AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies in cluding retractors and attached hardware after any collision.
NISSAN/INFINITI recommends that all seat belt assemblies in use during a collision be replaced
unless the collision was minor and th e belts show no damage and continue to operate properly. Fail-
ure to do so could result in seri ous personal injury in an accident. Seat belt assemblies not in use dur-
ing a collision should also be re placed if either damage or improper operation was noted. Seat belt
pre-tensioners should be replaced even if the seat be lts were not in use during a frontal collision in
which the air bags were deployed.
Replace any seat belt assembly (including anchor bolts) if:
 The seat belt is in use at the time of a collision (e xcept 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. to rn 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-tensioner must be replaced even if t he seat belts were not in use during the collision in
which the air bags are deployed.
PRELIMINARY CHECKS
1. Check that the seat belt retractor, s eat belt anchor and buckle bolts are tightened firmly.
2. Repeat step above if necessary to check the other seat belts.

< SYMPTOM DIAGNOSIS >
SQUEAK AND RATTLE TROUBLE DIAGNOSES
Most of these incidents can be repaired by adjusting, securing or insulating the 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 knocking noise
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 duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seats in and the load placed on the seat when
the noise occurs. These conditions should be duplicated 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 suspected components while duplicating the con-
ditions under which the noise occurs.Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the 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.
