Vehicle Damage Warnings
Also, in this manual you will find these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not
be covered by your vehicle’s warranty, and it
could be costly. But the notice will tell 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.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols 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

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 132.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 256.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your vehicle when the engine is running
unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
always set the parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 129.
If you are pulling a trailer, seeTowing a Trailer on
page 269.
133

Outside Heated Mirrors
If your vehicle is
equipped with outside
heated mirrors, they
can be defrosted
by pressing the mirror
button located near
the fan control.
An indicator light in the button will light when the
outside heated mirrors are activated.
Your rear window defogger comes on when the
outside heated mirrors are on. If your vehicle has a
rear window defogger, see “Rear Window
Defogger” inClimate Control System on page 160.
Storage Areas
Your vehicle may have a front storage
compartment. It is located at the center of the
instrument panel extension, by the floor. To open
the compartment, pull up on the latch. The
compartment will open automatically.
Storage compartments may also be included on
the inside of each front door.

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:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of the
air to the instrument panel outlets, then directs
most of the remaining air to the floor outlets. Some
air may be directed toward the windshield.
6(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.
The right knob can also be used to select the
defrost and defog modes. 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.
160

If your vehicle has air conditioning, your heating/air
conditioning controls will look like this:
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
A/C (Air Conditioning):This setting will begin to
cool and dehumidify the air inside of your vehicle.
MAX A/C (Maximum Air Conditioning):Turn the
right knob to MAX A/C for maximum cooling.
This setting cools the air the fastest, by
recirculating the inside air.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control is
used properly. There are two modes to clear fog or
frost from your windshield and side windows.Use the defog mode to clear the windows of fog or
moisture and warm the passengers. Use the defrost
mode to remove fog or frost from the windshield
more quickly. For best results, clear all snow and
ice from the windshield before defrosting.
Turn the knob on the right of the climate control
panel to select the defog or defrost mode.
-(Defog):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 dehumidify the air.
1(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 defog 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. Do not drive the
vehicle until all the windows are clear.
161

Rear Heating System
Your vehicle may have a 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.
REAR HEAT:The thumbwheel for this system is
located to the left of the audio system.
9(Fan):Turn the thumbwheel up or down to
increase or decrease the amount of heated air sent
to the rear-seating area.
HI:Turn the thumbwheel to this position to supply
the most amount of heat to the rear-seating area.
LO:Turn the thumbwheel to this position to supply
the least amount of heat to the rear-seating area.
OFF:Turn the thumbwheel to this position to turn
the rear heating system off.
163

Rear Air Conditioning and
Heating System
Your vehicle may have a rear heating and
air-conditioning system. This system regulates the
temperature, the fan speed and the air delivery for
the rear-seat passengers only. It also works with
the main climate-control system in your vehicle.
Use this control panel when you would like to
maintain a separate temperature setting. Adjust the
direction of the airflow or adjust the fan speed
for the rear seat passenger(s).If your vehicle has a 135 inch (343 cm) wheelbase,
a rear control panel for this system is located in
the second row behind the driver in the rear
of your vehicle. A rear seat passenger can use
this control panel to personally adjust the
temperature, the direction of the airflow and the
fan speed for the rear seating area.
The fan knob located on the front climate control
panel must be turned to REAR CNTL to allow a rear
seat passenger to use the control panel in the rear
seating area. Performing this action disables the
front control panel. To return control to this panel,
move the fan knob out of REAR CNTL.
