ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
The Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent ac-
cidents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. 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. Ulti-
mately, the driver is responsible for safety.
Tire type and condition may also affect brak-
ing effectiveness.
— When replacing tires, install the speci-
fied 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 Infor-
mation label. See “Tire and Loading In-
formation 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) con-
trols 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 pre-
venting each wheel from locking, the sys-
tem 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 ve-
hicle 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, elec-
tric pumps, hydraulic solenoids and a
computer. The computer has a built-in di-
agnostic 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 malfunc-
tion. If the computer senses a malfunc-
tion, it switches the ABS off and illumi-
nates the ABS warning light on the instru-
ment panel. The brake system then
operates normally, but without anti-lock
assistance. If the ABS warning light illu-
minates during the self-test or while driv-
ing, have the vehicle checked by an
INFINITI dealer.
