PRECAUTIONSPFP:00001
DescriptionEAS000FN
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”
EAS000P8
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:
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 must be per-
formed by an authorized NISSAN/INFINITI dealer.
Improper 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.
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 harnesses or
harness connectors.
Precautions for NATS (NISSAN ANTI-THEFT SYSTEM)EAS000FP
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.
When 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.
When 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.
When 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.
When 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.

TIMING CHAIN
14. Set No. 1 cylinder at TDC on its compression stroke with the following procedure:
a. Rotate crankshaft pulley clockwise and align TDC mark to timing
indicator on front cover.
b. At the same time, make sure that the mating marks on camshaft
sprockets are located as shown in the figure.
If not, rotate crankshaft pulley one more turn to align mating
marks to the positions in the figure.
15. Remove crankshaft pulley with the following procedure:
a. Fix crankshaft pulley with a pulley holder (commercial service
tool), loosen crankshaft pulley bolt, and locate bolt seating sur-
face at 10 mm (0.39 in) from its original position.
b. Attach a pulley puller (special service tool) in the M 6 thread hole
on crankshaft pulley, and remove crankshaft pulley.
16. Remove front cover with the following procedure:

b. Set the dial indicator at the location as shown in the figure. Turn-
ing crankshaft gradually, set the indicator scale to “0” where the
piston protrusion is maximized.
c. Move the dial indicator stand so that the tip of dial indicator can
contact cylinder block. Read the difference.
d. Measure two points from each cylinder in order to obtain each
mean value of them. Choose a properly thick gasket corre-
sponding the highest number of the four values.
*: Measured with head bolts tightened
2. Apply a continuous bead of liquid gasket with the tube presser
(special service tool: WS39930000) as shown in the figure.
3. Install cylinder head assembly.
a. Apply engine oil to bolt threads and seat surfaces.
b. Tighten all bolts in numerical order as shown.
