HANDLING PRECAUTIONS FOR FORWARD RECOGNITION CAMERA

(a) When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle and a DTC may be stored.

(b) When the forward recognition camera has been replaced with a new one, make sure to clear all stored vehicle control history of each system and the forward recognition camera beam axis alignment data.

HINT:

Forward recognition camera beam axis alignment can be performed by using "One Time Recognition", "Driving Adjustment" or "Camera Axis Adjustment Value Write".

PRECAUTION FOR AUTOMATIC HIGH BEAM SYSTEM

(a) General Description

The automatic high beam system is a system that helps ensure visibility by automatically turning the high beam headlights on and off. Additionally, due to control limitations of the automatic high beam system, it may be necessary to manually turn the high beam headlights on and off. For safety reasons, make sure to turn the high beam headlights on and off manually according to the driving conditions.

(b) Conditions Unsuitable for Using Automatic High Beam System

Under the following conditions, the automatic high beam system might not detect other vehicles or lights correctly, or the high beam headlights might cause glare or flash pedestrians or the occupants of other vehicles. Manual operation should be considered.
