PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000004211221

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 SR and SB section of this Service Man-

ual.

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 SR 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 har-

ness connectors.

Precautions For High-Voltage System

INFOID:0000000004211222

Refer to 

GI-24, "Precautions For High-Voltage System"

.

Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004507214

NOTE:

• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, then disconnect both 12-volt battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both 12-

volt 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 12-volt battery is disconnected or discharged, the steering wheel will lock and cannot be turned.

If turning the steering wheel is required with the 12-volt battery disconnected or discharged, follow the proce-

dure below before starting the repair operation.

OPERATION PROCEDURE

1. Connect both 12-volt battery cables.

NOTE:

Supply power using jumper cables if 12-volt battery is discharged.

2. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.

(At this time, the steering lock will be released.)

3. Disconnect both 12-volt battery cables. The steering lock will remain released with both 12-volt battery

cables disconnected and the steering wheel can be turned.

4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both 12-volt battery cables. With the brake pedal released,

turn the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steer-

ing 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 Draining Coolant

INFOID:0000000004211223

• Drain coolant when engine is cooled.

PRECAUTIONS

Precaution for Disconnecting Fuel Piping

INFOID:0000000004211224

• Before starting work, make sure no fire or spark producing items are in the work area. 

• Release fuel pressure before any removal or disassembly.

• After disconnecting pipes, plug openings to stop fuel leakage.

Precaution for Removal and Disassembly

INFOID:0000000004211225

• When instructed to use special service tools, use the specified tools. Always be careful to work safely, avoid

forceful operations. 

• Use maximum care to avoid damage to mating or sliding surfaces.

• Cover openings of engine system with tape or equivalent, if necessary, to seal out foreign materials.

• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.

• 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, follow the specifications.

Precaution for Inspection, Repair and Replacement

INFOID:0000000004211226

• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and

replace if necessary.

Precaution for Assembly and Installation

INFOID:0000000004211227

• Use torque wrench to tighten bolts or nuts.

• 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,

follow the specifications.

• Always replace the old with a new gasket, packing, oil seal or O-ring.

• Thoroughly wash, clean, and air-blow each part. Carefully check oil or 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. 

• Bleed the air trapped within the system after draining the coolant. 

• Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped).

Then make sure that there are no leaks at fuel line connections.

• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for

leakage or rattles.

Parts Requiring Angular Tightening

INFOID:0000000004211228

• Use an angle wrench for the final tightening of the following engine parts. 

- Cylinder head bolts

- Lower cylinder block bolts

- Connecting rod cap bolts

- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular

tightening)

• Do not use a torque value for final tightening. 

• The torque value for these parts are for a preliminary step.

• Ensure thread and seat surfaces are clean and coated with engine oil.

• After removing the bolts and nuts, separate the mating surface and

remove the sealant using Tool.     

CAUTION:

Be careful not to damage the mating surfaces.

• In areas where the cutter is difficult to use, use a plastic hammer to

lightly tap (1) the cutter where the RTV Silicone Sealant is applied.

Use a plastic hammer to slide the cutter (2) by tapping on the side.

CAUTION:

If for some unavoidable reason a tool such as a flat-bladed

screwdriver is used, be careful not to damage the mating sur-

faces.

LIQUID GASKET APPLICATION PROCEDURE

1. Using a scraper, remove the old Silicone RTV Sealant adhering

to the gasket application surface and the mating surface.

• Remove the sealant completely from the groove of the gasket

application surface, mounting bolts, and bolt holes.

2. Thoroughly clean the gasket application surface and the mating

surface and remove adhering moisture, grease and foreign

materials.

3. Attach the sealant tube to the tube presser.

Use Genuine Silicone RTV Sealant or equivalent. Refer to

GI-15, "Recommended Chemical Products and Sealants"

.

4. Apply the sealant using Tool without breaks to the specified

location.

• If there is a groove for the sealant application, apply the seal-

ant to the groove.

• As for the bolt holes, normally apply the sealant inside the

holes. If specified, it should be applied outside the holes. Make

sure to read the text of this manual.

• Within five minutes of the sealant application, install the mat-

ing component.

• If the sealant protrudes, wipe it off immediately.

• Do not retighten after the installation.

• After 30 minutes or more have passed from the installation, fill

the engine with the specified oil and coolant. Refer to 

MA-10,

"Fluids and Lubricants"

.

CAUTION:

Follow all specific instructions in this manual.
