The system is designed to work most effectively when driving in dense traffic on multi-lane highways.
Warning
The system is a supplement to, not a replacement for, a safe driving style and use of the rearview mirrors. It can never replace the driver's attention and responsibility. The responsibility for changing lanes safely always rests with the driver.
Overview
BLIS camera
Indicator lamp
BLIS symbol
Note
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.
Maintenance
In order to work most effectively the BLIS camera lenses2 must be clean. The lenses can be cleaned with a soft cloth or damp sponge. Clean the lenses carefully so that they are not scratched.
Important
The lenses are electrically heated to melt ice or snow. If necessary, brush snow away from the lenses.
