Wiper-Activated Headlamps
This feature turns on the low
-beam headlamps,
instrument panel cluster backlighting and taillamps
when the Twilight Sentinel

is in day mode and after
the windshield wipers have been in use for
approximately six seconds.
To operate the wiper
-activated headlamps, the Twilight
Sentinel must be on. If the wiper
-activated headlamps
are on and the ignition switch is turned to RUN, the
wiper
-activated headlamps will continue. When you
turn the key to OFF, the wiper
-activated headlamps
will immediately turn off. The wiper
-activated
headlamps will also turn off if you turn off the
Twilight Sentinel or the windshield wipers.
Lamps On Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver's door, you will hear a continuous
warning chime. The chime will turn off when the lamps
are turned off.
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 first sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel, so be sure it isn't covered.
The DRL system will make your high
-beam headlamps
turn on at reduced brightness in daylight when the
following conditions are met:

The ignition is on,

the exterior lamp button for the headlamps is off and

the transaxle is not in PARK (P).

2-45
When the DRL are on, only your high-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps won't be on.
When it is dark enough outside, your low
-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and your
high
-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the Twilight
Sentinel lever all the way toward OFF. The exterior
lamps will turn back on automatically when you move
the transaxle out of PARK (P).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps (If Equipped)
The cornering lamps come on when the headlamps
or parking lamps are on and you signal a turn with
the multifunction lever. They provide more light
for cornering.
Twilight Sentinel

Twilight Sentinel turns your headlamps on and off by
sensing how dark it is outside.
The lever for this feature is
located to the left of the
steering column.
To operate it, leave the exterior lamp button off.
If you slide the lever all the way to MAX, your
headlamps will remain on for about three minutes after
you turn off your engine. As you slide the lever toward
OFF, the headlamps will turn off more quickly when
you move your key from RUN. You can change this
delay time from only a few seconds to three minutes.

2-46
The exterior lamps can be completely shut off while
the vehicle is in PARK (P) by sliding the Twilight
Sentinel lever all the way toward OFF, and releasing it.
To turn the exterior lamps back on, slide the lever all
the way toward OFF again, and release it; or, shift out
of PARK (P).
Park Lamp Override Feature
If the Twilight Sentinel lighting is active, it can be
disabled by turning on the manual parking lamps.
The lighting will be disabled until the ignition is moved
from RUN or until the outside light level becomes
daylight. The outside light level changing to daylight
will cause the Twilight Sentinel feature to deactivate.
The wiper
-activated headlamps will override the
twilight disable feature.Light Sensor
Your Twilight Sentinel and
DRL work with the light
sensor located on top of the
instrument panel.
Don't cover it up. If you do, the sensor will read ªdarkº
and the Twilight Sentinel lighting will turn on.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned to LOCK and any door has been
opened. This protects draining the battery in case you
have accidentally left the headlamps or parking lamps
on. If you need to leave the lamps on for more than
10 minutes, use the manual control to turn the lamps
back on after the ignition is turned to LOCK and any
door is opened. To delay the lamps from turning off,
see ªTwilight Sentinelº in the index.

Perimeter Lighting
When the button with the unlock symbol on the remote
keyless entry transmitter is pressed, the DRL
(high
-beams at reduced intensity), parking lamps and
back
-up lamps will turn on if it is dark enough
according to the Twilight Sentinel.
You can control activation of this feature by choosing
OFF or ON when the PERIMETER LIGHTS choice is
displayed on the DIC. Make your choice by pressing the
ENG/MET button and record your choice by pressing
the RESET button. You will then be prompted to choose

Lightingº in the Index.
Exterior Lights
The EXTERIOR LIGHTS/TIMEOUT feature can be
changed to a desired setting by using the ENG/MET to
toggle from 5 to 30 seconds. Each toggle will increase
the time by five seconds. Once the desired timeout is
displayed, press RESET to record your choice and move
on to the next personal choice feature.Memory Seat Recall (If Equipped)
This feature recalls the position of your seat. When this
feature is active, the memory seat and mirror positions
will be recalled for the identified driver when the remote
keyless entry transmitter is used to enter the vehicle.
You can program this feature to be active by choosing
ON when the SEAT RECALL choice appears, or
inactive by choosing OFF when the SEAT RECALL
choice appears on the DIC. Make your choices by
pressing the ENG/MET button and store them to
memory by pressing the RESET button.
You can also program this feature to recall your memory
seat position or the exit seat position.
