dashboard NISSAN ALTIMA 1999 L30 / 2.G Owners Manual

The driver supplemental air bag is located in
the center of the steering wheel. The front
passenger supplemental air bag is mounted in
the dashboard above the glove box.
These systems are designed to meet op-
tional certification requirements under U.S.
regulations. They are also permitted in
Canada. The optional certification allows air
bags to be designed to inflate somewhat
less forcefully than previously.However, all
of the information, cautions and warn-
ings in this manual still apply and must
be followed.
The supplemental air bag system is de-signed to inflate in higher severity frontal
collisions, although it may inflate if the
forces in another type of collision are similar
to those of a higher severity frontal impact. It
may not inflate in certain frontal collisions.
Vehicle damage (or lack of it) is not always
an indication of proper supplemental air bag
system operation.
When the supplemental air bag inflates, a
fairly loud noise may be heard, followed by
the release of smoke. This smoke is not
harmful and does not indicate a fire, but
care should be taken not to unintentionally
inhale it, as it may cause irritation andchoking. Those with a history of breathing
trouble should get fresh air promptly.
The supplemental air bags, along with the
use of seat belts, help to cushion the impact
force on the face and chest of the occupant.
They can help save lives and reduce seri-
ous injuries. However, an inflating supple-
mental air bag may cause facial abrasions
or other injuries. Supplemental air bags do
not provide restraint to the lower body.
Seat belts should be correctly worn and the
driver and passenger seated upright as far
as practical away from the steering wheel or
instrument panel. Since the supplemental air
bags inflate quickly in order to help protect
the front occupants, the force of the supple-
mental air bag inflating can increase the risk
of injury if the occupant is too close to or is
against the supplemental air bag module
during inflation.
The supplemental air bags deflate quickly
after a collision.
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.

WARNING
c
Do not place any objects on the steer-
ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the supple-
mental air bag inflates.
cRight after inflation, several supple-
mental air bag system components
will be hot. Do not touch them; you
may severely burn yourself.
c
No unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This
is to prevent accidental inflation of
the supplemental air bag or damage
to the supplemental air bag system.
cDo not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the supplemental air
bag system.c
Tampering with the supplemental air
bag system may result in serious per-
sonal injury. Tampering includes
changes to the steering wheel and the
instrument panel assembly by placing
material over the steering wheel pad
and above the dashboard, or by install-
ing additional trim material around the
supplemental air bag system.
cWork around and on the supplemen-
tal air bag system should be done by
an authorized NISSAN dealer. Instal-
lation of electrical equipment should
also be done by an authorized NIS-
SAN dealer. The yellow SRS wiring
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the supple-
mental air bag system.
cThe SRS wiring harnesses are cov-
ered with yellow insulation either
just before the harness connectors
or over the complete harness for
easy identification.When selling your vehicle, we request that
you inform the buyer about the supple-
mental air bag system and guide the buyer
to the appropriate sections in this owner's
manual.

increases wear on the brake linings and
pads, and reduces gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.
WARNING
c
While driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
cIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.The anti-lock brake system installed in
some models controls the brakes at each
wheel so the wheels do not lock when
braking abruptly or when braking on slip-
pery surfaces. The system detects the rota-
tion 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 mini-
mize swerving 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 oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h). The speeds vary according to road
conditions. When the anti-lock system
senses that 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
a pulsation in the brake pedal and hear a
noise or vibration 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 is sophisticated,
with electronic sensors, electric pumps, and
hydraulic solenoids controlled by a com-
puter. The computer has a built-in diagnos-
tic 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 indica-
tion 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.
