180 Climate Controls
Display Function
Each time the temperature, mode,
or fan controls are adjusted, the
climate control display shows that
function along with the inside
temperature setting. The outside
temperature is displayed on the
instrument cluster.
(:Turn clockwise or
counterclockwise to turn the climate
control system on or off.
The climate control system will also
turn on if the defrost, AUTO, or air
conditioning buttons are pressed.
Automatic Operation
The system automatically controls
the fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to
the desired temperature.
When AUTO is lit, all four functions
operate automatically. Each function
can also be manually set and the
setting is displayed. Functions not
manually set will continue to be
automatically controlled, even if the
AUTO indicator is not lit. For automatic operation:
1. Press AUTO.
When AUTO is selected, the
current temperature(s) is
displayed and the AUTO
indicator light is on.
When AUTO is selected, the
air conditioning and air inlet are
automatically controlled. The
air conditioning runs when the
outside temperature is over 4 °
C (40 °F). The system is
automatically set to outside air,
unless it is hot outside and
then the air inlet changes to
recirculation mode to help
quickly cool the vehicle. The
recirculation indicator light will
come on.
2. Set the temperature for the driver and passenger.
To find a comfortable setting,
start with a 22 °C (73 °F)
temperature setting and allow
about 20 minutes for the
system to regulate. Use the
driver side or passenger side
temperature control to adjust the temperature setting as
necessary. The system will
remain at the selected setting.
Choosing the warmest or
coolest temperatures does not
cause the vehicle to heat or
cool more quickly.
To avoid blowing cold air in
cold weather, the system
delays turning on the fan until
warm air is available. Turn the
fan knob to override this delay
and select the fan speed.
Temperature Control
The driver and passenger side
temperature controls are used to
adjust the temperature of the air
coming through the system. The
temperature can be adjusted even if
the system is turned off since
outside air still enters the vehicle,
unless the recirculation mode is
selected. See “Recirculation” later in
this section.

indicator light turns off.
H: Air is directed to the instrument
panel outlets.
): Air is divided between the
instrument panel and floor outlets.
Some air is directed towards the
windshield and side window outlets.
Cooler air is directed to the upper
outlets and warmer air to the floor
outlets.
6: Air is directed to the floor
outlets, with some of the air directed
to the windshield, side window, and
second row floor outlets. In this
mode, the system uses outside air.
-: This mode clears the windows
of fog or moisture. Air is directed to
the windshield, floor outlets, and
side window vents. When this mode
is selected, the system turns off
recirculation and runs the air
conditioning compressor unless the
outside temperature is less than 4 °
C (40 °F). Do not drive the vehicle
until all the windows are clear.
0: Press to turn the defrost on or
off. This mode quickly clears the
windshield of fog or frost. Air is
directed to the windshield, side
window, and floor vents. In this
mode, outside air is pulled inside
the vehicle. The air conditioning
system runs automatically in this
setting, unless the outside
temperature is less than 4 °C (40

182 Climate Controls
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

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 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) 0210.
. 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 0334. 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 0206.
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.

202 Driving and Operating
race the engine immediately
after starting it. Operate the
engine and transmission gently
to allow the oil to warm up and
lubricate all moving parts.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold weather
(below −18 °C or 0 °F), it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you hold the key in START for
up to a maximum of
15 seconds. Wait at least
15 seconds between each try, to allow the cranking motor to
cool down. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briefly but then stops again,
repeat these steps. This clears
the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Engine Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0 °F (−18 °C). Vehicles
with an engine coolant heater
should be plugged in at least four
hours before starting. Some models
may have an internal thermostat in
the cord which will prevent engine
coolant heater operation at
temperatures above 0 °F (−18 °C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The bundled
cord is located on the driver
side of the engine
compartment, between the
engine air cleaner and the
windshield washer fluid
reservoir. See Engine
Compartment Overview 0240.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
3. Plug the cord into a normal, grounded 110-volt AC outlet.

220 Driving and Operating
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps. FCA also lights an amber
visual alert if following another
vehicle much too closely.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 40 km/h (25 mph).
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA(Continued)
Warning (Continued)
does not warn of pedestrians,
animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes. See
Defensive Driving0189.
FCA can be disabled with the
[
button on the center stack.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle ahead indicator will
display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially
blocked by pedestrians or other objects. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
