Nissan Micra: Vehicle Dynamic Control (VDC) system
Nissan Micra Owners Manual
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 so 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.
For additional information, refer to “Vehicle Dynamic
Control (VDC) OFF switch” in the ”Instruments
and controls” section of this manual.
If a malfunction occurs in the system, the
and indicator lights come 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.
- 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 both the and
indicator
lights 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 both the
and the indicator
lights may
illuminate.
- If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, both the
and
indicator lights 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
both the and
indicator
lights 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
both the and
indicator
lights 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 both
the and
indicator lights may
illuminate.
- The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.

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
- 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 both the and
indicator
lights 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 both the
and the indicator lights
may
illuminate.
- If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, both the
and
indicator lights 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
both the and
indicator
lights 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
both the and
indicator
lights 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 both
the and
indicator lights may
illuminate.
- The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
