< REMOVAL AND INSTALLATION >

FRONT SEAT BELT

Replace any seat belt assembly (including anchor bolts) if:
• The seat belt is in use at the time of a collision (except for minor collisions and the belts, retractors and buck-

les show no damage and continue to operate properly).

• The seat belt is damaged in an accident (i.e. torn webbing, bent retractor or guide, etc.).
• The seat belt attaching point is damaged in an accident. Inspect the seat belt attaching area for damage or

distortion and repair if necessary before installing a new seat belt assembly.

• Anchor bolts are deformed or worn out.
• The seat belt pre-tensioners must be replaced even if the seat belts were not in use during the collision in

which the air bags were deployed.

PRELIMINARY CHECKS

1.

Check the seat belt warning lamp for proper operation as pen the following:

a.

Turn ignition switch ON. The seat belt warning lamp should illuminate.

b.

Fasten driver seat belt. The seat belt warning lamp should turn OFF.

2.

If the air bag warning lamp is blinking, perform self-diagnosis with CONSULT and air bag warning lamp.
Refer to

SRC-13, "Description"

.

3.

Check that the seat belt retractor, seat belt anchor and buckle bolts are tightened firmly.

4.

Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Check that guide
swivels freely and that webbing lays flat and does not bind in guide. Check that height adjuster operates
properly and holds securely.

5.

Check retractor operation:

a.

Fully extend the seat belt webbing and check for twists, tears and other damage.

b.

Allow the seat belt to retract. Check 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. Dirt build-up in the
loops of the upper anchors can cause the seat belts to retract slowly.

c.

Fasten the seat belt. Check that 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 (19.685 in) or more.

2.

Fix the seat belt at the center pillar webbing opening with a clip or other device.

3.

Pass a thin wire through the through-anchor webbing opening. Hold both ends of the wire and pull it
tightly while moving it up and down several times along the webbing opening surface to remove dirt
stuck there.

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.
NOTE:
Apply the tape so that there is no slack or wrinkling.

6.

Remove the clip fixing the seat belt and check that the webbing returns smoothly.

6.

Repeat steps above if necessary to check the other seat belts.

SEAT BELT RETRACTOR ON-VEHICLE CHECK

Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)

NOTE:
All seat belt retractors are Emergency Locking Retractors (ELR) type. In an emergency (sudden stop) the
retractor locks and prevent the webbing from extending any further. All 3-point type seat belt retractors except
the driver 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 with the following test(s) to determine if a retractor assembly is operating prop-
erly.

Grasp the shoulder webbing and pull forward quickly. The retractor should lock and prevent the belt from
extending further.

ALR Function Stationary Check

1.

Pull out the entire length of the seat belt from the 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 Retractors (ALR) mode.

3.

Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If it
does not operate normally, replace the retractor assembly.

4.

Allow the entire length of the webbing to retract to cancel the automatic locking mode.

ELR Function Moving Check

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. Never 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 that the
retractor does not lock.

1.

Fasten driver 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 sudden stop and the
driver and passenger must be prepared to brace themselves in the event that the retractor does not lock.
Apply brakes firmly and make a very hard stop.

During stopping, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock,
perform the retractor off-vehicle check.

SEAT BELT RETRACTOR OFF-VEHICLE CHECK

1.

Remove the seat belt retractor.
Remove the front seat belt assembly. Refer to

SB-5, "SEAT BELT RETRACTOR : Removal and Installa-

2.

SEAT BELT RETRACTOR ON-VEHICLE CHECK

Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)

NOTE:
All seat belt retractors are 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 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 with the following test(s) to determine if a retractor assembly is operating prop-
erly.

ELR Function Stationary Check

Grasp the shoulder webbing and pull forward quickly. The retractor should lock and prevent the belt from
extending further.

ALR Function Stationary Check

Pull out the entire length of the seat belt from the 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 Retractors (ALR) mode.

3.

Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If it
does not operate normally, replace the retractor assembly.

4.

Allow the entire length of the webbing to retract to cancel the automatic locking mode.

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

INFOID:0000000008460459

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never 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 for Procedure without Cowl Top Cover

INFOID:0000000008460460

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precaution for Battery Service

INFOID:0000000008460461

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

• Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll

over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative,
all maintenance must be performed by a NISSAN or INFINITI dealer.

• Before removing and installing the pop-up roll bar component parts and harness, always turn the

ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The
purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply
circuit in the air bag diagnosis sensor unit.)

• When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS

AIR BAG CONTROL warnings in the Service Manual.
