Driver Information System
This system displays the outside air temperature,
compass direction and trip information in the overhead
console.
US/MET (United States/Metric):The US/MET button
allows you to switch the display between the English and
metric system.
MODE:The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.COMP/TEMP (Compass/Temperature):This display
provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle is
facing.
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the outside
temperature is 37°F (3°C) or lower, the display will
toggle between the word ICE and the current
temperature every eight seconds. This is a warning to
the driver that road conditions may be icy, and that
appropriate precautions should be taken.
The compass is self-calibrating, so it does not need to
be manually set. However, if C (Calibration) is displayed,
the compass will need to be calibrated. You may also
place the compass in a noncalibrated mode by pressing
and holding the US/MET and MODE buttons
simultaneously while in the COMP/TEMP mode. After
about 10 seconds, the compass will display C and
you can release the buttons. Drive the vehicle in
a complete 360° circle three times at a speed of less
than 5 mph (8 km/h), and the compass will function
normally. Once the calibration is complete, the display
will return to a compass reading.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.To change the current mode, select one of the following:
)(Bi-Level):This mode directs approximately half
of the air to the instrument panel outlets and directs
most of the remaining air to the oor outlets. Some air
may be directed toward the windshield.
H(Vent):This mode directs air to the instrument
panel outlets.
6(Floor):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.
A/C (Air Conditioning):This setting brings in outside
air, cools and dehumidies it.
MAX A/C (Maximum Air Conditioning):This setting
cools the air the fastest, by recirculating the inside air.
The right knob can also be used to select the defrost
mode. Information on defogging and defrosting can be
found later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.
3-18

Defogging and Defrosting
Turn the right knob to select the defog or defrost mode.
-(Blend):With this setting, the outside air comes
out of both the oor and defroster outlets. Adjust
the temperature knob for warmer or cooler air. The air
conditioning compressor may operate in this setting
to dehumidfy the air.
1(Defrost):This setting operates the defroster. Most
of the air comes out near the windshield, with some
going to the oor outlets and front side windows. The air
conditioning compressor may operate in this setting to
dehumidify the air.
The bi-level setting is useful for cold weather with a
large number of passengers or very humid conditions to
help keep the windshield clear. Use defrost to remove
fog or ice from the windshield quickly in extremely
cold conditions. The temperature knob should be in the
red area and the fan control toward high.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in RUN.Press this button to turn
the rear window defogger
on or off. Be sure to
clear as much snow from
the window as possible.
The rear window defogger will turn off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.

Rear Heating System
Your vehicle may have a rear heating system that
allows you to adjust the amount of air owing into the
rear of the vehicle, from the front-seating area. This
feature works with the main climate-control system in
your vehicle.
The thumbwheel for this system is located to the right of
the audio system.
Turn the thumbwheel up or down to increase or
decrease the amount of heated air sent to the
rear-seating area.
Rear Air Conditioning System
Your vehicle may have a rear air-conditioning system
that allows you to adjust the fan speed in the
rear-seating area, from the front-seating area. This
feature works with the main climate-control system in
your vehicle.
The thumbwheel for this system is located to the right of
the rear-heating system.
Turn the thumbwheel up or down to increase or
decrease the amount of cooled air sent to the
rear-seating area.
3-21

Directing the Airow
To direct the airow to the rear-seating area, use the
right knob located on the main climate-control panel.
Generally the upper outlets are used for air conditioning
and the oor outlets are used for heating.
Selecting the Fan Speed
Rear Heat and Rear A/C
9(Fan):Move either thumbwheel on either climate
control panel up or down to HIGH, MED (Medium)
or LOW to increase or decrease the fan speed in the
rear-seating area. Move the thumbwheel to OFF to turn
off the fan.
Setting the Temperature
To increase or decrease the temperature for the entire
vehicle use the center knob located on the main
climate-control panel.
The air-conditioning system on the main climate-control
panel must be turned on to direct cooled air to the
rear of the vehicle. If it is not on, then the temperature
in the rear of the vehicle will remain at cabin
temperature.
Be sure to keep the area under the front seats clear of
any objects so that the air inside of your vehicle can
circulate effectively.
For information on how to use the main climate-control
system. For information on ventilation, see “Outlet
Adjustment” earlier in this section.
