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.

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.
Maintenance
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.
SeeMaintenance Schedule on
page 11‑3. 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 10‑10.

Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
cannot be seen or smelled.
It can cause unconsciousness
and even death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
(Continued)
WARNING (Continued)
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in
the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑26.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (Carbon
Monoxide) gas to get inside.
CO could overcome you and
kill you. You cannot see it or
smell it, so you might not know
it is in your vehicle.

Starting the Engine
Move the shift lever to P (Park) or
N (Neutral) for an automatic
transmission. For a manual
transmission the vehicle can be
started in Neutral or any other gear
as long as the clutch pedal is
pressed. To restart a vehicle with a
manual transmission when you are
already moving, use the Neutral
position only. To restart a vehicle
with an automatic transmission
when you are already moving, use
N (Neutral).
Notice:Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
The RKE transmitter must be inside
the vehicle for the ignition to work. Cell phone chargers can interfere
with the operation of the Keyless
Access System. Battery chargers
should not be plugged in when
starting or turning off the engine.
To start the vehicle, do the following:
1. For vehicles with an automatic
transmission, with your foot on
the brake pedal, press the
START button located on the
instrument panel. For vehicles
with a manual transmission, you
must also press in the clutch
pedal while pressing the
START button.
If there is not an RKE transmitter
in the vehicle or if there is
something causing interference
with it, the DIC will display
NO FOBS DETECTED.
See Key and Lock Messages on
page 5‑43 for more information. 2. When the engine begins
cranking, let go of the button and
the engine cranks automatically
until it starts. If the battery in the
RKE transmitter is weak, the
DIC displays FOB BATTERY
LOW. You can still drive the
vehicle.
See “Battery Replacement”
under Remote Keyless Entry
(RKE) System Operation on
page 2‑3 for more information.
If the fob battery is dead, you
need to insert the fob into the
fob slot to enable engine
starting. See “NO FOBS
DETECTED” underKey and
Lock Messages on page 5‑43.
3. Do not race the engine immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.

4. If the engine does not start andno DIC message is displayed,
wait 15 seconds before trying
again to let the cranking motor
cool down.
If the engine does not start after
5-10 seconds, especially in very
cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor while cranking for up
to 15 seconds maximum. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool down. When the engine
starts, let go of the accelerator.
If the vehicle starts briefly but
then stops again, repeat these
steps. This clears the extra
gasoline from the engine.
Notice: Cranking the engine for
long periods of time, by pressing
the START button immediately
after cranking has ended, can
overheat and damage the
cranking motor, and drain the battery. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. Once cranking has
been initiated, the engine continues
cranking for a few seconds or until
the vehicle starts. If the engine does
not start, cranking automatically
stops after 15 seconds to prevent
cranking motor damage. To prevent
gear damage, this system also
prevents cranking if the engine is
already running.
Notice:
The engine is designed to
work with the electronics in the
vehicle. If electrical parts or
accessories are added, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.Stopping the Engine
If the vehicle has an automatic
transmission, move the shift lever to
P (Park) and press and hold the
Acc. (Off/Accessory) button, located
on the instrument panel, until the
engine shuts off. If the shift lever is
not in P (Park), the engine shuts off
and the vehicle goes into the
accessory mode. The DIC displays
SHIFT TO PARK. Once the shifter is
moved to P (Park), the vehicle turns
off. If the vehicle has a manual
transmission, it is recommended
that you move the shift lever to
R (Reverse) and set the parking
brake after you turn off the
engine by pressing and holding
the Acc. (Off/Accessory) button.
If the RKE transmitter is not
detected inside the vehicle when it
is turned to off, the DIC displays
NO FOB –OFF OR RUN?.

9-42 Driving and Operating
Launch Control
A Launch Control feature is
available, within Competitive Driving
Mode (except ZR1) or Performance
Traction Management (Z06, ZR1),
on vehicles with a manual
transmission to allow the driver to
achieve high levels of vehicle
acceleration in a straight line.
Launch Control is a form of traction
control that manages tire spin while
launching the vehicle. This feature
is intended for use during closed
course race events where
consistent zero to sixty and quarter
mile times are desirable.
Launch Control is only available
when the following criteria are met:
.Competitive Driving Mode is
selected (except ZR1) or any of
the Performance Traction
Management modes are
selected (Z06, ZR1). The TCS
light comes on the instrument
panel and the appropriate DIC
message displays.
.The vehicle is not moving.
.The steering wheel is pointing
straight.
.The clutch is pressed and the
vehicle is in first gear.
.The accelerator pedal is rapidly
applied to wide open throttle.
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle.
A smooth, quick release of the
clutch, while maintaining the fully
pressed accelerator pedal, will
manage wheel slip. Complete shifts
as described in Manual
Transmission on page 9‑32.
After the vehicle is launched, the
system continues in Competitive
Mode (except ZR1) or Performance
Traction Management (Z06, ZR1). Competitive Driving Mode,
Performance Traction Management,
and Launch Control are systems
designed for a closed course race
track and not intended for use on
public roads. The systems are not
intended to compensate for lack of
driver experience or familiarity with
the race track.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow,
mud, ice, sand or gravel. It works
like a standard axle most of the
time, but when traction is low, this
feature allows the drive wheel with
the most traction to move the
vehicle.

Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Look for the TOP TIER label on the
fuel pump to ensure gasoline meets
enhanced detergency standards
developed by auto companies. A list
of marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
The eighth digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle's engine.
The VIN is at the top left of the
instrument panel. SeeVehicle
Identification Number (VIN) on
page 12‑1.
Recommended Fuel
If the vehicle has the 6.2L V8 engine
(VIN Code W), use premium
unleaded gasoline with a posted
octane rating of 91 or higher. You
can also use regular unleaded
gasoline rated at 87 octane or
higher, but the vehicle's acceleration
could be slightly reduced, and a
slight audible knocking noise,
commonly referred to as spark
knock, might be heard. If the octane
is less than 87, a heavy knocking
noise might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. Otherwise, you could
damage the engine. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.
