Climate Control Influence on
Fuel Economy
The climate control system
depends on other vehicle
systems for heat and power
input. Certain climate control
settings can lead to higher
fuel usage.

Sensors
The solar sensor, located 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.
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 coveron 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 outlet 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.
Afterblow Feature
If equipped, under certain
conditions, the fan may stay
on or may turn on and off
several times after you turn
off and lock the vehicle. This is
normal.
Air Vents
Adjustable air vents are in the
center and on the sides of the
instrument panel, and on the
rear of the center console
storage.
Move the slider knobs to
change the direction of or to
close off the airflow.
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 visibility and help
decrease moisture drawn
into the vehicle.
.Keep the path under the
front seats clear of objects
to help circulate the air
inside of the vehicle more
effectively.
.Use of non-GM approved
hood deflectors can
adversely affect the
performance of the system.

Climate Controls 239
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 Schedule0471.
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.
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 Schedule
0 471.

economy possible:
.Set the climate controls to
the desired temperature
after the engine is started,
or turn them off when not
required.
.Avoid fast starts and
accelerate smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for
long periods of time.
.When road and weather
conditions are appropriate,
use cruise control.
.Always follow posted speed
limits or drive more slowly
when conditions require.

242 Driving and Operating
.Keep vehicle tires properly
inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires
with the same TPC Spec
number molded into the
tire's sidewall near the size.
.Follow recommended
scheduled maintenance.
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.
Refer to the infotainment
section for more information
on using that system and the
navigation system, if equipped,
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 seat belt. See Seat Belts
0 55.

260 Driving and Operating
applied sooner than when on
dry pavement. See Antilock
Brake System (ABS)0287.
.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.
.Select All-Wheel Drive (AWD)
Mode for vehicles equipped
with AWD. Select Snow/Ice
Mode for FWD only vehicles.
See Driver Mode Control
0293 and
All-Wheel Drive 0287.
Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
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

489. 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
(Continued)
Warning (Continued)
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 fan speed to the
highest setting. See
“Climate Control Systems.”
