Passenger Temperature Control
The passenger temperature control
is below the passenger side
air vent.
On/Off System Operation
Press AUTO to turn the system on.
Turn the fan control knob completely
counterclockwise to turn the fan off.
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. The AUTO
indicator will turn off. Functions not
manually set will continue to be
automatically controlled, even if the
AUTO indicator is not lit.
For automatic operation:
1. Press AUTO.
2. Set the temperature. Allow the system time to stabilize. Then
adjust the temperature as
needed for best comfort.
The system operates to reach the
set temperature as quickly as
possible. The AUTO control system
works best with the windows up and
the removable roof panel installed
or the convertible top up.

needed to defog the windshield
faster.
Depending on the engine speed, the
air conditioning compressor may
shut off and turn on again and a
slight change in A/C cooling and
engine performance may be
noticed. This is normal. The system
is designed to make adjustments to
help with fuel economy while still
maintaining the selected
temperature.
If the A/C is turned off, automatic
operation is canceled.
/: Press to turn on
recirculation. An indicator light

ACCESSORY.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization 0126.
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.

The heated outside mirrors turn on
with the rear window defogger and
help to clear fog or frost from the
surface of the mirror. SeeHeated
Mirrors 045.
If equipped with a power convertible
top, the rear window defogger and
heated mirrors are automatically
disabled when the power convertible
top is moving or down.
Caution
Using a razor blade or sharp
object on the inside rear window
can damage the antenna or
defogger. Repairs would not be
covered by the vehicle warranty.
Do not stick anything to the rear
window.
z/{: If equipped, press to heat
or ventilate the seat. See Heated
and Ventilated Front Seats 064. Remote Start Climate Control
Operation (If Equipped) :
If remote
start is used to start the vehicle, the
climate control system will come on.
The system uses the driver ’s
previous settings to heat or cool the
inside of the vehicle. The rear
window defogger or heated outside
mirrors, if equipped, may come on
based on cold ambient conditions.
The rear defog indicator light may
not come on during a remote start.
The heated or ventilated seats may
turn on if it is cold or hot outside.
See Remote Vehicle Start 034 and
Heated and Ventilated Front Seats
0 64, if equipped.
Sensors
The interior cabin air temperature
and solar sensor on top of the
instrument panel near the
windshield monitors the solar heat
and measures the initial interior
cabin temperature. The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
The humidity and windshield
temperature sensor is on the
windshield glass inside surface near
the rearview mirror. The automatic
climate control system uses this
sensor to receive information to
determine the need for defogging.
If any of these sensors are blocked
or covered, the automatic climate
control system may not work
properly.
There is also a sensor behind the
front bumper. This sensor reads the
outside air temperature and helps to
maintain the temperature inside the
vehicle. Any cover on the front of
the vehicle could give a false
reading in the temperature.

3. Remove the filter and installthe new air filter.
4. Replace the filter cover.
5. Attach the retainer clips.
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.

172 Driving and Operating
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
. Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0196.
. 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) 0193. .
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 0325. 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

184 Driving and Operating
Active Fuel Management
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual
transmission, the system is only
active in Eco Mode. With an
automatic transmission, the system
is available in all modes, but is more
aggressive in Eco Mode. SeeDriver
Mode Control 0198.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running,
be sure it will not move and there is
adequate ventilation. See Shifting
Into Park 0182 andEngine Exhaust
0 184.
If the vehicle is left parked and
running with the RKE transmitter
outside the vehicle, it will turn off
after one hour.
If the vehicle is left parked and
running with the RKE transmitter
inside the vehicle, it will turn off after
two hours.
The vehicle could turn off sooner if it
is parked on a hill, due to lack of
available fuel.
Automatic Transmission
The timer will reset if the vehicle is
shifted out of P (Park) while it is
running.
Manual Transmission
The timer will reset if the vehicle
speed is greater than 4 km/h
(2.5 mph).
Engine Exhaust
{Warning
Engine exhaust contains carbon
monoxide (CO), which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if: . The vehicle idles in areas
with poor ventilation
(parking garages, tunnels,
deep snow that may block
underbody airflow or tail
pipes).
. The exhaust smells or
sounds strange or different.
. The exhaust system leaks
due to corrosion or damage.
. The vehicle exhaust system
has been modified,
damaged, or improperly
repaired.
