Introduction

Thank you for purchasing this Acura accessory.

Please read this Owner’s Manual carefully before using the backup sensors, and keep this manual in the glove box for future reference.

This product is designed to be used exclusively on a Acura TL. Acura is not responsible if the unit is used for any other intended purpose.

This Owner’s Manual should be considered a permanent part of the the vehicle. It should remain with the vehicle at all times and stay with the vehicle when sold.

This accessory should be installed only by a skilled technician who has the proper tools, equipment, and training to correctly and safely add equipment to your vehicle. Installation should not be attempted by “do-it-yourselfers.”

This Owner’s Manual contains important information about the safe operation of the backup sensors. We urge you to read this manual carefully, become familiar with the controls it describes, and follow its recommendations to help make your driving trouble-free and enjoyable.

Important Information

Before using the backup sensors, make sure you read and understand the operation and limitations of the system as discussed below and elsewhere in this manual.

• The backup sensors are designed to provide and audible sound when they detect large stationary objects while the vehicle is moving in reverse at low speed. However, the system may not detect all possible objects depending on their size, shape, or location.

• Even with the backup sensors, the driver is still responsible for making sure the path is clear when operating the vehicle in reverse.

How the Backup Sensors Work

Backup Sensors

The sensors are ready for operation when the shift lever is moved to the reverse position.

Operation of the sensors is dependent upon the ultrasonic waves they emit. They calculate the distance between the sensor and a rear obstacle by measuring the time until the ultrasonic waves reach the sensor after being reflected by the obstacle.

CORNER SENSOR

CENTER SENSOR

CORNER SENSOR

3710040M

The sensors are designed to give you an audible signal when the rear bumper of your vehicle is approaching an obstacle.

• The audible signal has three sounds:

Sound

(Tone Quality) Slow intermittent beeps Quick intermittent beeps

Continuous beep

About 1.5 – 2 feet Intermittent beeps

About 1 – 1.5 feet Quick intermittent beeps

Within 1 foot Continuous beep

Corner Sensors

(High)

Within 2 feet

Within 1.5 feet

Within 1 foot

About 4 – 6 feet Intermittent beeps

2 feet Continuous beep

Center Sensors

(Low)

Within 6 feet

Within 4 feet

Within 2 feet

About 2 – 4 feet Quick intermittent beeps

How the Backup Sensors Work

Corner Sensors:

Center Sensors:

3710050M

The sensors detect the closest rear obstacle.

3710060M

In this example, the corner sensor detects the side wall.

The sensors may not detect the rear bumper of tall vehicles.

3710070M

Limitations

The sensors detect only the closest obstacle. The sensors may detect other obstacles as the vehicle moves.

3710080M

The sensors may not work if the ambient air temperature is below -4°F (-20°C) or above 122°F (50°C).

3710090M

The sensors may not work if the obstacle is an odd shape or made of material that does not reflect ultrasonic waves.

Examples:

CARDBOARD CARTON

CURBSTONE

POLE

TIRE of BICYCLE

RECTANGULAR LUMBER

SMALL or SLENDER TREE

Limitations

The sensors may not sound for the following obstacles or under the following conditions:

• Piece of wire, rope, and net fence

3710100M

• Objects low in height such as curbstone, etc.

3710110M

• Objects that absorb ultrasonic waves, such as soft snow, cotton and sponges

3710120M

The audible signal may sound warning even if there is no obstacle behind the vehicle:

• Droplets of water frozen on the sensor

3710130M

Limitations

3710170M

The audible signal may sound warning even if there is no obstacle behind the vehicle:

• Sensors clogged with snow, dirt or mud

3710140M

The sensors may sound continuously under the following conditions:

• When driving on rough surfaces or gravel roads or in grass, or when stopped on a hill

3710150M

• When the vehicle is equipped with a highpower radio and antenna

3710160M

• When detecting loud noises such as a vehicle horn, a motorcycle’s engine, or air brakes

• When driving in rain or melted snow

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.

1. Check that the parking brake is applied.

2. Turn the ignition switch ON (II). Do not start the engine yet.

3. Move the shift lever to reverse.

4. From behind the vehicle, check that the audible signal sounds by slowly bringing the palm of your hand close to each sensor as described:

For the corner sensors: From 2 feet

For the center sensors: From 6 feet

Confirm that the sound of the corner sensors is different from that of the center sensors.

Confirm the obstacle detecting range of each sensor.

3710180M

5. Check that the intermittent warning beeps become quicker as you bring the palm of your hand closer to the sensor.

For the corner sensors: About 1.5 feet

For the center sensors: About 4 feet

6. Check that the intermittent warning beeps are changed to a continuous beep as you bring the palm of your hand closer to the sensor. The sensor may stop sounding or sound intermittent beeps if you bring the palm of your hand closer too quickly.

For the corner sensors: About 1 foot

For the center sensors: About 2 feet

7. Turn the ignition switch to the LOCK “0” position.

Operation

Daily Inspection

1. Start the engine.

2. Apply the parking brake, and depress the brake pedal. 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.

• If the audible signal keeps sounding, this is

an indication that the sensors are frozen or clogged with mud, dirt, etc.

• The sensors will also keep sounding when

there is an abnormality in the circuit.

Care of the Backup Sensors

Wipe the sensors clean with a clean cloth, or flush with low-pressure water when the sensors are clogged with mud and dirt.

LOW-PRESSURE WATER

3710190M

Do not direct high-pressure water against the sensors.

HIGHPRESSURE WATER (Do not use.)

3710200M

Troubleshooting

Perform the following checks if the audible signal does not sound when the vehicle is approaching an obstacle.

Symptom Remedy

• Clogged sensor with snow or mud

• Frozen sensor

• Extended parking in cold weather or under blazing sun

• Wipe with clean cloth or flush with low-pressure water.

• Melt with lukewarm water

• The backup sensors may not work if the outside air temperature is below -4°F (-20°C) or above 122°F (50°C).

Ask your Acura dealer for advice if the trouble persists.

Take your vehicle to your Acura dealer if you encounter either of these problems:

• The audible signal sounds continuously when the shift lever is in the reverse position, and the sensors are not frozen or clogged with snow or mud.

• The audible signal does not sound when the shift lever is in the reverse position.

Troubleshooting With Beeps

Corner Sensors

Series of two intermittent beeps: right sensor is faulty.

Series of three intermittent beeps: left sensor is faulty.

Series of four intermittent beeps: right and left sensors are faulty.

Center Sensors

Series of three beeps: either or both sensors are faulty.

Be careful not to confuse the sound of the sensors with those of other components or systems.
