Maintenance Under Severe Driving
Conditions (Annual Driving Distance < 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
performed on the following items as shown in the table.
A Ð Driving under dusty conditions
B Ð Driving repeatedly short distances
C Ð Towing a trailer or caravan
D Ð Extensive idling
E Ð Driving in extremely adverse weather condi-
tions or in areas where ambient tempera-
tures are either extremely low or extremely
high
F Ð Driving in high humidity areas or in mountain-
ous areasG Ð Driving in areas using salt or other corrosive
materials
H Ð Driving on rough and/or muddy roads or in
the desert
