PRECAUTION BEFORE SERVICING
(a) Make sure to turn the pre-collision system off in the following situations, as it may operate unexpectedly or may not operate when necessary.
TROUBLESHOOTING PRECAUTIONS
(a) If a terminal contact malfunction or part installation problem occurs, removal and reinstallation of the suspected part may return the system to normal. However, be aware that the normal condition may only be temporary.
(b) Before disconnecting connectors or removing/installing parts, determine the malfunctioning area by checking and writing down the vehicle conditions (output DTCs, etc.) at the time the malfunction occurred.
(c) Be sure to check for DTCs related to other systems. The pre-collision system may be influenced by malfunctions in other systems.
HANDLING PRECAUTIONS
(a) When removing and installing ECUs, sensors, switches or other pre-collision system related parts, perform the following:
REPLACEMENT PRECAUTIONS
(a) MILLIMETER WAVE RADAR SENSOR ASSEMBLY:
(1) When replacing the millimeter wave radar sensor assembly, replace it with a new one.

(c) WINDSHIELD GLASS:
(1) When replacing the windshield glass of a vehicle equipped with a forward recognition camera, make sure to use a Toyota genuine part. If a non-Toyota genuine part is used, the forward recognition camera 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.
(2) Do not attach stickers, including transparent stickers, or other items to the outer side of the windshield glass assembly within the area in front of the forward recognition camera.
