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 ash as you open
the door if your ignition
is off.
This light reminds you to activate the theft-deterrent
system.To activate the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE)
transmitter. The security light will illuminate to
inform the driver the system is arming. If a door is
open when the doors are locked, the security
light will ash.
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 the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the delay
timer has expired. SeeDelayed Locking on
page 2-11.
If a locked door is opened without the RKE transmitter,
the alarm will go off. The headlamps and parking
lamps will ash and the horn will sound for 30 seconds,
then will turn off to save the battery power.
2-24

Remember, the theft-deterrent system will not activate if
you lock the doors with the vehicle’s 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
RKE transmitter. You should also remember that you
can start your vehicle with the correct ignition key if the
alarm has been set off.
Here is how to avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door keyafterthe doors are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off the
alarm.
If you set off the alarm by accident, press unlock on the
RKE transmitter or place the key in the ignition and
turn it to START to turn it off. The alarm will not stop
if you try to unlock a door any other way.
Testing the Alarm
To test the alarm:
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
power door lock switch while the door is open, or
with the RKE 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 is
not operational.
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,
seeInstrument Panel Fuse Block on page 5-111and
Underhood Fuse Block on page 5-113.
If the alarm does not sound or the headlamps do not
ash, the vehicle should be serviced by your
dealer/retailer.
2-25

Outside Automatic Dimming Mirror
If the vehicle has this feature, the driver’s outside mirror
adjusts for the glare of the headlamps behind you.
SeeAutomatic Dimming Rearview Mirror with Compass
and Temperature Display on page 2-45.
Park Tilt Mirrors
The vehicle’s outside mirrors can also perform a park tilt
function. This causes the passenger’s and/or driver’s
mirror to tilt to a preselected position when the vehicle is
in REVERSE (R). This feature may be useful in
viewing the curb when parallel parking.
When the vehicle is shifted out of REVERSE (R) and a
short delay has occurred, the passenger’s and/or
driver’s mirror will return to its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory as
the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. SeeDIC Vehicle Customization
(With DIC Buttons) on page 3-63for more information.
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 lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger side mirror is convex. A convex mirror’s
surface is curved so more can be seen from the
driver seat. It also makes things, like other vehicles,
look farther away than they really are.
Outside Heated Mirrors
The vehicle may have outside heated mirrors which
help clear them of condensation, snow, and ice.
When the rear window defogger button is pressed, the
heated mirrors are also turned on. See “Rear Window
Defogger” underDual Automatic Climate Control System
on page 3-22for more information.

3-7

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 nished, the lever will
return automatically.
To signal a lane change, raise or lower the lever for
less than one second until the arrow starts to ash.
This will cause the turn signals to automatically
ash three times. It will ash six times if the tow-haul
mode is active. Holding the turn signal lever for
more than one second will cause the turn signals to
ash until you release the lever. The lever will return
by itself when it is released.
An arrow on the instrument
panel cluster will ash
in the direction of the turn
or lane change.
As you signal a turn or a lane change, if the arrows
ash more quickly than normal, a signal bulb may
be burned out and other drivers will not see your
turn signal.If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and a blown
fuse. SeeInstrument Panel Fuse Block on page 5-111
andUnderhood Fuse Block on page 5-113.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ash of the turn
signal and the message TURN SIGNAL ON will also
appear in the DIC. SeeDIC Warnings and Messages on
page 3-56. To turn the chime and message off, move the
turn signal lever to the off position.
Headlamp High/Low-Beam Changer
53(Headlamp High/Low Beam Changer):
To change the headlamps from low to high beam,
push the lever toward the instrument panel. To return
to low-beam headlamps, pull the multifunction lever
toward you. Then release it.
When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.
3-8

Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are in the automatic
position.
To use it, pull the turn signal lever toward you, then
release it.
If your headlamps are in the automatic position or on
low beam, your high-beam headlamps will turn on.
They will stay on as long as you hold the lever
toward you. The high-beam indicator on the instrument
panel cluster will come on. Release the lever to
return to normal operation.
Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the band to
mist. Hold it there until the wipers start. Then let go.
The wipers will stop after one wipe. If you want
more wipes, hold the band on mist longer.
6(Delay):You can set the wiper speed for a long or
short delay between wipes. This can be very useful
in light rain or snow. Turn the band to choose the delay
time. The closer to the top of the lever, the shorter
the delay.
6(Low Speed):For steady wiping at low speed,
turn the band away from you to the rst solid band past
the delay settings.
1(High Speed):For high-speed wiping, turn the
band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If your blades do
become worn or damaged, get new blades or blade
inserts.
3-9

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon the vehicle’s speed, load, and the steepness
of the hills. When going up steep hills, you might
have to step on the accelerator pedal to maintain the
vehicle’s speed. When going downhill, you might have
to brake or shift to a lower gear to keep the vehicle’s
speed down. When the brakes are applied the cruise
control turns off. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[button on the steering wheel.
Press theTbutton on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.
Exterior Lamps
The exterior lamps
control is located on
the instrument panel
to the left of the
steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
3-15

The exterior lamps control has four positions:
O(Off):Turn the control to this position to turn off the
automatic headlamps and daytime running lamps (DRL).
Turning the headlamp control to the off position again will
turn the automatic headlamps or DRL back on.
For vehicles rst sold in Canada, the off position will
only work for vehicles that are shifted into the PARK (P)
position.
AUTO (Automatic):Turn the control to this position
to automatically turn on the headlamps at normal
brightness, together with the following:
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
;(Parking Lamps):Turn the control to this position to
turn on the parking lamps together with the following:
Instrument Panel Lights
Taillamps
License Plate Lamps
2(Headlamps):Turn the control to this position to
turn on the headlamps together with the following lamps
listed below.
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
When the headlamps are turned on while the ignition is
on, the headlamps turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the ignition is off, the headlamps will
stay on for 10 minutes before automatically turning off
to prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp
on position to make the headlamps stay on for an
additional 10 minutes.
3-16

Headlamps on Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned
on and your key is out of the ignition. To turn off
the chime, turn the headlamp switch to off or AUTO
and then back on, or close and re-open the door.
In the AUTO mode, the headlamps turn off once the
ignition is in LOCK or may remain on until the headlamp
delay ends (if enabled in the DIC). See “Exit Lighting”
underDIC Vehicle Customization (With DIC Buttons)
on page 3-63.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release.
For vehicles rst sold in Canada, the transmission
must be in the PARK (P) position, before the
DRL lamps can be turned off.
