Maintenance Under Severe Driving Conditions
(Annual Driving Distance < 30,000 km/year)
=NJMA0043S03The 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.
A — Driving under dusty conditions
B — Driving repeatedly 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 areas or in 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

NOTE:
(1) First replace at 90,000 km (54,000 miles), then every 60,000 km (36,000miles). Perform “I” (checking the mixture ratio and
correcting the mixture ratio if necessary) at the middle of replacement interval.
(2) Periodic maintenance is not required. However, if valve noise increases, check valve clearance.
(3) Fuel filter is maintenance-free. For service procedures, refer to FE section.
(4) 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.
★Maintenance items with “★” should be performed more frequently according to “Maintenance Under Severe Driving Con-
ditions”.
