Nissan LEAF 2023 Owners Manual
9.22.10. Ultrasonic Parking Sensors (where fitted)
Ultrasonic sensors in the vehicle’s front and rear bumpers (or rear bumper only), measure the distances between the vehicle and an obstacle when reversing. When reverse gear is engaged, a top view of the vehicle is shown in the Vehicle Information Display and the system sounds a tone. On the display the distances (1 meter and less) to objects are shown. If the object(s) get(s) closer to the vehicle, colours change from green over yellow to red and the interval between tones shortens. If the text [STOP] is shown, stop the vehicle before actually touching the object.
The parking sensor (sonar) system is a convenience but it is not a substitute for proper parking.
The driver is always responsible for safety during parking and other manoeuvres. Always look around and check that it is safe to do so before parking.
Read and understand the limitations of the parking sensor (sonar) system as contained in this section. The colours of the sensor indicator indicates different distances to the object.
Inclement weather or ultrasonic sources such as an automatic car wash, a truck's compressed-air brakes, horn sound, or a pneumatic drill may affect the function of the system; this may include reduced performance or a false activation.
The parking sensor (sonar) system is designed as an aid to the driver in detecting large stationary objects to help avoid damaging the vehicle.
The parking sensor (sonar) system is not designed to prevent contact with small or moving objects. Always move slowly. The system will not detect small objects below the bumper, and may not detect objects close to the bumper or on the ground.
The parking sensor (sonar) system may not detect the following objects: fluffy objects such as snow, cloth, cotton, glass-wool, etc.; thin objects such as rope, wire and chain, etc.; or wedge-shaped objects.
Excessive noise (such as audio system volume or an open vehicle window) will interfere with the tone and it may not be heard.
Keep the surface of the sonar sensors (located on the front and rear bumper fascia) free from accumulations of snow, ice and dirt. Do not scratch the surface of the sonar sensors when cleaning. If the sensors are covered, the accuracy of the sonar function will be diminished.
The front and rear parking sensors (sonar) detect the distance between the vehicle and the obstacle by detecting the sound wave reflected from the surface of an obstacle. When there is a sound such as horn, or an ultrasonic source (such as parking sensors of other vehicles) around the vehicle, the sensor (sonar) may not detect objects properly.
