152 Climate Controls
For best results, clear all snow and
ice from the windshield before
defrosting.
A/C :Press to turn the air
conditioning system on or off. If the
climate control system is turned off
or the outside temperature falls
below freezing, the air conditioner
will not run.
Pressing this button cancels
automatic air conditioning and turns
off the air conditioner. Press AUTO
to return to automatic operation and
the air conditioner runs
automatically as needed. When the
indicator light is on, the air
conditioner runs automatically to
cool the air inside the vehicle or to
dry the air needed to defog the
windshield faster.
@: Press to turn on recirculation.
An indicator light comes on. Air is
recirculated to quickly cool the
inside of the vehicle or prevent
outside air and odors from entering.
Auto Defog : The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high humidity is detected, the climate
control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation.
To turn Auto Defog off or on, see
“Climate and Air Quality”
under
Vehicle Personalization 0134.
Rear Window Defogger
=:Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The defogger only works when the
ignition is in ON/RUN. The defogger
turns off if the ignition is in the ACC/
ACCESSORY or LOCK/OFF
position.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization 0134.
When Auto Rear Defog is selected,
the rear window defogger turns on automatically when the interior
temperature is cold and the outside
temperature is about 4 °C (40 °F)
and below. The auto rear defogger
turns off automatically after about
10 minutes, or after five minutes if
the outside temperature is not
as cold.
If the vehicle is equipped with
heated outside rearview mirrors,
they turn on when the rear window
defogger button is on and help to
clear fog or frost from the surface of
the mirror. See
Heated Mirrors 042.
Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything
else that is sharp. This may
damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.

Remote Start Climate Control
Operation (If Equipped) :
If equipped with the remote start
feature, the climate control system
may run when the vehicle is started
remotely. The system uses the
driver ’s previous settings to heat or
cool the inside of the vehicle. The
rear defog may come on during
remote start based on cold ambient
conditions. If the vehicle has heated
or ventilated seats, they may come
on during a remote start.
See Remote Vehicle Start 032 and
Heated Front Seats 052.
Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise
the automatic climate control system
may not work properly.
Air Vents
Use the louvers located on the air
vents to change the direction of the
airflow.
To open a vent, move the
thumbwheel to | . To close the vent,
move the thumbwheel to
9.
Operation Tips
. Keep all outlets open whenever
possible for best system
performance.
. Keep the paths under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.

Maintenance
Air Intake
Clear away any ice, snow, or leaves
from the air intake at the base of the
windshield that can block the flow of
air into the vehicle.
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
SeeMaintenance Schedule 0294
for replacement intervals. For more
information, see your dealer.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.

Driving Information
Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local
governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, always
keep your eyes on the road, hands
on the wheel, and mind on the drive.
. Do not use a phone in
demanding driving situations.
Use a hands-free method to
place or receive necessary
phone calls.
. Watch the road. Do not read,
take notes, or look up
information on phones or other
electronic devices.
. Designate a front seat
passenger to handle potential
distractions. .
Become familiar with vehicle
features before driving, such as
programming favorite radio
stations and adjusting climate
control and seat settings.
Program all trip information into
any navigation device prior to
driving.
. Wait until the vehicle is parked
to retrieve items that have fallen
to the floor.
. Stop or park the vehicle to tend
to children.
. Keep pets in an appropriate
carrier or restraint.
. Avoid stressful conversations
while driving, whether with a
passenger or on a cell phone.
{Warning
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.

162 Driving and Operating
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. SeeRoadside
Assistance Program 0313. 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 snow:
(Continued)
Warning (Continued)
.Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side
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 circulate the air
inside the vehicle and set
the fan speed to the highest
setting. See “Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0175.
To save fuel, run the engine for
short periods to warm the vehicle
and then shut the engine off and
partially close the window. Moving
about to keep warm also helps. If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle and to
signal for help with the headlamps.
Do this as little as possible, to
save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See
Traction
Control/Electronic Stability Control
0 183.

Vehicle Care 261
Uniform Tire Quality
Grading
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires by
treadwear, traction, and
temperature performance. This
applies only to vehicles sold in
the United States. The grades
are molded on the sidewalls of
most passenger car tires. The
Uniform Tire Quality Grading
(UTQG) system does not apply
to deep tread, winter tires,
compact spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production
tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements andadditional General Motors Tire
Performance Criteria (TPC)
standards.
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200 Traction AA
Temperature A
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one and
one-half (1½) times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart significantly from the
norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.
Traction
The traction grades, from
highest to lowest, are AA, A, B,
and C. Those grades represent
the tire's ability to stop on wet
pavement as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning, or peak traction
characteristics.
