2001 BUICK PARK AVENUE Owner's Manual

2-45 Twilight Sentinel


Twilight Sentinel turns your
headlamps on and off by
sensing how dark it
is outside.
To operate this feature, slide the control to any position
to vary the lamp timeout.
If you move the control all the way to MAX, your lamps
will remain on for three minutes after you turn off your
engine. If you move the control almost all the way in the
other direction, so it's just on, the lamps will go off
quickly when you turn off your engine. You can set this
delay time from only a few seconds to three minutes.
Light Sensor
Your Twilight Sentinel and Daytime Running Lamps
work with the light sensor on top of the instrument
panel. Don't cover it up. If you do, it will sense ªdarkº
and the headlamps will come on.
Interior Lamps
Instrument Panel Intensity Control
Instrument panel light brightness can be adjusted
by turning the headlamp knob counterclockwise
and clockwise.
Courtesy Lamps
When any door is opened, several lamps go on. They
make it easy for you to enter and leave the car. You can
also turn these lamps on by turning the headlamp knob
clockwise all the way past the normal stop.
Illuminated Entry System
When you open either front door or press the button
with the unlock symbol on the remote keyless entry
transmitter, the lamps inside your vehicle will turn on.
These lamps will turn off after about 40 seconds. These
lamps will also turn off if you start the engine or activate
the power door locks.

2-46
Delayed Entry Lighting
When you open the door, the interior lamps will come
on. When you close the door with the ignition off, the
interior lamps will stay on for 25 seconds or until the
ignition is turned to an on position. Locking the doors
with the power door lock switch will override the
delayed entry lighting feature and the lamps will turn
off right away.
Using the remote keyless entry transmitter to lock the
door will not cancel delayed lighting.
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 come on for
25 seconds after you remove the key from the ignition.
This will give you time to find the door handle or
lock switches.
Parade Dimming
This feature prohibits the dimming of your instrument
panel displays during daylight while your 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, you will be able to
dim your instrument panel displays once again.
Perimeter Lighting
When the button with the unlock symbol on the remote
keyless entry transmitter is pressed, the daytime running
lamps, parking lamps and back
-up lamps will come on
if it is dark enough outside.
This feature will only be activated when the security
feedback feature is programmed to be in Modes 1, 3 or
5 on the transmitter. Modes 0, 2 and 4 do not respond
with exterior lights flashing when unlocking the vehicle
so perimeter lighting will not be active.
This feature can be programmed on or off for
each transmitter.

inside the glove box. This will automatically turn off
when the glove box is closed.
Battery Rundown Protection
This feature shuts off all lamps that are left on for more
than 10 minutes when the ignition is off. This will keep
your battery from running down.
Mirrors
Inside Manual Day/Night Rearview Mirror
When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. Grip the mirror in the center to move it up or
down and side to side. The day/night adjustment allows
you to adjust the mirror to avoid glare from the lamps
behind you. Pull the tab forward for daytime use; push it
back for night use.

2-50
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.
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 (or the on/off button for
mirrors equipped with OnStar controls) located at the
bottom of the mirror, 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.

2-51
Mirror Operation
To turn on the automatic dimming feature, press
MIRROR (or press and hold the on/off button for about
three 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 (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.
Mirrors equipped with OnStar controls can be placed in
calibration mode by pressing and holding the on/off
button until a ªCº is shown in the compass display.

2-52
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:
1. Find your current location and variance zone number
on the following zone map.
2. Press and hold COMPASS (or the on/off button for
mirrors equipped with OnStar controls) until a zone
number appears in the display.
3. Once a zone number appears in the display, press the
COMPASS button (or the on/off button for mirrors
equipped with OnStar controls) 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.
