HANDLING THE RADAR SENSOR

(a) Blind spot monitor sensors are installed behind the left and right sides of the rear bumper respectively. Observe the following to ensure the blind spot monitor can function correctly.

(1) Keep the sensors and the surrounding areas on the rear bumper clean at all times.

(2) Do not subject a sensor or its surrounding area on the rear bumper to a strong impact. If a sensor is moved even slightly off position, the system may malfunction and vehicles may not be detected correctly. In the following situations, inspect the sensor and surrounding area.

• A sensor or its surrounding area is subjected to a strong impact.
• If the surrounding area of a sensor is scratched or dented, or part of them has become disconnected.

(3) Do not disassemble the sensor.

(4) Do not install accessories in the blind spot monitor sensors and the rear bumper near the blind spot sensors and apply any sticker (including a transparent one) and aluminum tape.

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

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

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

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

SENSOR EXPRESSIONS
