Forward Looking Radar (FLR)
Forward Looking Radar (FLR) is connected to Forward Sensing Module (FSM). Information transfer between Forward Looking Radar (FLR) and Forward Sensing Module (FSM) takes place via local CAN-communication. Forward Looking Radar (FLR) is located in the front of the vehicle (behind the grill).
Forward Looking Radar (FLR) is only found in vehicles equipped with adaptive cruise control, collision warning, automatic braking/brake support, and distance control.
Forward Looking Radar (FLR) is used to identify and range targets (vehicles ahead) Forward Looking Radar (FLR) ranges both stationary, oncoming, as well as targets that move in the same direction as your own vehicle. When a target is detected Forward Looking Radar (FLR) senses the target's speed, distance, and angle to the target in relation to your own vehicle.
When replacing as well as downloading software of Forward Looking Radar (FLR), the new unit must be calibrated using the diagnostics tool.
Note! Accessories or other objects such as auxiliary lights may not be installed in front of the grill.
Indicator, visual collision warning
Indicator, visual collision warning consists of 12 LEDs in three groups. The LEDs are directly connected to the Forward Sensing Module (FSM).
The indicator is used to visually warn the driver that a collision is imminent, in order to reduce the risk of, or prevent, collision. The indicator is also used to visually inform the driver when the time interval to the vehicle in front is shorter than the set interval.
The visual collision warning indicator is located at the upper edge of the dashboard on the driver's side.
The Forward Sensing Module (FSM) controls the light intensity at the visual collision warning indicator via pulse width modulation. The three groups of LEDs are separately connected to the Forward Sensing Module (FSM), this means that the Forward Sensing Module (FSM) can control each group of LEDs individually.
The indicator has an internal temperature sensor. The task of the temperature sensor is to protects the electronics. At temperatures above 100 °C / 212 °F the indicator does not light the LEDs when the Forward Sensing Module (FSM) requests it. When this has occurred, the Forward Sensing Module (FSM) prevents the indicator from being lit for a further 10 minutes.
Note! The visual warning signal may temporarily be out of order at high passenger compartment temperature caused by, e.g., strong sun light. If this happens, the warning sound is activated even if it is deactivated in the menu system.
Forward facing camera
The front facing camera is a sensor that is connected to the Forward Sensing Module (FSM). Information is sent from the camera to the Forward Sensing Module (FSM) in the form of an analogue video signal.
The camera is located at the upper edge on the inside of the windscreen, by the rear view mirror.
The forward facing camera is used to provide the control module with information about stationary and moving objects, as well as to identify and measure road lines.
To prevent condensation forming on the windscreen in front of the camera there is a heating element that is controlled via the control module.
When replacing forward-facing camera or Forward Sensing Module (FSM), the new unit must be calibrated using the diagnostics tool.
This must also take place when downloading software for control module in case fault code FSM-500154 is set.
Note! The camera has limitations similar to the human eye, that is, it "sees" worse in the dark, heavy snowfall or rain and in thick fog. Under such conditions camera-dependent functions may be severely reduced or temporarily deactivated.Even strong backlight, reflections from the road, snow or icy road, dirty road or unclear lane markings may reduce the function when the camera is used to read off the road as well as detect pedestrians and other vehicles. At very high temperatures the camera is temporarily turned off for approx. 15 minutes after engine start to protect the camera function.
Note! If the display shows the message Windshield Sensors Covered, this means that the camera sensor is blocked and cannot detect pedestrians, vehicles, or lane markings in front of the car.
