8-6 Climate Controls
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.
Air Vents
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 the
vehicle.
.Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
.Keep the area around the base
of the center stack console and
air path under the seats clear of
objects to help circulate the air
inside of the vehicle more
effectively.

9-6 Driving and Operating
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions.
But skids are always possible.
If the vehicle starts to slide,
follow these suggestions:
.Ease your foot off the
accelerator pedal and quickly
steer the way you want the
vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs.
.Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues—such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
.Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear.
Any sudden changes could
cause the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
Racing or Other
Competitive Driving
Racing or competitive driving
may affect the vehicle warranty.
See the warranty book before
using the vehicle for racing or other
competitive driving.
Notice: If you use the vehicle
for racing or other competitive
driving, the engine may use more
oil than it would with normal use.
Low oil levels can damage the
engine. For information on how
to add oil, see Engine Oil on
page 10‑14. Z06, ZR1, and Grand Sport
Coupe manual transmission only:
Be sure to check the oil level
often during racing or other
competitive driving and keep the
level at or near the upper mark
that shows the proper operating
range on the engine oil dipstick.
Except Z06, ZR1, and Grand
Sport Coupe manual
transmission: Be sure to check
the oil level often during racing or
other competitive driving and
keep the level at or near 1 L (1 qt)
above the upper mark that shows
the proper operating range on
the engine oil dipstick. After the
competitive driving, remove
excess oil so that the level on the
dipstick is not above the upper
mark that shows the proper
operating range.

9-10 Driving and Operating
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑54.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep the interior
temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

9-12 Driving and Operating
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.
(Continued)
WARNING (Continued)
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.
.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.(Continued)
WARNING (Continued)
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. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.
Run the engine for short periods
only as needed to keep warm,
but be careful.
