2-5 Power Door Locks
Push the side of the door lock switch with the light in it
to lock all the doors and push the other side of the door
lock switch to unlock all doors.
Automatic Door Locks
Close the doors and turn on the ignition. Every time you
move the shift lever out of PARK (P), all of the doors
will lock. The doors will unlock every time you stop the
vehicle and move the shift lever into PARK (P). If
someone needs to get out while your vehicle is not in
PARK (P), have that person use the manual or power
lock. When the door is closed again, it will not lock
automatically. Use the manual or power lock to lock the
door again.
Programmable Automatic Door Locks
Each remote keyless entry transmitter supplied with
your vehicle can be programmed to suit each driver's
door lock preference. The two remote keyless entry
transmitters are identified on the back with either aª1º
or a ª2º, which allows either driver to program their
own door locks.
The automatic door locks can be programmed (using the
remote keyless entry transmitter) for various lock and
unlock options.
With the ignition on, the transmission in PARK (P) and
the brake pedal pressed down, you are now ready to
begin programming.

If your vehicle loses power
temporarily, you can
manually open the trunk
using the trunk release
handle. The handle is
located on the underside of
the trunk lid on the driver's
side and can be accessed
through the fold
-down
rear seats.
Fold down the driver's side rear seat and reach through
to the trunk compartment to find the release handle.
Pulling the handle opens the trunk. For more
information on how to fold the rear seats, see ªFolding
the Rear Seatº in the Index.
Theft
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. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transmission. And remember to lock
the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.

Wiper-Activated Headlamps
This feature activates the low
-beam headlamps, parking
lamps, sidemarker lamps and taillamps after the
windshield wipers have been in use for about
20 seconds.
The wiper
-activated headlamps light the way in poor
weather and also make your vehicle more visible to
other drivers. If the wipers are on and the ignition switch
is turned off, the headlamps will immediately turn off.
The headlamps will also deactivate if the windshield
wipers have been turned off for about 20 seconds.
Perimeter Lighting
This feature turns on the low-beam headlamps, parking
lamps, sidemarker lamps and taillamps for about
20 seconds after the unlock button on the remote
keyless entry transmitter is pressed. Perimeter lighting
immediately ends when your vehicle's ignition is turned
to ON or START.
Lamps On Reminder
You will hear a warning chime if you open the door
while leaving the lamps on, if the manual headlamp
control is activated. An exception to this is when you're
using the Twilight Sentinel.
Daytime Running Lamps
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.
The DRL system will make the high
-beam headlamps
come on at reduced brightness when:
your vehicle's ignition is in ON or START,
the low
-beam headlamps are off (the manual lamp
switch is in the off or park lamp position) and
your vehicle's transmission is shifted out of
PARK (P).
When DRL are on, only the high
-beam headlamps (at
reduced brightness) will be on. No other exterior lamps
such as the parking lamps, taillamps, etc. will be on
when the DRL are being used. The instrument panel
won't be lit up either.

When the Twilight Sentinel is on and it's dark enough
outside, the high
-beam headlamps (at reduced intensity)
will change to low
-beam headlamps. When it's bright
enough outside, the regular lamps will go off, and the
high
-beam headlamps change to the reduced brightness
of DRL.
To idle your vehicle with the headlamps off, turn off the
Twilight Sentinel switch and shift the transmission into
PARK (P). Placing your vehicle in PARK (P) disables
the DRL. The DRL will stay off until you shift out of
PARK (P).
If you're not in PARK (P)
and the Twilight Sentinel
system is turned off (and it's
dark enough outside), the
DRL will remain active and
this light on the instrument
panel will appear.
This is a reminder that headlamps are required.The following conditions will override the DRL:
your vehicle's transmission is shifted back into
PARK (P) with the ignition in ON or START,
the low
-beam headlamps are turned on (using the
manual lamp control dial),
the wiper
-activated headlamps are in use (DRL will
come back on 20 seconds after wipers have
turned off),
using the flash
-to-pass feature and
turning on the Twilight Sentinel.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

If you rotate the control dial all the way up, the lamps
will remain on for about three minutes after the ignition
has been turned to OFF or LOCK. If you rotate the
control dial all the way down, the lamps will go off
quickly. You can adjust the delay time from a few
seconds up to three minutes.
To turn the Twilight Sentinel off, press the OFF button
again. The indicator light in the button will be on. This
lets the driver know that the system has been turned off.
The Twilight Sentinel also turns off if the ignition is
turned to OFF or to LOCK.
This light in the instrument
panel will come on if the
ignition is on and:
the headlamps have not been manually turned on,
the Twilight Sentinel senses it is dark outside,
the Twilight Sentinel is OFF and
the transmission is not in PARK (P).Light Sensor
The light sensor for the
Twilight Sentinel is located
in the center of the front
defogger grille, near
the windshield.
If you cover the sensor, it will read ªdarkº and the
parking lamps and low
-beam headlamps will come on.
