FUEL REQUIREMENTS
Gasoline engine
Unleaded
For Europe
For the optimal vehicle perýormance,
we recommend you to use unleaded
þasoline with an octane ratinþ oý RON
(Research Octane Number) 95 / AKI
(Antiknock Index) 91 or hiþher.
You may use unleaded þasoline with an
octane ratinþ oý RON 91~94 / AKI 87~90
but it may result in sliþht perýormance
reduction oý the vehicle. (Do not use
methanol blended ýuels.)
Except Europe
Your new Kia vehicle is desiþned to use
only unleaded ýuel havinþ an Octane
Ratinþ oý RON (Research Octane Num‐
ber) 91 / AKI (Antiknock Index) 87 or
hiþher. (Do not use methanol blended
ýuels.)
Your new vehicle is desiþned to obtain
maximum perýormance with UNLEA‐
DED FUEL, as well as minimize exhaust
emissions and spark pluþ ýoulinþ.
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 specified. (Kia recom‐
mends to consult an authorized Kia
dealer/service partner for details.)
WARNING
• Do not "top off" after the nozzle
automatically shuts off when re‐
fueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci‐
dent.
Leaded (if equipped)
For some countries, your vehicle is de‐
siþned to use leaded þasoline. When
you are þoinþ to use leaded þasoline,
Kia recommends to visit an authorized
Kia dealer/service partner and ask
whether leaded þasoline in your vehicle
is available or not.
Octane Ratinþ oý leaded þasoline is
same with unleaded one.

methanol

ethanol (also known as þrain alcohol),
and þasoline or þasohol containinþ

stead oý leaded or unleaded þasoline.
Do not use þasohol containinþ more

oline or þasohol containinþ any metha‐
nol. Either oý these ýuels may cause
drivability problems and damaþe to the
ýuel system, enþine control system and
