SQUEAK AND RATTLE TROUBLE DIAGNOSES
Most of these incidents can be repaired by adjusting, securing or insulatingthe item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area c an often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knockingnoise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicatingthe conditions can isolate most of these
incidents. Repairs usually consistof insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the pos ition the seatis in and the load placed on the seat when
the noise is present. These conditionsshould be duplic ated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspectedcomponents while duplicating the condi-
tions under which the noise occurs.Most of these incidents can be repaired by repositioning the component
orapplying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or onthe engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the \
vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

Seat Belt InspectionINFOID:0000000001327737
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 ei ther 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 acci dent. 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 collision
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 warni ng 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-23, "
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 c heck 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 insi de 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 sm oothly 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 wir e can be removed by cleaning the opening with a clean
cloth.
5. Apply tape at the point where the webbi ng contacts the through-anchor webbing opening.
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.
