PRECAUTIONS

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

INFOID:0000000001516585

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 SR and SB section 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 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.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000001337832

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-II 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.

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-II. 

Precaution for Liquid Gasket

INFOID:0000000001337833

REMOVAL OF LIQUID GASKET SEALING

• After removing nuts and bolts, separate the mating surface, using Tool and remove old liquid gasket sealing.

CAUTION:

Be careful not to damage the mating surfaces.

• Tap Tool 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 parts, to remove it.

CAUTION:

If for some unavoidable reason suitable tool such as screw-
driver is used, be careful not to damage the mating surfaces.

LIQUID GASKET APPLICATION PROCEDURE

1.

Remove old liquid gasket adhering to the liquid gasket applica-
tion surface and the mating surface, using scraper.
• Remove liquid gasket completely from the groove of the liquid

gasket 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 Tool.

Use Genuine RTV Silicone Sealant or equivalent. Refer to 

GI-27, "Recommended Chemical Prod-

ucts and Sealants"

.

4.

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

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

holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.

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

ing component.

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

engine oil and engine coolant.

CAUTION:

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