Toyota Prius: RCD (Rear Camera Detection) function

• System components
• When a pedestrian is detected

System components

When the Toyota Prius is in reverse, its rear camera detection function actively scans the area behind the vehicle for pedestrians within its detection range. Upon detecting a pedestrian, the system alerts the driver with both an audible buzzer and an icon displayed on the Multimedia Display. This dual alert system ensures that the driver is promptly informed of the pedestrian's presence, enhancing safety by helping to prevent potential collisions during backing maneuvers.

WARNING

Cautions regarding the use of the system

The recognition and control capabilities for this system are limited.

The driver should always drive safely by always being responsible without over relying on the system and have a understanding of the surrounding situations.

To ensure the system can operate properly

Observe the following, otherwise there is the danger that could lead to an accident.

• Always clean the camera without damaging it.
• Do not install market electronic parts (such as Illuminated license plate, fog lamps, etc.) in the camera vicinity.

WARNING

• Do not subject the camera vicinity to strong impacts. If the vicinity is subjected to a strong impact, have the vehicle inspected by your Toyota dealer.
• Do not disassemble, remodel or paint the camera.
• Do not attach accessories or stickers to the camera.
• Do not install market protection parts (bumper trim, etc.) to the rear bumper.
• Maintain suitable tire air pressure.
• Make sure the back door is completely closed.

RCD function is turned off

In the following situations the system turns off. The RCD function may not operate properly and thus there is the danger that an accident may occur.

• The contents mentioned above are not observed.
• Suspensions other than genuine parts are installed.

Turning the RCD function on/off

The RCD function can be enabled/disabled on of the multi-information display.

When the RCD function is disabled, the driving assist information indicator  illuminates, and a message is displayed on the multiinformation display.

Each time the power switch is turned off then changed to ON, the RCD function will be enabled automatically.

When a pedestrian is detected

If a pedestrian is detected behind the Toyota Prius (2024-2025) or if the rear camera detects a pedestrian approaching from behind, the system alerts the driver with both an audible buzzer and a visual display on the Multimedia Display. This alert prompts the driver to exercise caution, ensuring awareness of pedestrian presence to enhance safety during vehicle maneuvers.

1. If a pedestrian is detected in area Buzzer: Sounds repeatedly Pedestrian detection icon: Blinks
2. If a pedestrian is detected in area Buzzer (When the vehicle is stationary): Sounds 3 times Buzzer (When the vehicle is backing up, when a pedestrian approaches the rear of the vehicle): Sounds repeatedly Pedestrian detection icon: Blinks
3. If the system determines that your vehicle may collide with a pedestrian in area Buzzer: Sounds repeatedly Pedestrian detection icon: Blinks

The rear camera detection function is operational when

• The power switch is in ON.
• RCD function is on.
• The shift position is in R.
• Advanced Park is not operating (vehicles with Advanced Park)

Setting the buzzer volume

The buzzer volume of the intuitive parking assist, RCTA, and RCD can be adjusted all together on of the multi-information display.

Muting a buzzer temporarily

When an object is detected, the temporary mute switch is displayed on the Multimedia Display.

Select the switch to mute a buzzer of the intuitive parking assist, RCTA, and RCD all together.

Mute will be automatically canceled in the following situations:

• When the shift position is changed.
• When the vehicle speed exceeds a certain speed.
• When there is a malfunction in a sensor or the system is temporarily unavailable.
• When the operating function is disabled manually.
• When the power switch is turned off.

Situations in which the system may not operate properly

• Some pedestrians, such as the following, may not be detected by the rear camera detection function, preventing the function from operating properly:

• Pedestrians who are bending forward or squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly appear from the shadow of the vehicle or a building
• Pedestrians who are riding moving objects such as a bicycle or skateboard
• Pedestrians wearing oversized clothing such as a rain coat, long skirt, etc., making their silhouette obscure
• Pedestrians whose body is partially hidden by an object, such as a cart or umbrella
• Pedestrians which are obscured by darkness, such as at night

• In some situations, such as the following, pedestrians may not be detected by the rear camera detection function, preventing the function from operating properly:

• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is obscured (dirt, snow, ice, etc. are attached) or scratched
• When a very bright light, such as the sun, or the headlights of another vehicle, shines directly into the rear camera
• When backing up in a place where the surrounding brightness changes suddenly, such as at the entrance or exit of a garage or underground parking lot
• When backing up in a dim environment such as during dusk or in an underground parking lot
• When the camera position and direction are deviated
• When a towing hook is attached
• When towing with the vehicle
• When water droplets are flowing on the camera lens
• When the vehicle height is extremely changed (nose up, nose down, etc.)
• When tire chains or an emergency tire puncture repair kit are used
• When the suspension has been lowered or tires that have a different size than the genuine tires are installed
• When an aftermarket electronic part (backlit license plate, fog light, etc.) is installed near the rear camera
• If a bumper protector, such as an additional trim strip, is installed to the rear bumper

Situations in which the system may operate unexpectedly

• Even though there are no pedestrians in the detection area, some objects, such as the following, may be detected, possibly causing the rear camera detection function to operate

• Three dimensional objects, such as a pole, traffic cone, fence, or parked vehicle
• Moving objects, such as a car or motorcycle
• Objects moving toward your vehicle when backing up, such as flags or puddles (or airborne matter, such as smoke, steam, rain, or snow)
• Cobblestone or gravel roads, tram rails, road repairs, white lines, pedestrian crossings or fallen leaves on the road
• Metal covers (gratings), such as those used for drainage ditches
• Objects reflected in a puddle or on a wet road surface
• Shadows on the road

• In some situations, such as the following, the rear camera detection function may operate even though there are no pedestrians in the detection area.

• When backing up toward the roadside or a bump on the road
• When backing up toward an incline/decline
• When the vehicle height is extremely changed (nose up, nose down, etc.)
• If a bumper protector, such as an additional trim strip, is installed to the rear bumper
• When an aftermarket electronic part (backlit license plate, fog light, etc.) is installed near the rear camera
• If the orientation of the rear camera has been changed due to a collision or other impact, or removal and installation
• If a towing eyelet is installed to the rear of the vehicle
• When towing with the vehicle
• When water is flowing over the rear camera lens
• When the rear camera is obscured (dirt, snow, ice, etc. are attached) or scratched
• If there is a flashing light in the detection area, such as the emergency flashers of another vehicle
• When tire chains or an emergency tire puncture repair kit are used.

• Situations in which the rear camera detection function may be difficult to notice

• The buzzer may be difficult to hear if the surrounding area is noisy or the audio system volume is high.
• If the temperature in the cabin is extremely high or low, the Multimedia Display may not operate correctly.
