Supplemental front air bag system
The driver supplemental front air bag is lo-
cated in the center of the steering wheel. The
passenger supplemental front 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
the front air bags to be designed to inflate
somewhat less forcefully than previously.
However, all of the information, cautionsand warnings in this manual still apply
and must be followed.
The supplemental front air bag system is
designed 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 front
air bag system operation.
When the supplemental front air bag in-
flates, a fairly loud noise may be heard,
followed by the release of smoke. Thissmoke is not harmful and does not indicate
a fire, but care should be taken to not
intentionally inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.
The supplemental front 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 serious injuries. However, an inflat-
ing supplemental front air bag may cause
facial abrasions or other injuries. Supple-
mental front 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
front air bags inflate quickly in order to help
protect the front occupants, the force of the
supplemental front air bag inflating can in-
crease the risk of injury if the occupant is too
close to or is against the supplemental front
air bag module during inflation.
The supplemental front air bags deflate
quickly after a collision.

The supplemental front air bags operate
only when the ignition switch is in the
ON or START position.
After turning the ignition key to the ON
position, the supplemental air bag warn-
ing light illuminates. The supplemental
air bag warning light will turn off after
about 7 seconds if the system is opera-
tional.
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 front air bag inflates.
cRight after inflation, several supple-
mental front air bag system compo-
nents 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 front air bag sys-
tem. This is to prevent accidental in-
flation of the supplemental front air
bags or damage to the supplemental
front 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 front
air bag system.
c
Tampering with the supplemental front
air bag system may result in serious
personal 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 front air bag system.cWork around and on the supplemental
front air bag system should be done by
an authorized NISSAN dealer. Installa-
tion of electrical equipment should
also be done by an authorized NISSAN
dealer. The yellow SRS wiring should
not be modified or disconnected. Un-
authorized electrical test equipment
and probing devices should not be
used on the supplemental front 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 front air bag system and guide the
buyer to the appropriate sections in this
owner's manual.

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.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As a
result, your braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
ANTI-LOCK BRAKE SYSTEM
(ABS) (if so equipped)
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 roadconditions. 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.
