Vehicle Damage Warnings
Also, in this book you willfind 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 helpfiguring out a specificnameofa
component, gage or indicator, reference the following

Running Your Engine While You
Are Parked
It’s 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 under
“Engine Exhaust.”
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the 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. See
“Winter Driving”in the Index.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brakefirmly set. Your vehicle can
roll. Don’t leave your vehicle when the engine
is running unless you have to. If you’ve left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle won’t move, even when
you’re on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle won’t
move. SeeShifting Into Park (P) on page 2-27.
If you’re pulling a trailer, seeTowing a Trailer on
page 4-31.

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:
)(Bi-Level):This mode directs approximately half
of the air to the instrument panel outlets and directs
most of the remaining air to thefloor 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
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.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.

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 thefloor 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 thefloor 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 airflowing
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.

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
