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 supplemen-
tary 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 cor-
rectly under certain conditions, the
driver’s own visual confirmation of safety
is necessary. Over reliance on this func-
tion may lead to an accident resulting
death or serious injury.
