2-46
If you move the lever all the way to the right, the lamps
will remain on for approximately three minutes after the
ignition has been turned to OFF or ACC. If you move
the lever so it is just on, the lamps will go off quickly
when you turn the ignition out of ON. You can adjust
the delay time from only a few seconds to three minutes.
If it's dark enough outside and Twilight Sentinel is
turned off, a HEADLAMPS SUGGESTED message
will display on the Driver's Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended (it's become dark
enough outside to require the headlamps and/or other
exterior lamps). Turning on the Twilight Sentinel, the
headlamps or the fog lamps will remove the
HEADLAMPS SUGGESTED message.Light Sensor
The light sensor for the Daytime Running Lamps (DRL)
and the Twilight Sentinel is located on the driver's side
of the front defogger grille. If you cover the sensor, it
will read ªdarkº and the lamps will come on.

2-47 Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been left
on, the exterior lamps will turn off approximately ten
minutes after the ignition is turned to OFF. This protects
against draining the battery in case you have
accidentally left the headlamps or parking lamps on. The
battery saver does not work if the headlamps are turned
on after the ignition switch is turned to OFF. If you need
to leave the lamps on for more than 10 minutes, use the
exterior lamps control knob to turn the lamps back on.
To delay the lamps from turning off, see ªTwilight
Sentinelº in the Index.
Interior Lamps
Instrument Panel Intensity/Brightness
Control
With the parking lamps on, the instrument panel lighting
automatically dims when it becomes dark outside and
brightens when it becomes light outside. When it's dark,
and if the parking lamps are on, the brightness control
can be manually adjusted by using the instrument panel
brightness control.
The button is located to the
right of the Twilight
Sentinel control. Push the
button in to release it to the
outward position.
Turn the button counterclockwise to dim and clockwise
to brighten the lighting. Push the button in to return it to
the original storage position.
Interior Lamps Control
The interior lamps control,
located in the overhead
console, has three positions:
OFF, AUTO and ON.

2-48
With the control at AUTO and the front door opened,
the overhead console light, front hush panel lamps and
rear footwell lamps in the door will automatically come
on. When the rear door is opened, all the front door
lighting and rear overhead lamps will come on.
When the control is at ON, the courtesy lamps are
turned on. At OFF, the lamps are turned off. (All
automatic interior lighting functions are terminated.)
When the interior lamp control is at OFF, only the
driver's door controls and ignition switch backlighting
functions will operate.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the driver's door switches
and to the ignition key when a door is opened or if you
press the Remote Keyless Entry (RKE) transmitter
unlock button. The illuminated entry system works with
the light sensor and it must be dark outside in order for
the courtesy lamps or backlighting to turn on. The
courtesy lamps turn off approximately 25 seconds after
the last door is closed or after the ignition key is turned
to RUN or if the RKE transmitter lock button is pressed.
The courtesy lamps turn off approximately 40 seconds
after the doors are unlocked with the RKE transmitter if
no door is opened.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the parking lamps are
on. This feature works with the light sensor and is fully
automatic. When the light sensor reads darkness outside,
the instrument panel lights can be adjusted by following
the steps under ªInstrument Panel Intensity/Brightness
Control.º Backlighting to the instrument panel will also
turn on.
Reading Lamps
The reading lamps are located in the roof. These lamps
and the interior courtesy lamps come on when any door
is opened and it is dark outside. The rear lamps come on
when a rear door is opened. Press the button near the
lamps to turn them on and off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.

2-49 Battery Load Management
The battery load management feature is designed to
monitor the vehicle's 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
revolutions per minute (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, fog lamps, rear window defogger, high blower fan,
heated seats and engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer to
clear the glass, the heated seats may not get as warm as
they usually do and the fan blower may cut back to a
lower speed. For more battery saving information, see
ªBattery Saver Active Messageº in the Index.
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 the 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.
Mirrors
Electrochromic Day/Night Rearview Mirror
with Compass
Your vehicle has an electrochromic inside rearview
mirror with a compass.
By pressing the MIRROR side of the button located at
the bottom of the mirror, the position of the mirror
automatically changes to reduce glare from headlamps
behind you.

yellowblue
2-50
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.
Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells when necessary.
Mirror Operation
The right side of the button, 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 the automatic dimming, press MIRROR
again. The indicator light will be illuminated when this
feature is active.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary changing from the night back to
the day position. This delay prevents rapid changing of
the mirror as you drive under lights and through traffic.Compass Operation
Press the COMPASS side of the button 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.
Compass Calibration
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. If the letter ªCº should ever
appear in the compass window, the mirror
needs calibration.
The mirror can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or

Drive the vehicle on your everyday routine.

Ashtrays and Cigarette Lighter
(Option)
The ashtrays and cigarette lighters may be ordered
through your dealer.
NOTICE:
Don't put papers or other flammable items into
your ashtrays. Hot cigarettes or other smoking
materials could ignite them, causing a
damaging fire.
Front Ashtray
Press on the lower edge of the cover of the console
located below the climate control system to reveal the
front ashtray. To clean the ashtray, lift it out by pulling

To use the rear ashtray, lift the lid. For more
information, see your dealer.
Cigarette Lighter
The front cigarette lighter is located near the ashtray.
Press it all the way in and release. It will pop back by
itself when it's ready to light. You may also have a
lighter on the back of the center console near the rear
seat air outlet.
Note: Power to the cigarette lighter will shut off 10
minutes after the ignition is turned off. This helps to
prevent battery drainage. For more information, see
ªInadvertent Power Battery Saverº in the Index.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
