Seat Belt Inspection INFOID:0000000004307384
AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies in cluding 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 acci dent. Seat belt assemblies not in use during a colli-
sion should also be replaced if either damage or im proper operation is noted. Seat belt pre-tensioner
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, etc.)
• 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 seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal collision
in which the air bags are deployed.
PRELIMINARY CHECKS 1. Check the seat belt warning lamp/chime for proper operation as follows:
a. Switch ignition ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime should sound for about seven seconds.
b. Fasten driver's seat belt. The seat belt warni ng lamp should go out and the chime (if sounding) should
stop.
2. If the air bag warning lamp is blinking, conduct self-diagnosis using CONSULT-II, and air bag warning
lamp. Refer to SRS-19, " SRS Operation Check " .
3. Check 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. Make sure guide
swivels freely and that webbing lays flat and does not bind in guide. Make sure 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. Make sure 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 caus e the seat belts to retract slowly.
c. Fasten the seat belt. Check the seat belt returns sm oothly and completely to the retractor. If the webbing
does not return smoothly, the cause may be an accu mulation of dust or dirt. Use the “SEAT BELT TAPE
SET” and perform the following steps.
Inspect the front seat belt though-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 attach t he seat belt at the center pillar webbing opening.
3. Pass a thin wire though the D-ring 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 matter 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 though-anchor webbing opening. NOTE:
Apply the tape so that there is no looseness or wrinkling.
6. Remove the clip attaching the seat bel t and check that the webbing returns smoothly.
6. Repeat steps above as 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 of the Emergency Locki ng 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 Automati c 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 part ially, 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.
ELR Function Stationary Check Grasp the shoulder webbing and pull it forward quickly . The retractor should lock and prevent the belt from
extending further.

BATTERY
How to Handle Battery INFOID:0000000004306818
CAUTION:
• If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
• After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
• Never add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE The following precautions must be taken to prevent over-discharging
a battery.
• The battery surface (particularly its top) should always be kept clean and dry.
• The terminal connections should be clean and tight.
• At every routine maintenance, check the electrolyte level. This also applies to batteries designated as “low maintenance” and
“maintenance-free”.
• When the vehicle is not going to be used over a long period of time, disconnect the negative battery terminal.
• Check the charge condition of the battery. Periodically check the specific gr avity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL WARNING:
Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, do not touch or rub your eyes until yo u have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, imme diately flush with water for 15 minutes and seek medical attention. MEL041F

CHARGING SYSTEM
System Description INFOID:0000000004306825
The generator provides DC voltage to operate the vehicl e's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to generator terminal 3 through
• 10A fuse (No. 29, located in the fuse and fusible link box).
Power is supplied through terminal 1 to charge the batte ry and operate the vehicle's electrical system. Output
voltage is monitored at terminal 3 by the IC regulator. The charging circuit is protected by the 120A fusible link
[letter a , located in the fusible link box (battery)].
Ground is supplied
• to generator terminal 5
• through body ground F5, and
• through the generator case to the cylinder block
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 3, located in the fuse block (J/B)]
• to combination meter terminal 28 for the charge warning lamp.
The IC regulator controls ground to terminal 38 of the combination meter through terminal 2 of the generator.
When the ignition is turned on and power becomes availabl e at terminal 2, this "wakes up" the regulator. The
regulator monitors charge output and grounds terminal 2 or leaves it open depending on charge output. With
power and ground supplied, the charge warning lamp will il luminate. When the generator is providing sufficient
voltage, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.
