FUEL REQUIREMENTS
F8
Introduction
Petrol engine
Unleaded
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. (Do not use methanol
blended fuels.)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.
Petrol containing ethanol
Ethanol [E-10], a mixture of petrol
and ethanol (also known as grain
alcohol), is marketed along with or
instead of leaded or unleaded petrol.
Do not use petrol containing more
than 10% ethanol, and do not use
petrol or ethanol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using ethanol of any
kind if driveability problems occur.
Vehicle damage or driveability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Petrol containing more than 10%
ethanol.
2. Petrol or ethanol containing
methanol.
3. Leaded fuel or leaded ethanol.
•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.
WARNING
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 HYUNDAI
dealer for details.)
CAUTION

Introduction
Other fuels
Using fuels such as;
- Silicone (Si) contained fuel,
- MMT (Manganese, Mn) contained
fuel,
- Ferrocene (Fe) contained fuel, and
- Other metallic additives contained
fuels,
may cause vehicle and engine dam-
age or cause plugging, misfiring,
poor acceleration, engine stalling,
catalyst melting, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.Damage to the fuel system or per-
formance problem caused by the
use of these fuels may not be cov-
ered by your New Vehicle Limited
Warranty.
Use of MTBE
HYUNDAI recommends avoiding
fuels containing 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
produce vapour lock or hard starting.
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damage
components of the fuel system,
engine control system and emission
control system.
Fuel Additives
HYUNDAI recommends that you use
unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index)
87 or higher.
For customers who do not use good
quality petrols including fuel addi-
tives regularly, and have problems
starting or the engine does not run
smoothly, add one bottle of additives
to the fuel tank every 15,000 km.
Additives are available from your
authorised HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
NOTICE
Your New Vehicle Limited
Warranty may not cover dam-
age to the fuel system and any
performance problems that are
caused by the use of fuels con-
taining methanol or fuels con-
taining MTBE (Methyl Tertiary
Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight.)
CAUTION
Never use fuel which contains
methanol. Discontinue use of
any petrol containing ethanol
which impairs drivability.
