BLIS is a driver’s 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.
- Zone in the blind spot
- Zone for quickly approaching vehicle
The system is designed to react when:
- your car is overtaken by other vehicles
- another vehicle is approaching your own car at speed.
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 right or left 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 more intense light. BLIS is active when the driver’s vehicle is traveling at a speed above 12 km/h (7 mph). If passing vehicles drive more than 15 km/h (9 mph) faster than the driver’s vehicle, BLIS will not react.
Note
The lamp illuminates 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.
