CAUTION / NOTICE / HINT

NOTICE:
·

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. As a result, a DTC may be stored.

·

If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.

HINT:

Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.

One Time Recognition: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>ADJUSTMENT (ONE TIME RECOGNITION)

Sequential Recognition: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>ADJUSTMENT (SEQUENTIAL RECOGNITION)


·

The vehicle is equipped with a Supplemental Restraint System (SRS) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the precaution for Supplemental Restraint System.
