Automatic Temperature Control — If Equipped
Automatic Operation
The Infrared Dual-Zone Climate Control System auto-
matically maintains the climate in the cabin of the vehicle
at the comfort levels desired by the driver and passenger.
To accomplish this, the system gathers information fromthe controls on the climate control, from a dual sun-
sensor located in the top of the instrument panel, from an
infrared sensor located in the face of the climate control,
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. The dual sun-sensor monitors sun
load coming through the windshield. The infrared sensor
independently measures the surface temperature of the
driver and passenger. Other sensors take into account
vehicle-speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple. Begin by turning
the mode control knob (on the right) to AUTO, and place
the blower control knob (on the left) to either LO AUTO

conditioning. An indicator in the button illuminates
when manual compressor operation is selected.
NOTE:To control the air conditioning manually, the
mode selector must be moved out of the AUTO position.
•Recirculation Control
This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The Recirculation mode should only
be used temporarily. An indicator in the button
illuminates when the Recirculation mode is active. You
may use this feature separately.
NOTE:Extended use of recirculation may cause the
windows to fog. If the interior of the windows begins to
fog, press the recirculation button to return to outside air.
Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper visibil-
ity. For this reason, the system will not allow recirculation
to be selected while in Defrost or Defrost/Floor mode.Attempting to use the recirculation while in these modes
will cause the indicator in the control button to blink and
then turn off.
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 in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to “Maintenance Procedures” in Section 7 for proper
coolant selection.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Do not leave the key in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
•Do not leave animals or children inside parked
vehicles in hot weather; interior heat buildup may
cause serious injury or death.
(Continued)
WARNING! (Continued)
•Be sure to turn OFF the engine and remove the key
from the ignition switch if you want to rest or
sleep in your car. Accidents can be caused by
inadvertently moving the shift lever. Accidents
can also be caused by pressing the accelerator
pedal. This may cause excessive heat in the ex-
haust system, resulting in overheating and vehicle
fire, which may cause serious or fatal injuries.
Automatic Transmission
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.

CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
Keyless Go (If Equipped)
This function allows the driver to op-
erate the ignition switch with the push
of a button, as long as the ENGINE
START/STOP button is installed and
the Keyless Go ignition key (FOBIK)
can be detected inside of the vehicle.
Removing and Re-Installing the Engine Start/Stop
Button
The ENGINE START/STOP button may be removed
from the receptacle to allow the vehicle ignition to be
controlled conventionally by inserting the FOBIK. The
button may be removed using the valet key from the
FOBIK as a thin tool. Insert the metal part of the valet key
under the chrome bezel at the 6 o’clock position, and
gently pry the button loose.
314 STARTING AND OPERATING

To reinstall the button, position it with its lettering
oriented horizontal and readable. Gently insert the but-
ton into the receptacle by pressing on the center of the
button. If the button slips in easily, it has been installed
correctly. Press firmly on the center of the button to seat
the button into the receptacle.
The ENGINE START/STOP button should only be re-
moved or inserted with the ignition in the OFF position.
Keyless Go Functions — With Driver ’s Foot Off
The Brake Pedal (In PARK Position)
•
Press the ENGINE START/STOP buttononce (ACC
position)to activate the radio, wipers, and windows.
•Press the ENGINE START/STOP buttontwice (ON
position)to activate the heating/air conditioning
(HVAC) controls, and the instrument cluster.
•Press the ENGINE START/STOP buttonthree times
(OFF position)to turn off the ignition switch.
Normal Starting
Using The ENGINE START/STOP Button
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or depressing the
accelerator pedal.
To start the engine, the transmission must be in PARK or
NEUTRAL. From any ignition state, press and hold the
brake pedal while pressing the ENGINE START/STOP
button. The system takes over and attempts to start the
vehicle. If the vehicle fails to start, the starter will
disengage automatically after 10 seconds. If you wish to
stop the cranking of the engine prior to the engine
starting, press the button again.
Using Fob With Integrated Key (Tip Start)
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or depressing the
accelerator pedal.
