Buick 2004 Park Avenue - Manual (Page 132)

When it is dark enough outside, your high-beam
headlamps will change to low-beam headlamps at full
brightness. The other lamps that turn on with your
headlamps will also turn on. When it is bright enough
outside, the regular lamps will turn off, and your
high-beam headlamps change to the reduced brightness
of DRL.
To idle your vehicle with the DRL off, shift the transaxle
into PARK (P). The DRL will stay off until you shift
out of PARK (P).
To turn off all exterior lighting at night when you are
parked, turn off the exterior lamp control and slide the
Twilight Sentinel
® control all the way to the left.
When released, the control will return to the Twilight
Sentinel
® minimum delay position and the lights will
turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps
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.
To operate this feature, slide the control to any position
to vary the lamp time-out.
You can set the delay time from only a few seconds to
three minutes. 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 is just on, the lamps will go off
quickly when you turn off your engine. Sliding the control
to OFF, turns off the Twilight Sentinel
® feature.
Light Sensor
Your Twilight Sentinel ® and DRL work with the light
sensor on top of the instrument panel. Do not cover it
up. If you do, it will sense “dark” and the headlamps will
come on.
