Lockout Protection
This feature protects you from locking your key in the
vehicle when the key is in the ignition and a door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all
of the doors will
lock and then the driver’s door will unlock.
Liftgate/Liftglass
It can be dangerous to drive with the liftgab- or
liftglass 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
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.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible
to steal.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light in the instrument panel cluster
will flash as you open
the door
if your ignition
is
off.
This light reminds you to activate the theft-deterrent
system. Here’s how
to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light should come
on and stay on.
3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes
off.
If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will
go off. The
headlamps and parking lamps will flash for
two minutes,
and the horn will sound for
30 seconds, then will turn
off to save the battery power. You can choose different
feedback options for the alarm. See Driver lnformation
Center
(DIC) on page 3-43.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key or use the manual
door lock.
It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key
if
the alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set
off the alarm.
If you set
off the alarm by accident, unlock any door with
the key. You can also turn
off the alarm by pressing
unlock on the remote keyless entry transmitter. The alarm
won’t stop
if you try to unlock a door any other way.

Automatic Transmission Operation
Your vehicle is equipped with an automatic transmission
and features an electronic shift position indicator
located within the instrument panel cluster.
There are several different positions for your shift lever.
PARK
(P): This position locks your drive wheels. It’s
the best position to use when you start your engine
because your -1icle
c ’t move easily.
It is aangerous to get out of your venlcle il
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t 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.
CAUTION: (Continued)
o 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). See “Shifting Into Park (P)” in the
Index.
If you’re pulling a trailer, see “Towing a
Trailer” in the Index.
REVERSE (R): Use this gear to back up.
Notices Shifting to REVERSE (R) while your vehicle
is moving forward could damage your transmission.
Shift to REVERSE
(R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
see If
You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-4 1.
NEUTRAL (N): In this position, your engine doesn’t
connect with the wheels. To restart when you’re already
moving, use NEUTRAL
(N) only.

Turn SignaVMultifunction Lever
The lever on the left side of the steering column
includes the following:
Turn and Lane Change Signals
Headlamp High/Low-Beam Changer
Flash-to-Pass
Windshield Wipers
Windshield Washer
Cruise Control
For information on the exterior lamps, see Exterior
Lamps
on page 3-13.
Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever will return automatically.
To signal a lane change, just raise
or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
As you signal a turn or a lane change, if the arrows
flash more quickly than normal, a signal bulb may be burned out and other drivers won’t see your turn
signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you signal
a turn, check for burned-out bulbs and a blown fuse
(see Fuses
and Circuit Breakers on page 5-87).
