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:
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 to 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 the indicator light is 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
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 may
flash or the
indicator
light may
illuminate.
Do not drive on these types of roads.
This is not a malfunction. 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 four 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 may
flash or both the
and
indicator
lights may illuminate.
Restart the engine after driving onto a stable surface.
