1. Insert the Genuine NISSAN Grease or equivalent, into the joint
sub-assembly serration hole until the grease begins to ooze
from the ball groove and serration hole. Refer to
USA AND CANADA : Fluids and Lubricants"
. After inserting the
grease, use a shop cloth to wipe off the grease that has oozed
out.
2. Wrap the serrated part of the drive shaft with tape. Install the
boot band and boot onto the shaft. Do not damage the boot.
NOTE:
Discard the old boot band and boot and use a new one for
assembly.
3. Remove the protective tape wound around the serrated part of
the drive shaft.
4. Attach the circlip to the drive shaft. The circlip must fit securely
into the drive shaft groove. Attach the nut to the joint sub-assem-
bly.
Use a soft hammer to press-fit the circlip.
NOTE:

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000007358878
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
Service 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:0000000007358879
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 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.
General Precaution
INFOID:0000000007358880
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the workshop.
• Be sure to work in a well ventilated area and furnish the workshop with a CO
2
fire extinguisher.
• Do not smoke while servicing the fuel system. Keep open flames and sparks away from the work
area.
CAUTION:
• Use gasoline required by the regulations for the octane rating number. Refer to
for Fuel (Unleaded Premium Gasoline Recommended)"
• Before removing fuel line parts, carry out the following procedures:
- Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
- Release fuel pressure from the fuel lines. Refer to
(VK56DE).
- Disconnect the battery negative terminal.
• Always replace O-rings and clamps with new ones.
• Do not kink or twist hoses when they are being installed.
• Do not tighten hose clamps excessively to avoid damaging hoses.
• Tighten high-pressure rubber hose clamp so that clamp end is 3 mm (0.12 in) from hose end.
• Ensure that clamp screw does not contact adjacent parts.
• After connecting the fuel tube quick connectors, make sure
the quick connectors are secure.
Ensure that the connector and resin tube do not contact any
adjacent parts.
• After installing tubes, make sure there is no fuel leakage at
connections in the following steps.
- Apply fuel pressure to fuel lines with turning ignition switch
ON (with engine stopped). Then check for fuel leaks at con-
nections.
- Start the engine and rev it up and check for fuel leaks at con-
nections.
• Use only a Genuine NISSAN fuel filler cap as a replacement. If
an incorrect fuel filler cap is used, the MIL may come on.
• For servicing “Evaporative Emission System” parts, refer to
• For checking “On Board Refueling Vapor Recovery (ORVR)”
parts, refer to
EC-489, "How to Detect Fuel Vapor Leakage"
(VQ40DE),
EC-954, "How to Detect EVAP Leakage"
