1998 NISSAN QUEST sensor

Warning labels about the supplemental air
bag system are placed in the vehicle.The supplemental air bag warning light,
displaying AIR BAG in the instrument panel,
monitors the circuits of the supplemental air
bag. The circuits monitored by the supple-
mental air bag light include the diagnosis
sensor unit, supplemental 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.

The autolamp system allows the headlights
to be set so they turn on and off automati-
cally. The autolamp system can turn on the
headlights automatically when it is dark,
turn off the headlights when it is light, and
keep the headlights on for up to three
minutes after you turn the key to OFF.
To set the autolamp system:
1. Make sure the headlight switch is in the
OFF position. If the headlight switch is in
the
orposition, the autolamp
system is canceled.
2. Turn the ignition key to ON.3. Use the autolamp switch to activate the
autolamp feature. It is to the left of the
steering wheel.
4. Turn the switch to the right. A slight
detent in the switch indicates it has been
turned past the off position. After the
switch is turned past the detent, the
autolamp automatically turns the lamps
on and off.
Shut-off delay
The length of time the autolamps stay on
after the ignition is turned to OFF depends
on how far the switch is turned to the right.
If the switch is turned all the way to the right,
the headlights stay on about three minutes
after the ignition is turned to OFF. If the
switch is turned only a little way to the right,
the headlights may stay on for less than a
minute.
To turn the autolamp system off, turn the
switch all the way to the left until the detent
is felt.Be sure you do not put anything on top
of the photo sensor located in the top
right 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
illuminate.

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 system senses one
or more wheels are close to locking up, the
actuator (under the hood) rapidly applies and
releases hydraulic pressure (like pumping the
brakes very quickly). While the actuator isworking, you may feel a pulsation in the brake
pedal and hear a noise or vibration from the
actuator under the hood. This is normal and
indicates the anti-lock system is working prop-
erly. 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 com-
puter 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-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 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.
