RCTA (Rear Cross Traffic Alert) function* *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 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. 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 If a vehicle is detected as approaching from the left or right behind the vehicle, both outside rear view mirror indicators will blink and a buzzer will sound. Audio system screen 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 screen. This illustration shows an example of a vehicle approaching from both sides of the vehicle. Driving assist information indicator When the RCTA is off,  “ Rear Cross Traffic Alert OFF” will be displayed on the multi-information display. Switches RCTA switch Turning the RCTA function on/off The RCTA can be enabled/disabled on (4.2-inch display) or (7-inch display) of the multi-information display. (Customizable features) When the RCTA function is off, the driving assist information indicator (Indicators) will illuminate. At this time, " Rear Cross Traffic Alert OFF" will be displayed on the multi-information display. Each time the engine switch is turned to ON, the RCTA is enabled. 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. 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 screen. Example: Vehicles are 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
34 mph (56 km/h) (fast) 131 ft. (40 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 9 mph (15 km/h). The approaching vehicle speed is between approximately 5 mph (8 km/h) and 34 mph (56 km/h). Setting the buzzer volume The buzzer volume can be adjusted on the multi-information display. The volume of the RCTA buzzer can be adjusted on (4.2-inch display) or (7-inch display) of the multi-information display. (Customizable features) 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 Immediately after the RCTA function is turned on Immediately after the engine is started with the RCTA function on When the sensors cannot detect a vehicle due to obstructions 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
