EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive Belts*:Check engine drive belts for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belts.
Engine Air Filter: Replace at specified in-
tervals. When driving for prolonged periods
in dusty conditions, check/replace the filter
more frequently.
Engine Coolant*: Replace coolant at the
specified interval. When adding or replac-
ing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (blue)
or equivalent with the proper mixture. (For
additional information on the proper mix-
ture for your area, see “Engine cooling sys-
tem” (P. 8-6)).
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
Engine Oil and Oil Filter: Replace engine
oil and oil filter at the specified intervals. For
recommended oil grade and viscosity see
“Recommended fluids/lubricants and ca-
pacities” (P. 10-2). Engine Valve Clearance*:
Inspect only if
valve noise increases. Adjust valve clear-
ance if necessary.
Evaporative Emissions Control Vapor
Lines*: Check vapor lines for leaks or loose-
ness. Tighten connections or replace parts
as necessary.
Fuel Lines*: Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place parts as necessary.
CHASSIS AND BODY
MAINTENANCE:
Brake Lines and Cables: Visually inspect
for proper installation. Check for chafing,
cracks, deterioration, and signs of leaking.
Replace any deteriorated or damaged
parts immediately.
Brake Pads and Rotors: Check for wear,
deterioration and fluid leaks. Replace any
deteriorated or damaged parts immedi-
ately.
Exhaust System: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary. In-Cabin Microfilter:
Replace at specified
intervals. When driving for prolonged peri-
ods in dusty conditions, replace the filter
more frequently.
Propeller Shaf t(s): Check for damage,
looseness, and grease leakage. (4WD/
AWD/RWD).
Steering Gear and Linkage, Axle and Sus-
pension Parts, Drive Shaf t Boots: Check
for damage, looseness, and leakage of oil
or grease. Under severe driving conditions,
inspect more frequently.
Tire Rotation: Rotate tires at the specified
interval shown in the maintenance sched-
ule. When rotating tires, check for damage
and uneven wear. Replace if necessary.
Transmission Fluid/Oil, Differential Oil,
Transfer Case Oil: Visually inspect for signs
of leakage at specified intervals.
Replace automatic transmission fluid at
specified intervals.
If towing a trailer, using a camper or car-top
carrier, or driving on rough or muddy roads:
• Replace the differential oil every 20,000 miles (32,000 km) or 24 months.
•
Replace the automatic transmission fluid
ever 30,000 miles (48,000 km) or 24 months.
