Climate Controls
Climate Control System
With this system you can control the heating, cooling,
and ventilation for your vehicle.
Operation
To change the current mode, turn the right control to
select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
%(Bi-Level):This mode directs the air to the
instrument panel outlets and the floor outlets. This
position can be used for most winter driving.
[(Floor):This mode directs the air to the
floor outlets.
The right control can also be used to select defog or
defrost modes. Information on defogging and defrosting
can be found later in this section.
9(Fan):Turn the left control clockwise or
counterclockwise to increase or decrease the fan speed.
The fan must be on to run the air-conditioning
compressor.
>(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.
Move the right control to this position to turn recirculation
on. Turn the air conditioning on when using recirculation.
Recirculation is not recommended for use over long
periods of time.
Temperature Control:Turn the center control
clockwise or counterclockwise to increase or decrease
the temperature inside your vehicle.
3-19

1(Defrost):This mode directs the air to the
windshield. When you select this mode, the system
turns off recirculation automatically. The recirculation
mode cannot be selected while in the defrost mode. Do
not drive the vehicle until the windscreen is clear
To help clear the windscreen quickly, do the following:
1. Select the defrost mode.
2. Select the highest temperature.
3. Select the highest fan speed.
4. Select A/C.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press this button on the right
dial to turn the rear window defogger on or off. An
indicator light in the button will come on to let your know
that the rear window defogger is activated. Be sure to
clear as much snow from the rear window as possible.
The rear window defogger will turn off about 15 minutes
after the button is pressed. The defogger can also
be turned off by pressing the button again or by turning
off the engine.Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Outlet Adjustment
Move the thumbwheel on the vents to change the
direction of the airflow. The center thumbwheel adjusts
the volume of the airflow.
There are also similar vents for the rear of the vehicle.
They are located at the rear of the center console.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect performance of the system.
•When an objectionable odor outside the vehicle is
encountered, use the recirculation mode, with the
temperature knob at a comfortable setting to prevent
the odor from entering the vehicle through the
ventilation system. This can be helpful when driving
through a long tunnel with poor ventilation.
However, extended usage of this mode in cold or
cool weather can cause window fogging.

Brake System Warning Light
This light will come on
when the ignition is turned
ON and when the
parking brake is applied.
If this light comes on and the Brake message appears
on the trip computer display while driving and the
parking brake is released, a fault with the brakes is
indicated. You should immediately stop the car on the
side of the road as carefully as possible. Do not proceed
until satisfied that braking is possible or that the
cause of the problem has been fixed.
A warning will chime if you attempt to drive off without
releasing the parking brake.
The Brake message will remain until the MODE button
on the trip computer is pressed, but the symbol will
remain until the problem is fixed.
This light will also come on to indicate low brake fluid.
Anti-Lock Brake System
Warning Light
This light will come on
briefly when the ignition is
turned to ON.
If the light does not come on then, have it fixed so it will
be ready to warn you if there is a problem.
If there is a problem with the anti-lock brake system,
this light will come on and the ABS Fault message will
appear on the trip computer display. See your GM
dealer for service. The vehicle’s brake system will still
operate without ABS.
The ABS Fault message will stay on until the MODE
button on the trip computer is pressed, but the light will
stay on until the problem is fixed.

Trip A/B
When the Time to Arrival/Distance to Arrival/Fuel
Remaining set of displays are turned on, using vehicle
personalization, and are showing on the display,
hold the MODE button down for two seconds. Now,
instead of the Time to Arrival set of displays, the
trip computer shows Trip B details.
Press the MODE button to view your displays. You now
have two different sets of trip displays counting, your
original set of trip displays — labelled A while B is
turned on — and a new set of trip displays, labelled B.
This is useful on a long trip, as Trip B can be reset
at the beginning of the journey and then locked away
by pressing the MODE button for two seconds when
Trip B is shown. Time to Arrival/Distance to Arrival/Fuel
Remaining will again be shown on the display, but
Trip B is still counting away in the background and the
original trip display can be used for short distances
during the journey. Trip B can be viewed at any time by
pressing the MODE button for two seconds when
Distance to Arrival is shown.
Trip A/B can also be enabled/disabled in vehicle
personalization. SeeVehicle Personalization on
page 2-30. If the Trip A and B function is selected,
the Average Speed and Average Fuel displays
indicate Trip A.
Trip Computer Notes:
•If the wrong buttons are accidentally pressed,
causing the display to show a display other
than normal, turn the ignition off and then on again
when the vehicle is stopped.
•Several warning lights are linked to the trip
computer displays. SeeWarning Lights, Gages, and
Indicators on page 3-22.
•When the overspeed warning symbol is first shown,
the overspeed trip computer display is automatically
shown for 10 seconds. This is to show what your
pre-selected speed is and allow you to adjust
it if desired. After 10 seconds, the trip computer
returns to its previous display.
•Some displays change the units of measurement
over time. For example, the Time to Arrival shows
hours only above 99 hours and 59 minutes, and
hours and minutes below. Time to Arrival also
shows 10 minute units above 2 hours, 5 minute
units below 2 hours and 1 minute units below
10 minutes.

