PrecautionsNJGI0001Observe the following precautions to ensure safe and proper
servicing. These precautions are not described in each indi-
vidual section.
SGI646
PRECAUTIONS FOR SUPPLEMENTAL RESTRAINT
SYSTEM (SRS) “AIR BAG” AND “SEAT BELT
PRE-TENSIONER”
NJGI0001S01The Supplemental Restraint System such as “AIR BAG” and “SEAT
BELT PRE-TENSIONER” used along with a seat belt, helps to
reduce the risk or severity of injury to the driver and front passen-
ger for certain types of collision. The SRS system composition
which is available to NISSAN MODEL N16 is as follows (The com-
position varies according to the destination and optional equip-
ment.):
For a frontal collision
The Supplemental Restraint System consists of driver air bag
module (located in the center of the steering wheel), front pas-
senger air bag module (located on the instrument panel on
passenger side), front seat belt pre-tensioners, a diagnoses
sensor unit, warning lamp, wiring harness and spiral cable.
For a side collision
The Supplemental Restraint System consists of front side air
bag module (located in the outer side of front seat), side air bag
(satellite) sensor, diagnoses sensor unit (one of components of
air bags for a frontal collision), wiring harness, warning lamp
(one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in
theRS sectionof this Service Manual.
WARNING:
To avoid rendering the SRS inoperative, which could
increase the risk of personal injury or death in the event
of a collision which would result in air bag inflation, all
maintenance should be performed by an authorized
NISSAN dealer.
Improper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury caused
by unintentional activation of the system. For removal of
Spiral Cable and Air Bag Module, see the RS section.
Do not use electrical test equipment on any circuit related
to the SRS unless instructed to in this Service Manual.
SRS wiring harnesses can be identified by yellow and/or
orange harness connector.
PRECAUTIONS FOR NATS (NISSAN ANTI-THEFT
SYSTEM)
NJGI0001S02NATS will immobilize the engine if someone tries to start it without
the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS
registered.

PRECAUTIONS
Precautions
GI-3

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically. Continued refueling may cause fuel
overflow, resulting in fuel spray and possibly a fire.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do
not carelessly disconnect the harness connectors which are
related to the engine control system and TCM (Transmission
Control Module) system. The connectors should be discon-
nected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
SGI787
PRECAUTIONS FOR MULTIPORT FUEL INJECTION
SYSTEM OR ENGINE CONTROL SYSTEM
NJGI0001S04Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
Be careful not to jar components such as ECM and mass air
flow sensor.
PRECAUTIONS FOR THREE WAY CATALYSTNJGI0001S05If a large amount of unburned fuel flows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
Use unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
When checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
Do not run engine when the fuel tank level is low, otherwise the
engine may misfire, causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable
material off the exhaust pipe and the three way catalyst.
SMA019D
PRECAUTIONS FOR HOSESNJGI0001S06Hose Removal and InstallationNJGI0001S0601To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.
