DescriptionEAS001GG
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EAS001GH
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo 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 must be per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo 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 harnesses or
harness connectors.
Precautions for NATS (NISSAN ANTI-THEFT SYSTEM)EAS001GI
NATS 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.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.
lWhen NATS detects trouble, the security indicator lamp lights up while ignition switch is in "ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.
lWhen servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), CONSULT-II hardware and CONSULT-II NATS software is necessary.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-
II operation manual, NATS.
Therefore, CONSULT-II NATS software (program card and operation manual) must be kept strictly con-
fidential to maintain the integrity of the anti-theft function.
lWhen servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), it may be necessary to re-register original key identification. Therefore, be sure to
receive all keys from vehicle owner. A maximum of four or five key IDs can be registered into NATS.
lWhen failing to start the engine first time using the key of NATS, start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectEAS001HY
NOTE:
lThis Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).
lRemove and install all control units after disconnecting both battery cables with the ignition knob in the
²LOCK²position.
lAlways use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.

PRECAUTIONS
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
DIESEL ENGINE
Diesel fuel of at least 50 cetane.
If two types of diesel fuel are available, use summer or winter fuel properly according to the following temper-
ature conditions.
lAbove –7°C(20°F) ... Summer type diesel fuel.
lBelow –7°C(20°F) ... Winter type diesel fuel.
CAUTION:
lDo not use home heating oil, gasoline or other alternate fuels in your diesel engine. The use of
those can cause engine damage.
lDo not use summer fuel at temperatures below –7°C(20°F). The cold temperatures will cause wax
to form in the fuel. As a result, it may prevent the engine from running smoothly.
lDo not add gasoline or other alternate fuels to diesel fuel.
Precautions for Multiport Fuel Injection System or Engine Control SystemEAS001GN
lBefore 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.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Turbocharger (If Equipped)EAS001GO
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean sup-
ply of oil flowing through the turbocharger and to follow all required
maintenance instructions and operating procedures.
lAlways use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
lAvoid accelerating engine to a high rpm immediately after start-
ing.
lIf engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting if off.
Precautions for HosesEAS001GP
HOSE REMOVAL AND INSTALLATION
lTo prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.

lDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
lBefore servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
lThe air bag diagnosis sensor unit must always be installed with the arrow marks “Ü” pointing toward the
front of the vehicle for proper operation. Also check the air bag diagnosis sensor unit for cracks, deformi-
ties or rust before installation and replace as required.
lThe spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
lHandle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and seat mounted front side air bag module standing with the stud bolt side facing
down.

lWhen checking the headlamp on/off operation, check it on vehicle and with the power connected to the
vehicle-side connector.
lDo not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
lWhen the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
lLeaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor-
mance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when
replacing the bulb.
lDo not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.
