Toyota Camry: RCTA function - RCTA (Rear Cross Traffic Alert)

Toyota Camry Owner's Manual XV70 (2017-2024) / Driving / Using the driving support systems / RCTA function - RCTA (Rear Cross Traffic Alert)

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.

Using the driving support systems

  1. Approaching vehicles
  2. Detection areas

■ RCTA icon display (if equipped)

When a vehicle approaching from the right or left at the rear of the vehicle is detected, the following will be displayed on the audio system screen.

WARNING

■Cautions regarding the use of the system

There is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. The driver is always responsible for paying attention to the vehicle's surroundings and driving safely.

RCTA function detection areas

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

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:

Using the driving support systems

■The RCTA function is operational when

  • Vehicles without a smart key system: The engine switch is in the "ON" position.

    Vehicles with a smart key system: The engine switch is in IGNITION ON mode.

  • The RCTA function is turned on.
  • The shift lever is in R.
  • The vehicle speed is approximately 5 mph (8 km/h) or less.
  • The approaching vehicle speed is between approximately 5 mph (8 km/h) and 18 mph (28 km/h).

■Conditions under which the system 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 the parking space next to your vehicle*
  • Vehicles that the sensors cannot detect due to obstructions

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*
  • The distance between the sensor and approaching vehicle gets too close

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

■Situations in which the system may not operate properly

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 position above 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 equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or snow plow
  • When backing up on a slope with a sharp change in grade

Using the driving support systems

  • When backing out of a sharp angle parking spot

Using the driving support systems

  • When towing a trailer
  • When there is a significant difference in height between your vehicle and the vehicle that enters the detection area
  • When a sensor or the area around a sensor is extremely hot or cold
  • If the suspension has been modified or tires of a size other than specified are installed
  • If the front of the vehicle is raised or lowered due to the carried load
  • When turning while backing up

Using the driving support systems

  • When a vehicle turns into the detection area

Using the driving support systems

■Situations in which the system may operate even if there is no possibility of a collision

Instances of the RCTA function unnecessary detecting a vehicle and/or object may increase in the following situations:

  • When the parking space faces a street and vehicles are being driven on the street

Using the driving support systems

  • When the distance between your vehicle and metal objects, such as a guardrail, wall, sigh, or parked vehicle, which may reflect electrical waves toward the rear of the vehicle, is short

Using the driving support systems

  • When equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or snow plow
  • When a vehicle passes by the side of your vehicle

Using the driving support systems

  • When a detected vehicle turns while approaching the vehicle

Using the driving support systems

  • When there are spinning objects near your vehicle such as the fan of an air conditioning unit
  • When water is splashed or sprayed a sprinkler
  • Moving objects (flags, exhaust fumes, large rain droplets or snowflakes, rain water on the road surface, etc.)
  • When the distance between your vehicle and a guardrail, wall, etc., that enters the detection area is short
  • Gratings and gutters
  • When a sensor or the area around a sensor is extremely hot or cold
  • If the suspension has been modified or tires of a size other than specified are installed
  • If the front of the vehicle is raised or lowered due to the carried load
