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 rea r of the vehicle.
As the RCTA function may not function correctly under certain c onditions,
the driver’s own visual confirmation of safety is necessary. Ov er reliance on
this function may lead to an accident resulting death or seriou s injury.
