Vehicle Damage Warnings
Also, in this book you will find these notices:
Notice: These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in different
words.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specific component, control,
message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator reference the following
topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3
Warning Lights, Gages and Indicators in Section 3
Audio System(s) in Section 3

the mounting brackets before closing the doors.
It can be dangerous to drive with the rear
glass open because carbon monoxide (CO)
gas can come into your vehicle. You can’t see
or smell CO.
It can cause unconsciousness
and even death. If you must drive with the rear
glass open or if electrical wiring or other cable
connections must pass through the seal between the body and the rear glass:

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 airflow inside of your vehicle. To change
the current mode, select one of the following:
+2 (Bi-Level): This mode directs approximately half
of the air to the instrument panel outlets and directs
most of the remaining air to the floor outlets. Some air
may be directed toward the windshield.
;$’ (Vent): This mode directs air to the instrument
panel outlets.
(Floor): This mode directs most of the air to the
floor 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 dehumidifies 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.
@ (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.

Defogging and Defrosting
Turn the right knob to select the defog or defrost mode.
+3 (Blend): With this setting, the outside air comes
out
of both the floor 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.
9 (Defrost): This setting operates the defroster.
Most of the air comes out near the windshield, with
some going to the floor 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 Heating System
Your vehicle may have an optional rear heating system
that allows you to adjust the amount of air flowing
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 an optional 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.
Directing the Airflow
To direct the airflow 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 floor outlets are used for heating.
Selecting the Fan Speed
Rear Heat and Rear A/C
8f? (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.
