2000 NISSAN QUEST sensor

The supplemental air bag warning light,
displayingin the instrument panel,
monitors the circuits of the supplemental
front air bag system. The circuits monitored
by the air bag warning light include the
diagnosis sensor unit, front air bag modules
and all related wiring.
When the ignition key is in the ON or START
position, the supplemental air bag warning
light illuminates for about 7 seconds and
then turns off. This means the system is
operational.If any of the following conditions occur, the
supplemental front air bag needs servicing
and should be taken to your nearest autho-
rized NISSAN dealer.
cThe supplemental air bag warning light
remains on after approximately 7 sec-
onds.
cThe supplemental air bag warning light
flashes intermittently.
cThe supplemental air bag warning light
does not come on at all.
Under these conditions, the supplemental
front air bag may not operate properly. It
must be checked and repaired. Take your
vehicle to the nearest authorized NISSAN
dealer.
WARNING
If the supplemental air bag warning
light is on, it could mean that the
supplemental front air bag system will
not operate in an accident.
Repair and replacement procedure
The supplemental front air bag modules are
designed to inflate on a one-time-only basis.
As a reminder, unless it is damaged, the
supplemental air bag light remains illumi-
nated after inflation has occurred. Repair
and replacement of the air bag system
should be done only by an authorized NIS-
SAN dealer.
To ensure long-term functioning, the
supplemental air bag system must be
inspected 10 years after the date of
manufacture as noted on the certifica-
tion label located on the driver side front
pillar.
When maintenance work is required on the
vehicle, the supplemental front air bag sys-
tem and related parts should be pointed out
to the person conducting the maintenance.
The ignition key should always be in the
LOCK position when working under the
hood or inside the vehicle.

Shut-off delay
The length of time the headlights stay on
after the ignition is turned to OFF depends
on whether the switch is in the AUTO1 or
AUTO2 position. If the switch is in the
AUTO1 position, then the headlights stay on
for less than 1 minute after the ignition is
turned OFF. If the switch is in the AUTO2
position, the headlights stay on approxi-
mately 3 minutes after the ignition is turned
OFF.
To turn the autolamp system off, turn the
switch to the OFF,
,orposition.
Be sure you do not put anything on top
of the photo sensor located in the top left
side of the instrument panel. The photo
sensor controls the autolamp; if it is
covered, the photo sensor reacts as if it
is dark out and the headlights will illumi-
nate.
Turn signal
Move the lever up or down to signal the
turning direction. When the turn is com-
pleted, the turn signal cancels automati-
cally.
Lane change signal
To indicate a lane change, move the lever
up or down to the point where the light
begins to flash, but the lever does not latch.

The anti-lock brake system controls the
brakes at each wheel so the wheels do not
lock when braking abruptly 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 wheel
lockup, the system helps the driver maintain
steering control and helps to minimize swerv-
ing and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Normal operation
The anti-lock brake system does not operate
at speeds below 3 to 6 MPH (5 to 10 km/h).
(The speeds vary according to road condi-
tions.) When the anti-lock brake system
senses one or more wheels are close to
locking up, the actuator (under the hood)
rapidly applies and releases hydraulic pres-
sure (like pumping the brakes very quickly).
While the actuator is working, you may feel apulsation in the brake pedal and hear a noise
or vibration from the actuator under the hood.
This is normal and indicates the anti-lock
brake 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 hydraulic
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 ve-
hicle 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 com-
puter senses any malfunction, it switches
the anti-lock brake system OFF and turns
on the ABS brake warning light in the dash-
board. The brake system then operates
normally, but without anti-lock assistance.
If the light comes on during the self-test, or
while driving, take the vehicle to an authorized
NISSAN dealer for repair.
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 brake 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 four
wheels.
