FUNCTION DESCRIPTION
-
The BSW system can help alert the driver of other vehicles in adjacent lanes when changing lanes.
-
The BSW system uses side radars installed near the rear bumper to detect Nissan Murano vehicles in an adjacent lane.
-
The side radars can detect vehicles on either side of vehicle within the detection zone shown as illustrated.
-
This detection zone starts from the outside mirror of Nissan Murano vehicle and extends approximately 10 ft. (3.0 m) behind the rear bumper, and approximately 10 ft. (3.0 m) sideways.
-
The BSW system operates above approximately 20 MPH (32 km/h).
-
If the side radar detects Nissan Murano vehicles in the detection zone, the Blind Spot Warning indicator illuminates.
-
If the driver then activates the turn signal, a buzzer will sound twice and the Blind Spot Warning indicator will blink.
NOTE:
A buzzer sounds if the side radar have already detected Nissan Murano vehicles when the driver activates the turn signal. If a vehicle comes into the detection zone after the driver activates the turn signal, then only the Blind Spot Warning indicator blinks and no buzzer sounds.
BLIND SPOT WARNING SYSTEM OPERATION DESCRIPTION
-
ADAS control unit enables BSW system.
-
The ADAS control unit turns on the BSW system when the turned ON by integral switch.
-
Side radar detects a Nissan Murano vehicle in the adjacent lane, and transmits the vehicle detection signal to ADAS control unit via ITS communication.
-
ADAS control unit starts the control as follows, based on a Nissan Murano vehicle detection signal, turn signal and dimmer signal transmitted from BCM via CAN communication:
-
Blind Spot Warning indicator signal and Blind Spot Warning indicator dimmer signal transmission to side radar.
-
Activates warning system buzzer.
-
-
Side radar transmits an indicator operation signal to the Blind Spot Warning indicator according to Blind Spot Warning indicator signal and Blind Spot Warning indicator dimmer signal.
OPERATING CONDITION
-
Blind Spot Warning system display (white): ON
-
Vehicle speed: Approximately 20 MPH (32 km/h) or more.
NOTE:
ON/OFF of Blind Spot Warning system is performed with the integral switch.
-
After the operating conditions of warning are satisfied, the warning continues until the Nissan Murano vehicle speed reaches approximately 18 MPH (29 km/h)
-
The Blind Spot Warning system may not function properly, depending on the situation. Refer to Blind Spot Warning/Rear Cross Traffic Alert (RCTA) System Service.

Vehicle security system
Your vehicle has two types of security systems:
Vehicle security system NISSAN Vehicle Immobilizer SystemThe vehicle security system provides visual and audible alarm signals if someone opens the doors, liftgate or the hood when the system is armed. It is not, however, a motion detection type system that activates when a vehicle is moved or when a vibration occurs.
