SEAT BELTS
Revision: 2006 July 2007 FX35/FX45
NOTE:
Apply the tape so that there is no looseness or wrinkling.
6. Remove the clip fixing the seat belt and ensure that the webbing returns smoothly.
7. Repeat steps above as necessary to check the other seat belts.
SEAT BELT RETRACTOR ON-VEHICLE INSPECTION
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are of the Emergency Locking Retractors (ELR) type. In an emergency (sudden stop)
the retractor will lock and prevent the webbing from extending any further. All 3-point type seat belt retractors
except the driver's seat belt also have an Automatic Locking Retractors (ALR) mode. The ALR mode (also
called child restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt
is fully extended. When the webbing is then retracted partially, the ALR mode automatically locks the seat belt
in a specific position so the webbing cannot be extended any further. To cancel the ALR mode, allow the seat
belt to fully wind back into the retractor.
Check the seat belt retractors using the following test(s) to determine if a retractor assembly is operating prop-
erly.
Stationary Inspection for ELR Function
Grasp the shoulder webbing and pull forward quickly. The retractor should lock and prevent the belt from
extending further.
Stationary Inspection for ALR Function
1. Pull out entire length of seat belt from retractor until a click is heard.
2. Retract the webbing partially. A clicking noise should be heard as the webbing retracts indicating that the retractor is in the Automatic Locking Retractor (ALR) mode.
3. Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If necessary replace the retractor assembly.
4. Allow the entire length of the webbing to retract to cancel the automatic locking mode.
Moving Inspection for ELR Function
WARNING:
Perform the following test in a safe, open area clear of other vehicles and obstructions (for example, a
large, empty parking lot). Road surface must be paved and dry. DO NOT perform the following test on
wet or gravel roads or on public streets and highways. This could result in an accident and serious
personal injury. The driver and passenger must be prepared to brace themselves in the event the
retractor does not lock.
1. Fasten driver's seat belt. Buckle a passenger into the seat for the belt that is to be tested.
2. Proceed to the designated safe area.
3. Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of a pending sudden stop. The driver and passenger must be prepared to brace themselves in the event the retractor does not lock.
Apply brakes firmly and make a very hard stop.
During stop, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock, per-
form the retractor off-vehicle inspection.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NHS00073
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 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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceNHS00074

Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.

Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.

Diagnosis sensor unit must always be installed with their arrow marks “ ⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before instal-
lation and replace as required.

The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steer-
ing wheel and column after removal of steering gear.

Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and seat mounted front side air bag module standing with the stud bolt side facing
down.

Conduct self-diagnosis to check entire SRS for proper function after replacing any components.

After air bag inflates, the front instrument panel assembly should be replaced if damaged.

Always replace instrument panel pad following front passenger air bag deployment.

Disposal, recycling, and transportation of air bag modules and seat belt pre-tensioners should be per-
formed in compliance with applicable federal, state and local laws and regulations.
Occupant Classification System PrecautionNHS0009N
Replace occupant classification system control unit and passenger front seat cushion as an assembly.

REMOVAL
Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:

Be careful not to scratch the road wheel during removal.

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight
with a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight.

Before installing the balance weight, be sure to clean the mating surface of the road wheel.
a. Indicated unbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz)
37.5 g (1.32 oz) bal-
ance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
36.2
35 g (1.23 oz)
36.3
37.5 g (1.32 oz)
b. Install balance weight in the position shown in the figure.
c. When installing balance weight to road wheels, set it into the grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the tire
balance machine indication position (angle).
CAUTION:

Always use genuine NISSAN adhesion balance weights.

Balance weights are non-reusable; always replace with
new ones.

Do not install more than three sheets of balance weight.
