Toyota CH-R Owners Manual: RCTA function

The RCTA functions when your vehicle is in reverse. It can detect other vehicles approaching from the right or left rear of the vehicle. It uses radar sensors to alert the driver of the other vehicle's existence through flashing the outside rear view mirror indicators and sounding a buzzer.

WARNING

■Cautions regarding the use of the function The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.

The RCTA function is only a supplementary function which alerts the driver that a vehicle is approaching from the right or left at the rear of the vehicle.

As the RCTA function may not function correctly under certain conditions, the driver's own visual confirmation of safety is necessary. Over reliance on this function may lead to an accident resulting death or serious injury.

RCTA function detection areas

The areas that vehicles can be detected in are outlined below.

Toyota CH-R. Using the driving support systems

To give the driver a more consistent time to react, the buzzer can alert for faster vehicles from farther away.

Example:

Toyota CH-R. Using the driving support systems

■The RCTA function is operational when The RCTA function operates when all of the following conditions are met:

  • The BSM system is set to on.
  • The shift position is in R.
  • Vehicle speed is less than approximately 5 mph (8 km/h).
  • Approaching vehicle speed is between approximately 5 mph (8 km/h) and 18 mph (28 km/h).

■Conditions under which the RCTA function will not detect a vehicle The RCTA function is not designed to detect the following types of vehicles and/or objects:

  • Vehicles approaching from directly behind
  • Vehicles backing up in a parking space next to your vehicle
  • Vehicles that the sensors cannot detect due to obstructions

Toyota CH-R. Using the driving support systems

  • Guardrails, walls, signs, parked vehicles and similar stationary objects*
  • Small motorcycles, bicycles, pedestrians, etc.*
  • Vehicles moving away from your vehicle
  • Vehicles approaching from the parking spaces next to your vehicle*

*: Depending on the conditions, detection of a vehicle and/or object may occur.

■Conditions under which the RCTA function may not function correctly

  • The RCTA function may not detect vehicles correctly in the following situations:
    • When the sensor is misaligned due to a strong impact to the sensor or its surrounding area
    • When mud, snow, ice, a sticker, etc., is covering the sensor or surrounding area on the rear bumper
    • When driving on a road surface that is wet with standing water during bad weather, such as heavy rain, snow, or fog
    • When multiple vehicles are approaching with only a small gap between each vehicle
    • When a vehicle is approaching at high speed
    • When backing up on a slope with a sharp change in gradeToyota CH-R. Using the driving support systems
    • When backing out of a shallow angle parking spotToyota CH-R. Using the driving support systems
    • Immediately after the RCTA function is set to on
    • Immediately after the engine is started with the RCTA function is set to on
    • When the sensors cannot detect a vehicle due to obstructionsToyota CH-R. Using the driving support systems
  • Instances of the RCTA function unnecessarily detecting a vehicle and/or object may increase in the following situations:
    • When a vehicle passes by the side of your vehicle
    • When the parking space faces a street and vehicles are being driven on the streetToyota CH-R. Using the driving support systems
    • When the distance between your vehicle and metal objects, such as a guardrail, wall, sign, or parked vehicle, which may reflect electrical waves toward the rear of the vehicle, is short
