Passenger Sensing System
Your vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible when you turn your ignition
key to ON or START. The words ON and OFF or the
symbol for on and off, will be visible on the rearview
mirror during the system check. When the system check
is complete, either the word ON or the word OFF, or
the symbol for on or the symbol for off will be visible.
SeePassenger Airbag Status Indicator on page 3-30.The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbag and the side airbags (if equipped)
are not part of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat. The
sensors are designed to detect the presence of a
properly-seated occupant and determine if the
passenger’s frontal airbag should be enabled (may
inflate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun visor
says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing child is
so great, if the airbag deploys. Passenger Airbag Status Indicator – United States

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
In any setting other than off, the fan will run continuously
with the ignition on. The fan must be on in order for
the air conditioning compressor to run.To change the current mode, select one of the following
from the middle knob:
E(Vent):This mode directs air to the instrument
panel outlets.
((Bi-Level):This mode directs about half of the air
to the instrument panel outlets, and then directs the
remaining air to the floor outlets.
5(Floor):This mode directs most of the air to the
floor outlets. Some of the air will also be directed to the
windshield, instrument panel side outlets, and the
rear outlets. Be sure to keep the area under the front
seats clear to allow the flow of air to the rear
compartment.
The middle knob can also be used to select the defog
and defrost modes. Information on defogging and
defrosting can be found later in this section.
Temperature Control:Turn the right knob clockwise or
counterclockwise to manually increase or decrease
the temperature inside your vehicle. Turn the knob to the
blue area to get cool air and to the red area to get
warm air. Uplevel shown, Base similar
3-21

A/C (Air Conditioning):If your vehicle has air
conditioning, follow these steps to use the system. Start
the engine and set the fan control knob to the desired
fan speed. The air conditioning compressor does
not operate when the fan control knob is in the OFF
position. Press the A/C button to turn the air conditioning
system on and off. When A/C is pressed, an indicator
light in the button will come on to let you know that
air conditioning is activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the highest fan speed.
3. Press the A/C button.
4. Press the recirculation button.
5. Select the coolest temperature.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.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.
?(Recirculation):This mode keeps outside air
from coming into 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.
When the button is pressed, an indicator light in
the button will come on. Press this button again to
return to outside air mode.
Using the recirculation mode for extended periods may
cause your windows to fog. If this happens, select
the defrost mode.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or moisture condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or
frost from the windshield more quickly.

Charging System Light
The charging system light
will come on briefly when
you turn on the ignition,
and the engine is not
running, as a check
to show you it is working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
Have it checked by your GM dealer. Driving while this
light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
briefly when you turn the
ignition to ON. If it does not
come on then, have it
fixed so it will be ready to
warn you if there is a
problem.
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 fully
release. If it stays on after your parking brake is fully
released, it means you have a brake problem.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The Check Engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, 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:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or replacement tires that do not match your
vehicle’s original tires can affect your vehicle’s
emission controls and may cause this light to come
on. Modications 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.
When the ignition is on, this light should come on and
should go out after a few seconds as a check to
show you it is working. If the light does not 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. Diagnosis and service may be
required.
•Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.

Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including engine braking by shifting to a
lower gear. Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow
on the road to make a mirrored surface — and
slow down when you have any doubt.
If you have the anti-lock braking system (ABS),
remember: It helps avoid only the braking skid. If you do
not have ABS, then in a braking skid, where the
wheels are no longer rolling, release enough pressure
on the brakes to get the wheels rolling again. This
restores steering control. Push the brake pedal down
steadily when you have to stop suddenly. As long as the
wheels are rolling, you will have steering control.Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired — by alcohol or drugs, with night vision
problems, or by fatigue.

Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment to the
outside of your vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use regular unleaded gasoline with a posted octane
of 87 or higher. If the octane is less than 87, you may get
a heavy knocking noise when you drive. If this occurs,
use a gasoline rated at 87 octane or higher as soon as
possible. Otherwise, you might damage your engine. A
little pinging noise when you accelerate or drive uphill is
considered normal. This does not indicate a problem
exists or that a higher-octane fuel is necessary. If you are
using 87 octane or higher-octane fuel and hear heavy
knocking, your engine needs service.
Gasoline Specications
It is recommended that gasoline meet specifications
which were developed by automobile manufacturers
around the world and contained in the World-Wide Fuel
Charter which is available from the Alliance of
Automobile Manufacturers at
www.autoalliance.org/fuel_charter.htm. Gasoline
meeting these specifications could provide improved
driveability and emission control system performance
compared to other gasoline.
California Fuel
If your vehicle is certified to meet California Emission
Standards, it is designed to operate on fuels that
meet California specifications. See the underhood
emission control label. 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 and your vehicle may fail a
smog-check test. SeeMalfunction Indicator Lamp on
page 3-36. 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.

What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have a
problem properly disposing of your used oil, ask
your dealer, a service station or a local recycling center
for help.
Engine Air Cleaner/Filter
The engine air cleaner/filter is located in the engine
compartment on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 5-12
for more information on location.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the engine air cleaner/filter every 15,000 miles
(25 000 km) and replace every 30,000 miles
(50 000 km). If you are driving in dusty/dirty conditions,
inspect the filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the engine air cleaner/filter remove the filter
from the vehicle and lightly shake the filter to release
loose dust and dirt. If the filter remains caked with dirt, a
new filter is required.

{CAUTION:
An electric engine cooling fan under the hood
can start up even when the engine is not
running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
If the coolant inside the coolant surge tank is boiling, do
not do anything else until it cools down. The vehicle
should be parked on a level surface. Make sure that the
air conditioning is turned off.
The coolant level should be between the MIN and MAX
marks on the coolant surge tank when the engine is
cool. If it is not, you may have a leak at the pressure cap
or in the radiator hoses, heater hoses, radiator, water
pump or somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them. If
you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running. If
the engine is overheating, the fan should be running. If
it is not, your vehicle needs service.
Notice:Engine damage from running your engine
without coolant is not covered by your warranty.
5-25

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 will not 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.
SeeBrake System Inspection on page 6-23.
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.
