3. HANDLING THE RADAR SENSOR

(a) One blind spot monitor sensor is installed inside the left and right sides of the vehicle rear bumper respectively. Observe the following to ensure that the blind spot monitor can function correctly.

(1) Keep the sensor and its surrounding area on the bumper clean at all times.

(2) Do not subject surrounding area on the bumper to a strong impact. If the sensor moves even slightly off position, the system may malfunction and vehicles that enter the detection area may not be detected. If surrounding area has been subjected to a strong impact, inspect the sensor and surrounding area.

(3) Do not disassemble the sensor.

(4) Do not attach accessories or stickers to the sensor or surrounding area on the bumper.

(5) Do not modify the sensor or surrounding area on the bumper.

(6) Do not paint the rear bumper any color other than an official Toyota color.

(7) Do not apply strong impacts to the sensor or drop it, as it is a high-precision device.

(8) Do not reuse a sensor that has been dropped or subjected to a strong impact.
