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/UNLOCK, 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.
Parking Lamps
Press the PARK button to turn on the parking lamps.
Press it again to turn them off. (If the parking lamps
were turned on with the PARK button, they must be
turned off with that button).
When the parking lamps are turned on during the day,
the instrument panel cluster lights and backlighting to
buttons will turn on. At night, the brightness of this
lighting can be adjusted by the instrument panel
intensity/brightness control if the ignition key is turned
to RUN. The radio and climate control displays will also
be on. When it becomes dark outside, the instrument
panel intensity/brightness control will operate all
instrument panel lighting.
Lamps On Reminder
If you leave the manual headlamp or parking lamp
switch 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
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.
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 ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).
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 control 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 are designed to turn on when
you signal a turn. This will provide more lighting
when cornering.
Twilight Sentinel

Twilight Sentinel turns your
lamps on and off by sensing
how dark it is outside.
To operate it, leave the lamp switch off.
If you move the control all the way to MAX, your
headlamps will remain on for about three minutes after
you turn off your engine. As you move the control 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.
The exterior lamps can be completely shut off while the
vehicle is in PARK (P) by sliding the Twilight Sentinel
control all the way toward OFF, and release. To turn the
exterior lamps back on, slide the control all the way
toward OFF again, and release; 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. If it becomes
dark again, the parking lamps will have to be turned on
again. (If the parking lamps are already on, they will
have to be turned off, then back on to disable twilight).
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.
Interior Lamps
Instrument Panel Intensity/
Brightness Control
The brightness of the
instrument panel lights can
be adjusted by moving the
INTERIOR lever between
LO and HI.
The instrument panel lights will be on only when the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the way
to the top, to HI.

2-47 Courtesy Lamps
When any door is opened, several lamps go on. They
make it easy for you to enter and leave the vehicle. You
can also turn these lamps on by sliding the INTERIOR
lever all the way to the top.
Delayed Entry Lighting
When you open the door, the interior lamps will turn on.
When you close the door with the ignition off, the
interior lamps will stay on for up to 25 seconds or until
the ignition is turned to an on position. When the lamps
turn off as a result of the 25 second timer or the ignition
switch being turned on, the lighting will deactivate via
the theater dimming effect. Note that locking the doors
will override the delayed entry lighting feature and the
lamps will turn off right away.
Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
With this feature, the interior lamps will turn on and stay
on for approximately 25 seconds after you remove the
key from the ignition. This will give you time to find the
door pull handle or lock switches. The exit lighting will
be cancelled and the lighting will be theater dim once
the key is reinserted into the ignition.
Illuminated Entry
Press the button with the unlock symbol on the remote
keyless entry transmitter and the interior courtesy lamps
will turn on and stay on for approximately 40 seconds.
The lamps will turn off immediately by pressing the
button with the lock symbol on the remote keyless entry
transmitter, turning the ignition key to RUN or
activating the power door locks.
Perimeter Lighting
When the button with the unlock symbol on the remote
keyless entry transmitter is pressed, the DRL headlamps,
parking lamps and back
-up lamps will turn on if it is
dark enough outside.

2-49 Battery Load Management
The battery load management feature is designed to
monitor the vehicle electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher RPM setting than normal to make sure the battery
charges. High electrical loads may occur when several
of the following are on: headlamps, high beams, rear
window defogger, high blower fan, heated seats
(if equipped) and engine cooling fans.
Exterior Lighting Battery Saver
If the manual lamp control has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned OFF/LOCK. 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. To delay the lamps from turning off,
see ªTwilight Sentinel

º in the index.
Front Reading Lamps
Front seat reading lamps are turned on or off by pressing
one of the lamps buttons.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's battery
against drainage from the interior lamps, trunk lamp, glove
box lamp, cigarette lighters or garage door opener. When
the ignition is turned off, the power to these features will
automatically turn off after 10 minutes. Power will be
restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch is
turned on. To restore power back to the cigarette lighters
the ignition must be turned back to RUN.

Mirror Operation
To turn on the automatic dimming feature, press AUTO.
To turn off automatic dimming, press OFF. The green
indicator light will be illuminated when this feature
is active.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing of
the mirror as you drive under lights and through traffic.
Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells when necessary.
Electrochromic Day/Night Rearview Mirror
with Compass (If Equipped)
Your vehicle may have an electrochromic inside
rearview mirror with a compass.
When set in the MIRROR position, this mirror
automatically changes to reduce glare from headlamps
behind you. A time delay feature prevents rapid
changing from the day to night positions while driving
under lights and through traffic.
The mirror also includes an eight
-point compass display in
the upper right corner of the mirror face. When on, the
compass automatically calibrates as the vehicle is driven.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray glass
cleaner directly on the mirror as that may cause the liquid
cleaner to enter the mirror housing. Use a cotton swab and
glass cleaner to clean the photocells when necessary.

Mirror Operation
The right side of the switch located at the bottom of the
mirror turns the electrochromic mirror on and off. To
turn on the automatic dimming feature, press MIRROR.
To turn off automatic dimming, press MIRROR again.
The green indicator light will be illuminated when this
feature is active.
Compass Operation
Press the COMPASS button once to turn the compass
on or off.When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the compass heading.
If, after two seconds, the display does not show a compass
heading (ªNº for North, for example), there may be a
strong magnetic field interfering with the compass. Such
interference may be caused by a magnetic antenna mount,
magnetic note pad holder or a similar magnetic item. You
should remove the interference.
Compass Calibration
In order to calibrate, the letter ªCº must be displayed in
the mirror compass window. If ªCº is not displayed,
push the ªCOMPASSº button for approximately
eight seconds. The zone number will come up first and
then the letter ªCº will be displayed.
The compass can be calibrated in one of two ways:

Drive the vehicle in two complete 360 circles at
five mph (8 km/h) or less until the display reads a
direction, or

Drive the vehicle on your everyday routine.
