NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transaxle,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount
of cargo being hauled as soon as it is possible.

VENT: This setting directs outside air through the
instrument panel outlets. The air conditioning
compressor is not working when VENT is selected. If
you select VENT while in FRONT defrost, the VENT
light will flash three times to let you know this is not
allowed. This is to prevent fogging.
HTR (Heater): This setting directs most of the air
out of the floor ducts while some air will flow through
the windshield and side window outlets. The air
conditioning compressor is not working when
HTR is selected.
BLEND: When BLEND is selected, the airflow will be
split between the windshield outlets and the floor ducts.
The air conditioning compressor will be operating.
FRONT: This setting directs most of the airflow
toward the windshield.
OFF: The ventilation system always allows fresh air to
flow through your vehicle when it is moving. The
system will try to keep the air at a previously chosen
temperature. When the system is off, the blower fan is
also off.MAX (Maximum Air Conditioning): This setting
directs airflow through the instrument panel outlets. The
amount of outside air entering your vehicle is limited
with this setting. The air conditioning compressor is on
in this mode.
Also in this mode, the RECIRC function is activated
to create the maximum cooling effect in the vehicle. If
RECIRC was active before selecting MAX, the light in
the RECIRC button will go off. If RECIRC is selected
after MAX, the light in the RECIRC button will not
come on.
NORM (Normal): This setting cools the outside
air entering your vehicle and directs it through the
instrument panel outlets. The air conditioning
compressor is on in this mode.
BI
-LEV (Bi-Level): This setting directs warmer air
to the floor ducts and cooler air to the instrument panel
outlets. The air conditioning compressor is on in
this mode.

3-5
OFF: If the passenger comfort control is turned on, it
can be turned off by pressing the OFF button once.
Pressing the OFF button a second time will turn off the
main system. Turning off the main system causes the fan
to turn off and the airflow to be directed toward the
floor. The system will still try to keep the interior of the
vehicle at the previously chosen temperature setting.
The outside temperature will show on the display when
the system is off.
The ventilation system always allows fresh air to flow
through your vehicle when the vehicle is moving even
when the system is off.
VENT (Flow
-Through Ventilation): The VENT
button allows outside air to flow through your vehicle
without the air conditioning compressor working. To
turn off the VENT selection, push the VENT button
again. If you select VENT while in FRONT defrost, the
VENT light will flash three times to let you know this is
not allowed. This is to prevent fogging.RECIRC (Recirculation): When RECIRC is selected,
the system will limit the amount of outside air entering
your vehicle. This is helpful when you are trying to cool
the interior of the vehicle quickly or limit the amount of
outside air entering your vehicle. RECIRC and AUTO
may be selected at the same time. The system will remain
in RECIRC until the ignition is turned off or the RECIRC
button is pressed again. RECIRC can be selected in all
manual airflow modes except FRONT defrost and VENT.
If you select RECIRC while in FRONT defrost, the
RECIRC light will flash three times to let you know this is
not allowed. This is to prevent fogging. FRONT: This selection is used to defrost
the windshield by directing the airflow toward the
windshield. To turn off FRONT, press the AUTO
or AIR FLOW button.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the windshield and the floor. If the AIR FLOW
down button is selected while in the FRONT defrost
mode, the system will direct the air toward the floor, and
the FRONT defrost mode will cancel.
FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.

3-6 Passenger Climate Control (If Equipped)
If your vehicle is equipped with the Dual Automatic
ComforTemp system, the front seat passenger can
control the air temperature in his or her seating area. The
control is located on the passenger's door armrest.The temperature can be set up to 5
F (3
C) cooler
or warmer than the primary setting. To activate the
passenger control, press the button with the red arrow
to increase temperature. Each time you press the button, a
red indicator light will come on. To decrease temperature,
press the button with the blue arrow. Each time you press
the button a blue indicator light will come on.
If the passenger control has been turned on, it can be
turned off by pressing the OFF button on the main
system once. (Pressing the OFF button a second time
will turn off the main system.)
Automatic Operation
Press the AUTO button when you want the system to
automatically maintain a selected temperature inside of
your vehicle. When the system is set for automatic
operation, air will come from the floor ducts, instrument
panel outlets or windshield outlets depending on the
temperature inside the vehicle, the outside temperature
and sun load. Fan speed and use of air conditioning and
recirculation will vary as needed.

