NOTE:
•If the RECIRCULATION button is pushed when the
system is in Defrost mode, the Recirculation LED
indicator will flash three times and then turn off to
indicate Recirculation mode is not allowed.
•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•In cold or damp weather, the use of the Recirculation
mode will cause windows to fog on the inside because
of moisture buildup inside the vehicle. For maximum
defogging, select the outside air position.
•The A/C can be deselected manually without disturb-
ing the mode control selection by pushing the A/C
button.
Air Outlets
The airflow from each of the instrument panel outlets can be
adjusted for direction, and turned on or off to control airflow.
NOTE:For maximum airflow to the rear, the center
instrument panel outlets can be directed toward the rear
seat passengers.
Economy Mode
If ECONOMY mode is desired, push the A/C button to
turn off the LED indicator and the A/C compressor.

To provide you with maximum comfort in the Automatic
mode, during cold start-ups the blower fan will remain
on low until the engine warms up. The blower will
increase in speed and transition into Auto mode.
Manual Operation Override
The system allows for manual selection of blower speed,
air distribution mode, A/C status and recirculation control.
The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.
The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
NOTE:Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS-12106) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.

Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant selection.
Use of the air Recirculation mode during Winter months is
not recommended because it may cause window fogging.
Vacation/Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in
fresh air with the blower setting in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost on
the inside of the glass in very cold weather. To clear the
windows, select Defrost or Mix mode and increase the front
blower speed. Do not use the Recirculation mode without
A/C for long periods, as fogging may occur.
NOTE:Automatic Temperature Controls (ATC) will au-
tomatically adjust the climate control settings to reduce
or eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, can cause
odor, and if they enter the plenum they could plug the
water drains. In winter months, ensure the air intake is
clear of ice, slush and snow.

ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three positions, OFF, ACC, RUN.
To change the ignition switch positions without starting
the vehicle and use the accessories follow these steps:
1. Starting with the ignition in the OFF position:
2. Press the ENGINE START/STOP button once to
change the ignition to the ACC position.
3. Press the ENGINE START/STOP button a second time
to change the ignition to the RUN position.
4. Press the ENGINE START/STOP button a third time
to return the ignition to the OFF position.
Extreme Cold Weather (Below –20°F Or−29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while cranking the engine. This should clear any
excess fuel in case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 10 seconds at a time. Wait 10 to
15 seconds before trying again.

WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
•If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the igni-
tion button/key is released. If this occurs, continue
cranking with the accelerator pedal pushed all the way to
the floor. Release the accelerator pedal and the ignition
button/key once the engine is running smoothly.
If the engine shows no sign of starting after two 10-
second periods of cranking with the accelerator pedal
held to the floor, the “Normal Starting” procedure should
be repeated.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
