2008 Toyota Prius BaseFACTORY OEM SERVICE PROCEDURE

System Outline

This system adjusts the illuminating angle to match changes in the vehicle height and axle distance, based on the information of the vehicle height detected by the height sensors installed at the rear of the vehicle and on information of the vehicle speed and acceleration received from the VSC system. This information is used to operate the reflector with the determined illuminating angle via actuators in order to always keep the beam axis constant.

If an error occurs in this system, the headlight beam level control warning light in the combination meter lights up and warning buzzer goes of to warn the driver.
