Nissan Sentra Owners Manual: Vehicle Dynamic Control (VDC) system
The Vehicle Dynamic Control (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:
- understeer (vehicle tends to not follow
the steered path despite increased steering
input)
- oversteer (vehicle tends to spin due to
certain road or driving 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 to note the
following:
- 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.
- Adjust your speed and driving to the road
conditions.
See “Slip indicator light” and ”Vehicle Dynamic
Control (VDC) off indicator light” in the ”Instruments
and controls” section.
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 off.
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.
- Do not modify the vehicle’s suspension.
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.
- If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the VDC system may not
operate properly and the
indicator
light may illuminate.
- If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, the
indicator light
may illuminate.
- When driving on extremely inclined surfaces
such as higher banked corners,
the VDC system may not operate properly
and the indicator may
flash or
the indicator
light may illuminate.
Do not drive on these types of roads.
- When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the indicator may
flash or
the indicator
light may illuminate.
This is not a malfunction. Restart the
engine after driving onto a stable
surface.
- If wheels or tires other than the NISSAN
recommended ones are used, the VDC
system may not operate properly and
the indicator may flash
or
the indicator light may
illuminate.
- The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
