an audible warning will sound and

the steering wheel will vibrate (if

equipped).

ORG3070025

śꢀ When the turn signal is turned off or

WARNING

śꢀ The detecting range of the rear

corner radar is determined by a

standard road width, therefore, on a

narrow road, the function may detect

other vehicles in the next next lane

and warn you. In contrast, on a wide

road, the function may not be able to

detect a vehicle driving in the next

lane and may not warn you.

śꢀ When the hazard warning flasher is

on, the collision warning by the turn

signal will not operate.
