The BLIS1 function is intended to help the driver detect vehicles diagonally behind and to the side of the car so as to provide assistance in heavy traffic on roads with several lanes in the same direction.
BLIS is a driver aid intended to give a warning of:
  • vehicles in the car's blind spot
  • quickly approaching vehicles in the left and right lanes closest to the car.

The BLIS function is active at speeds above 10 km/h (6 mph).

The system is designed to react when:
  • your car is overtaken by other vehicles
  • another vehicle is quickly approaching your car.

When BLIS detects a vehicle in Zone 1 or a quickly approaching vehicle in Zone 2, the indicator lamp on the door mirror on the affected side illuminates with a constant glow. If the driver activates the direction indicator on the same side as the warning, the indicator lamp will change over from a constant glow to flashing with a more intense light.


The lamp illuminates on the side of the car where the system has detected the vehicle. If the car is overtaken on both sides at the same time then both lamps illuminate.


  • The BLIS function is supplementary driver support intended to facilitate driving and make it safer – it cannot handle all situations in all traffic, weather and road conditions.
  • The responsibility for changing lanes safely and using good judgement always rests with the driver.
  • BLIS is not a substitute for the driver's attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
