Front Blower Control
There are four blower speeds. Use this
control to regulate the amount of air
forced through the system in any
mode you select. The blower speed
increases as you move the control
clockwise from the OFF position.
NOTE: For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the blower control is left in the OFF position.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the knob coun-
terclockwise, from top center into the
blue area of the scale, indicates cooler
temperatures. Rotating the knob clock-
wise, into the red area, indicates
warmer temperatures.
NOTE: If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser (located in front of the radiator), for an accumu-
lation of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.

cold or snowy conditions that require extra heat at the
windshield. This setting is good for maintaining comfort,
while reducing moisture on the windshield.
Defrost Mode
Air is directed through the windshield and side
window demist outlets. Use the DEFROST mode
with maximum blower and warm temperature settings
for best windshield and side window defrosting.
NOTE: The air conditioning compressor operates in MIX
and DEFROST, or a blend of these modes even if the A/C
button is not pressed. This dehumidifies the air to help
dry the windshield. To improve fuel economy, use these
modes only when necessary.
Recirculation Control
Press this button to choose between outside air
intake or recirculation of the air inside the
vehicle. A LED will illuminate when you are in
Recirculation mode. Only use the Recirculation
mode to temporarily block out any outside odors, smoke,
or dust, and to cool the interior rapidly upon initial
start-up in very hot or humid weather.
NOTE:
• If the RECIRCULATION button is pressed 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.

•Panel Mode
Air comes from the outlets in the instrument
panel. Each of these outlets can be individually
adjusted to direct the flow of air. The air vanes of
the center outlets and outboard outlets can be moved up
and down or side to side to regulate airflow direction.
There is a shut off wheel located below the air vanes to
shut off or adjust the amount of airflow from these
outlets.
• Bi-Level Mode
Air comes from the instrument panel outlets and
floor outlets. A slight amount of air is directed
through the defrost and side window demister
outlets.
NOTE: BI-LEVEL mode is designed under comfort con-
ditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets. •
Floor Mode
Air comes from the floor outlets. A slight amount
of air is directed through the defrost and side
window demister outlets.
• Mix Mode
Air comes from the floor, defrost and side window
demister outlets. This mode works best in cold or
snowy conditions.
6. Blower Control
Blower control is used to regulate the amount of air forced
through the climate system. There are seven blower speeds
available. Adjusting the blower will cause automatic mode
to switch to manual operation. The speeds can be selected
using either hard-keys or soft-keys as follows:
Hard-key
The blower speed increases as you turn the control
clockwise from the lowest blower setting. The blower
speed decreases as you turn the knob counter-clockwise.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 15-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the shift
lever. Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do not
(Continued)
WARNING!(Continued)
leave a vehicle equipped with Keyless Enter-N-Go™
(if equipped) in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Turn the key fob to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key fob to the OFF position, wait five
seconds, then repeat the “Normal Starting” procedure.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting into any
driving range.
