The ATC system uses an infrared sensor located in the
overhead console to measure the temperature of the
driver. Based on the sensor input, the system will auto-
matically control comfort by varying the temperature, fan
speed, and mode. This maintains a comfortable tempera-
ture, even under changing conditions. It is important that
the infrared sensor is kept clean and that objects are not
blocking the sensor. It is also important that objects are
not used that may scratch or damage it in any way.
Level Of Automatic Control
72°F (22°C) is the recommended setting for maximum
comfort for the average person, however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation. It is
not necessary to move the temperature setting for cold or
hot vehicles. The system automatically adjusts the tem-
perature, mode and fan speed to provide comfort as
quickly as possible.NOTE:In cold weather, the fan will not turn on in
AUTO mode until the engine coolant has warmed up
sufficiently. This is indicated by the WARM UP DELAY
message on the display.
NOTE:The temperature can be displayed in U.S. or
Metric by selecting the US/M customer programmable
feature. Refer to theOverhead Console-Customer Pro-
grammable Features.The mode will also be shown in the
display and will change as required during automatic
operation.
NOTE:The system can be put into recirculate mode
without affecting ATC operation. This will prevent out-
side air from entering the vehicle. Use this mode to
temporarily block out any outside odors, smoke, or dust.

Manual Control (ATC)
You also may choose to customize your comfort by
selecting the fan speed and mode manually. Pressing the
fan speed button or any mode button places the system
into manual operation.
While in manual operation there are six fan speeds
available and the choice of any mode. The airflow
temperature is adjusted automatically to maintain the
desired comfort level. You can adjust the temperature by
pressing the + or – TEMP rocker switch.
FAN Control
Use this button to regulate the amount of air deliv-
ered through the system in any mode you select.
Press the + or – side of the button to increase or decrease
fan speed.
Air Conditioning Operation
Press this button to turn on the air conditioning
compressor. A snow flake symbol in the displayshows that the compressor is on. Compressor operation is
automatic when you press the AUTO button and no
snowflake is shown.
The compressor can operate at any temperature above
32°F (0°C).
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes in
engine speed or power may be noticed when the com-
pressor is on. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
Recirculate Button
Press this button to recirculate the air inside the
vehicle. Outside air is prevented from entering
the vehicle. Use this mode to temporarily block
out any outside odors, smoke, dust or when
rapid cooling of the interior is required.

Rear Rotary Blower Control
The second row seat occupants have control of the rear
blower speed, only when the front control unit is in the
“REAR CONTROL” position.
The rear blower switch has an “Off” position and a range
of blower speeds. Rotating the rear blower control clock-
wise will increase the blower speed.
Rear Rotary Temperature Control
The second row seat occupants have control of the rear
temperature control, only when the front control unit is
in the “REAR CONTROL” position.
To change the temperature in the rear of the vehicle,
rotate the temperature control knob to the right or left.
The blue area indicates cooler temperatures while the red
area indicates warmer temperatures.NOTE:For best operation, make sure that ventilation
grilles located in the rear storage area are not obstructed
by stowed articles.

WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
After Starting
The idle speed is automatically controlled on fuel injected
engines and will decrease as the engine warms up.
CAUTION!
Long periods of engine idling can cause excessive
exhaust temperatures which can damage your ve-
hicle. Do not leave your vehicle unattended with the
engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Engine Block Heater — If Equipped
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three wire extension cord.
The 3.7L/4.7L engine block heater cord is located at the
front of the engine compartment near the radiator cap.
The 5.7L engine block heater cord is located on the left
side of the engine compartment and rearward of the
power distribution center.

WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution.
AUTOMATIC TRANSMISSION
Automatic Transmission
The electronic PRNDL on the instrument cluster indicates
the transmission gear selected. The selector lever is
mounted on the right side of the steering column. To
drive, move the selector lever from Park or Neutral to the
desired drive position. Pull selector lever toward you
when shifting into Reverse, Second, First or Park, or
when shifting out of Park.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of Park and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress thebrake
pedal first,before moving the gear selector out of PARK.
Gear Ranges
DO NOT race the engine when shifting from Park or
Neutral position into another gear range.
“P” Park
Supplements parking brake by locking the transmission.
Engine can be started in this range. Never use Park while
vehicle is in motion. Apply parking brake when leaving
vehicle in this range. Always apply parking brake first,
then place selector in Park position.

the fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds of shifting from Park into
any other gear position.
FOUR-WHEEL DRIVE OPERATION
NV 144 Transfer Case Operating
Information/Precautions
The NV 144 is an electric shift transfer case and is
operated by the Four-Wheel-Drive (4WD) Control
Switch, which is located on the instrument panel.
The NV 144 transfer case provides 2 mode positions:
All-Wheel Drive (AWD) and 4-Wheel-Drive LOCK.
The NV 144 transfer case is designed to be driven in for
AWD for normal street and highway conditions (all road
surfaces roads).When additional traction is required, the transfer case
4LOCK position can be used to lock the front and rear
driveshafts together and force the front and rear wheels
to rotate at the same speed. This is accomplished by
rotating the 4WD Control Switch to the 4LOCK position
- see Shifting Procedure section for specific shifting
instructions. The 4LOCK position is designed for loose,
slippery road surfaces only. Driving in the 4LOCK posi-
tion on dry hard surfaced roads may cause increased tire
wear and damage to the driveline components.
Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster, and indicate the current and desired
transfer case selection. If there are no indicator lights on
or flashing the transfer case position is All-Wheel Drive
(AWD).
The “SVC 4WD” warning light monitors the electric shift
4WD system. If this light remains on after engine start up
