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.

-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.

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.

2-63 Programming the HomeLink Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the ªstop and reverseº
safety feature. This includes any garage door opener
model manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
It is recommended that a new battery be installed in
your hand
-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Decide which one of the three channels (one of the
three HomeLink buttons) you want to program.
2. Press and hold the desired button on HomeLink
through Step 3.3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand
-held transmitter about 1 to 3 inches (3 to 8 cm)
from HomeLink and then press and hold the transmit
button on the hand
-held transmitter. Continue to hold
both buttons until the indicator light on HomeLink
begins to flash rapidly (this may take up to
90 seconds).
If you have trouble programming HomeLink, make sure
that you have followed the directions exactly as
described and that the battery in the hand
-held
transmitter is not weak. If you still cannot program it,
move the hand
-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
may not work with older garage door openers that do
not meet current Federal Consumer Safety Standards.
If you cannot program the transmitter after repeated
attempts, refer to ªTraining a Garage Door Opener with
Rolling Codesº later in this section or contact the
manufacturer of HomeLink at 1
-800-355-3515,
or on the internet at www.homelink.com.
Be sure to keep the original hand
-held transmitter in
case you need to erase and reprogram HomeLink.
