NOTICE
Damage to the fuel system or perfor-
mance problem caused by the use of

New Vehicle Limited Warranty.
Use of MTBE
Kia recommends avoiding fuels contain-
ing MTBE (Methyl Tertiary Butyl Ether)
over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and pro-
duce vapour lock or hard starting.
CAUTION
Your New Vehicle Limited Warranty may
not cover damage to the fuel system
and any performance problems that are
caused by the use of fuels containing
methanol or fuels containing MTBE
(Methyl Tertiary Butyl Ether) over 15.0%
vol. (Oxygen Content 2.7% weight.)
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system, engine control system
and emission control system.
Fuel additives
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 profes-
sional workshop along with information
on how to use them. Kia recommends to
visit an authorised Kia dealer/service
partner.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
僅 Observe all regulations regarding reg-
istration and insurance.
僅 Determine that acceptable fuel is
available.
