僅 As it is normal for engine oil to be consumed during driving, the engine oil level
should be checked on regular basis.
僅 The engine oil change interval for normal operating conditions is based on the use
of the recommended engine specification. If the recommended engine oil specifica-
tion is not used, then replace the engine oil according to the maintenance schedule
under severe operating conditions.
僅 Never add any additives to the engine oil. Engine oil additives can change the prop-
erties of engine oil and may cause serious engine failure.
僅 The engine oil level should be checked regularly and maintained properly. Operat-
ing with an insufficient amount oil can damage the engine, and such damage is not
covered by warranty.
僅 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 serious malfunction or engine damage.
僅 Adjust alternator, water pump and air conditioner drive belt. Inspect and if necessary
repair or replace.
僅 Inspect drive belt tensioner, idler and alternator pulley and if necessary correct or
replace.
For your convenience, it can be replaced prior to it's interval when you do maintenance
of other items.

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 more frequently. If there are some important safety matters
like fuel flow restriction, surging, loss of power, hard starting problem etc., replace the
fuel filter immediately regardless of maintenance schedule and consult a professional
workshop for more details. Kia recommends to consult an authorised Kia dealer/service
partner.
