MAINTENANCE UNDER SEVERE DRIVING CONDITIONS
(Annual Mileage <30,000 Km/year)
The maintenance intervals shown on the preceding pages are for normal operating conditions. If the vehicle is
mainly operated under severe driving conditions as shown below, more frequent maintenance must be per-
formed on the following items as shown in the table.
Severe driving conditions
A — Driving in dusty conditions
B — Repeatedly driving short distances
C — Towing a trailer or caravan
D—Extensiveidling
E — Driving in extremely adverse weather conditions or in areas where ambient temperatures are either
extremely low or extremely high
F — Driving in high humidity or mountainous areas
G — Driving in areas using salt or other corrosive materials
H — Driving on rough and/or muddy roads or in the desert
I — Driving with frequent use of braking or in mountainous areas
J — Frequent off road use or driving in water
K —Sustained high speed driving
L — For models without Euro-OBD system

PERIODIC MAINTENANCE
NOTE:
lMaintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.
l(1)Periodic maintenance is not required. However, if valve noise increases, check valve clearance.
l(2) Replace the drive belts if found damaged or if the auto belt tensioner reading reaches the maximum limit.
l(3) First replace at 90,000 Km (54,000 miles), then every 60,000 km (36,000 miles). Perform "I" (Checking the mixture ratio
and correcting the mixture ratio if necessary) at the middle of replacement interval.
l(4) Fuel filter is maintenance-free. For service procedures, refer to FL section.
l(5) Perform only according to "Maintenance Under Severe Driving conditions" for models without Euro-OBD system. For
models with Euro-OBD system, periodic maintenance is not required.

*1: For further details, see “SAE Viscosity Number”.
*2: Never use API CG-4.
*3: Use Genuine Nissan Anti-freeze Coolant (L2N)] or equivalent in its quality, in order to avoid possible aluminum corrosion within the
engine cooling system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be
covered by the warranty even if such incidents occurred during the warranty period.
*4: Contact a Nissan dealership for more information regarding suitable fluids, including recommended brand(s) of Dexron

CHECKING COOLING SYSTEM FOR LEAKS
lTo check for leakage, apply pressure to the cooling system with
atester.
WA RN ING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
Checking Fuel LinesELS000AQ
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration. If nec-
essary, repair or replace faulty parts.
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber hose clamps.
Ensure that screw does not contact adjacent parts.

lCheck radiator cap relief pressure.
lWhen connecting the radiator cap to the tester, apply water or

lReplace the radiator cap if there is an unusualness in the nega-
tive-pressure valve, or if the open-valve pressure is outside of
the standard values.
CHECKING COOLING SYSTEM FOR LEAKS
lTo check for leakage, apply pressure to the cooling system with
atester.
WAR NIN G:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.

3. Disconnect fuel hoses at fuel filter bracket.
CAUTION:
Plug the pipe to prevent fuel from draining.
4. Remove fuel filter with bracket.
CAUTION:
Do not splash fuel during removal. If fuel is splashed,
immediately wipe it off.
5. Using band-type filter wrench (commercial service tool), remove
fuel filter.
6. Turn fuel filter upside down to drain fuel.
7. Remove drain plug from fuel filter.
INSTALLATION
Install in reverse order of removal, paying attention to following:
lReplace O-ring on drain plug with new one.
lScrew the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning
approximately 2/3 turn.
lAfter installation, bleed air from fuel path. Refer toFL-16, "Air Bleeding".
