Introduction Thank you for purchasing this Acura accessory. Please read this User’s Information Manual carefully before using the backup sensors. Keep this manual in the glove box for future reference. This User’s Information Manual should be considered a permanent part of the vehicle. It should remain with the vehicle at all times and stay with the vehicle when sold. This User’s Information Manual contains important information about the safe operation of the backup sensors.
Important Information Before using the backup sensors, make sure you read and understand the operation and limitations of the system as discussed throughout this manual. • The backup sensors are designed to provide an audible sound when they detect large stationary objects while the vehicle is moving in reverse at low speed. However, all obstacles may not always be sensed.
How the Backup Sensors Work Backup Sensors The sensors are ready for operation when the shift lever is moved into the reverse position. The sensors operate by emitting ultrasonic waves. The sensors calculate the distance to an obstacle by measuring the time that ultrasonic waves take to reflect back from an obstacle.

How the Backup Sensors Work The sensor system is designed to alert you with a buzzer beep when the rear bumper is nearing an obstacle. Corner Sensors: The buzzer beep has three sounds: Buzzer Slow intermittent beeps Quick intermittent beeps Continuous beep Corner Sensor Distance Within 2.0 ft (60 cm) Within 1.3 ft (40 cm) Within 0.8 ft (25 cm) Center Sensor Distance Within 4.9 ft (150 cm) Within 3.3 ft (100 cm) Within 1.
How the Backup Sensors Work The sensors detect the nearest rear obstacle. 7508020E The corner sensor detects the side wall. The sensors may not detect the bumpers of a tall vehicle. 6531060H 8 © 2008 American Honda Motor Co., Inc. - All Rights Reserved.
Limitations The system may not sense thin or low objects or sonic-absorptive materials such as snow, cotton, or sponge. Examples: RECTANGULAR LUMBER POLE CARDBOARD CARTON BICYCLE TIRE • The sensors may not work near a garage door with electrical sensor. • The system cannot sense objects directly under the bumper. The system may not function properly under these conditions: • After the vehicle has been sitting out in hot or cold weather.
Limitations • The sensors are covered with snow, ice, mud, etc. • When the system is affected by electrical equipment or devices generating an ultrasonic wave. 7522010B 5112070K • When the vehicle is on a rough road, on grass, or climbing a hill. • When operating the vehicle in bad weather. 7508040E 10 © 2008 American Honda Motor Co., Inc. - All Rights Reserved.
Operation Before using the backup sensors, become familiar with the types of sounds in relation to the distances between the sensors and the obstacle by parking your vehicle in a garage or parking space. Also confirm the obstacle detecting range of each backup sensor. 1. Apply the parking brake. 2. Turn the ignition switch to ON (II), but do not start the engine yet. 4.
Operation 5. Check that the intermittent warning beeps become quicker as you move the board closer to the sensor. Corner sensors: About 1.3 ft (40 cm) Center sensors: About 3.3 ft (100 cm) 6. Check that the intermittent warning beeps change to a continuous beep as you move the board closer to the sensor. It may stop beeping if you move the board close too quickly. Corner sensors: About 0.8 ft (25 cm) Center sensors: About 1.6 ft (50 cm) 7. 12 Turn the ignition switch to OFF (0).
Care of the Backup Sensors Wipe the sensors clean with a clean cloth. Flush with low-pressure water if the sensors are clogged with mud or dirt. Do not spray high-pressure water against the sensors. LOW-PRESSURE WATER 5112090K © 2008 American Honda Motor Co., Inc. - All Rights Reserved. HIGHPRESSURE WATER (Do not use.
Troubleshooting Perform the following checks if the buzzer does not beep when the vehicle is nearing an obstacle. Symptom 14 Remedy • Clogged sensor with snow or mud • Wipe with a clean cloth or flush with low-pressure water. • Frozen sensor • Melt with lukewarm water. • Extended parking in cold weather or under blazing sun • The backup sensors may not work if the outside air temperature is below -4°F (-20°C) or above 122°F (50°C).
Troubleshooting Troubleshooting With Beeps When you turn the ignition switch to ON (II), and the backup sensor buzzer beeps more than once, there may be a problem with one of the sensors. Corner Sensors Two fast beeps: right sensor is faulty. Three fast beeps: left sensor is faulty. Four fast beeps: right and left sensors are faulty. Center Sensors Two slow beeps: right sensor is faulty. Three slow beeps: left sensor is faulty. Four slow beeps: right and left sensors are faulty.
