SQUEAK AND RATTLE TROUBLE DIAGNOSES
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
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 can often be traced to one of the following items:
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 is important to note t he position the seat is in and the load placed on the seat
when the noise occurs. These conditions should be duplic ated when verifying and isolating the cause of the
noise.
Causes 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 thes e 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.

UNDER THE HOOD AND VEHICLE
The maintenance items listed here should
be checked periodically (e.g. each time you check the engine oil or refuel).
Seats Check seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restrains move up and down smoothly and that the
locks (if equipped) hold securely in all latched positions. Check that the latches
lock securely for folding-down rear seatbacks. —
Seat belts Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage. MA-34
Accelerator pedal
Check the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal. —
Brakes Check that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to
keep the floor mats away from the pedal. BR-7
BR-15
Parking brake
Check that the lever or pedal has the proper travel and make sure that the ve-
hicle is held securely on a fairly steep hill when only the parking brake is ap-
plied. PB-3
Automatic transmis-
sion “Park” mecha-
nismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the
selector lever in the P (Park) position without applying any brakes.

Windshield washer
fluid Check that there is adequate fluid in the tank. —
Engine coolant level Check the coolant level when the engine is cold. MA-12
Radiator and hosesCheck the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation, de-
terioration or loose connections. MA-16
Brake fluid levels
Make sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir(s). MA-28
Battery
Check the fluid level in each cell. It should be between the “MAX” and “MIN”
lines. Vehicles operated in high temperatures or under severe conditions re-
quire frequent checks of the battery fluid level. PG-159
Engine drive belts
Make sure that no belt is frayed, worn, cracked or oily. MA-12
Engine oil levelCheck the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine. LU-7
Power steering fluid
level and linesCheck the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.
MA-32
Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it. MA-21
Underbody
The underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate. —
Fluid leaks Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately. —

AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including 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-tensioners must be replaced even if t he 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 per 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-III and air bag warning lamp. Refer to SRC-14, "
Description".
3. Check that the seat belt retractor, s eat 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 c heck for twists, tears or other damage.
b. Allow the seat belt to retract. Check that webbing retu rns 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 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. 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 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 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.
