locking up. Steer the vehicle to avoid obstacles.

WARNING

Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.

Self-test feature

The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and does not
indicate a malfunction. If the computer senses
a malfunction, it switches the ABS off and
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.

If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN 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.

When accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the
Vehicle Dynamic Control (VDC) system, sensors
detect these movements and control the braking
and engine output to help improve vehicle
stability.

. When the VDC system is operating, the

“SLIP” indicator in the instrument panel
blinks.

. If the “SLIP” indicator blinks, the road

conditions are slippery. Be sure to adjust
your speed and driving to these conditions.
Be sure to drive carefully. (See “Slip
indicator light” in the “2. Instruments and
controls” section, and “Vehicle Dynamic
Control (VDC) off indicator light” in the “2.
Instruments and controls” section.)

. Indicator light

If a malfunction occurs in the system, the
“SLIP” and “VDC OFF” indicator lights
illuminate in the instrument panel. As long
as these indicators are illuminated, the VDC
system function is canceled.

The VDC system uses an Active Brake Limited
Slip (ABLS) function to improve vehicle traction.
The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The
ABLS system brakes the spinning wheel, which
distributes the driving power to the other drive
