tuator is working, you may feel a pulsation in
the brake pedal and hear a noise or vibra-
tion from the actuator under the hood. This
is normal and indicates the anti-lock system
is working properly. However, the pulsation
may indicate road conditions are hazardous
and extra care is required while driving.
Self-test feature
The anti-lock brake system consists of elec-
tronic sensors, electric pumps, and hydrau-
lic solenoids controlled by 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 is not an indication of any
malfunction. If the computer senses any
malfunction, it switches the anti-lock brake
system OFF and turns on the ANTI-LOCK
brake warning light in the dashboard. The
brake system then operates normally, but
without anti-lock assistance.
If the light comes on during the self check,
or while driving, take your vehicle to your
NISSAN dealer for repair at your earliest
convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent
accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces, but re-
member that the stopping distance on
slippery surfaces will be longer than on
normal surfaces, even with the anti-
lock system. Stopping distances may
also be longer on rough, gravel or
snow covered roads, or if you are using
tire chains. Always maintain a safe dis-
tance from the vehicle in front of you.
Ultimately, the responsibility for safety
of self and others rests in the hands of
the driver.
Tire type and condition of tires may
also affect braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all 4 wheels.cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
``Tire placard'' in the Owner's
Manual index.
