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:

Power Lumbar
Your vehicle may have this feature. The driver’s and
passenger’s seatback lumbar support can be adjusted
by moving a control located on the outboard side of
the seat cushions.
To increase or decrease support, hold the control
forward or rearward. Keep in mind that as your seating
position changes, as it may during long trips, so
should the position of your lumbar support. Adjust the
seat as needed.
Heated Seats
If your vehicle is equipped
with heated front seats, the
buttons are located on
the climate control panel.There is one button for the driver and one for the front
passenger. Each button has three settings, LO, HI and
off. The active setting appears on the climate control
panel display. The LO setting warms the seatback and
cushion until the seat approximates normal body
temperature. The HI setting has a slightly higher
temperature.
To turn on the heated seats, press the button once.
The seat will heat to the HI setting. Press the button
again to switch to the LO setting. Pressing the button a
third time turns the system off.
The heated seats can only be used when the ignition is
turned on. When the vehicle is turned off, the heated
seats automatically turn off. If you wish to have the
heated seats on once the vehicle is restarted, press the
button again.

Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
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 2-39.
Trunk Lock Release
The remote trunk release
button is located on the
lower portion of the
driver’s door.
To use this feature, an automatic transmission must be
in PARK (P) or NEUTRAL (N) and your manual
transmission must be in NEUTRAL with the parking
brake set.
Press the button to open the trunk. You can also press
the button with the trunk symbol on the remote
keyless entry transmitter to open the trunk.
If your vehicle is ever without power, you can still
access the trunk area. Use one of the following
procedures to open the trunk manually.
If your vehicle is equipped with the rear seat
pass-through door, do the following:
1. Fold the rear armrest down and open the
pass-through door. See “Rear-Seat Pass Through”
following for more information.
2-12

Running Your Engine While You
Are 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 2-39.
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 4-27.
{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 after you move the shift
lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) (Automatic
Transmission) on page 2-36.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-39.

Outside Heated Mirrors
When the rear window defogger is turned on, it also
warms both outside rearview mirrors to help clear them
of fog or ice. See “Rear Window Defogger” under
Dual Climate Control System on page 3-29for
more information.

Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the remote
keyless entry transmitter unlock button. If activated by
the transmitter, the lighting will remain active for
about 25 seconds. The entry lighting system uses the
light sensor; it must be dark outside in order for the
lamps to turn on. The lamps turn off about 25 seconds
after the last door is closed. They will dim to off if
the ignition key is placed in ON, or immediately
deactivate if the power locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when the
key is in the ignition and the headlamps are on. This
feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument
panel displays can be adjusted by sliding the instrument
panel brightness lever toward the symbol to brighten
or away from the symbol to dim the lighting.
Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door
is opened.For manual operation, press the button next to each
lamp to turn it on. Press it again to turn the lamp off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Accessory Power Outlets
With accessory power outlets, you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
The front accessory power outlet is located in the
ashtray on the instrument panel below the climate
control system. The outlet will have a cigarette lighter
if your vehicle has this option. Remove the cigarette
lighter to access the outlet.
The rear accessory power outlet is located on the back
of the center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover it with
the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
