Autolamp System

The autolamp system:
- Provides light sensitive automatic on-off control of the lamps normally controlled by the headlamp switch.
- Provides for increased visibility for occupants when leaving the vehicle by keeping the lamps on for a preselected period of time after the ignition switch is turned OFF.
- The preselected time lapse can be adjusted by the vehicle operator up to three minutes.

The system consists of:
- A light-sensitive light sensor amplifier
- Lighting control module
- An autolamp time delay control which is part of the lighting control module and includes an OFF position

For the autolamp system to be operational, the autolamp time delay control must be moved from the OFF position and the headlamp switch must be OFF. An autolamp indicator lamp will light when the lamps are energized by the autolamp system.

In normal operation:
- The system will turn the exterior lamps on when the light available to the light sensor amplifier decreases below a predetermined level, such as at sunset.
- The lamps will automatically turn off when the level of outside light exceeds a predetermined level, such as during daylight hours.

The system light sensor amplifier:
- Is mounted under a group of slotted holes in the instrument panel upper finish panel, left of the steering column.
- Must always be exposed to outside light to function properly.

Do not place any items in the LH corner of the windshield which may block light to the light sensor amplifier and cause erratic operation of the system.

The autolamp time delay control (part of the lighting control module), located to the right of the headlamp switch operates:
- The autolamp system is functional for automatic operation when the autolamp time delay control is moved from the OFF position.
- The longer the autolamp time delay control is held toward the max-delay, the longer the lamps will stay on after the ignition switch is turned to the OFF position.
- The current delay time is displayed in the message center when the autolamp switch is pressed.

Turning on the regular headlamp switch will override the autolamp. Automatic operation will not be possible until the regular headlamp switch is turned OFF.
