PRECAUTIONS

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

INFOID:0000000006492600

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:

• 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 the “SRS AIR BAG”.

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

WARNING:

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, DO NOT 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:0000000006492601

NOTE:
• Before removing and installing any control units, first turn the ignition switch to the LOCK position, then dis-

connect 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.

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.

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

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.

CO-56

< PRECAUTION >

[K9K]

PRECAUTIONS

5.

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

6.

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

Precaution for Liquid Gasket

INFOID:0000000006492602

REMOVAL OF LIQUID GASKET

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

surface using a seal cutter and remove the liquid gasket.

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 the gasket applied area.

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 liquid gasket adhering to the
gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the

gasket application surface, mounting bolts and bolt holes.

2.

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

3.

Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.

4.

Apply the gasket without breaks to the specified location with the
specified dimensions.
• If there is a groove for the liquid gasket application, apply the

gasket to the groove.

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

holes. If specified, it should be applied outside the holes. Make
sure to read the instruction in this manual.

• Within five minutes of gasket application, install the mating

component.

• If the liquid gasket protrudes, wipe it off immediately.
• Do not retighten after the installation.
• After 30 minutes or more have passed from the installation, fill

the engine oil and coolant.

CAUTION:

If there are instructions in this manual, observe them.

Check radiator for mud or clogging. If necessary, clean radiator as follows.

CAUTION:

• Be careful not to bend or damage the radiator fins.
• When radiator is cleaned without removal, remove all surrounding parts such as radiator fan, radia-

tor shroud and horns. Then tape the harness and connectors to prevent water from entering.

1.

Apply water by hose to the back side of the radiator core vertically downwards.

2.

Apply water again to all radiator core surface once per minute.

3.

Stop washing if any stains no longer flow out from the radiator.

4.

Blow air into the back side of radiator core vertically downwards.

• Use compressed air lower than 490 kPa (4.9 bar 5 kg/cm

2

, 71psi) and keep distance more than 30 cm (11.8

in). 

5.

 Blow air again into all the radiator core surface once per minute until no water sprays out.
