MANUAL HEATING AND AIR CONDITIONING SYSTEM
(IF EQUIPPED)
1.
Fan speed adjustment:Turn to select fan speed.
2.
RRear defroster:Press to activate/deactivate the rear window
defroster. Refer toRear window defrosterlater in this chapter for more
information.
3.
Defrost:Distributes outside air through the windshield defroster
vents and demister vents. Can be used to clear the windshield of fog and
thin ice. The system will automatically provide outside air to reduce
window fogging. Press this button again to return to the previous air flow
selection.
4.
:Distributes air through the windshield defroster vents, demister
vents, floor vents and rear seat floor vents. The system will automatically
provide outside air to reduce window fogging.
5.
Power:Press to activate/deactivate the climate control system.
When the system is off, outside air is prevented from entering the
vehicle through the vents.
6.
:Distributes air through the instrument panel vents.
7.
:Distributes air through the instrument panel vents, demister
vents, floor vents and rear seat floor vents (if equipped).
8.
:Distributes air through the demister vents, floor vents and rear
seat floor vents (if equipped).

9.Temperature control:Controls the temperature of the airflow in the
vehicle.
10.
Passenger heated seat control (if equipped):Press to
activate/deactivate the passenger heated seat. SeeHeated seatsin the
Seating and Safety Restraintschapter.
11.
Recirculated air:Press to activate/deactivate air recirculation
in the vehicle. Recirculated air may reduce the amount of time needed to
cool down the interior of the vehicle and may also help reduce undesired
odors from reaching the interior of the vehicle. Recirculated air engages
automatically when MAX A/C is selected or can be engaged manually in
any airflow mode except
(defrost). Recirculated air may turn off
automatically in all airflow modes except MAX A/C. When the ignition
switch is turned off and back on, the climate system will return to the
recirculated air mode only if the A/C button LED is illuminated and the
air distribution selection is either
(panel) or(panel/floor).
Recirculation may turn off automatically in some airflow modes to reduce
fog potential.
12.MAX A/C:Distributes recirculated air through the instrument panel
vents to cool the vehicle. This re-cooling of the interior air is more
economical and efficient. Recirculated air may also help reduce
undesirable odors from entering the vehicle. Press the MAX A/C button
again for normal A/C operation.
13.A/C:Press to activate/deactivate air conditioning. Use with
recirculated air to improve cooling performance and efficiency. Engages
automatically in MAX A/C,
(defrost) and(floor/defrost).
14.
Driver heated seat control (if equipped):Press to
activate/deactivate the driver heated seat. SeeHeated seatsin the
Seating and Safety Restraintschapter.
Outside temperature (if equipped):The outside temperature will
appear in the display and is labeled EXT TEMP. To change the display
between Fahrenheit and Celsius, seeMessage centerin theInstrument
Clusterchapter.
Operating tips
•To reduce fog build up on the windshield during humid weather,
select
(defrost) or(floor/defrost).
•To reduce humidity build up inside the vehicle, do not drive with the
system off or with
(recirculated air) engaged and A/C off.

initial setting is between 72°F (22°C) and 75°F (24°C), then adjust for
comfort. The passenger side temperature setting will appear in the upper
right corner of the display.

5. Continue to press the RESET
control until the correct zone
appears in the center stack display.
6. The direction will display after
the RESET control is released. The

Compass calibration adjustment
Perform compass calibration in an open area free from steel structures
and high voltage lines. For optimum calibration, turn off all electrical
accessories (heater/air conditioning, wipers, etc.) and make sure all
vehicle doors are shut.
1. Start the vehicle.
2. To calibrate, press and hold the
RESET control for approximately
ten seconds until CAL appears.
Release the control.
3. Slowly drive the vehicle in a
circle (less than 3 mph [5 km/h]) until the CAL display changes to the
direction value. It may take up to five circles to complete calibration.
4. The compass is now calibrated.

Do not use starting fluid such as ether in the air intake system. Such
fluid could cause immediate explosive damage to the engine and possible
personal injury.
If you should experience cold weather starting problems on E
85ethanol,
and neither an alternative brand of E
85ethanol nor an engine block
heater is available, the addition of unleaded gasoline to your tank will
improve cold starting performance. Your vehicle is designed to operate
on E
85ethanol alone, unleaded gasoline alone, or any mixture of the two.
SeeChoosing the right fuelin theMaintenance and Specifications
chapter for more information on ethanol.
If the engine fails to start using the preceding instructions
(flexible fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 1 inch (2.5 cm) or adjust the heating or
air conditioning to bring in fresh air.
ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).

When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
WARNING:Fail-safe mode is for use during emergencies only.
Operate the vehicle in fail-safe mode only as long as necessary to
bring the vehicle to rest in a safe location and seek immediate repairs.
When in fail-safe mode, the vehicle will have limited power, will not be
able to maintain high-speed operation, and may completely shut down
without warning, potentially losing engine power, power steering assist,
and power brake assist, which may increase the possibility of a crash
resulting in serious injury.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
5. Re-start the engine and take your vehicle to an authorized dealer.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to an
authorized dealer as soon as possible.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter that is integrated with
the fuel tank. Regular maintenance or replacement is not needed.
