Nissan Altima Owners Manual: Warning systems switch (if so equipped)
The warning systems switch is used to temporarily turn off the warning systems (Lane Departure Warning (LDW) and Blind SpotWarning (BSW) systems) that are activated using the settings menu in the vehicle information display.
When the warning systems switch is turned off, the indicator 1 on the switch is off. The indicator will also be off if all of the warning systems are deactivated using the settings menu.
The BSW system will turn on the Blind Spot indicator lights, located inside the vehicle next to the outside mirrors, if a vehicle is located in the detection zone. If the turn signal is activated in the direction of the detected vehicle, a chime sounds twice and the BSW indicator light will flash. For additional information, see “Blind Spot Warning (BSW) System / Lane DepartureWarning (LDW) System” in the “Starting and driving” section.
The LDW system will sound a warning chime and the LDW indicator light (orange) in the vehicle information display blinks to alert the driver if the vehicle is traveling close to either the left or the right of a traveling lane when detected by the camera unit. For additional information, see “Blind Spot Warning (BSW) System / Lane Departure Warning (LDW) System” in the “Starting and driving” section.
