You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days press the AUTO
button and adjust the temperature to a cool, comfortable
setting. To achieve maximum cool down, do the
following: 1. Select
Hmode.
2. Press
?.
3. Select the a/c on.
4. Select the coolest temperature.
5. Select the highest fan speed. 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 the
vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.
?
(Recirculation) : Press to turn the recirculation
mode on or off. An indicator light comes on to show
that recirculation is on. This mode prevents outside air
from entering your vehicle. It can be used to prevent
outside air and odors from entering your vehicle and
to help cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.

Sensors
The solar sensor on the vehicle monitors the solar
heat and uses the information to maintain the selected
temperature when operating in AUTO mode by
automatically adjusting the temperature, fan speed
and 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
to maintain the temperature inside the vehicle. Any
cover on the front of the vehicle could give a false
reading in the temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
.The vehicle's speed is above 19 km/h (12 mph) for
five minutes.
.The vehicle's speed is above 52 km/h (32 mph) for
two and a half minutes. These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown when
you start the vehicle. If it has been turned off for less
than three hours, the temperature will be recalled from
the previous vehicle operation.
There is also an inside temperature sensor located to
the left of the ignition switch. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
properly.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger only works when the engine
is running.
=(Rear Window Defogger) :
Press to turn the
rear window defogger on or off. Be sure to clear
as much snow from the rear window as possible.
An indicator light comes on to show that the rear
window defogger is on.
4-26
Page 195 of 472

The rear window defogger turns off about 10 minutes
after the button is pressed when traveling less than
48 km/h (30 mph). If turned on again, the defogger
only runs for about five minutes before turning off.
The defogger can also be turned off by turning off
the engine.
The vehicle has heated outside rearview mirrors.
The mirrors will heat to help clear fog or frost from the
surface of the mirrors when the rear window defogger
button is pressed.
For vehicles with a power convertible top, the rear
window defogger and heated mirrors are automatically
disabled when the power convertible top 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 the vehicle warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.Outlet Adjustment
Use the tab located on the air outlets to change the
direction of the airflow.
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 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 filter removes certain
particles from the air including pollen and dust particles.
Reductions in airflow, which may occur more often in
dusty areas, indicate that the filter may need to be
replaced. See Scheduled Maintenance
on page 7‑3for information on how often to replace the filter.
Notice: Driving without a passenger compartment
air filter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the
old filter with a new one.
The passenger compartment air filter is located on the
passenger side of the engine compartment near the
battery. See Engine Compartment Overview
on
page 6‑14. To check or replace the air filter:
1. Remove the cover retainer clips (A) from the
passenger compartment air filter cover.
2. Remove the cover.

3. Remove the filter and install the new air filter.
4. Replace the filter cover.
5. Attach the retainer clips.
Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
the warning lights and gauges could prevent injury.
Warning lights come on when there might be or there
is a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gauges can indicate when there might be or there
is a problem with one of the vehicle's functions. Often
gauges and warning lights work together to indicate a
problem with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gauges shows there
could be a problem, check the section that explains
what to do. Follow this manual's advice. Waiting to do
repairs can be costly and even dangerous.

Speedometer and Odometer
The speedometer shows the speed in either kilometers
per hour (km/h) or miles per hour (mph). For more
information see “Personal Options” underDIC Vehicle
Personalization on page 4‑71.
To read the odometer with the ignition off, turn on the
parking lamps.
If the vehicle needs a new odometer installed, the
mileage total of the new odometer will be set to the
original kilometers (miles) of the old odometer. See your
dealer/retailer if the odometer must be replaced in the
vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Notice: Fuel shuts off at about 6500 rpm for
the base model, 7000 rpm for the Z06 model, and
6600 rpm for the ZR1 model. If the vehicle continues
to be driven at the fuel shut off rpm, the engine
could be damaged. Be sure to operate the vehicle
below the fuel shut off rpm or reduce the vehicle's
rpm quickly when the fuel shuts off.
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime sounds for several
seconds to remind a driver to fasten the safety belt,
unless the driver safety belt is already buckled.
The safety belt light
comes on and stays on
for several seconds, then
flashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor
the light comes on.
