Introduction
Petrol engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you to use unleaded
petrol which complies with EN 228
and has an octane rating of RON
(Research Octane Number) 95 / AKI
(Anti Knock Index) 91 or higher. You
may use unleaded petrol with an
octane rating of RON 91-94 / AKI 87-
90 but it may result in slight perform-
ance reduction of the vehicle.
Except Europe
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index)
87 or higher.
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded petrol. When
you are going to use leaded petrol,
we recommend that you ask an
authorised Kia dealer whether lead-
ed petrol in your vehicle is available
or not.
Octane Rating of leaded petrol is
same with unleaded one.
Petrol containing alcohol and
methanol
Gasohol, a mixture of petrol and
ethanol (also known as grain alco-
hol), and petrol or gasohol containing
methanol (also known as wood alco-
hol) are being marketed along with or
instead of leaded or unleaded petrol.
Do not use gasohol containing more
than 10% ethanol, and do not use
petrol or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system.
Discontinue using gasohol of any
kind if drivability problems occur.
FUEL REQUIREMENTS
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental
to the catalytic converter and
will damage the engine control
system’s oxygen sensor and
affect emission control.
Never add any fuel system
cleaning agents to the fuel tank
other than what has been speci-
fied. (We recommend that you
consult an authorised Kia deal-
er for details.)
WARNING
• Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
• Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
