• The engine oil level should be checked regularly and maintained properly. Operating with
an insufficient amount oil can damage the engine, and such damage is not covered by
warranty.
• This maintenance schedule depends on fuel quality. It is applicable only when using a
qualified fuel <"EN590 or equivalent">. If the diesel fuel specifications don't meet the
EN590, it must be replaced according to the severe maintenance schedule.
When adding coolant, use only deionized water or soft water for your vehicle and never mix
hard water in the coolant filled at the factory. An improper coolant mixture can result in seri-
ous malfunction or engine damage.
• Adjust alternator, water pump and air conditioner (if equipped) drive belt. Inspect and if
necessary repair or replace.
• Inspect drive belt tensioner, idler and alternator pulley and if necessary correct or
replace.
