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 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 malfunc-
tion or engine damage.

tion or engine damage.
Recommend that the coolant be replaced by an authorised Kia
dealer/service partner.
Inspect HSG belt for evidence of cuts, cracks, excessive wear or oil
saturation and replace if necessary.
For your convenience, it can be replaced prior to it's interval when
you do maintenance of other items.
Differential oil should be changed anytime it has been submerged in
water.
Transfer case oil should be changed anytime it has been sub-
merged 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 should be 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/service
partner. Do not mix other additives.
