Buick riviera 1999 User Manual

By turning the headlamp knob you can make the
instrument panel lights brighten or dim. See
“Headlamps” in the Index.

When any door is opened, several lamps go on. They
make it easy for you to enter and leave the car. To turn
on these lamps without opening the door, turn the
headlamp knob to the right.

Press the UNLOCK button on the remote keyless entry
transmitter and the interior courtesy lamps will come on
and stay on for up to one minute. The lamps will turn off
immediately when pressing the LOCK button on the
transmitter, starting the ignition or activating the power
door locks.

When you open the door to enter your vehicle, 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. Note that locking the doors will override the
delayed entry lighting feature and the lamps will turn off
right away.

This feature allows for a three to five

-

second fade out of

the courtesy lamps instead of immediate turn off.

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 pull handle or
lock switches when you exit the vehicle.

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.
