Vehicle Damage Warnings
Also, in this manual you will nd 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 specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

Liftgate/Liftglass
{CAUTION:
It can be dangerous to drive with the liftgate or
liftglass open because carbon monoxide (CO)
gas can come into your vehicle. You cannot
see or smell CO. It can cause
unconsciousness and even death. If you must
drive with the liftgate open or if electrical
wiring or other cable connections must pass
through the seal between the body and the
liftgate or liftglass:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See “Climate Control
System” in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-35.
Liftgate Release
To unlock the liftgate, you may use the power door
locks or the keyless entry system described earlier.
On some vehicles the liftglass will also unlock when
the liftgate is unlocked. Press the pushbutton on
the liftglass to open it.
To open the entire liftgate, lift the handle located in
the center of the liftgate. If you open the liftgate,
the liftgate module will lock the liftglass after a
one to two second delay.
Emergency Release for Opening
Liftgate
1. Remove the trim plug, located on the inside of the
liftgate in the center, to expose the access hole in
the trim panel.
2. Use a tool to reach through the access hole in the
trim panel.
3. Pry the left release lever up to the unlock position.
Pry the right release lever up to unlatch the liftgate.
4. Reinstall the trim plug.
2-13

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 under
Engine Exhaust on page 2-35.
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 4-38.
{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 your parking brake and move the shift
lever to PARK (P).
2-36

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 or left lane,
you could hit a vehicle. Check your inside
mirror or glance over your shoulder before
changing lanes.
The passenger’s outside mirror is convex. A convex
mirror’s surface is curved so more can be seen from the
driver’s seat.
Outside Heated Mirrors
If the vehicle has this feature, when the rear window
defogger is turned on, the outside driver’s and
passenger’s rearview mirrors also heat to help clear
them of ice, snow, and condensation. SeeDual Climate
Control System on page 3-20orDual Automatic
Climate Control System on page 3-23for more
information.

Center Console Storage Area
If your vehicle has this console compartment, squeeze
the front lever while lifting the top to open it.
Your vehicle’s console will be equipped with cupholders
located on the front and rear of the storage
compartment.
The console may also contain one or more of the
following components:

Rear Climate Control
If your vehicle has the center armrest compartment, lift
the cover by pulling up on the latch handle located
underneath the front edge of the armrest. The storage
area includes slots for cassettes or compact discs.
Assist Handles
A handle above each door can be used when getting
out of your vehicle.
Luggage Carrier
{CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier — like paneling, plywood, a mattress
and so forth — the wind can catch it as you
drive along. This can cause you to lose
control. What you are carrying could be
violently torn off, and this could cause you or
other drivers to have a collision, and of course
damage your vehicle. You may be able to carry
something like this inside. But, never carry
something longer or wider than the luggage
carrier on top of your vehicle.

Ashtrays and Cigarette Lighter
Your vehicle may have this feature. The ashtray is
removable and ts into the front cupholder.
Notice:If you put papers, pins, or other ammable
items in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put ammable items in the
ashtray.
To remove the ashtray, pull the covered bin out of the
cupholder.
To use the lighter, press it in all the way, and let go.
When it’s ready, it will pop back out by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the knob is in off mode, outside air will still enter the
vehicle, and will be directed based on the position of the
mode knob. The temperature can still be adjusted
using the temperature knob.
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.
3-20

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 oor outlets. A little air is
directed toward the windshield and the side window
outlets. Cooler air is directed to the upper vents
and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with a little air directed to the windshield
and the side window outlets. The recirculation button
cannot be selected while in oor mode.
h(Recirculation):Recirculation mode is used
to recirculate the air inside of your vehicle. When
this button is pressed, an indicator light in the button
will come on to let you know that it is active. Use
this mode to help prevent outside odors and/or dust
from entering your vehicle or to help cool the air inside
of your vehicle more quickly. The air conditioning
compressor will also come on when this mode is
activated. 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 fan speed.Driver’s Side Temperature Knob:The lever on the
left side of the climate control panel is used to raise or
lower the temperature on the driver’s side of the
vehicle. Slide the lever up or down to adjust the
temperature.
Passenger’s Side Temperature Knob:The lever on
the right side of the climate control panel is used to
raise or lower the temperature on the passenger’s side
of the vehicle. Slide the lever up or down to adjust
the temperature. This lever also adjusts the temperature
to the rear seat outlets.
When the temperature outside is 0°F (-18°C) or lower,
use the engine coolant heater, if equipped, to provide
warmer air, faster to your vehicle.
#(Air Conditioning):Press this button to turn the
air-conditioning system on or off. When the button
is pressed, an indicator light will come on and the
system will begin to cool and dehumidify the air
inside of your vehicle. You may notice a slight change
in engine performance when the air conditioning
compressor shuts off and turns on again. This is normal.
