RCTA (Rear Cross Traffic Alert)* *If equipped The RCTA function uses the BSM rear side radar sensors installed behind the rear bumper. This function is intended to assist the driver in checking areas that are not easily visible when backing up. 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. (Cautions regarding the use of the system) To ensure the system can operate properly To ensure the system can operate properly Display RCTA System components Meter control switches Turning the RCTA function on/off. When the RCTA function is disabled, the RCTA OFF indicator illuminates. Outside rear view mirror indicators When a vehicle approaching from the right or left at the rear of the vehicle is detected, both outside rear view mirror indicators will flash. Audio system display If a vehicle approaching from the right or left at the rear of the vehicle is detected, the RCTA icon (RCTA icon display) for the detected side will be displayed on the audio system display. This illustration shows an example of a vehicle approaching from both sides of the vehicle. RCTA buzzer If a vehicle approaching from the right or left at the rear of the vehicle is detected, a buzzer will sound. The buzzer also sounds for approximately 1 second immediately after the RCTA function is turned on. Turning the RCTA function on/off Use the meter control switches to enable/disable the RCTA function. (Changing the meter display) Press or to select . Press or to select “RCTA” and then press . When the RCTA function is disabled, the RCTA OFF indicator (Indicators) illuminates. (Each time the engine switch is turned off then changed to ON, the RCTA function will be enabled automatically.) Note: Outside rear view mirror indicator visibility In strong sunlight, the outside rear view mirror indicator may be difficult to see. Hearing the RCTA buzzer The RCTA buzzer may be difficult to hear over loud noises, such as if the audio system volume is high. RCTA Warning message When “Rear Cross Traffic Alert Unavailable” is shown on the multi-information display Water, snow, mud, etc., may be attached to the rear bumper around the sensors. (BSM (Blind Spot Monitor)*) Removing the water, snow, mud, etc., from the attached to the rear bumper around the sensors to normal. Additionally, the function may not function normally when used in extremely hot or cold environments. Sensor RCTA Rear side radar sensors BSM (Blind Spot Monitor)* RCTA function RCTA function Operation of the RCTA function The RCTA function uses rear side radar sensors to detect vehicles approaching from the right or left at the rear of the vehicle and alerts the driver of the presence of such vehicles by flashing the outside rear view mirror indicators and sounding a buzzer. Approaching vehicles Detection areas of approaching vehicles RCTA icon display 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 display. This illustration shows an example of a vehicle approaching from both sides of the vehicle. RCTA function detection areas The areas that vehicles can be detected in are outlined below. The buzzer can alert the driver of faster vehicles approaching from farther away. Example:
Approaching vehicle speed Approximate alert distance
18 mph (28 km/h) (fast) 65 ft. (20 m)
5 mph (8 km/h) (slow) 18 ft. (5.5 m)
Note: The RCTA function is operational when The RCTA function operates when all of the following conditions are met: The engine switch is in ON. The RCTA function is on. The shift lever is in R. The vehicle speed is less than approximately 5 mph (8 km/h). The approaching vehicle speed is between approximately 5 mph (8 km/h) and 18 mph (28 km/h). Adjusting the buzzer volume The buzzer volume can be adjusted on the multi-information display. The volume of buzzers for the Toyota parking assist-sensor and RCTA function will be adjusted simultaneously. Use the meter control switches to change settings. (Changing the meter display) Press or to select . Press or to select “RCTA” and then press and hold . Select the volume and then press . Each time the switch is pressed, the volume level will change between 1, 2 and 3. Muting a buzzer A mute button will be displayed on the multi-information display when an object is detected. To mute the buzzer, press . The buzzers for the Toyota parking assist-sensor and RCTA function will be muted simultaneously. Mute will be canceled automatically in the following situations: When the shift lever is changed. When the vehicle speed exceeds a certain speed. When the operating function is temporarily canceled. When the operating function is disabled manually. When the engine switch is turned off. 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 a parking space next to your vehicle Vehicles that the sensors cannot detect due to obstructions 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 When backing out of a sharp angle parking spot 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 When a vehicle turns into the detection area 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 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 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 When a detected vehicle turns while approaching the vehicle When there are spinning objects near your vehicle such as the fan of an air conditioning unit When water is splashed or sprayed toward the rear bumper, such as from 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
