Courtesy Lamps; Entry Lighting; Parade Dimming; Reading Lamps - Cadillac 2007 DTS Owner's Manual

Courtesy Lamps

The courtesy lamps are located on the headliner
above the rear seat. These lamps come on by
turning the instrument panel brightness knob fully
clockwise or when any door is opened and it is
dark outside. Puddle lamps are located on
the bottom of the front and rear door trim.
Professional vehicles have an additional dome
lamp and also opera lamps.

Entry Lighting

This feature turns on the courtesy lamps and the
backlighting to the door switches and to the exterior
lamp control when a door is opened or if you press
the remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the entry
lighting system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn
on. The courtesy lamps turn off approximately
25 seconds after the last door is closed. They will
dim to off if the ignition key is turned to RUN, or
immediately deactivate if the power locks are
activated.

Parade Dimming

This feature prohibits dimming of the digital
displays and backlighting during daylight hours
when the key is in the ignition and the headlamps
are on. This feature is fully automatic. When
the light sensor reads darkness outside and the
parking lamps are active, the digital displays
can be adjusted by turning the instrument panel
brightness knob counterclockwise to dim and
clockwise to brighten lighting.

Reading Lamps

The reading lamps are located on the overhead
console on the headliner and in the rear door
opening. 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.
