Auto High-Beam (High-Beam Support System) Description - Overview

Overview 

The system operates by switching the high beam and low beam automatically depending on the road condition of vehicles running ahead and opposite vehicles, using the multipurpose camera unit.

Operating Conditions

• The combination light switch is in the AUTO position.
• The headlight low beam is illuminated.
• White and red light sources are not detected ahead.
• 2 or more streetlights have not been detected.
• The vehicle speed is above 25 mph (40 km/h).
• There is no refracted light due to fog or other weather conditions.
• There is no manual operation input of the combination light switch.

  NOTE:  Weather and road conditions (undulation, curve, or environment illuminance etc.) may affect system operation.

Conditions When the System Stops Operating 

The system stops operation under the following conditions.

• When the combination light switch is turned to other than the AUTO position.
• If the high beam or pass position of the combination switch was operated.
• When the vehicle speed is low:

  • -

    Less than 15 mph (24 km/h) condition continues more than four seconds.
