COMPONENTS OF THE
SUPPLEMENTAL RESTRAINT
SYSTEM1. Crash zone sensor
2. Supplemental front air bag modules
3. Supplemental curtain side-impact air bag
modules (if so equipped for Coupe models)
4. Diagnosis sensor unit
5. Satellite sensors
6. Seat belt pre-tensioner retractor
7. Supplemental side air bag modules (if so
equipped)
Supplemental front air bag systemThe driver supplemental air bag is located in the
center of the steering wheel; the front passenger
supplemental air bag is mounted in the instru-
ment panel. These systems are designed to
meet optional certification requirements under
U.S. regulations. They are also permitted in
Canada. The optional certification allows front air
bags to be designed to inflate somewhat less
forcefully than previously.However, all of the
information, cautions and warnings in this
manual still apply and must be followed.
The front air bags are designed to inflate in
higher severity frontal collisions, although theymay inflate if the forces in another type of
collision are similar to those of a higher severity
frontal impact. They may not inflate in certain
frontal collisions. Vehicle damage (or lack of it) is
not always an indication of proper supplemental
air bag operation.
The supplemental air bag system has dual stage
inflators for both the driver and passenger air
bags. The system monitors information from the
crash zone sensor, the diagnosis sensor unit and
seat belt buckle sensors that detect if the seat
belts are fastened, inflator operation is based on
the severity of a collision and whether the seat
belts are being used. Only one front air bag may
inflate in a crash, depending on the crash sever-
ity and whether the front occupants are belted or
unbelted. This does not indicate improper per-
formance of the system. If you have any ques-
tions about the performance of your air bag
system, contact a NISSAN dealer.
When the supplemental front air bag inflates, a
fairly loud noise may be heard, followed by
release of smoke. This smoke is not harmful and
does not indicate a fire. Care should be taken
not to inhale it, as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
Supplemental front air bags, along with the use
of seat belts, help to cushion the impact force on

The exhaust system and body should
be inspected by a qualified mechanic
whenever:
•The vehicle is raised for service.
•You suspect that exhaust fumes
are entering into the passenger
compartment.
•You notice a change in the sound
of the exhaust system.
•You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.THREE WAY CATALYSTThe three way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the converter are burned at high tem-
peratures to help reduce pollutants.
WARNING

The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-mals or flammable materials away
from the exhaust system compo-
nents.

Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION

Do not use leaded gasoline. Deposits
from leaded gasoline will seriously
reduce the three-way catalyst’s abil-
ity to help reduce exhaust pollutants.

Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by a NISSAN
dealer.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.

Do not race the engine while warm-
ing it up.

Do not push or tow your vehicle to
start the engine.
LOW TIRE PRESSURE WARNING
SYSTEMThis vehicle is equipped with the low tire pres-
sure warning system. It monitors tire pressure of
all tires except the spare. When the low tire
pressure warning light is lit, one or more of your
tires is significantly under-inflated. The system
also displays pressure of all tires (except the
spare tire) on the trip computer by sending a
signal from a sensor that is installed in each
wheel.
The low tire pressure warning system will acti-
vate only when the vehicle is driven at speeds
above 20 MPH (32 km/h). This system may not
detect a sudden drop in tire pressure (for ex-
ample, a flat tire by catching something while
driving).
Starting and driving

Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and the
outside temperature. Low outside temperature
can lower the temperature of the air inside the
tire which can cause a lower tire inflation pres-
sure. This may cause the low tire pressure
warning light to illuminate.
If the warning light illuminates in low ambient
temperatures as described above, check the tire
pressure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure shown
on the Tire and Loading Information label to turn
the low tire pressure warning light OFF.
Frequently check the tire pressure indicator on
the trip computer and adjust pressure of each
tire properly. See “Trip computer” in the “2.
Instruments and controls” section for the tire
pressure indicator.Low tire pressure warningIf the vehicle is being driven with low tire pres-
sure*, the low tire pressure warning light comes
on, and the chime sounds for about 10 seconds.
On the trip computer, the PSI indicator starts
flashing and the current display switches to the
tire pressure indicator.
*: lower than 26 psi (for 225/50R17 and
235/50R17 tires on
Roadster model)lower than 28 psi (except for the above)
For additional information regarding the above
warning, see “Trip computer” and
“Warning/indicator lights and audible remind-
ers” in the “2. Instruments and controls” section.
WARNING

If the low tire pressure warning light
in the meter panel comes on and/or
the PSI indicator on the trip computer
flashes while driving, avoid sudden
steering maneuvers or abrupt brak-
ing, reduce vehicle speed, pull off the
road to a safe location and stop the
vehicle as soon as possible. Serious
vehicle damage could occur and may
lead to an accident and could result
in serious personal injury. Check the
tire pressure for all four tires. Adjust
the tire pressure to the recom-
mended COLD tire pressure shown
on the Tire and Loading Information
label to turn the low tire pressure
warning light OFF. If you have a flat
tire, replace it with a spare tire as
soon as possible. (See “Flat tire” inthe “6. In case of emergency” section
for changing a flat tire.)

When a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact a NISSAN dealer as
soon as possible for tire replacement
and/or system resetting.

Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CAUTION
Do not place metalized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the
signals from the tire pressure sensors,
and the low tire pressure warning sys-
tem will not function properly.

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 featureThe anti-lock brake system consists of electronic
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
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 mal-
function, it switches the anti-lock brake system
OFF and turns on the ABS warning light in the
dashboard. The brake system will then behave
normally, but without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to a NISSAN dealer for repair at your
earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces but remember that
the stopping distance on slippery sur-
faces 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 distance 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.

When replacing tires, install the
specified size of tires to the front and
rear.

When installing a spare tire, make
sure it is the proper size and type asspecified on the Tire and Loading
Information label. See “Vehicle iden-
tification” in the “9. Technical and
consumer information” section for
the Tire and Loading Information la-
bel location.
