Troubleshooting
A vehicle( in front of your vehicle) is not detected, detection is delayed or detection is lost quickly.
Is the vehicle in front stopped, moving slowly relative to your vehicle or moving extremely slowly? Detection of stopped vehicles, vehicle moving slowly relative to your vehicle, and vehicles moving extremely slowly may be difficult.
Is the windshield dirty or fogged? If the outside of the windshield in front of the stereo camera is dirty, clean the windshield. If the area around the camera lenses is dirty or if it is constantly fogged, contact a SUBARU dealer to have the vehicle inspected.
Is the vehicle in front far away? The maximum detection distance of the stereo camera is approximately 426 ft( 130 m). Detection is not possible if the vehicle is farther away.
Is the vehicle on a curve? The detection range is limited in the horizontal directions when the stereo camera is properly aimed.
Is the vehicle on a road with repeated uphill and downhill grades( such as an overpass), or on a banked road? The detection range is limited in the vertical directions.
Did the vehicle detected in front change? Detection may be delayed after the vehicle in front has changed.
Have water, snow or other substances been kicked up by the vehicle in front as it drives? When water or snow have been kicked up, it may not be possible to detect the vehicle in front.
While Adaptive Cruise Control is active, brake control is operated even though no vehicle in front has been detected.
Is there a vehicle in the neighboring lane? Depending on the road conditions, vehicles in neighboring lanes may be detected as well as a vehicle directly in front.
Are you driving on or near a curve? When driving on a curve, braking control may be activated in response to guardrails, the angle of the steering wheel, or roadside structures.
