Introduction Thank you for purchasing this Honda accessory. Please read this User’s Information carefully before using the backup sensors, and keep this Information in the glove box for future reference. This product is designed to be used exclusively on a Honda CR-V. Honda is not responsible if the unit is used for any other intended purpose.
Important Information Before using the backup sensors, make sure you read and understand the operation and limitations of the system as discussed throughout this Information. • 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.
Backup Sensors The sensors are ready for operation when the shift lever is moved to the reverse position. The sensors operate by emitting ultrasonic waves. They calculate the distance between the rear bumper and an obstacle by measuring the time the ultrasonic waves take to reach the sensor after being reflected by an obstacle.
How the Backup Sensors Work The sensors are designed to emit an audible signal when the rear bumper or the spare tire approaches an obstacle. Corner Sensors: Corner Sensors Distance from Sound bumper Within 2.0 ft Continuous beep (60 cm) Center Sensors: •...
Limitations The sensors may not work if the obstacle is an odd shape or made of material that does not reflect ultrasonic waves. Examples: POLE CARDBOARD CARTON SMALL TREE SOFT SNOW AND OTHER ABSORBENT OBJECTS CURBSTONE WIRE, ROPE, AND NET FENCE The sensors may not work if the ambient air temperature is below -4°F (-20°C) or above 122°F (50°C).
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 actually backing your vehicle into a garage or parking space. Also confirm the obstacle detecting range of each backup sensor.
Check that the intermittent warning beeps become quicker as you bring the palm of your hand closer to the sensor. For the center sensors: About 4.3 feet (130 cm) Check that the intermittent warning beeps change to a continuous beep as you bring the palm of your hand closer to the sensor.
Daily Inspection Turn the ignition switch to ON (II), and apply the parking brake. Depress the brake pedal, and move the shift lever to the reverse position. Check that the audible signal sounds for about one second. • The sensors are normal if the audible signal sounds for about one second.
Troubleshooting Perform the following checks if the audible signal does not sound when the vehicle is approaching an obstacle. Symptom • Clogged sensor • Wipe with a clean cloth or flush with snow or mud with low-pressure water. • Frozen sensor •...
Troubleshooting Troubleshooting With Beeps When you turn the ignition switch to ON (II), and the backup sensor signal sounds more than once, there may be a problem with one of the sensors. Corner Sensors Two slow beeps: right sensor is faulty. Three slow beeps: left sensor is faulty.
