BLIS* (Blind Spot Information System)
BLIS (Blind Spot Information System) is a function designed for providing support for the driver when driving in dense traffic on roads with several lanes in the same direction.
BLIS is a driver's aid intended to provide a warning about:
- vehicles in the car's blind spot
- rapidly approaching vehicles in the left and right-hand lanes closest to the car.
The BLIS function CTA (Cross Traffic Alert) is a driver's aid intended to provide a warning about:
- crossing traffic when the car is reversed.
Warning
BLIS is a supplementary aid and does not work in all situations.
BLIS is no substitute for a safe driving style and the use of rearview and door mirrors.
BLIS can never replace the driver's responsibility and attention - it is always the driver's responsibility to change lanes in a safe manner.

The sensors for the BLIS functions are located inside the rear wing/bumper on each side of the car.
- To ensure optimal functionality the areas in front of the sensors must be kept clean.
