The VDC system uses various sensors to monitor driver inputs and vehicle motion. Under certain driving conditions, the VDC System helps to perform the following functions:
Controls brake pressure to reduce wheel slip on one slipping drive wheel so power is transferred to a non slipping drive wheel on the same axle.
Controls brake pressure and engine output to reduce drive wheel slip based on vehicle speed (traction control function).
Controls brake pressure at individual wheels and engine output to help the driver maintain control of the vehicle in the following conditions:
The VDC system can help the driver to maintain control of the vehicle, but it cannot prevent loss of vehicle control in all driving situations.
When the VDC system operates, the indicator in the instrument panel flashes so note the following:
For additional information, refer to "Slip indicator light" and "Vehicle Dynamic Control (VDC) OFF indicator light" in the "Instruments and controls" section of this manual.
If a malfunction occurs in the system, the indicator light comes on in the instrument panel.
The VDC system automatically turns off when these indicator lights are on.
The VDC OFF switch is used to turn off the VDC system. The indicator illuminates to indicate the VDC system is off.
When the VDC switch is used to turn off the system, the VDC system still operates to prevent one drive wheel from slipping by transferring power to a non slipping drive wheel. The indicator flashes if this occurs. All other VDC functions are off and the indicator will not flash.
The VDC system is automatically reset to on when the ignition switch is placed in the OFF position then back to the ON position.
The computer has a built in diagnostic feature that tests the system each time you start the engine and move the vehicle forward or in reverse at a slow speed. When the self-test occurs, you may hear a clunk noise and/or feel a pulsation in the brake pedal. This is normal and is not an indication of a malfunction.
WARNING
The VDC system is designed to help the driver maintain stability but does not prevent accidents due to abrupt steering operation at high speeds or by careless or dangerous driving techniques.
Reduce vehicle speed and be especially careful when driving and cornering on slippery surfaces and always drive carefully.
If suspension parts such as shock absorbers, struts, springs, stabilizer bars, bushings and wheels are not NISSAN recommended for your vehicle or are extremely deteriorated, the VDC system may not operate properly. This could adversely affect vehicle handling performance, and the indicator light may flash or illuminate.
Restart the engine after driving onto a stable surface.
Brake force distribution
During braking while driving through turns, the system optimizes the distribution of force to each of the front and rear wheels depending on the radius of the turn.
WARNING
Reduce vehicle speed and be especially careful when driving and cornering on slippery surfaces and always drive carefully.
If suspension parts such as shock absorbers, struts, springs, stabilizer bars, bushings and wheels are not NISSAN recommended for your vehicle or are extremely deteriorated, the VDC system may not operate properly. This could adversely affect vehicle handling performance, and the indicator light may flash or illuminate.
