Checking Power Steering Fluid and LinesNLS0008E
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80
C (122 to 176F)
or “COLD” range at fluid temperatures of 0 to 30
C (32 to 86F).
CAUTION:
Do not overfill.
Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.
Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsNLS0008F
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.
Shake each wheel to check for excessive play.
Check wheel bearings for smooth operation.
Check axle and suspension nuts and bolts for looseness.
Check strut (shock absorber) for oil leakage or other damage.
Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.

Checking Seat Belt, Buckles, Retractors, Anchors and AdjustersNLS0008I
CAUTION:
After any collision, inspect all seat belt assemblies, including retractors and other attached hard-
wares (I.e. anchor bolt, guide rail set). Nissan recommends to replace all seat belt assemblies in
use during a collision, unless not damaged and properly operating after minor collision.
Also inspect seat belt assemblies not in use during a collision, and replace if damaged or improp-
erly operating.
Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal col-
lision where the driver and passenger air bags are deployed.
If any component of seat belt assembly is questionable, do not repair.
Replace as seat belt assembly.
If webbing is cut, frayed, or damaged, replace belt assembly.
Never oil tongue and buckle.
Use a genuine NISSAN seat belt assembly.
For details, refer to SB-33, "
Seat Belt Inspection" in SB section.
Check anchors for loose mounting
Check belts for damage
Check retractor for smooth operation
Check function of buckles and tongues when buckled and released
