Introduction
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.
Ve h i c l e d a m a g e o r d r i v e a b i l i t y p r o b -
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.
Other fuels
Using fuel additives such as:
-Silicone fuel additive
-MMT (Magnanese, Mn) fuel additive
-Ferrocene (iron-based) fuel additive
-Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, dam-
age to the catalytic converter, or
abnormal corrosion, and may cause
damage to the engine resulting in a
reduction in the overall life of the
powertrain.
Damage to the fuel system or per-
formance problems caused by the
use of these fuels, may not be cov-
ered by your New Vehicle Limited
Warranty.
NOTICE
Never use fuel which contains
methanol. Discontinue use of
any petrol containing ethanol
which impairs drivability.

Te r t i a r y B u t y l E t h e r ) o v e r 1 5 . 0 % v o l .
(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

unleaded petrol which has an
Octane Rating of RON (Research
Octane Number) 91 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 at every 15,000km.
Additives are available from your
authorised HYUNDAI dealer along
