Discard the old boot bands and use new ones for assembly.
10. After installing the sliding joint housing to the drive shaft, rotate the boot to check that the boot is posi-
tioned correctly. If the boot is not positioned correctly , reposition the boot and secure the boot using a new
boot band.
Wheel Side
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 MA-13, "
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.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005390742
The Supplemental Restraint System such as “A IR 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 w hether 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 inopera tive, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses 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 electri c 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 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005390743
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 pow er 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.

FUEL TANK
REMOVAL
WARNING:
Follow the “General Precautions” before working on the fuel system. Refer to FL-4, "
General Precau-
tion".
1. Drain the fuel from the fuel tank, if necessary. • Position the vehicle so it is level.
2. Remove the fuel filler cap to release the pressure from inside the fuel tank.
3. Check the fuel level on level gauge. If the fuel gauge indicates more than the level as shown (full or almost full), drain the fuel
from the fuel tank until the fuel gauge indicates the level as
shown, or less.
• If the fuel pump does not operate, use the following procedureto drain the fuel to the specified level after disconnecting the
fuel filler hose from the fuel filler pipe.
a. Insert a suitable hose of less than 15 mm (0.59 in) diameter into the fuel filler pipe through the fuel filler opening to drain the fuel
from fuel filler pipe.
b. Insert a suitable hose into the fuel tank through the fuel filler hose to drain the fuel from the fuel tank.
• As a guide, the fuel level reaches the fuel gauge position as shown, or less, when approximately 14
liters (3 3/4 US gal, 3 1/8 Imp gal) of fuel are drained from the fuel tank.
4. Remove the LH rear wheel and tire. Refer to WT-49, "
Rotation" .
5. Disconnect the fuel filler hose from the fuel filler pipe and dis- connect the vent hose quick connector.
6. Release the fuel pressure from the fuel lines. Refer to EC-489, "
Fuel Pressure Check" .
7. Disconnect the battery negative terminal. Refer to PG-74, "
Removal and Installation".
8. Remove the second row seat and the third row LH seat. Refer to SE-56, "
Removal and Installation" (sec-
ond row), SE-59, "
LH Side Seat" (third row).
9. Remove the second and third row rear seat belt buckles mounted on the floor. Refer to SB-7, "
Removal
and Installation of Second Row Seat Belt", SB-8, "Removal and Installation of Third Row Seat Belt".
10. Remove the LH center pillar trim, the LH rear trim panel, and the LH rear side door kick plate and weather
stripping. Refer to INT-14, "
Removal and Installation" .
11. Remove the second row rear center console and base (If equipped). Refer to IP-21, "
Removal and Instal-
lation" .
12. Reposition the floor carpet out of the way to access the inspection hole cover, located under the center LH
rear seat.
