(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace drive belts if da
maged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, go to the FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and inte rvals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.

age.
Checking Power Steering Fluid and LineINFOID:0000000001606194
CHECKING FLUID LEVEL
• Check the power steering fluid level with the engine off.
• Check fluid level on reservoir. Use “HOT” range at fluid tempera- tures of 50 ° to 80° C (122° to 176° F). Use “COLD” range at fluid
temperatures of 0 ° to 30° C (32° to 86° F).
CAUTION:
• Do not overfill.
• Refer to MA-12, "
Fluids and Lubricants" .
CHECKING LINES
• Check lines for improper attachment, leaks, cracks, damage, loose
connections, chafing, and deterioration.
Checking Axle and Suspension PartsINFOID:0000000001606195
FRONT AND REAR AXLE AND SUSPENSION PARTS
Check front and rear axle and suspension parts for excessive play, cracks, wear or other damage.
• Shake each wheel to check for excessive play.
• Rotate each wheel to check for abnormal noise.
