VEHICLE DYNAMIC CONTROL (VDC) SYSTEM
The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
tion. If the computer senses a malfunc-
tion, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system then
operates normally, but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked. It is recommended you
visit a NISSAN dealer for this service.

The road may be slippery or the
system may determine some action
is required to help keep the vehicle on
the steered path.
You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.

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 con-
trol function).
Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle
in the following conditions:

Adjust your speed and driving to the
road conditions.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies
according to road conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
When the ABS senses that one or more
wheels are close to locking up, the
actuator rapidly applies and releases
hydraulic pressure. This action is similar
to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal
and hear a noise from under the hood or
feel a vibration from the actuator when it
is operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.
The VDC OFF switch is used to turn off the
VDC system. The VDC off 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 VDC warning
