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.

2-47
Interior Lamps
Instrument Panel Brightness Control
The lever for this feature is
located to the left of the
steering column.
The brightness of the instrument panel lights can be
adjusted by sliding the INTERIOR lever from LO to 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.
Courtesy Lamps
If it is dark enough outside, 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.
Illuminated Entry
If it is dark enough outside when you press the button
with the unlock symbol on the remote keyless entry
transmitter, 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.
Delayed Entry Lighting
If it is dark enough outside 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. Locking the doors will override the delayed entry
lighting feature and the lamps will turn off right away.

2-48 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
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and
stay on for approximately 25 seconds. This will give
you time to find the door pull handle or lock switches.
Once the key is inserted into the ignition the exit
lighting will be cancelled and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside 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 come on.Personal Choice Programming
This feature can be programmed in the on or off mode

turned on or off by pressing one of the buttons located
near each lamp.
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.

2-50 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 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, fan at high speed, heated seats (if
equipped) and engine cooling fans.
If your vehicle's battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Mirrors
Day/Night Manual Rearview Mirror
When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. The day
-night adjustment allows you to adjust the
mirror to avoid glare from the headlamps behind you.
Electrochromic Day/Night Rearview Mirror
(If Equipped)
Your vehicle may have an automatic electrochromic
day/night rearview mirror. Your vehicle's mirror may
also contain OnStar

controls.
This is the on/off button for mirrors equipped with
OnStar controls.
When this feature is turned on, the mirror automatically
changes to reduce glare from headlamps behind you.
A photocell on the mirror senses when it is becoming
dark outside. Another photocell built into the mirror face
senses when headlamps are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare (this change may take a
few seconds). The mirror will return to its clear daytime
state when the glare is reduced.
Mirror Operation
To turn on the automatic dimming feature, press AUTO
(or the on/off button for mirrors equipped with OnStar
controls). To turn off automatic dimming, press OFF
(or the on/off button for mirrors equipped with OnStar
controls). The indicator light will be illuminated when
this feature is active.

2-51 Electrochromic Day/Night Rearview Mirror
with Compass (If Equipped)
Your vehicle may have an electrochromic inside
rearview mirror with a compass. Your vehicle's mirror
may also contain OnStar

controls.
This is the on/off button for mirrors equipped with
OnStar controls.
Pressing the MIRROR button located at the bottom of
the mirror (or the on/off button for mirrors equipped
with OnStar controls), turns the automatic dimming
feature on or off.
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.
Mirror Operation
To turn on the automatic dimming feature, press
the MIRROR button located at the bottom of the
mirror (or press and hold the on/off button for aboutthree seconds for mirrors equipped with OnStar controls).
To turn off automatic dimming, press MIRROR (or press
and hold the on/off button for about three seconds for
mirrors equipped with OnStar controls) again. The green
indicator light will be illuminated when this feature is
active. The automatic dimming feature will be active each
time the vehicle is started.
Compass Operation
Press COMPASS (or the on/off button for mirrors
equipped with OnStar controls) 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.
Compass Calibration
If, after two seconds, the display does not show a
compass heading (N 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 C should ever appear in the compass
window, the compass may need calibration.
