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

INFOID:0000000010784294

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 AIR BAG” and
“SEAT BELT” of this Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• 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.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000010784542

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition power source and accessory

power source to the OFF, 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 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.

For vehicle with 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 operation pro-
cedure below before starting the repair operation.

OPERATION PROCEDURE

1.

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

2.

Open driver door.

3.

Turn the ignition switch to the ON position.
(At this time, the steering lock will be released.)

4.

Turn the ignition switch to OFF position with driver door open.

5.

Wait for 3 minutes or longer with driver door open.
NOTE:
• Do not close driver door because the steering wheel locks when driver door is closed.

• The auto acc function is adapted to this vehicle. For this reason, even when the ignition switch is turned

to OFF position, the accessory power source does not turned OFF and continues to be supplied for a
certain amount of time.

6.

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.

7.

Perform the necessary repair operation.

8.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the ignition switch from OFF position to ON position, then to LOCK position. (The steering wheel will lock
when the ignition switch is turned to LOCK position.)

9.

Perform self-diagnosis check of all control units using CONSULT.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000010784296

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precautions For Engine Service

INFOID:0000000010784301

DISCONNECTING FUEL PIPING

• 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.

DRAINING ENGINE COOLANT

Drain engine coolant and engine oil when the engine is cooled.

INSPECTION, REPAIR AND REPLACEMENT

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

REMOVAL AND DISASSEMBLY

• When instructed to use SST, use 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.

• Must cover openings of engine system with a tape or equivalent, 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.

ASSEMBLY AND INSTALLATION

• 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.

PRECAUTIONS

• 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. 

• After disassembling, or exposing any internal engine parts, change engine oil and replace oil filter with a new

one.

• 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.

Parts Requiring Angle Tightening

INFOID:0000000010784543

• Use the angle wrench [SST: KV10112100] for the final tightening of the following engine parts: 
- Camshaft sprocket (INT) bolt
- 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)

• 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. 

Liquid Gasket

INFOID:0000000010784544

REMOVAL OF LIQUID GASKET SEALING

• After removing mounting nuts and bolts, separate the mating sur-

face using the seal cutter [SST: KV10111100] (A) and remove old
liquid gasket sealing.

CAUTION:

Never damage the mating surfaces.

• Tap the seal cutter [SST: KV10111100] to insert it 

, and then

slide it 

 by tapping on the side as shown in the figure.

• In areas where the seal cutter [SST: KV10111100] is difficult to use,

lightly tap the parts using a plastic hammer to remove it.

CAUTION:

If for some unavoidable reason tool such as a screwdriver is
used, be careful not to damage the mating surfaces.

LIQUID GASKET APPLICATION PROCEDURE

1.

Using a scraper (A), remove old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
• Remove liquid gasket completely from the groove of the liquid

gasket application surface, mounting bolts, and bolt holes.

2.

Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
