are open or closed, resulting in an unexpected accident.
Do not disassemble, damage, lift or pull on the sensor.
●
Do not select the sensor while driving.
●
Do not wet or spill water on the sensor.
●
Do not drop anything on or allow anything to hit against the sensor. Do not sub-

●
that faces the driver.
Do not place any objects in front of the side of the sensor that faces the driver or
●
cover the sensor.
