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 that the anti-lock
system is working properly. However, the
pulsation may indicate that 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 ABS 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 may also affect
braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all 4 wheels.

When installing a spare tire, make sure
it is the proper size and type as speci-
fied on the tire placard. For tire placard
location information, refer to ``Tire
placard'' in the Owner's Manual index.Refer to ``Wheels and tires'' in the ``Do-
