Parade Dimming - Cadillac 1999 DeVille Owner's Manual

Courtesy Lamps (DeVille Only)
The courtesy lamps are located in the roof in the rear
seat. These lamps come on with the control lamp knob
or when any door is opened and it is dark outside.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the lamp control knob when a door is opened or if you
press a remote keyless entry transmitter button. Since
the illuminated entry system has a photocell, this means
that it must be dark outside in order for the courtesy
lamps or backlighting to turn on. The courtesy lamps
turn off approximately 20 seconds after the last door is
closed or after the ignition key is placed in the ignition.

Parade Dimming

This feature prohibits dimming of the digital displays
during daylight while the 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, the digital displays can be adjusted by turning the
lamp control knob counterclockwise to dim and clockwise
to brighten lighting. Backlighting to the instrument panel
will turn on regardless of light conditions.
Reading Lamps (DeVille d'Elegance and
DeVille Concours Only)
The reading lamps are located in the roof. These lamps
come on automatically when any door is opened and it is
dark outside. For manual operation, press the button to
turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
