PRECAUTIONS

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

INFOID:0000000006635750

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

Instruction. 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 Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion 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:0000000006247843

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

LOCK

 position.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-

anism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and

steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, 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. Use the Intelligent Key or mechanical key to turn the ignition switch to the 

ACC

 position. At this time, the

steering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be

rotated.

4. Perform the necessary repair operation.

PRECAUTIONS

5. When the repair work is completed, return the ignition switch to the 

LOCK

 position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

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

Precaution for Liquid Gasket

INFOID:0000000006247844

REMOVAL OF LIQUID GASKET SEALANT

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

remove old liquid gasket sealant using Tool.

CAUTION:

Be careful not to damage the mating surfaces.

• Tap seal cutter to insert it (1), and then slide it by tapping on the

side (2) as shown.

• In areas where Tool is difficult to use, use plastic hammer to lightly

tap the part, to remove it.

CAUTION:

If for some unavoidable reason tool such as screwdriver is

used, be careful not to damage the mating surfaces.

LIQUID GASKET APPLICATION PROCEDURE

1. Remove the old liquid gasket adhering to the gasket application

surface and the mating surface using suitable tool.

• Remove liquid gasket completely from the groove of the gas-

ket application surface, bolts, and bolt holes.

2. Thoroughly clean the mating surfaces and remove adhering

moisture, grease and foreign materials.

3. Attach liquid gasket tube to the Tool.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-14, "Recommended Chemical Products and Sealants"

.

4. Apply the liquid gasket without breaks to the specified location

with the specified dimensions.

• If there is a groove for the liquid gasket application, apply the

liquid gasket to the groove.

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

holes. Occasionally, it should be applied outside the holes.

Make sure to read the text of this instruction.

• Within five minutes of liquid gasket application, install the mat-

ing component.

• If the liquid gasket protrudes, wipe it off immediately.

• Do not retighten nuts or bolts after the installation.

• Wait 30 minutes or more after installation, before refilling the

engine with engine oil and engine coolant.

CAUTION:

If there are specific instructions in this instruction, observe them.
