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 Rat -
ing 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 at every 15,000 km
(10,000 miles) (for Europe, Australia and New Zealand) /
10,000 km (6,500 miles) (except Europe, Australia and New
Zealand, China, Brazil) / 5,000 km (3,000 miles) (for China,
Brazil). Additives are available from a professional workshop
along with information on how to use them. Kia recom -
mends to visit an authorised Kia dealer/service partner. Do
not mix other additives.
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 condi -
tions is based on the use of the recommended engine spec -
ification. If the recommended engine oil specification is not
used, then replace the engine oil according to the mainte -
nance 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 cool -
ant filled at the factory. An improper coolant mixture can
result in serious malfunction or engine damage.
For your convenience, it can be replaced prior to it's interval
when you do maintenance of other items.
Manual transmission fluid (or Dual clutch transmission
(DCT) fluid) should be changed anytime it has been sub -
merged in water.
