Nissan Altima (L33) 2013-2018 Owners Manual: BSW/LDW automatic deactivation
When dirt, rain or snow cannot be removed by the automatic washer and blower and accumulates on the camera, making it impossible to detect the vehicles or the lane markers, the BSW and/or LDW system will be turned off automatically.
The BSW light (white) and/or LDW light (white) will blink, and the “Unavailable : Clean rear camera” will appear in the vehicle information display.
Action to take:
If the message appears, park the vehicle in a safe place, clean the camera unit with a soft cloth.
Then turn off and restart the engine.
When the BSW and/or LDW system malfunctions, they will be turned off automatically, the BSW light (orange) and/or LDW light (orange) will illuminate and “Malfunction: Please see owners manual” will appear in the vehicle information display.
Action to take:
Stop the vehicle in a safe location, turn off and restart the engine. If the BSW light (orange) and/or the LDW light (orange) continues to illuminate, have the BSW and/or LDW system checked by a NISSAN dealer.
