The A/C does not work when the
outside temperature is below 4 °C
(40 °F). If A/C is pressed the
indicator flashes three times and
turns off to show that the A/C mode
is not available. If the A/C is on and
the outside temperature drops
below a temperature which is too
cool for air conditioning to be
effective, the A/C indicator turns off
to show that the A/C mode has
been canceled.
On hot days, open the windows
briefly to let hot inside air escape.
This helps reduce the time it takes
for the interior of the vehicle to
cool down.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
@:Press to alternate between
recirculating air inside the vehicle or
pulling in outside air. An indicator
light comes on when recirculation
mode is active. With each ignition
cycle, the recirculation mode is
reset to automatic. When the engine is turned on, outside air or
recirculation is automatically
selected for better performance.
When recirculation is activated, the
air conditioning compressor comes
on and helps to quickly cool the air
inside the vehicle. This mode also
helps to reduce the outside air and
odors that may enter the vehicle.
The recirculation mode cannot be
used with floor, defog, or defrosting
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. While in
recirculation mode the windows can
fog when the weather is cold and
damp. To clear the fog, select either
the defog or defrost mode and
increase the fan speed.
REAR :
Press to turn the rear
heating and air conditioning on or
off. See Rear Climate Control
System 0156 orRear Climate
Control System (with Rear Seat
Audio) 0157.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
R
1: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. Do
not drive the vehicle until all the
windows are clear.
The defogger only works when the
vehicle is in ON/RUN. The defogger
will turn off if the vehicle is
turned off.
If equipped with heated outside
rearview mirrors, fog or frost is
cleared from the surface of the
mirror when the rear window defog
button is pressed.
Caution
Using a razor blade or sharp
object to clear the inside rear
window can damage the rear
window defogger. Repairs would

not be covered by the vehicle
warranty. Do not clear the inside
rear window with sharp objects.
Sensors
The solar sensor in the defrost grille
in the middle of the instrument
panel, monitors the solar heat. Do
not cover the solar sensor or the
system will not work properly.
The interior temperature sensor, on
the instrument panel to the right of
the steering column, measures the
temperature of the air inside the
vehicle.
There is also an exterior
temperature sensor behind the front
grille. This sensor reads the outside
air temperature and helps maintain
the temperature inside the vehicle.
Any cover on the front of the vehicle
could cause a false reading in the
displayed temperature.The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the temperature, fan
speed, and air delivery mode. The
system may also supply cooler air to
the side of the vehicle facing the
sun. The recirculation mode will also
be used as needed to maintain cool
outlet temperatures.

Air Vents
To adjust the center and side air
outlets on the instrument panel:
.Use the slider switch in the
center of the outlet, to change
the direction of the airflow.
. Use the thumbwheel near the
outlet to control the amount of
airflow or to shut off the airflow.
There are also outlets overhead in
the rear passenger area: adjust as
needed.
Keep all outlets open whenever
possible for best system
performance.
Operation Tips
. Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
can block the flow of air into the
vehicle.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
. Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
. If fogging reoccurs while in vent
or bi-level modes with mild
temperature throughout the
vehicle, turn on the air
conditioner to reduce windshield
fogging.

and other airborne irritants from
outside air and inside air when in
recirculation mode.
The filter should be replaced as part
of routine scheduled maintenance.
See Maintenance Schedule 0289.
To find out what type of replacement
filter to use, see Maintenance
Replacement Parts 0299.

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. Refer to the Infotainment section
and the infotainment manual for
more information on using that
system, including pairing and using
a cell phone.
Defensive Driving
Defensive driving means
“always
expect the unexpected.” The first
step in driving defensively is to wear
the safety belt. See Safety
Belts 053.
. Assume that other road users
(pedestrians, bicyclists, and
other drivers) are going to be
careless and make mistakes.
Anticipate what they might do
and be ready.
. Allow enough following distance
between you and the driver in
front of you.
. Focus on the task of driving.
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.

166 Driving and Operating
.The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner
than when on dry pavement.
See Antilock Brake System
(ABS) 0182.
. 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
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. See Roadside
Assistance Program 0308. 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.
(Continued)
Warning (Continued)
.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 0178.
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.
