During that delay, the instrument
panel cluster may not be as bright
as usual. Make sure the instrument
panel brightness knob is in the full
bright position. SeeInstrument
Panel Illumination Control on
page 6‑5 for more information.
If it is dark enough outside and
the exterior lamp control is off, a
HEADLAMPS SUGGESTED
message will display on the Driver
Information Center (DIC). See Lamp
Messages on page 5‑45.
Turning the exterior lamp control to
off a second time, or turning on the
headlamps will remove the
HEADLAMPS SUGGESTED
message in the DIC. If the parking
lamps or the fog lamps were turned
on instead, the HEADLAMPS
SUGGESTED message will
continue to be displayed. The regular headlamp system
should be turned on when needed.
To turn off the DRL, turn the exterior
lamp control to the off position or
shift into P (Park). The DRL will stay
off until the control is toggled again
or the vehicle is shifted out of
P (Park).
This procedure applies only to
vehicles first sold in the United
States.
Twilight Sentinel
Twilight Sentinel®is an automatic
headlamp system. When activated,
this feature turns your headlamps
and parking lamps on and off by
sensing how dark it is outside.
Be sure not to cover the light sensor
on the top of the instrument panel.
AUTO: Activates the system.
If the band is already in the AUTO
position when you start your vehicle,
Twilight Sentinel is automatically
enabled.
If it is dark outside, your vehicle
headlamps and parking lamps will
turn on automatically.
Once it is bright enough outside, the
headlamps and parking lamps will
automatically turn back off.
Twilight Sentinel may also turn on
when you drive through a dimly
lit area.

8-2 Climate Controls
When the vehicle is first started,
the display shows the driver's
temperature setting, the outside
temperature, the fan speed, and the
air delivery, for about 10 seconds.
The outside temperature is shown in
the center of the display. The digital
display will show the readings in
Fahrenheit or Celsius. See
“Personal Options”underVehicle
Personalization on page 5‑55 for
information on changing your
display.
Automatic Operation
AUTO (Automatic): Press the
AUTO button to place the entire
system in the automatic mode.
When automatic operation is active,
the system automatically controls
the inside temperature, the air
delivery mode, and the fan speed.
After a 10 second display of the
current settings, the word AUTO,
the driver's temperature setting and
the outside temperature will be
shown. The system operates to
reach the set temperature as quickly as possible. The AUTO control
system works best with the windows
up and the removable roof installed
or the convertible top up.
1. Press the AUTO button.
2. Adjust the temperature to a
comfortable setting between
16°C (60°F) and 32°C (90°F).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster. A setting of 23°C
(73°F) is suggested.
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 starts out
blowing air at the floor but may
change modes automatically as
the vehicle warms up to maintain
the chosen temperature setting.
The length of time needed for
warm up depends on the outside
temperature and the length of
time that has elapsed since the
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.
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
Driver Power/Temperature: Press
the driver temperature knob to turn
the climate control system off. This
is the only setting that completely
shuts off the fan. The digital display
shows only the outside temperature.
The driver and the passenger set
temperature and the air intake mode
can still be adjusted when the
climate control is off.
Passenger Power/Temperature:
Press the passenger temperature
knob to turn the passenger's climate
control system on or off. Turn the
knob to increase or decrease the
temperature for the passenger.

^(Air Conditioning Off):Press to
turn the air conditioning compressor
off. Press AUTO to return to
automatic operation. When in
AUTO, the air conditioning
compressor comes on automatically,
as needed.
Air conditioning does not operate at
temperatures below about 2°C to
4°C (35°F to 40°F). In temperatures
above 4°C (40°F), the air
conditioning cannot be turned off in
defrost and defog, as it helps to
remove moisture from the vehicle.
It also helps to keep the windows
clear.
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.

Climate Controls 8-5
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
one‐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.
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.

