The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
defogger on or off. An indicator light above 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 approximately
15 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately seven
minutes before turning off. The defogger can also be
turned off by pressing the button again or by turning off

Automatic Operation
To switch the temperature display from degrees
Fahrenheit to degrees Celsius, press and hold the
AUTO, ECON, and MODE buttons at the same time.
AUTO (Automatic):When automatic operation is active
the system will control the inside temperature, the air
delivery, and the fan speed.
OFF:Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle.
Use the steps below to place the entire system in
automatic mode:
1. Put the fan knob on AUTO and press the AUTO
button.
When AUTO is selected, the display will change to
show the current set temperature, delivery mode
and fan speed.
When auto is selected, the air conditioning operation
and air inlet will be automatically controlled. The
air conditioning compressor will run when as
necessary. The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down your vehicle. The light on the
button will illuminate in recirculation.2. Set the temperature.
To nd your comfort setting, start with a 71°F (22°C)
temperature setting and allow about two to three
minutes for the system to regulate. Turn the
temperature knob to adjust the temperature setting
as necessary. If you choose the temperature setting
of 60°F (15°C) the system will remain at the
maximum cooling setting. If you choose the
temperature setting of 90°F (32°C) the system will
remain at the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to heat or
cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield. This
sensor regulates air temperature based on sun
load, and also turns on your headlamps. See
“Sensor” later in this section for more information.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air is
available. The length of delay depends on the
engine coolant temperature. Pressing the fan switch
will override this delay and change the fan to a
selected speed.

direction of the air ow.
Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the vehicle that may block
the ow of air into your vehicle.
Use of non-GM approved hood de ectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects

Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air lter. It is located underneath the hood
just below the windshield wiper arm on the passenger’s
side of the vehicle.
The lter traps most of the pollen from air entering the
Climate Control System. Like your engine’s air
cleaner/ lter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
lter, seeScheduled Maintenance on page 6-4.For the type of lter to use, seeNormal Maintenance
Replacement Parts on page 6-13.
To change the passenger compartment air lter, use the
following steps:
1. Open the hood. Locate the passenger compartment
air ler access panel.
2. Peel back the hood weatherstrip from the
passenger’s side of the vehicle halfway to center.
3. Use a tool to open the passenger compartment air
lter access door.
4. Remove any leaves or other debris from the
lter area.

Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on brie y when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly — and even
dangerous. So please get to know your warning lights
and gages. They’re a big help.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles or kilometers.
Your vehicle has a tamper-resistant odometer. You may
wonder what happens if your vehicle needs a new
odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
If it can’t, it will be set at zero and a label must be put
on the driver’s door to show the old mileage reading
when the new odometer was installed. If the mileage is
unknown, the label should then indicate “previous
mileage unknown”.
Trip Odometer
Your trip odometer shows how far your vehicle has
been driven since the trip odometer was last reset. To
reset the trip odometer to zero, press and hold the
trip/reset button for about two seconds.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not be
covered by your warranty. Do not operate the engine
with the tachometer in the shaded warning area.
The maximum rpm is limited in PARK (P) and
NEUTRAL (N) to 4000 rpm by the vehicle’s computer.
This is to prevent engine damage.

Light
If your vehicle has anti-lock brakes, the anti-lock brake
system (ABS) warning light will come on brie y, as
a check, when you start your vehicle. If it does not, have
your vehicle serviced so that the light works properly
when it needs to.
The ABS light is located in
the instrument panel
cluster, to the left of the
engine coolant
temperature gage.
If the light stays on longer than a few seconds after you
start your engine, or comes on and stays on while
you are driving, try resetting the system.To reset the system, do the following:
1. If you are driving, pull over when it is safe to do so.
2. Be sure the vehicle is in PARK (P).

4. Then restart the engine.
If the light remains on after resetting the system or comes
on again while driving, your vehicle needs service. If the
ABS light is on, but the regular brake system warning light
is not on, you do not have anti-lock brakes, but you still
have regular brakes. Have your vehicle serviced right
away. If both brake lights are on, you do not have
anti-lock brakes, and there’s a problem with your regular
brakes as well. Have your vehicle towed for service. See
Towing Your Vehicle on page 4-32.
