When disconnecting the battery terminal, pay attention to the following.

• Always use a 12V battery as power source.

• Never disconnect battery terminal while engine is running.

• When removing the 12V battery terminal, turn OFF the ignition

switch and wait at least 30 seconds.

• For vehicles with the engine listed below, remove the battery termi-

nal after a lapse of the specified time:

NOTE:

ECU may be active for several tens of seconds after the ignition switch is turned OFF. If the battery terminal

is removed before ECU stops, then a DTC detection error or ECU data corruption may occur.

• After high-load driving, if the vehicle is equipped with the V9X engine, turn the ignition switch OFF and wait

for at least 15 minutes to remove the battery terminal.

NOTE:

• Turbocharger cooling pump may operate in a few minutes after the ignition switch is turned OFF.

• Example of high-load driving

- Driving for 30 minutes or more at 140 km/h (86 MPH) or more.

- Driving for 30 minutes or more on a steep slope.

• For vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON

the ignition switch.

NOTE:

If the ignition switch is turned ON with any one of the terminals of main battery and sub battery discon-

nected, then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:

The removal of 12V battery may cause a DTC detection error.

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

INFOID:0000000012197326

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 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, it is recommended that all maintenance

and repair be performed by an authorized NISSAN/INFINITI dealer.

• Improper repair, 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”.

Special Cautions to Ensure the Safe Disposal of Sodium-filled Exhaust Valves

INFOID:0000000012197330

Handling and disposal of sodium-filled exhaust valves requires spe-

cial care and consideration. Under conditions such as breakage with

subsequent contact with water, metal sodium which lines the inner

portion of exhaust valve will react violently, forming sodium hydrox-

ide and hydrogen which may result in an explosion. Sodium-filled

exhaust valve is identified on the top of its stem as shown in illustra-

tion.

DEALER DISPOSAL INSTRUCTIONS

CAUTION:

• Use approved shatter-resistant eye protection when performing this procedure.

• Perform this and all subsequent disposal work procedures in an open room, away from flammable

liquids. Keep a fire extinguisher, rated at least 10 ABC, in close proximity to the work area.

• Be sure to wear rubber gloves when performing the following operations.

• Make sure the resultant (high alkalinity) waste water does not contact your skin. If the waste water

does contact you, wash the contacted area immediately with large quantities of water.

• Dealers should check their respective state and local regulations concerning any chemical treatment

or waste water discharge permits which may be required to dispose of the resultant (high alkalinity)

waste water.

1. Clamp valve stem in a vice.
2. The valve has a specially-hardened surface. To cut through it,

first remove a half-round section, approximately 30 mm (1.18 in)

long using air-powered grinder until black color is removed and

silver color appears.

3. Use hacksaw to cut through approximately half the diameter of

valve stem. Make the serration at a point 40 mm (1.57 in) from

the end of valve stem.

4. Cover the serrated end of the valve with a large shop towel (A).

Strike the valve face end with a hammer, separating it into two

pieces.

5. Fill a bucket (such as a 20   oil can) with at least 10   (2-1/4

lmp gal) of water. Carefully place the alreadycut (serrated)

valves into the water one-at-a-time using a set of large tweezers

and quickly move away at least 2.7 m (9 ft).

6. The valves should be placed in a standing position as shown in

the illustration to allow complete reaction. After the bubbling

action has subsided, additional valves can be placed into the

bucket allowing each subsequent chemical reaction to subside.

However, no more than 8 valves should be placed in the same
10   (2-1/4 lmp gal) amount of water. The complete chemical

reaction may take as long as 4 to 5 hours. Remove the valves

using a set of large tweezers after the chemical reaction has

stopped. Afterwards, valves can be disposed as ordinary scrap.

Precaution for Handling High Pressure Fuel System

INFOID:0000000012197331

• High pressure fuel system components are between high pressure fuel pump and fuel injector.

• Always release fuel pressure and never start the engine when performing removal and installation.

• When removing or installing parts without releasing fuel pressure, fuel may be splashed and, if fuel contacts

skin or eyes, it may cause inflammation.

Precautions For Engine Service

INFOID:0000000012197332

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.
