Fuel requirements

Unleaded petrol
For Europe
For the optimal vehicle performance, we
recommend you to use unleaded petrol
with 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 performance
reduction of the vehicle. (Do not use
methanol blended fuels.)
Except Europe
Your new Kia vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane Num -
ber) 91/AKI (Anti- Knock Index) 87 or
higher. (Do not use methanol blended
fuels.)
Your new vehicle is designed to obtain
maximum performance with unleaded
fuel, as well as minimize exhaust emis -
sions and spark plug fouling.
WARNING
僅 Do not "top off" after the nozzle auto -
matically shuts off when refuelling.
僅 Always check that the fuel cap is
installed securely to prevent fuel spill -
age in the event of an accident.
CAUTION
Never use leaded fuel. The use of leaded
fuel is detrimental to the catalytic con -
verter and will damage the engine con -
2 2
trol 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 recommends to
consult an authorised Kia dealer/service
partner for details.
Petrol containing alcohol and
methanol
Gasohol, a mixture of petrol and ethanol
(also known as grain alcohol), and petrol
or gasohol containing methanol (also
known as wood alcohol) are being mar -
keted along with or instead of 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 drivabil -
ity problems and damage to the fuel
system, engine control system and emis -
sion control system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufac -
turer's warranty if they result from the
use of:
1. Gasohol containing more than 10%
ethanol.
2. Petrol or gasohol containing metha -
nol.
3. Leaded fuel or leaded gasohol.
CAUTION
Never use gasohol which contains meth -
anol. Discontinue the use of any gasohol
product which impairs drivability.
