2-44 Twilight Sentinel
This control is located
next to the exterior lamp
control knob. It
automatically turns the
lamps on and off by sensing
how dark it is outside.
To operate the Twilight Sentinel, leave the exterior lamp
control knob off and move the TWILIGHT control to
any position but OFF.If you move the control all the way to the right, the
lamps will remain on for approximately three minutes
after the ignition has been turned to OFF or LOCK.
If you move the control so it is just on, the lamps will
go off quickly when you turn the ignition out of RUN.
You can adjust the delay time from only a few seconds
to three minutes.
If it's dark enough outside and the Twilight Sentinel
control is off, a HEADLAMPS SUGGESTED message
will display on the Driver 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 in the center of the
front defogger grille. If you cover the sensor, it will read
ªdarkº and the lamps will come on.
Exterior Lighting Battery Saver
If the manual parking lamp control has been left on, the
exterior lamps will turn off approximately 10 minutes
after the ignition is turned to LOCK or ACCESSORY.
This protects against draining the battery in case you
have accidentally left the headlamps or parking lamps
on. If you need to purposely leave the lamps on for more
than 10 minutes with the ignition in LOCK or
ACCESSORY, turn the exterior lamps control knob off
and then back on. To delay the lamps from turning off,
see ªTwilight Sentinelº in the Index.

Interior Lamps
Instrument Panel
Intensity/Brightness Control
The digital displays automatically dim when it becomes
dark outside and your lights are on. When it's dark, the
brightness control can be manually adjusted by turning
the exterior lamps control knob counterclockwise to dim
and clockwise to brighten the lighting. The digital
displays automatically brighten when it becomes light
outside, although backlighting will remain active at the
selected brightness as long as the lights are on.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door controls and to
the exterior lamps control knob when a door is opened
or if you press a remote keyless entry transmitter button.
Since the illuminated entry system has a photocell, this
means that it must be dark outside in order for the
courtesy lamps or backlighting to turn on. The courtesy
lamps turn off approximately 20 seconds after the last
door is closed or after the ignition is turned to RUN.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the headlamps are on.
This feature operates with the light sensor for the
Twilight Sentinel and is fully automatic. When the light
sensor reads darkness outside, the instrument panel
lights can be adjusted by turning the exterior lamps
control knob counterclockwise to dim and clockwise to
brighten lighting. Backlighting to the instrument panel
will turn on, regardless of light conditions.
Reading Lamps
The reading lamps are located either in the headliner or
above the windows if you have a sunroof. To turn them
on, turn the exterior lamps control knob all the way
clockwise. These lamps and the interior courtesy lamps
automatically come on when either door is opened and it
is dark outside. For manual operation, press the button
to turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.

2-47 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 (three minutes if a new car has 15 miles
(24 km) or less). Power will be restored for an additional
10 minutes if either door is opened, the trunk is opened
or the courtesy lamps are turned on.
Storage Mode Personalization
This feature is for long-term use and must be
programmed through the Driver Information Center
(DIC) while the ignition is in RUN. Storage mode
personalization protects the battery by placing your
vehicle in a storage mode so that the radio, amplifiers,
instrument panel cluster and remote keyless entry will
not drain the battery over a long period of time. For
programming information, see ªMemory and
Personalization Featuresº in the Index.
Mirrors
Electrochromic Day/Night Rearview Mirror
with Compass
Your vehicle has an electrochromic inside rearview
mirror with a compass. Your vehicle's mirror also
contains OnStar
controls. For more information about
OnStar, see ªOnStarº in the Index.
This is the on/off button, located on the lower left
side of the mirror for the electrochromic and compass
functions of the rearview mirror.
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.

2-48
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 and
hold the on/off button for about three seconds. To turn
off automatic dimming, press and hold the on/off button
for about three seconds 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 the on/off 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.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 compass may
need calibration.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display
reads a direction.
The compass can be placed in calibration mode by
pressing and holding the on/off button until a ªCº is
shown in the compass display.

Compass Variance
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, as during a long distance
cross
-country trip, it will be necessary to adjust for
compass variance. Compass variance is the difference
between earth's magnetic north and true geographic
north. If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone number
on the following zone map.
2. Press and hold the on/off button until a zone number
appears in the display.
3. Once the zone number appears in the display, press
the on/off button quickly until the correct zone
number appears in the display. Stop pressing the
button and the mirror will return to normal
operation. If ªCº appears in the compass window, the
compass may need calibration. See ªCompass
Calibrationº explained previously.

2-50 Power Remote Control Mirror (Heated)
Your vehicle has an electric
mirror control located on
the driver's door armrest.
Move the R/L switch in the middle of the control to
choose the right (passenger's side) or left (driver's side)
mirror. To adjust the mirror, push the arrow control in
the direction you want the mirror to go. Adjust each
mirror so you can see the side of your vehicle and the
area behind your vehicle.
The mirrors can also be programmed for personalization
if you have the optional memory package. For more
information, see ªMemory Seat and Mirrorsº in
the Index.
To activate the heated mirrors, press the rear window
defogger button. See ªRear Window Defoggerº in the Index.
Driver's Outside Auto-Dimming
Rearview Mirror
Only the driver's side outside mirror will adjust for the
glare of headlamps behind you. This feature is
controlled by the on and off settings on the
electrochromic mirror. See ªElectrochromic Day/Night
Rearview Mirror with Compassº in the Index.
Curb View Assist Mirror (If Equipped)
If your vehicle is equipped with memory mirrors, it will
also be equipped with the curb view assist mirror
feature. This feature will cause the passenger's mirror to
tilt when the vehicle is moving in REVERSE (R). This
feature may be useful in allowing you to view the curb
when you are parallel parking (selected/programmed
through personalization on the DIC).
When the vehicle is shifted out of REVERSE (R) and a
five second delay has occurred, the passenger's mirror
will return to its original position. If further adjustment
is needed after the mirror is tilted, the mirror switch may
be used. The mirror then returns to its original position.

2-51 Convex Outside Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from
the driver's seat. This mirror does not have a
dimming feature.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.