The ZR1, Z06, and Grand Sport
models also have an electronic
brake pad wear sensor system.
When pads are worn, the CHANGE
BRAKE PADS message displays
in the Driver Information Center.
SeeBrake System Messages on
page 5‑37.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Brake linings should always be
replaced as complete axle sets. Brake Rotor Wear
ZR1 models have, and Z06 and
Grand Sport models may have,
ceramic brake rotors. Rotors should
be visually inspected whenever the
brake pads are replaced. Rotors
also need to be weighed before
brake pads are replaced to confirm
that the rotor mass is greater than
the wear‐out mass printed on the
rotor. The rotor can be reused if the
weight of the rotor is above the
mass limit. Rotor inspection and
weighing methods can be found in
the service manual. See
Service
Publications Ordering Information
on page 13‑17. Brake Rotor Protector
{WARNING
Ceramic rotors will be very hot
after operation and touching them
may cause burns. Be sure brake
system is completely cool prior to
installation of protector, or coming
in contact with them.
Notice: Rotors may be chipped if
hard contact is made with the
wheel during wheel installation or
removal. Always use the rotor
protectors. Be sure to carefully
follow wheel removal and
installation instructions.

If a tire goes flat, there is no need to
stop on the side of the road to
change the tire. Continue driving,
however, do not drive too far or too
fast. Driving on the tire may not be
possible if there is permanent
damage. The tire can be driven with
no air pressure for up to 105 km
(65 miles) at speeds slower than
90 km/h (55 mph). The shorter the
distance and the slower the speed,
the greater the chance the tire will
not have to be replaced. As soon as
possible, contact the nearest
authorized GM or run-flat servicing
facility for inspection and repair or
replacement. When driving on a
deflated run-flat tire, avoid potholes
and other road hazards that could
damage the tire and/or wheel
beyond repair. When a tire has been
damaged, or if driven any distance
on a deflated run-flat tire, check with
an authorized run-flat tire service
center to determine whether the
tire can be repaired or should be
replaced. To maintain the run-flat
feature, all replacement tires must
be run-flat tires.To locate the nearest GM or run-flat
servicing facility, call Roadside
Assistance. See
Roadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10 for details.
The valve stems on run-flat tires
have sensors that are part of the
TPMS. See Tire Pressure Monitor
System on page 10‑68. These
sensors contain batteries that are
designed to last for 10 years
under normal driving conditions.
See your dealer for wheel or sensor
replacement.
Notice: Using liquid sealants can
damage the tire valves and tire
pressure monitor sensors in the
run-flat tires. This damage is not
covered by the vehicle warranty.
Do not use liquid sealants in
run-flat tires.Low-Profile Tires
Low‐Profile Performance Tire
The original equipment tires on
this vehicle are classified as
low‐profile performance tires.
These tires are designed for
very responsive driving on wet
or dry pavement, however, may
produce more road noise and
tend to wear faster.
Notice: Low‐profile tires are
more susceptible to damage
from road hazards or curb
impact than standard profile
tires. Tire and/or wheel
assembly damage can occur
when coming into contact
with road hazards like,
potholes, or sharp edged

Tire Pressure for
High-Speed Operation
{WARNING
Driving at high speeds, 160 km/h
(100 mph) or higher, puts an
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
inflation pressure adjustment for
high-speed operation. When
speed limits and road conditions
are such that a vehicle can be
driven at high speeds, make sure
the tires are rated for high-speed
operation, in excellent condition,
and set to the correct cold tire
inflation pressure for the
vehicle load.The tires require inflation pressure
adjustment when driving the vehicle
at speeds of 282 km/h (175 mph) or
higher, where it is legal. Set the cold
inflation pressure to the maximum
inflation pressure shown on the
tire sidewall, or 265 kPa (38 psi),
whichever is lower. See the
example following. Return the tires
to the recommended cold tire
inflation pressure when high-speed
driving has ended. See
Vehicle
Load Limits on page 9‑14.
Example:
The maximum load and inflation
pressure molded on the tire
sidewall, in small letters, near the
rim flange. It will read something
like this: Maximum load 690 kg
(1521 lbs) 300 kPa (44 psi)
Max. Press.
For this example, set the inflation
pressure for high‐speed driving at
265 kPa (38 psi). Racing or other competitive driving
may affect the warranty coverage
of the vehicle. See the warranty
booklet for more information.Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
