Buick riviera 1999 User Manual

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 lamps at night when you are in
PARK (P), turn off the headlamps and move the twilight
sentinel control, located on the lower area of the
headlamp switch, all the way toward AUTO MIN. When
released, the spring control will return to the twilight
sentinel minimum delay position, and all exterior lamps
will turn off.

As with any vehicle, you should turn on the regular
headlamp system when you need it.

The cornering lamps are designed to come on when you
signal a turn. This will provide more light for cornering
at night.

Twilight sentinel turns your headlamps, taillamps and
parking lamps on and off by sensing how dark it is
outside. The control is located on the lower area of the
headlamp switch.

To operate this feature, leave the headlamp switch off.
The vehicle’s twilight sentinel is always enabled.

three seconds after entering a darkened

environment, the headlamps and parking lamps will turn
on. If the ignition is turned on at night, the exterior
lamps will come on.

To turn off all exterior lamps at night when you are in
PARK (P), turn off the headlamps and move the twilight
sentinel control, located on the lower area of the
headlamp switch, all the way toward AUTO MIN. When
released, the spring control will return to the twilight
sentinel minimum delay position, and all exterior lamps
will turn off.

If you move the control all the way to AUTO MAX,
your lamps will remain on for three minutes after you
turn off your engine. If you move the control toward
AUTO MIN, the lamps will go off quickly when you
turn off your engine. You can set this delay time for only
a few seconds or up to three minutes.

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 read “dark” and the
headlamps will come on.
