Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode,
the air-conditioning compressor and the fan speed.
AUTO will appear on the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C). An initial
setting of 73°F (23°C) is suggested.
Choosing the warmest or coldest temperature
setting will not cause the system to heat or cool
any faster. If you set the system at the warmest
or coldest temperature setting, the system will
remain in manual mode at that temperature and
it will not go into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will start
out blowing air at the oor but may change modes
automatically as the vehicle warms up to maintain
the chosen temperature setting. The length of time
needed for warm up will depend on the outside
temperature and the length of time that has elapsed
since your vehicle was last driven.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 3-64for 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
wPWRx(Power/Temperature):Press the PWR
button on the left side of the climate control panel to turn
the entire climate control system on or off. Press the
up or down arrow on the switch to manually increase or
decrease the temperature inside the vehicle.
3-42

((Heated/Cooled Seat):Press this button to turn the
feature on. The button on the left controls the driver’s
seat and the button on the right controls the passenger’s
seat. Each press of the button will take you to a
different setting. The settings available in order are
HI HEAT, LO HEAT, OFF, HI COOL, LO COOL
and OFF. You will be able to feel the temperature
change in a few minutes.
The feature will automatically turn off when the vehicle
is turned off.
?(Recirculation):Press this button to turn the
recirculation mode on or off. The air-conditioning
compressor also comes on. This mode keeps outside
air from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to
help cool the air inside your vehicle more quickly.
Recirculation is not available in defrost or oor/defog
modes.
Using recirculation for long periods of time may cause
the air inside your vehicle to become too dry. To prevent
this from happening, after the air in your vehicle has
cooled, turn the recirculation mode off.
Sensors
There are sensors to measure the temperature and
sun’s effect on passenger comfort.
The solar sensor on your vehicle monitors the solar
radiation then uses the information to maintain the
selected temperature when operating in AUTO mode by
initiating needed adjustments to the temperature, the
fan speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing
the sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located on
the top of the instrument panel near the windshield
or the system will not work properly.
There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps maintain the temperature inside the vehicle.
The outside temperature will be displayed in the
navigation system only when the engine is running.
Any cover on the front of the vehicle could give a false
reading of the temperature.
3-44

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
=(Rear Window Defogger):Press this button to
turn the rear window defogger on or off. Be sure to clear
as much snow from the rear window as possible.
The rear window defogger will turn off approximately
10 minutes after the button is pressed when traveling
less than 30 mph (48 km/h). If turned on again, the
defogger will only run for approximately ve minutes
before turning off. The defogger can also be turned
off by pressing the button again or by turning off
the engine.The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirrors
when the rear window defogger is on.
The rear window defogger and heated mirrors are
automatically disabled when the retractable hardtop is
moving or down.
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
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.
To check or replace the air lter, do the following:
1. With the hood open, unlatch and remove the
access panel.
The passenger compartment air lter and access
panel are located on the passenger’s side of
the engine compartment near the battery.
SeeEngine Compartment Overview on page 6-12
for more information on location.
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.

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 briey when you start the
engine just to let you know they are 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 is 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 are a big help.
Your vehicle may also have a Driver Information Center
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-64.

Speedometer and Odometer
Your speedometer lets you see your speed in either
miles per hour (mph) or kilometers per hour (km/h).
There is only one scale for mph and km/h. Use
the Driver Information Center (DIC) controls to switch
between mph and km/h. SeeDIC Controls and Displays
on page 3-64for more information. The cluster will
calculate the proper speed and move the needle to the
correct position. Either the MPH or the km/h telltale
will illuminate, depending on which measurement you
choose.
The odometer is part of the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 3-64for more information.
Trip Odometer
The trip odometer is part of the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 3-64for more information.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Fuel will shut off at about 6700 rpm.
If you continue to drive your vehicle at the fuel shut off
rpm, you could damage your engine. Be sure to
operate your vehicle below the fuel shut off rpm or
reduce your rpm quickly when the fuel shuts off.
Safety Belt Reminder Light
When the ignition button is pressed to START, a chime
will be provided for several seconds to remind people
to buckle their safety belts. The driver safety belt
light will also be provided and stay on for several
seconds, then it will ash for several more. You should
buckle your seat belt.
This chime and light will
be repeated if the driver
remains unbuckled and
the vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor the
light will be provided.
3-50

Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of your
battery. When the
engine is running,
it shows the voltage
output of the charging
system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel
cluster and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when your vehicle is at 10 volts or below. Have
it checked right away. Driving with the voltmeter
reading at 10 volts or below could drain your battery
and disable your vehicle.
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.
This light should come on when you start the engine.
If it does not come on then, have it xed so it will
be ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-29
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.

that the pedal is harder to push. Or, the pedal may go
closer to the oor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 5-37.
{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay
on for several seconds.
That is normal.
If the light stays on, turn the ignition off. Or, if the light
comes on when you are driving, stop as soon as possible
and turn the ignition off. Then start the engine again to
reset the system. If the light still stays on, or comes on
again while you are driving, your vehicle needs service.
If the regular brake system warning light is not on, you
still have brakes, but you do not have anti-lock brakes.
If the regular brake system warning light is also on, you
do not have anti-lock brakes and there is a problem with
your regular brakes. See “Service ABS” underDIC
Warnings and Messages on page 3-67.
The anti-lock brake system warning light will come on
briey when you turn the ignition on. This is normal.
