Each remote keyless entry transmitter is uniquely coded
to prevent another transmitter from unlocking your
vehicle. If a transmitter is lost or stolen, a replacement
can be purchased through your dealer. Remember
to bring any additional transmitters so they also can be
re-coded to match the new transmitter. Once your
dealer has coded the new transmitter, the lost
transmitter cannot unlock the vehicle. The vehicle can
have a maximum of four transmitters coded to it.

VENT (Ventilation):This mode brings in outside air
and directs it through the instrument panel outlets.
BI-LEV (Bi-Level):This mode directs approximately
half of the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets.
Some air may be directed toward the windshield.
HTR (Heater):This mode directs most of the air to the
oor outlets, with some air directed to the outboard
outlets, for the side windows, and some air directed to
the windshield.
BLEND:This mode directs half of the air to go to the
oor outlets and half to the defroster and side window
outlets. The air-conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40°F (4°C).
The right knob can also be used for the defrost mode.
Information on defrosting and defogging can be
found later in this section.
9FAN:The left knob controls the fan speed.
OFF:Turn the knob all the way counterclockwise to
turn off the fan.
LO (Low Fan Speed):This setting creates the lowest
fan speed.HI (High Fan Speed):This setting creates the highest
fan speed.
DRIVER (Driver’s Side Temperature):The lever on
the left adjusts the air temperature for the driver’s
side outlets. Slide the lever up to raise the temperature
and down to lower the temperature.
PASSENGER (Passenger’s Side Temperature):The
lever on the right adjusts the air temperature for the
passenger’s side outlets. Slide the lever up to raise the
temperature and down to lower the temperature.
"(Air Conditioning):Press this button to turn the
air-conditioning on and off. An indicator light above the
button will come on when the air conditioning is on.
During daylight hours the interior lighting control might
need adjustment to the highest setting in order for the
indicator light to be seen. The system will cool and
dehumidify the air inside the vehicle when the A/C
indicator light is on.
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a quick cool-down on a very hot day, use MAX with
the temperature levers all the way in the blue area. If this
setting is used for long periods of time, the air in the
vehicle may become too dry.
For normal cooling on hot days, use VENT with the
temperature levers in the blue area. The system will bring
in outside air and cool it.

2. Press the AUTO button.
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster.
If the system is set at the warmest temperature
setting, 90°F (32°C), hot air will be directed to the
oor, the fan will increase to the highest speed, and
the system will remain in manual mode at that
temperature. The system will not return to automatic
until the temperature setting is lowered.
If the system is set at the coldest temperature
setting, 60°F (15°C), cold interior air will be
recirculated through the air panel outlets, and the
fan will increase to the highest speed. The
system will not return to automatic until the
temperature is raised.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into the vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since the vehicle was last driven.3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then, adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center
of the instrument panel, near the windshield. For
more information on the solar sensor, see
“Solar Sensor” later in this section.
Manual Operation
During daylight hours, the instrument panel brightness
control might need to be adjusted to the highest setting,
in order to see the indicator lights for the various
climate control settings.
OFF:Pressing the OFF button cancels automatic
operation and places the system in manual mode. Press
the AUTO button to return to automatic operation.
TEMP (Temperature):To manually adjust the
temperature inside the vehicle, press the up arrow on
the TEMP control to raise the temperature and press the
down arrow to lower the temperature. The display will
show the selection for a few seconds, and then the
outside temperature will be displayed.
When the DUAL light indicator is on, this means the
TEMP control has set the temperature for the driver.
When the DUAL light indicator light is not on, this means
the TEMP control has set the temperature for the
entire cabin.

Speedometer and Odometer
The speedometer shows the vehicle’s speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven in either miles (used in the United States) or in
kilometers (used in Canada).
The vehicle has a tamper-resistant odometer. If ERROR
is displayed, this indicates someone has probably
tampered with it and the numbers may not be accurate.
You may wonder what happens if the vehicle needs
a new odometer installed. If the new one can be set to
the mileage total of the old odometer, then that will
be done. But if it cannot, then it will be set at zero and a
label must be put on the driver’s door to show the old
mileage reading when the new odometer was installed.
Trip Odometer
The trip odometer tells how far the vehicle has been
driven since it was last reset. To set the trip odometer to
zero, press the button on the right side of the instrument
panel cluster.
The trip/select reset button will go back and forth
between the odometer and the trip odometer if the
button is pressed and released within 1.5 seconds.
If the button is pressed and held for longer than
1.5 seconds while in the trip odometer mode, it will be
reset to zero. If the button is pressed and held for longer
than 1.5 seconds while in the odometer mode, it will
have no effect.