Trip Computer Warning Messages
The following messages may appear on the center trip
computer display located on the instrument panel
cluster. If a message is active, it will appear on the
display for 10 seconds, unless the trip computer MODE
button is pressed. Pressing the MODE button will
acknowledge and clear messages from the display.
ABS (Anti-Lock Brake System) Fault
If this symbol and the ABS
Fault message come on,
there is a malfunction
of the anti-lock brake
system. See your
GM dealer for service.
Your vehicle’s brake system will still operate without
ABS. The ABS Fault message will remain until the
MODE button is pressed, but the symbol will remain
until the condition is repaired.
ALARM ACTIVATED
If the ALARM ACTIVATED message comes on, it
indicates that the content theft-deterrent alarm has been
set off because a door, the hood, or the trunk has
been opened, or that your vehicle’s electrical system
has been tampered with. See “How to Detect a Tamper
Condition” underContent Theft-Deterrent on page 2-14
for more information.
Brake
If this symbol and the
Brake message come on
while driving and the
park brake is released, a
fault with the brakes is
indicated.
You should immediately stop your vehicle on the side of
the road as carefully as possible. Do not proceed
until satisfied that braking is possible or the condition is
repaired. A warning will chime if you attempt to drive
off without releasing the park brake. The Brake message
will remain until the MODE button is pressed, but the
symbol will remain until the condition is repaired.
This message will also come on to indicate low
brake fluid.
3-38

Theft-Deterrent Feature
Your vehicle’s radio has an electronically coded security
system. The system recognizes the vehicle which the
radio has been installed. If the radio is kept in the
vehicle, the PIN should not be required, even if the
battery or the radio has been removed and reinstalled.
If the link between your vehicle and the radio is
disrupted, the radio will prompt you for a four-digit
PIN code to be entered.
The PIN is supplied on the security card. As the pin is
the only means of enabling operation of the radio, place
the security card in a safe place. Do not leave the
security card in the glovebox. The PIN should also be
written down and kept with other important documents.
If the security card is lost and the PIN is not recorded,
the PIN can be requested from your GM dealer,
after supplying proof of ownership. There may be a
charge for this service.
When the radio and vehicle are turned off, the blinking
red light indicates that the radio is armed.
Security Release Procedure
To type in the PIN code, do the following:
1. Turn the ignition to ON.
2. Turn the radio on. CODE____will appear on
the display.
3. Use the preset buttons to enter the PIN code.
If the wrong PIN code is entered, the radio will display
CODE ERR WAIT.
After a few seconds, the radio will display
CODE 2____,indicating that this is the
second attempt. The correct code should now
be entered. After three attempts, the radio will
display LOCK OUT 1 HR. After 1 hour, the radio will
allow another three attempts to enter the PIN.

Section 4 Driving Your Vehicle
4-1

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-27.

Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
4-7

Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may hear
the anti-lock pump or motor operate, and feel the
brake pedal pulsate, but this is normal.
Braking in Emergencies
With anti-lock brakes, you can steer and brake at the
same time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
Your vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power and applies the
brakes, as necessary.Traction control helps you to keep control of the
vehicle and reminds you to match your speed to the
road conditions.
You may feel or hear the system working, but this is
normal. The TCS is automatically turned on whenever
the ignition is turned from off to on. A Low Traction
message is displayed on the trip computer, indicating
traction control is limiting wheel spin, until the MODE
button on the trip computer is pressed. The message
then goes back to the original trip computer display with
a small low traction symbol on the left. The symbol
will remain as long as the low traction situation exists.
To limit wheel spin, especially in slippery road
conditions, you should always leave the TCS on. But
you can turn the system off if you prefer.
