Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
Theft-Deterrent System
If your vehicle has this
feature, the security light is
located on the instrument
panel cluster.
To activate the theft-deterrent system:
1. Open the door.
2. Lock the door with the 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 or trunk is opened without using the
key in the driver’s door key cylinder or the transmitter, a
ten second pre-alarm will occur. The horn will chirp and
the lights will ash. If the key is not placed in the ignition
and turned to START or the door is not unlocked by
pressing the unlock button on the transmitter during the
ten second pre-alarm, the alarm will go off. Your vehicle’s
headlamps will ash and the horn will sound for about
30 seconds, then will turn off to save the battery power.
The theft-deterrent system will not activate if the doors
are locked with the vehicle’s key or the manual door
lock. It activates only if the power door lock switch
is used while the door is open or with the transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm has
been set off.
To avoid setting off the alarm by accident:
Lock the vehicle with the door key after the doors
are closed.
Always unlock a door with the transmitter. Unlocking
a door any other way will set off the alarm.
If you set off the alarm by accident, turn off the alarm by
pressing the unlock button on the transmitter. The alarm
will not stop if you try to unlock a door any other way.
2-28

Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door.
This should set off the alarm.
While the alarm is set, the power door unlock switch will
not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 5-123
Fuses and Circuit Breakers.
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by your
dealer/retailer.

feature, the power tilt
wheel control is located
on the left side of the
steering column.

Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster ashes in the
direction of the turn or
lane change.
Raise or lower the lever until the arrow starts to ash
to signal a lane change. Hold it briey until the lane
change is complete. The arrow will automatically ash
three times The lever returns to its original position when
it is released.
Rapid ashing of arrows when signaling for a turn or
lane change can be caused by a burned-out signal bulb.
Other drivers will not see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse for burned-out bulbs if the
arrow fails to work when signaling a turn. SeeFuses and
Circuit Breakers on page 5-123for more information.
Turn Signal On Chime
If the turn signal is left on for about 1 mile (1.6 km),
a warning chime will sound and the TURN SIGNAL ON
message will appear on the Driver Information Center
(DIC) display. See “Turn Signal On” underDIC Warnings
and Messages on page 3-56for more information.
Headlamp High/Low-Beam Changer
Push forward on the turn signal/multifunction lever to
change the headlamps from low to high beam. Pull the
lever back and then release it to change from high
to low beam.
If the vehicle is turned off while the high beams are on,
they will come on the next time the vehicle is started.
The highbeam light on the
instrument panel cluster,
comes on while the
high-beam headlamps
are on.
3-8

Flash-to-Pass
This feature allows you to use the high-beam headlamps
to signal the driver in front of you that you want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use this feature. When this is done the following
will occur:
If the headlamps are off, in low-beam or in Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They will stay on as long as
the lever is held there. Release the lever to turn
them off.
For vehicles with High Intensity Discharge (HID)
headlamps, the low-beam headlamps must be
on to activate the high-beam headlamps. SeeHigh
Intensity Discharge (HID) Lighting on page 5-55.
If the headlamps are already in high-beam mode,
they will remain on high-beam.
Windshield Wipers
The lever on the right side of the steering column
operates the windshield wipers.
7(Mist):Pull the lever down and release it for a
single wiping cycle. The lever will return to its original
position. For more cycles, hold the lever down
before releasing it.
&(Delay):Move the lever to this position to set a
delay between wipes. Turn the delay adjustment band
to set the length of the delay.
6(Delay Adjustment):Use this band to set the length
of the delay between wipes when using the delay
feature. The closer the band is moved towards
7,
the longer the delay. The windshield wiper lever must be
in delay for this feature to work.
3-9

1 (Low Speed):Move the lever to this position for
slow, steady wiping cycles.
2 (High Speed):Move the lever to this position for
rapid wiping cycles.
If the windshield wipers are in use for about six seconds
while you are driving, the exterior lamps come on
automatically if the exterior lamp control is in AUTO.
SeeWiper Activated Headlamps on page 3-17for
more information.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
gently loosen or thaw them. If the blades do become
damaged, install new blades. For more information, see
Windshield Wiper Blade Replacement on page 5-57.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.Rainsense™ Wipers
Vehicles with Rainsense™ windshield wipers, have a
moisture sensor for this feature mounted on the interior
side of the windshield behind the rearview mirror.
This sensor automatically operates the wipers by
monitoring the amount of moisture build-up on the
windshield. Wipes occur as needed to clear the
windshield depending on driving conditions and the
sensitivity setting. In light rain or snow, fewer wipes
will occur. In heavy rain or snow, wipes occur more
frequently. If the system is left on for long periods of
time, occasional wipes may occur without any moisture
on the windshield. This is normal and indicates that
the Rainsense™ system is activated.
The wiper control should be left in the off position,
unless the wiper is needed.
The Rainsense™ system is sensitive to vibration and
can activate if something hits the windshield or if
the vehicle hits a bump.
