This system senses upper body motion (based on wheel speed information) and controls engine torque and four wheel brake pressure. This will enhance ride comfort in effort to restrain uncomfortable upper body movement when passing over undulated road surfaces . This system comes into effect above 25 mph (40 km/h).
When the VDC OFF switch is used to turn off the VDC system, the Active Ride Control is also turned off.

Active ride control
When brake control of Active Ride Control is operated and the “Chassis Control” mode is selected in the trip computer, the Active Ride Control graphics are shown in the vehicle information display. For additional information, refer to “Trip Computer” in the “Instruments and Controls” section of this manual.
If the chassis control warning message appears in the vehicle information display, it may indicate that the Active Ride Control is not functioning properly. Have the system checked by a NISSAN dealer as soon as possible.
When the Active Ride Control is operating, you may hear noise and sense slight deceleration.
This is normal and indicates that the Active Ride Control is operating properly.
