LIGHTING SYSTEM
T-46prose procedureU.S. spec.
Description
The headlight system consists of two halogen headlights mounted on retractable mechanisms, a headlight switch in the combination switch, and a retractor switch between the center ventilation outlets. When the headlight switch is rotated to the second position, the headlights are activated and the headlight retractor motors lift the headlights. If only the retractor switch is turned ON, the headlights will raise to the upright position, but all lights will be off. An emergency manual retractor knob is located atop each headlight retractor motor.
WARNING
When using the manual control knob, the negative battery cable must be disconnected to prevent accidental movement of the headlight and possible injury.
