WARNING

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

The RCTA function is only an assist and is not a replacement for careful driving. Driver must be careful when backing up, even when using RCTA function. The driver's own visual confirmation of behind you and your vehicle is necessary and be sure there are no pedestrians, other vehicles, etc., before backing up. Failure to do so could cause death or serious injury.

According to conditions, the system may not function correctly. Therefore the driver's own visual confirmation of safety is necessary.

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:

Approaching vehicle Speed
  1. Approximate alert distance

Fast 18 mph (28 km/h) 65 ft. (20 m)
Slow 5 mph (8 km/h) 18 ft. (5.5 m)

■The RCTA function is operational when

  • The RCTA function is turned on.
  • The shift lever 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:

  • Small motorcycles, bicycles, pedestrians, etc.*
  • Vehicles approaching from directly behind
  • Vehicles that the sensors cannot detect due to obstructions

Using the driving support systems

  • Guardrails, walls, signs, parked vehicles and similar stationary objects*
  • Vehicles moving away from your vehicle
  • Vehicles approaching from the parking spaces next to your vehicle*
  • Vehicles backing up in the parking space 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 conditions:
    • 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
    • During bad weather such as heavy rain, fog, snow, etc.
    • When multiple vehicles approach continuously
    • Shallow angle parking
    • When a vehicle is approaching at high speed
    • When parking on a steep incline, such as hills, a dip in the road, etc.
    • Immediately after the RCTA function is turned on
    • Immediately after the engine is started with the RCTA function on.
  • Vehicles that the sensors cannot detect due to obstructions
    • When items such as a bicycle carrier are installed on the rear of the vehicle

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 street
    • 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

Using the driving support systems

  • When there are spinning objects near your vehicle such as the fan of an air conditioning unit
