Instrument Panel Brightness
D
(Instrument Panel Brightness): This feature
controls the brightness of the instrument panel
and footwell lights, if equipped.
The button for this control is located below the exterior
lamps control.
Push the button in and release to extend the button.
Turn the button clockwise or counterclockwise to
brighten or dim the lights.
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 for the door switches and the exterior lamp
control when a door is opened or if the remote keyless
entry transmitter unlock button is pressed. If activated
due to the transmitter, the lighting remains 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
ON/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.
