To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking while
the key is in the ignition and a door is open.
If a power lock switch is pressed while a door is open
and the key is in the ignition, both doors will lock
and then the driver's door will unlock. A chime will sound
continuously until both doors are closed.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door.

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling,
defrost, defog and ventilation for your vehicle.
Directing the Air¯ow
Turn the right knob clockwise or counterclockwise to
direct the air¯ow inside of your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode allows for approximately a
50/50 split of air to the instrument panel outlets and
to the ¯oor outlets.
6(Floor):This mode directs most of the air to the
¯oor outlets, with some of the air directed to the
windshield and side window outlets. In this mode, the
system will automatically select Outside Air.
The mode knob can also be used to select defog or
defrost mode. For information on defogging and
defrosting, see ªDefogging and Defrostingº later in this
section.
It should be noted, that the air conditioning compressor
will be engaged unless the outside temperature is
40É F (4ÉC) or below. Recirculation cannot be selected
when in Floor Mode.
3-22

?(Recirculation):Press this button to turn the
recirculation mode on. When this mode is on, inside air
and a small percentage of outside air will recirculate
throughout your vehicle. This selection will reduce
the entry of outside air and odors from entering your
vehicle, it may also help heat or cool your vehicle more
quickly. When this button is pressed, an indicator
light in the button will also come on to let you know that
it is activated. During daylight hours, you may have
to adjust the instrument panel brightness control to the
highest setting in order to see the indicator light.
See
Interior Lamps on page 3-17for more information.
The recirculation mode can be used with vent and
bi-level modes, but it cannot be used with ¯oor, defog,
defrost or outside air modes.
This system will default back to the outside air setting,
so you will have to re-select this setting every time
that you start the vehicle.
If the weather is cold and damp, the system may cause
the windows to fog while using the recirculation
mode. If the windows do start to fog, do the following:
1. Select the defog or defrost mode.
2. Select the temperature.
3. Select the highest fan speed.
4. Operate the system in the outside air mode, to help
prevent a recurrence.
Heating
Adjust the air temperature by using the following levers:
D (Driver):Slide this lever up or down to raise or
lower the temperature on the driver's side of the vehicle.
P (Passenger):Slide this lever up or down to raise
or lower the temperature on the passenger's side of the
vehicle.
To warm your vehicle on cold days, do the following:
1. Select the ¯oor mode.
2. Select the warmest temperature.
3. Select the fan speed.
4. Select outside air mode, after the air has warmed,
to prevent it from becoming too stale.
When it's cold outside 0ÉF (-18ÉC) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
see
Engine Coolant Heater on page 2-20.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(REAR):Press this button to turn the rear window
defogger on or off. An indicator light in the button
will come on to let you know that the rear window
defogger is activated. During daylight hours, you may
have to adjust the instrument panel brightness control to
the highest setting in order to see the indicator light.
See
Interior Lamps on page 3-17for more information.
The rear window defogger will turn off approximately
20 minutes after the button is pressed. If turned on
again, the defogger will run for the same amount of time.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
If your vehicle has heated outside rearview mirrors, the
Rear Window Defogger also warms the heated
driver's and passenger's outside rearview mirrors to
help clear them of ice, snow and condensation.
Do not drive the vehicle until all the windows are clear.
Notice:Don't use a razor blade or something
else sharp on the inside of the rear window. If you
do, you could cut or damage the defogger and
the repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape,
a decal or anything similar to the defogger grid.
Outlet Adjustment
The ¯ow through ventilation system on your vehicle
allows outside air to enter your vehicle when it is moving.
Outside air will also enter your vehicle when the
air-conditioning compressor is running and even in small
amounts when the recirculation mode is activated.
Use the control located
below or to the side of the
vent, to change the
direction of the air ¯owing
through them or to shut
them off.
For mild outside temperatures when little heating or
cooling is needed, do the following:
1. Select the vent mode.
2. Select outside air mode.
3. Select the temperature.
4. Select the fan speed.

Ventilation Tips
·
Clear away any ice, snow or leaves from the air
inlets on the hood that may block the ¯ow of air
into your vehicle. This will help to remove fog
or frost from the windows it will also improve
heating.
·Select the ¯oor mode and set the fan at the highest
speed when ®rst starting your vehicle to help clear
the air intake ducts of moisture or snow. This
will also help to remove fog from the windows.
·Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air ®lter. It is located
underneath the hood just below the windshield wiper
arm on the passenger's side of the vehicle, underneath
the air inlet grille.
The ®lter traps most of the pollen from air entering the
Climate Control System. Like your engine's air
cleaner/®lter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
®lter, see
Scheduled Maintenance on page 6-5.

Engine Coolant Temperature GageThis gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During the 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. When the gage reads greater than 250ÉF
(122ÉC), the HOT COOLANT TEMP light will be
illuminated in the message center and a chime will
sound continuously. If the gage reaches the 260ÉF
(125ÉC) mark, it indicates that the cooling system is
working beyond its capacity.
