CHASSIS AND BODY MAINTENANCE
Checking Seat Belts, Buckles, Retractors, Anchors and Adjusters
ELS001J7
Check the seat belt buckles, webbing, retractors, anchors and adjusters. Replace any seat belt assembly as
necessary. Refer toSB-11, "
Seat Belt Inspection".
lCheck the seat belt anchors for loose mounting bolts, damage, or excessive wear.
lCheck the seat belt webbing for any damage, cuts, fraying, or excessive wear.
lCheck the retractor for smooth operation.
lCheck the function of the buckles by inserting the seat belt tongue and checking for proper engagement of
the buckle and press the button on the buckle to check for proper release of the seat belt tongue.
CAUTION:
lAfter any collision, inspect all seat belt assemblies, including retractors and other attached com-
ponents, such as the guide rail set. NISSAN recommends replacing all seat belt assemblies in use
during a collision, unless they are not damaged and are inspected to confirm they are operating
properly after a minor collision.
Also inspect all seat belt assemblies that are not in use during a collision, and replace any compo-
nents if damaged or not operating properly. The seat belt pre-tensioner should be replaced even if
the seat belts are not in use during a frontal collision where the driver and passenger air bags
have been deployed.
lIf any component of the seat belt assembly is suspected of being damaged or not operating prop-
erly, do not repair the component. Replace the components as an assembly.
lIf the seat belt webbing is cut, frayed, or damaged then replace the seat belt assembly.
lNever lubricate the seat belt buckle or tongue.
lWhen replacing any seat belt assembly always use a Genuine NISSAN seat belt assembly.
Checking Body CorrosionELS001K3
Visually check body panels for collision damage (scratches, chipping, rubbing, etc.) or damage to the anti-cor-
rosion materials. In particular, check the following locations.
HEMMED PANELS
Hood front end, door lower end, trunk lid rear end, etc.
PANEL JOINT
Side sill of rear fender and center pillar, rear wheel housing of rear fender, around strut tower in engine com-
partment, etc.
PANEL EDGE
Trunk lid opening, sunroof opening, fender wheel-arch flange, fuel filler lid flange, around holes in panel, etc.
PARTS CONTACT
Waist moulding, windshield moulding, bumper, etc.
PROTECTORS
Damage or condition of mudguard, fender protector, chipping protector, etc.
ANTI-CORROSION MATERIALS
Damage or separation of anti-corrosion materials under the body.
DRAIN HOLES
Condition of drain holes at door and side sill. When repairing corroded areas, refer to the Corrosion Repair
Manual.

lA compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).
lAlways remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis
during a future service.
lDo not allow dye to come into contact with painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period
of time cannot be removed.
lDo not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
lDo not use more than one refrigerant dye bottle (1/4 ounce /7.4 cc) per A/C system.
lLeak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detector dye
in HFC-134a (R-134a) A/C systems or A/C system damage may result.
lThe fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction
occurs.
IDENTIFICATION
NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.
IDENTIFICATION LABEL FOR VEHICLE
Vehicles with factory installed fluorescent dye have this identification
label on the front side of hood.
