XC90 FWD L6-3.2L VIN 96 B6324S2 (2010)
Day/Night mode
In daylight the system reacts to the shape of the surrounding vehicles. The system is designed to help detect motor vehicles such as cars, trucks, buses
and motorcycles.
In darkness the system reacts to the headlamps of surrounding vehicles. If the headlamps of surrounding vehicles are not switched on then the system
does not detect the vehicles. This means for example that the system does not react to a trailer without headlamps which is towed behind another vehicle
When is BLIS operational
The system is "default on" (set to be on each time the vehicle is started). At vehicle speeds of 6 mph (10 km/h) and above the system will indicate
another vehicle in the blind spot.
The system is designed to indicate another vehicle in the blind spot if:
- you pass another vehicle at a speed of up to 6 mph (10 km/h) faster than the other vehicle.
- another vehicle passes you travelling up to 43 mph (70 km/h) faster than you are travelling.
It is possible to stop the BLIS indications to the driver by selecting the "BLIS OFF/ON button".
When BLIS "OFF" is selected the LED in the button goes out and a text message is shown on the Driver Information Module (DIM).
IMPORTANT NOTE: this only turns off the communication to the driver, the system is still be operating in the background.
If there is a need to reset the system you need to turn the engine off and restart.
Technical description
BLIS is a camera based system; the camera's take 25 pictures per second and compares them to a pre-determined algorithm (step-by-step
problem-solving procedure) based on picture size/shape and delta (changes in) velocity.
False indications
The system detection algorithm is designed to read sharp contoured shapes that are in the detection area (cars, busses, trucks, motorcycles). Light
reflections and shadows can trigger warnings since the camera can't always distinguish these from real objects. Advise the customer the system is
operating as intended. Inform the customer why and how the continuous light from one of the two indicators (LED's) is present and that BLIS is an
information system.
