L(Remote Alarm):Press this button to activate an
alarm. The ignition must be in OFF or ACC for the
remote alarm to work. When you press the remote
button, the headlamps will ash, the horn will sound
repeatedly and your interior lamps will turn on attracting
attention if you need it. The alarm will continue until
one of the following occurs:
The remote alarm button is pressed a second time,
the vehicle’s ignition is turned to ON or
an alarm period of 110 seconds has elapsed.
V(Trunk Release):Press the button to release
the trunk.
Operating the remote keyless entry transmitter may
interact with the content theft-deterrent system, if your
vehicle has this option. SeeContent Theft-Deterrent
on page 2-15.
Transmitter Verication
This feature provides feedback that a command has
been received by the vehicle, if your key fob has been
programmed to Mode 3: Full, see Fob Horn (Remote
Audible Verication) underVehicle Personalization
on page 2-44for more information. The headlamps and
back-up lamps will ash on every lock command and
on the rst unlock command. The horn will also
sound once for every lock and twice for the rst unlock
command. Silent operation and other options may
be selected for this feature.
If your vehicle has the optional content theft-deterrent
system, the rst time the remote unlock is received and
the alarm has been previously activated, three ashes
from the headlamps will be seen and three chirps will be
heard to indicate an alarm condition has occurred
since last arming. SeeContent Theft-Deterrent on
page 2-15.

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 may have the optional content
theft-deterrent alarm system.
With this system, a light on the radio will ash.
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 light on
the radio should come on and stay on. If you
are using the remote keyless entry transmitter, the
door does not need to be open.
3. Close all doors. The light on the radio will slowly
ash once the system is armed.Once armed, the alarm will go off if someone tries to
enter the vehicle (without using the remote keyless entry
transmitter or a key) or turns the ignition on with an
incorrect key. The horn will sound and the headlamps
and back-up lamps will ash for approximately two
minutes.
When the alarm is armed, the trunk may be opened with
the remote keyless entry transmitter. If you use the key to
open the trunk, the alarm will sound. The power door lock
switches are also disabled. You must use your remote
keyless entry transmitter or your key to unlock the doors
when the system is armed.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
lock switch to lock the doors while any door or the
trunk is open and the key is removed from the ignition.
The light on the radio ashes quickly to let you know
when the system is ready to arm with the power
door lock switches. The light on the radio will stop
ashing and stay on when you press the bottom of the
power lock switch, to let you know the system is
arming. After all doors and the trunk are closed and
locked, the light on the radio will ash slowly to let you
know the system is armed.

automatic dimming feature off, press the center
button again.
To keep the photocells operating well, occasionally

Turn and Lane-Change Indicator
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 nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If the arrow ashes faster than normal as you signal a
turn or a lane change, 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 then check the
fuse. SeeFuses and Circuit Breakers on page 5-103.
Turn Signal On Chime
If you leave either one of your turn signals on and drive
more than 3/4 mile (1.2 km), a chime will sound to
alert you.

high beams, or high to low, pull the multifunction lever
all the way toward you. Then release it.
While the high beams are
on, this light on the
instrument panel cluster
also will be on.
This light works only while the ignition key is in the
ON position, and your fog lamps (if equipped) will not
be illuminated when your high beams are on.

Flash-to-Pass
With the turn signal lever in the low-beam position,
pull the lever toward you momentarily to switch
to high-beams (to signal that you are going to pass).
If you have the headlamps on, they will return to
low-beams when you release the lever.
This feature operates even when the headlamps are off.

band labeled WIPER, located on the multifunction lever,
upward or downward.

cycles turn the band upward.LO (Low Speed):Turn the band up to LO for a steady
wiping at a low speed.
HI (High Speed):Turn the band up to HI for a steady
wiping at a high speed.
MIST:Turn the band downward to MIST for a single
wiping cycle. Hold the band at this setting until the
windshield wipers start, then release it. The windshield
wipers will stop after one wipe. If additional cycles
are needed, hold the band on MIST longer.
Be sure to clear ice and snow from the wiper blades
before using them. Hold the band at this setting until the
windshield wipers start, then release it. The windshield
wipers will stop after one wipe. If additional cycles
are needed, hold the band on MIST longer.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload. If your blades
become damaged, get new blades or blade inserts. See
