ANTI-LOCK BRAKING SYSTEM
(ABS)

WARNING

The ABS is a sophisticated device, but it

cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping 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 ve-
hicle 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 Tire and Loading
Information label. For additional in-
formation, refer to the “Technical and
consumer information” section of
this manual.

– For additional information, refer to

“Wheels and tires” in the “Mainte-
nance 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 pre-
vent 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 slip-
pery surfaces.

Using the system

Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate 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 malfunc-
tion, 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.
