Auto Light System: System Description

The auto light control system has an optical sensor that detects outside brightness.

When the combination switch (lighting and turn signal switch) is in AUTO position, it automatically turns ON/OFF the parking, license plate, tail and headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details, refer to [SDT Function (BCM - HEADLAMP)] SDT Function (BCM - Headlamp).

Auto Light Operation

The auto light system operates the low beam and high beam headlamps, parking lamps, tail lamps and license plate lamps. The BCM monitors the combination switch (lighting and turn signal switch) position as a part of the BCM combination switch reading function. When the combination switch (lighting and turn signal switch) is in the AUTO position, the BCM automatically turns the lamps ON/OFF according to ambient light brightness. When the key is turned OFF and all doors are closed, the auto light system keeps the headlamps ON for 45 seconds.

NOTE:

Timing for when lamps turn ON/OFF can be changed by the SDT. Refer to [SDT Function (BCM - HEADLAMP)] SDT Function (BCM - Headlamp).
