Seat Belt InspectionNHS00070
AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the col-
lision was minor and the belts show no damage and continue to operate properly. Failure to do so
could result in serious personal injury in an accident. Seat belt assemblies not in use during a colli-
sion should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioners
should be replaced even if the seat belts are not in use during a frontal collision in which the air bags
are deployed.
Replace any seat belt assembly (including anchor bolts) if:

The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).

The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide).

The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.

Anchor bolts are deformed or worn out.

The front seat belt pre-tensioner should be replaced even if the seat belts are not in use during the colli-
sion in which the air bags are deployed.
PRELIMINARY CHECK
1. Check the seat belt warning lamp/chime for proper operation as follows:
a. Turn ignition switch ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime should sound for about six seconds.
b. Fasten driver's seat belt. The seat belt warning lamp should go out and the chime (if sounding) should stop.
2. If the air bag warning lamp is blinking, perform self-diagnosis using CONSULT-II, and air bag warning lamp. Refer to SRS-20, "
SRS Operation Check" .
3. Make sure that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
4. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Ensure guide swivels freely and that webbing lays flat and does not bind in guide. Ensure height adjuster operates properly and
holds securely.
5. Check retractor operation:
a. Fully extend the seat belt webbing and check for twists, tears or other damage.
b. Allow the seat belt to retract. Ensure that webbing returns smoothly and completely into the retractor. If the seat belt does not return smoothly, wipe the inside of the loops with a clean paper cloth, because dirt
built up in the loops of the upper anchors can cause the seat belts to retract slowly.
c. Fasten the seat belt. Check the seat belt returns smoothly and completely to the retractor. If the webbing does not return smoothly, the cause may be an accumulation of dust or dirt. Use the “SEAT BELT TAPE
SET” and perform the following steps.
Inspect the front seat belt through-anchor:
1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
2. Use a clip or other device to the fix the seat belt at the center pillar webbing opening.
3. Pass a thin wire through the through-anchor webbing opening. Hold both ends of the wire and pull taut while moving it up and down several times along the webbing opening surface to remove dirt.
4. Any dirt that cannot be removed with the wire can be removed by cleaning the opening with a clean cloth.
5. Apply tape at the point where the webbing contacts the through-anchor webbing opening.

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.

SEAT BELT RETRACTOR OFF-VEHICLE INSPECTION
1. Remove the seat belt retractor assembly.
2. Slowly pull out webbing while tilting the retractor assembly forward from the mounted position without twisting the retractor assembly as shown in the figure.
If NG, replace the retractor assembly. 15 degrees or less tilt : Webbing can be pulled out.
35 degrees or more tilt : Webbing locks and cannot be pulled out.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS002UK
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.
