ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
. The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery surfaces
will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
.
roads, or if you are using tire chains.
Always maintain a safe distance
from the vehicle in front of you.
Ultimately, the driver is responsible
for safety.
Tire type and condition may also
affect braking effectiveness.
— When replacing tires, install the
specified size of tires on all four
wheels.
— When installing a spare tire,
make sure that it is the proper
size and type as specified on the
5-26 Starting and driving
Tire and Loading Information
label. See “TIRE AND LOADING
INFORMATION LABEL” in the “9.
Technical and consumer information”
section of this manual.
— For detailed information, see
“WHEELS AND TIRES” in the
“8. Maintenance and do-it-yourself”
section of this manual.
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping distances.
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 operates
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
