work
well, or will not work at all.So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you add uid
when your linings are worn, then you will have too
much uid when you get new brake linings. You should
add or remove brake uid, as necessary, only when
work is done on the brake hydraulic system.
{CAUTION:
If you have too much brake uid, it can spill on
the engine. The uid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
uid only when work is done on the brake
hydraulic system. See “Checking Brake Fluid”
in this section.
Refer to the Maintenance Schedule to determine when
to check your brake uid. SeeScheduled Maintenance
on page 7-4.
