formed on the following items as shown in the table.
Severe driving conditions
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 temperatures
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
I Ð Driving with frequent use of braking or in
mountainous areas
J Ð Frequent driving in water
