5-24 Starting and driving
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN certified LEAF dealer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
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. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.
The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, 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 drive wheel on the same axle
that is not slipping.
. Controls brake pressure and traction motor
output to reduce drive wheel slip based on
vehicle speed (traction control function).
. Controls brake pressure at individual wheels
and traction motor output to help the driver
maintain control of the vehicle in the follow-
ing 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
warning in the instrument panel flashes. When
the warning flashes, note the following items.
. 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 according to
the road conditions.
See “Vehicle Dynamic Control (VDC) warning
light” in the “2. Instruments and controls”
section and “Vehicle Dynamic Control (VDC)
off indicator light” in the “2. Instruments and
controls” section.
If a malfunction occurs in the system, the
warning illuminates in the lower display. The
VDC system automatically turns off when this
warning light is lit.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator
illuminates
to indicate that 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
drive wheel that is not slipping. The
warning
flashes if this occurs. All other VDC functions
are off and the
warning will not flash. The
VDC System is automatically reset to ON when
