Air Delivery Mode Control :Turn
clockwise or counterclockwise to
change the current airflow mode.
By positioning the right knob
between two modes, a combination
of those two modes is selected.
H(Vent) : Air is directed to the
instrument panel outlets.
)(Bi-Level) : Air is divided
between the instrument panel and
floor outlets. Some air is directed
toward the windshield and side
window outlets. Cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
6(Floor) : Air is directed to the
floor outlets, with some of the air
directed to the windshield, side
window, and second row floor
outlets. In this mode, the system
automatically selects outside air.
Recirculation cannot be selected
while in floor mode.
-(Defog) : This clears the
windows of fog or moisture. Air is
directed to the windshield, floor
outlets, and side window vents.
When this mode is selected, the system turns off recirculation and
runs the air conditioning unless the
outside temperature is less than 4 °
C (40 °F). Recirculation cannot be
selected while in the defog mode.
Do not drive the vehicle until all the
windows are clear.
0(Defrost) :
This clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield and side window vents,
with some to the floor vents. In this
mode, outside air is pulled inside
the vehicle. Recirculation cannot be
selected while in the defrost mode.
The air conditioning system runs
automatically in this setting, unless
the outside temperature is less than
4 °C (40 °F). Do not drive the
vehicle until all windows are clear.
#(Air Conditioning) : Press to
turn the air conditioning system on
or off. An indicator light comes on
when A/C is on. The air conditioning
system does not operate when the
outside temperature is below 4 °C
(40 °F). The indicator light flashes
three times and turns off when outside conditions affect air
conditioning operation. This is
normal.
For quicker cool down on hot days:
1. Open the windows to let hot air escape.
2. Select
Hmode.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
6. Close the windows after the hot air has escaped.
7. Once the vehicle's interior temperature is below the
outside temperature, select
@mode for faster cooling.
Using recirculation for long periods
of time could cause the air inside
the vehicle to become too dry. To
prevent this from happening, after
the inside of the vehicle has cooled,
turn the recirculation mode off.

about 20 minutes for the
system to regulate. Use the
driver side or passenger side
temperature control to adjust
the temperature setting as
necessary. The system will
remain at the selected setting.
Choosing the warmest or
coolest temperatures does not
cause the vehicle to heat or
cool more quickly.

cold weather, the system
delays turning on the fan until
warm air is available. Turn the
fan knob to override this delay
and select the fan speed. Temperature Control
The driver and passenger side
temperature controls are used to
adjust the temperature of the air
coming through the system. The
temperature can be adjusted even if
the system is turned off since
outside air still enters the vehicle,
unless the recirculation mode is
selected. See
“Recirculation” later in
this section.

232 Driving and Operating
To remove the fuel cap, turn it
slowly counterclockwise. The fuel
cap has a spring in it; if the cap is
released too soon, it will spring back
to the right.
While refueling, hang the fuel cap
from the hook on the fuel door.
{Warning
Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:. Vehicle performance issues,
including engine stalling and
damage to the fuel system.
. Fuel spills.
. Potential fuel fires.
Be careful not to spill fuel. Wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care 0311.
When replacing the fuel cap, turn it
clockwise until it clicks. Make sure
the cap is fully installed. If the cap is not properly installed, the
malfunction indicator lamp may
come on. See
Malfunction Indicator
Lamp (Check Engine Light) 0117.
{Warning
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Caution
If a new fuel cap is needed, be
sure to get the right type of cap
from your dealer. The wrong type
of fuel cap may not fit properly,
may cause the malfunction
indicator lamp to light, and could
damage the fuel tank and
emissions system. See
Malfunction Indicator Lamp
(Check Engine Light) 0117.
Filling a Portable Fuel
Container
{Warning

including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.
If coolant is needed, add the proper
mixture directly to the radiator, but
be sure the cooling system is cool
before this is done. Then check the
recovery tank and add coolant if
needed.
1. Detach the fasteners and lift off the panel that covers the
radiator cap.
2. Remove the radiator pressurecap when the cooling system,
including the upper radiator
hose, is no longer hot. Turn the
pressure cap slowly
counterclockwise about one
full turn.
If a hiss is heard, wait for that
to stop. A hiss means there is
still some pressure left in the
system.
3. Keep turning the pressure cap slowly and remove it.
4. Fill the radiator to the base of the filler neck with the proper
DEX-COOL coolant mixture.
5. Fill the coolant recovery tank tothe FULL COLD mark or to the
FULL COLD ISO symbol mark.
