Precaution for Procedure without Cowl Top CoverINFOID:0000000003802312
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003802225
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIRBAG” and “SEAT BELT” 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 performed by
an authorized NISSAN/INFINITI 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 “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003802313
NOTE:
 Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
PIIB3706J

< PRECAUTION >
PRECAUTIONS
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
Precaution for Drain Engine Coolant and Engine OilINFOID:0000000003802227
Drain engine coolant and engine oil when the engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000003802228
 Before starting work, check no fire or spark producing items are in the work area.
 Release fuel pressure before disconnecting and disassembly.
 After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000003802229
 When instructed to use SST, use the specified tools. Always be careful to work safely, avoid forceful or unin-
structed operations.
 Exercise maximum care to avoid damage to mating or sliding surfaces.
 Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
check that dowel pins are installed in the original position.
 Cover openings of engine system with a tape or the equivalent, if necessary, to seal out foreign materials.
 Mark and arrange disassembly parts in an organized way for easy troubleshooting and reassembly.
 When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be used
in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000003802230
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000003802231
 Use torque wrench to tighten bolts or nuts to specification.
 When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
 Replace with new gasket, packing, oil seal or O-ring.
 Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
check that dowel pins are installed in the original position.
 Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
 Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
 Release air within route when refilling after draining engine coolant.
 After repairing, start the engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.
Precaution for Angle TighteningINFOID:0000000003802232
 Use the angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
- Cylinder head bolts
- Main bearing cap bolts
- Connecting rod cap bolts
- Crankshaft pulley bolt (No the angle wrench is required as bolt flange is provided with notches for angle
tightening)
 Never use a torque value for final tightening.
 The torque value for these parts are for a preliminary step.

3. Hold the hexagonal part in center of drive belt auto-tensioner
pulley with a box wrench securely. Then move the wrench han-
dle in the direction of arrow (loosening direction of drive belt).
CAUTION:
 Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.
 Never loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Never turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pulley.
4. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole (A) of the retaining boss to
fix drive belt auto-tensioner pulley.
 Keep drive belt auto-tensioner pulley arm locked after drive belt is removed.
5. Loosen drive belt from water pump pulley in sequence, and remove it.
INSTALLATION
1. Hook drive belt on to all pulleys except for drive belt auto-tensioner pulley, and then onto drive belt auto-
tensioner pulley finally.
CAUTION:
 Confirm drive belt is completely set to pulleys.
 Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
2. Release drive belt auto-tensioner, and apply tension to drive belt.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm tension of drive belt at indicator is within the possible use range. Refer to EM-12, "
Exploded
View".

INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
In cases of removing/installing or replacing camshaft and valve-
related parts, or of unusual engine conditions due to changes in
valve clearance (found malfunctions during stating, idling or causing
noise), perform inspection as follows:
1. Remove rocker covers (bank 1 and bank 2). Refer to EM-49, "
Exploded View".
2. Measure the valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke.
 Rotate crankshaft pulley clockwise to align timing mark
(grooved line without color) ( ) with timing indicator.
 Check that intake and exhaust cam nose on No. 1 cylinder
(engine front side of bank 1) are located as shown in the fig-
ure.
 If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.
b. Use a feeler gauge, measure the clearance between valve lifter
and camshaft.