3-8
To program a personal choice climate control setting,
do the following:
1. Choose a temperature setting for the driver and if
desired, for the passenger. See ªDual Automatic
ComforTemp

Climate Controlº and ªPassenger
Climate Controlº earlier in this section.
2. Adjust the fan speed and the direction of the airflow.
3. Locate the memory buttons on the driver's
door panel.
4. Press a memory button (1 or 2) until you hear two
beeps. The beeps confirm that your selection has
been saved and can now be recalled.
Follow these steps each time you want to change the
stored settings. For more information on the memory
feature, see ªMemory Seat and Mirrorsº in the Index.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
If you have the electronic touch system, for quick
cool
-down on very hot days, use maximum air
conditioning with the temperature and fan speed
adjusted to COOL and HIGH. If this setting is used
for long periods of time, the air in your vehicle may
become too cold and dry.
For normal cooling on hot days, use Normal and
adjust the temperature and fan speed for your comfort.
If Recirculation is selected while in the Normal air
conditioning mode, the system works like maximum
air conditioning and recirculates the air.

3-39
Compact Disc Changer Errors
E (Error): If this message and a number appear on the
display, an error has occurred.
If the error occurred while trying to play a CD in the
compact disc player or changer, the following conditions
may have caused the error:

E30: The road is too rough. The disc should play
when the road is smoother.

E30: The disc is dirty, scratched, wet or
upside down.

E30: The air is very humid. If so, wait about an hour
and try again.

E34: The CD changer door is open. Completely
close the door to restore normal operation.

E35: An empty magazine is inserted in the CD
changer. Try the magazine again with a disc loaded
on one of the trays.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer. If your radio displays
an error number other than the error codes listed
previously, write it down and provide it to your dealer
when reporting the problem.Personal Choice Radio Controls
(If Equipped)
This feature enables two drivers to store and recall personal
settings for AM and FM presets, last tuned station, volume,
tone and audio source (radio, cassette or CD).
The memory buttons (1 or 2) for this feature are located
on the driver's door panel and correspond to the
numbers (1 or 2) found on the back of each remote
keyless entry transmitter.
To recall audio sources, press the unlock button on the
remote keyless entry transmitter and put the ignition in
RUN. The source last listened to will be recalled for the
identified driver (1 or 2).
To program this feature, do the following:
1. Set all radio preferences. For more information see
ªSetting Preset Stationsº and ªSetting the Toneº
listed for your particular radio.
2. Locate the memory buttons on the driver's door panel.
3. Press one of the memory buttons (1 or 2) until you
hear two beeps. The beeps confirm that your
selection has been saved and can now be recalled.
Follow these steps each time you want to change the
stored settings.

5-11 If No Steam Is Coming From Your Engine
If you get an engine overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:

Climb a long hill on a hot day.

Stop after high
-speed driving.

Idle for long periods in traffic.

Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. If your air conditioner is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you're in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (
)
or THIRD (3).If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn't come back on,
you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there's still no sign of steam, idle the engine for
three minutes while you're parked. If you still have
the warning, turn off the engine and get everyone
out of the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.

6-4 Gasoline Specifications
It is recommended that gasoline meet specifications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers' Association for better
vehicle performance and engine protection. Gasolines
meeting these specifications could provide improved
driveability and emission control system performance
compared to other gasolines.
In Canada, look for
the ªAuto Makers'
Choiceº label on
the pump.
Canada Only
California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label),
it is designed to operate on fuels that meet California
specifications. If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on (see ªMalfunction Indicator Lampº in the Index)
and your vehicle may fail a smog
-check test. If this
occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is
caused by the type of fuel used, repairs may not be
covered by your warranty.

6-31 Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built
-in wear indicators that make
a high
-pitched warning sound when the brake pads
are worn and new pads are needed. The sound may
come and go or be heard all the time your vehicle is
moving (except when you are pushing on the brake
pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a
brake squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in the
proper sequence to GM torque specifications.
Brake linings should always be replaced as complete
axle sets.
See ªBrake System Inspectionº in Section 7 of this
manual under Part C ªPeriodic Maintenance Inspections.º
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
