The following tables show the normal maintenance schedule. Depending upon weather and atmospheric
conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent
maintenance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.

performed on the following items as shown in the table.
A Ð Driving in dusty conditions
B Ð Repeatedly driving short distances
C Ð Towing a trailer or caravan
D Ð Extensive idling
E Ð Driving in extremely adverse weather conditions or in areas where ambient temperatures are either
extremely low or extremely high
