As it is normal for engine oil to be consumed during driving, the engine oil
level should be checked on regular basis.
The engine oil change interval for normal operating conditions is based on
the use of the recommended engine specification. If the recommended
engine oil specification is not used, then replace the engine oil according
to the maintenance schedule under severe operating conditions.
When adding coolant, use only deionised water or soft water for your vehi-
cle and never mix hard water in the coolant filled at the factory. An improper
coolant mixture can result in serious malfunction or engine damage.

Recommend that the coolant be replaced by an authorised Kia dealer/ser-
vice partner.
Inspect HSG belt for evidence of cuts, cracks, excessive wear or oil saturation
and replace if necessary.

maintenance of other items.
Differential oil should be changed anytime it has been submerged in water.

Kia recommends that you use unleaded petrol which has an octane rating of
RON (Research Octane Number) 95 / AKI (Anti Knock Index) 91 or higher (for
Europe) or Octane Rating of RON (Research Octane Number) 91 / AKI (Anti-
Knock Index) 87 or higher (except Europe).
For customers who do not use good quality petrols including fuel additives
regularly, and have problems starting or the engine does not run smoothly,
one bottle of additives added to the fuel tank when the engine oil is replaced.
Additives are available from a professional workshop along with information
on how to use them. Kia recommends to visit an authorised Kia dealer/ser-
vice partner. Do not mix other additives.
