The RCTA functions when your vehicle is in reverse. It can detect

uses radar sensors to alert the driv er of the other vehicle’s existence
through flashing the outside rear vi ew 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.
