Caution / Notice / Hint

NOTE:

When replacing the pre-collision city sensor, replace it with a new one and be sure to initialize the settings. If a pre-collision city sensor which was installed to another vehicle is used, the information stored in the pre-collision city sensor will not match the information from the vehicle and, as a result, a DTC may be stored.
If the pre-collision city sensor has been replaced, or the windshield glass has been replaced or removed/installed, be sure to perform Pre-collision City Sensor Learning (Refer to ADJUSTMENT [11/2015 - ] ).
When replacing the windshield glass of a vehicle equipped with a pre-collision city sensor, make sure to use a Toyota genuine part. If a non-Toyota genuine part is used, the pre-collision city sensor may not be able to be installed due to a missing bracket or the pre-collision system may not operate properly due to a difference in the transmissivity or black ceramic border.
Pre-collision city sensor optical axis may deviate if the vehicle is driven on a banked road, such as a racetrack. This deviation can be corrected by driving the vehicle on a normal road for a while.
Pre-collision city sensor optical axis may deviate when the vehicle is overloaded or the wheel alignment (toe-in) is incorrect. The pre-collision city sensor optical axis can be corrected by decreasing the load on the vehicle or adjusting the toe-in.
