Automatic Air Recirculation :When
the AUTO indicator light is on, the air
is automatically recirculated as
needed to help quickly cool the inside
of the vehicle.
@: Press to alternate between
recirculating air inside the vehicle or
pulling in outside air. The indicator
light on the button is lit when
recirculation mode is active. This
helps to quickly cool the air inside the
vehicle or reduce the outside air and
odors that may enter.
Pressing this button cancels automatic
recirculation. Press AUTO to return to
automatic operation; recirculation
runs automatically as needed.
Manual recirculation mode is not
available when in Defrost or Defog
modes.
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. 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 0135.Rear Window Defogger
K: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
rear window defogger only works
when the engine is running.
The rear window defogger turns off
automatically after about 15 minutes.
At higher vehicle speeds, the rear
window defogger may stay on
continuously.
The upper gridlines on the rear
window are antenna lines and are not
intended to heat when the defogger is
activated.
The heated outside mirrors turn on
when the rear window defogger
button is on. They help to clear fog or
frost from the surface of the mirrors. The rear window defogger can be set
to automatic operation. See
“Climate
and Air Quality” underVehicle
Personalization 0135. 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.
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 with the
remote vehicle 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. See Remote Vehicle Start
0 35.
The rear window defogger turns on if
it is cold outside.
If equipped, the heated seats will turn
on if it is cold outside. The heated
seat indicator lights may not come on
during a remote start. If equipped, the
heated steering wheel will come on in
a remote start if it is cold outside. The
heated steering wheel indicator light
may not come on.Sensor
The solar sensor 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.
If the sensor is covered, the automatic
climate control system may not work
properly.
Air Vents
Adjustable air vents are in the center

Move the slats (2) to change the
direction of the airflow.
Additional air vents are beneath the
windshield and the driver and
passenger door windows. These are
fixed and cannot be adjusted.Operation Tips
.
Clear away any ice, snow, or leaves
from air inlets at the base of the
windshield that could block the
flow of air into the vehicle.
. Clear snow off the hood to
improve visibilty and help
decrease moisture drawn into the
vehicle.
. Keep the path under the front
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. Check
with your dealer before adding
equipment to the outside of the
vehicle.
. Do not attach any devices to the
air vent slats. This restricts airflow
and may cause damage to the air
vents.
Maintenance
Passenger Compartment
Air Filter
The filter reduces 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. See
Maintenance Schedule 0327.
See your dealer regarding replacement
of the filter.
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.

168 CLIMATE CONTROLS
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.
The air conditioning system requires
periodic maintenance. See
Maintenance Schedule0327.

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, keep your
eyes on the road, keep your hands on
the steering wheel, and focus your
attention on driving.
. 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.

be applied sooner than when on
dry pavement. SeeAntilock Brake
System (ABS) 0200.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas. The
surface of a curve or an overpass
can remain icy when the
surrounding roads are clear. Avoid
sudden steering maneuvers and
braking while on ice.
. Turn off cruise control.
Blizzard Conditions
Stay with the vehicle unless there is
help nearby. If possible, use Roadside
Assistance. See Roadside Service 0350.
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:
. 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
(Continued)
Warning (Continued)
fan speed to the highest
setting. See“Climate Control
Systems.”
For more information about CO, see
Engine Exhaust 0193.
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.

300 VEHICLE CARE
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 normdue 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.
Temperature
The temperature grades are A (the
highest), B, and C, representing
the tire's resistance to the
generation of heat and its ability
to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test
wheel. Sustained high temperature
can cause the material of the tire
to degenerate and reduce tire life,
and excessive temperature can
lead to sudden tire failure. The
grade C corresponds to a level of
performance which all passenger
car tires must meet under the
Federal Motor Safety Standard
No. 109. Grades B and A represent
higher levels of performance on
the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade
for this tire is established for a tire
that is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
