Climate Controls
Automatic Climate Control System
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has a
¯ow-through ventilation system described later in this
section.
You can select different climate control settings for the
driver and passengers.
Driver's Side Temperature Knob
The driver's side knob is used to adjust the temperature
of the air coming through the system on the driver's
side. The temperature can be adjusted even if the
system is turned off. This is possible since outside airwill always ¯ow through the system as the vehicle is
moving forward unless it is set to recirculation mode.
See ªRecirculationº later in this section.
Turn the knob counterclockwise or clockwise to lower or
increase the cabin temperature. The display will show
the temperature setting decreasing or increasing and
an arrow pointing to the driver will be displayed
under and to the left of the temperature setting.
Passenger's Side Temperature Knob
The passenger's side knob can be used to change
the temperature of the air coming through the system
on the passenger's side of the vehicle. The temperature
can be adjusted even if the system is turned off.
This is possible since outside air will always ¯ow through
the system as the vehicle is moving forward unless it
is set to recirculation mode. See ªRecirculationº later in
this section.
Turn the knob counterclockwise or clockwise to lower or
increase the cabin temperature. The display will show
the temperature setting decreasing or increasing and
an arrow pointing to the passenger will be displayed
under and to the right of the temperature setting.
The passenger's temperature setting can be set to
match the driver's temperature setting by pressing and
holding the AUTO button for four seconds. Both the
driver and passenger arrows will be displayed.

Air Conditioning
#
(Air Conditioning):Press this button to turn the air
conditioning (A/C) compressor on and off. The snow¯ake
symbol will appear on the display when the A/C is on.
When air conditioning is selected or in AUTO mode, the
system will run the air conditioning automatically to cool
and dehumidify the air entering the vehicle. If you select
A/C off while in front defrost, defog or recirculation,
the A/C snow¯ake symbol will turn off, but the A/C
compressor will still run to help prevent fogging.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for
your vehicle to cool down. Then keep your windows
closed for the air conditioner to work its best.
On cool, but sunny days while using manual operation of
the automatic system, use bi-level to deliver warm air to
the ¯oor and cooler air to the instrument panel outlets.
To warm or cool the air delivered, turn the temperature
knob to the desired setting.
In AUTO mode the system will cool and dehumidify the
air inside the vehicle. Also while in AUTO mode, the
system will maximize its performance by using
recirculation as necessary.
^(Air Conditioning Off):On some vehicles, when
you turn the air conditioning off, this symbol will appear
on the display. If your vehicle does not have this
symbol, the snow¯ake symbol will turn off to let you
know the air conditioning is off.
Heating
On cold days when using manual operation of the
automatic system, choose ¯oor mode to deliver air to
the ¯oor outlets. To warm or cool the air delivered,
turn the temperature knob to the desired setting.
If you want to use the automatic mode, press AUTO
and adjust the temperature by turning the temperature
knob.
The heater works best if you keep the windows closed
while using it.
3-28

Outlet Adjustment
Use the air outlets located in the center and on the side
of your instrument panel to direct the air¯ow.
Your vehicle has air outlets that allow you to adjust the
direction and amount of air¯ow inside the vehicle.
Move the louvers up or down. Use the thumbwheel
next to or underneath the outlet to close the louvers.
For the most efficient air¯ow and temperature control,
keep the outlet in the fully opened position.
Operation Tips
·
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
·Keep the air path under the front seats clear
of objects. This helps air to circulate throughout your
vehicle.
·Adding outside equipment to the front of your
vehicle, such as hood-air de¯ectors, etc., may affect
the performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
Climate Controls Personalization
You can store and recall the climate control settings for
temperature, air delivery mode and fan speed for
two different drivers. The personal choice settings
recalled are determined by the transmitter used to enter
the vehicle.
After the button with the unlock symbol on a remote
keyless entry transmitter is pressed, the climate control
will adjust to the last settings of the identi®ed driver.
The settings can also be changed by pressing one of the
memory buttons (1 or 2) located on the driver's door.
When adjustments are made, the new settings are
automatically saved for that driver.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210ÉF (100ÉC) or less. If you are pulling a load
or going up hills, it is normal for the temperature to
¯uctuate and approach the 250ÉF (122ÉC) mark. If the
gage reaches the 260ÉF (125ÉC) mark, it indicates
that the cooling system is working beyond its capacity.
See
Engine Overheating on page 5-27.
Transmission Temperature Gage
Your vehicle is equipped with a transmission
temperature gage.
When your ignition is on, the gage shows the temperature
of the transmission ¯uid. The normal operating range is
from 100ÉF (38ÉC) to about 265ÉF (130ÉC). United States
