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

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.
