Lincoln Aviator: Instrument Panel and Interior Switches Illumination / Description and Operation - Instrument Panel and Interior Switches Illumination - Overview
Overview
Dimmable Illumination
Dimmable
illumination provides backlighting to switches and control components
when the parking lamps are on. The instrument panel dimmer switch is
used to increase or decrease the level of intensity for the dimmable
backlit components. The BCM is the master module that controls the dimmable illumination.
Dimmable backlit switches and components are:
-
Headlamp switch
-
EPB switch
-
Overhead console switches
-
USB hub
-
Active park assist switch
-
Drive mode switch
-
Sunshade switch
-
Steering wheel switches
-
Emergency call switch
-
Power window switches
-
Door lock switches
When
the autolamp feature activates during the daytime, the message center
illumination remains at full intensity and cannot be dimmed using the
instrument panel dimmer switch. If the vehicle travels under a bridge or
through a tunnel and a low level of ambient light is detected, the
illumination brightness of the message center changes to the last level
set by the BCM. The message center illumination changes back to full intensity when the intense ambient light is restored.
Non-Dimmable Illumination
The non-dimmable illumination is on when the delayed accessory is active. The delayed accessory is active:
-
When the ignition is on.
-
For up to 10 minutes after the ignition is cycled from on to off and a front door is not opened.
The second row rear seat control, third row rear seat control and liftgate release switches are non-dimmable.
