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 — Extensive idling
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:
● Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.
●(1)Periodic maintenance is not required. However, if valve noise increases, check valve clearance.
●(2) Replace the drive belts if found damaged or if the auto belt tensioner reading reaches the maximum limit.
●(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.
●(4) Fuel filter is maintenance-free. For service procedures, refer to FL section.
●(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.

ENGINE MAINTENANCE (QR20DE·QR25DE)
●Replace the radiator cap if there is an abnormality in the negative-pressure valve, or if the open-valve
pressure is outside of the standard values.
CHECKING RADIATOR SYSTEM FOR LEAKS
To check for leakage, apply pressure to the cooling system with a
tester.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure engine coolant escaping
from the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
Checking Fuel LinesELS000JX
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.
Fuel Hose Clamp
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.
Changing Air Cleaner FilterELS000JY
VISCOUS PAPER TYPE
The viscous paper type filter does not need cleaning.
DRY PAPER TYPE
It is necessary to clean the filter or replace it at the recommended intervals, more often under dusty driving
conditions.Testing pressure:

REMOVAL
1. Remove air duct and upper air cleaner case.
2. Remove fuel filter protector.
3. Remove fuel hoses from 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:
●Replace O-ring on drain plug with new one.
●Screw the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning
approximately 2/3 turn.
●After installation, bleed air from fuel path. Refer to FL-16, "Air Bleeding" .
●Check for fuel leakage with running engine.

VISCOUS PAPER TYPE
The viscous paper type air cleaner filter does not require any clean-
ing operation between renewal.
Changing Engine OilELS000CH
WARNING:
●Be careful not to burn yourself, as the engine oil is hot.
●Prolonged and repeated contact with used engine oil may
cause skin cancer: try to avoid direct skin contact with
used engine oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine
oil leakage from engine components.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain engine oil.
●Install drain plug and refill with new engine oil.
Engine oil specification and viscosity:
●API grade CF-4.
●ACEA B1, B3, B4, B5
●Refer to MA-16, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Engine oil capacity (Approximate):
●The refill capacity depends on the engine oil temperature and drain time. Use these specifications for
reference only.
Always use the dipstick to the determine when the proper amount of engine oil is in the engine.
CAUTION:
●Be sure to clean drain plug and install with new washer.
●The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
Always use the dipstick to the determine when the proper amount of engine oil is in the
engine.
5. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
6. Stop engine and wait for 10 minutes.
7. Check engine oil level. Refer to LU-18, "
ENGINE OIL" .
