Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are. If
you cut too sharply into the right lane, you could hit
a vehicle on the right. Check the inside mirror or
glance over your shoulder before changing lanes.
The passenger side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver seat.

E. Outside Air
F. Recirculation
G. Rear Window
DefoggerTemperature Control:Turn clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle.
9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. Turn the
knob all the way counterclockwise to turn the front
system off.
Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the direction of the airow
inside the vehicle. The knob can be positioned between
two modes to select a combination of those modes.
Select from the following:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the instrument
panel and oor outlets.
6(Floor):Air is directed to the oor outlets, with
some air directed to the windshield and side window
outlets. In this mode, the system automatically
selects outside air. Recirculation cannot be selected
in oor mode.
3-24

-(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield, oor outlets,
and side window vents.
0(Defrost):This mode removes fog or frost from
the windshield more quickly. Air is directed to the
windshield and the side window vents, with some air
directed to the oor vents. The system automatically
forces outside air into the vehicle.
The recirculation mode cannot be selected in the defog
or defrost mode. When either mode is selected, the
system runs the air conditioning compressor, unless the
outside temperature is close to freezing.
Do not drive the vehicle until all the windows are clear.
:(Outside Air):Press to turn the outside air
mode on. An indicator light comes on to show that
outside air is on. In this mode outside air circulates
throughout the vehicle. The outside air mode can
be used with all modes, but it cannot be used with the
recirculation mode.
?(Recirculation):Press to turn the recirculation
mode on. An indicator light comes on to show that
recirculation is on.This mode recirculates and helps to quickly cool the
air inside the vehicle. It can be used to help prevent
outside air and odors from entering the vehicle.
The recirculation mode cannot be used with oor,
defog or defrost modes. If recirculation is selected with
one of these modes, the indicator light ashes
three times and then turns off. While in recirculation
mode the windows may fog when the weather is cold
and damp. To clear the fog, select either the defog
or defrost mode and increase the fan speed.
The recirculation mode can be turned off by pressing
the outside air button, or by turning off the ignition.
#(Air Conditioning):Press to turn the air conditioning
system on or off. An indicator light comes on to show
that the air conditioning is on. The air conditioning
can be selected in any mode as long as the fan switch
is on.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.

O(On/Off):Press to turn the climate control system
on or off. Outside air still enters the vehicle, and is
directed to the oor. This direction can be changed
by pressing the mode button. Recirculation can be
selected once you have selected vent or bi-level mode.
The temperature can also be adjusted using either
temperature button. If the air delivery mode or
temperature settings are adjusted with the system off,
the display illuminates briey to show the settings
and then returns to off. The system can be turned back
on by pressing either
O,D,C,#, the defrost or
the AUTO button.
Driver and Passenger Side Temperature
Controls
The driver and passenger side temperature buttons are
used to adjust the temperature of the air coming
through the system on the driver or passenger’s side of
the vehicle. The temperature can be adjusted even if
the system is turned off. This is possible since outside
air always ows through the system as the vehicle
is moving forward unless it is set to recirculation mode.
See “Recirculation” later in this section.
3-28

Press the + or−buttons to increase or decrease the
cabin temperature. The driver side or passenger
side temperature display shows the temperature setting
decreasing or increasing.
The passenger’s temperature setting can be set to
match the driver’s temperature setting by pressing the
PASS button and turning off the PASS indicator.
When the passenger’s temperature setting is set
different than the driver’s setting, the indicator on the
PASS button illuminates and both the driver side
and passenger side temperature displays are shown.
Automatic Operation
AUTO (Automatic):When automatic operation is
active the system controls the inside temperature,
the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display changes to
show the current temperature(s) and AUTO is lit on
the display. The current air delivery mode and
fan speed are also displayed for about 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet are automatically controlled.
The air conditioning compressor may run when
the outside temperature is above freezing. The air
inlet will normally be set to outside air. If it ishot outside, the air inlet may automatically switch to
the recirculate mode to help quickly cool down
the air inside the vehicle. The light on the button
comes on in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F (23°C)
temperature setting and allow about 20 minutes
for the system to regulate. Use the driver or
passenger temperature buttons to adjust the
temperature setting as necessary. If a temperature
setting of 60°F (15°C) is chosen, the system
remains at the maximum cooling setting. If a
temperature setting of 90°F (32°C) is chosen, the
system remains at the maximum heat setting.
Choosing either maximum setting will not cause the
vehicle to heat or cool any faster.
Do not cover the solar sensor located on the top of the
instrument panel near the windshield. This sensor
regulates air temperature based on sun load. For more
information on the solar sensor, see “Sensors” later
in this section.
To avoid blowing cold air in cold weather, the system
delays turning the fan on until warm air is available.
The length of delay depends on the engine coolant
temperature. Pressing the fan switch overrides this delay
and changes the fan to a selected speed.
