BLIS

Overview

BLIS (Blind Spot Information System) is a func-

tion designed for providing support for the driver

when driving in dense traffic on roads with sev-

eral lanes in the same direction.

BLIS is a driver's aid intended to provide a warn-

ing about:

• vehicles in the car's blind spot

• quickly approaching vehicles in the left and

right lanes closest to the car.

Keep this surface clean - also on the left-hand side.
