Petrol containing alcohol andmethanol
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, engine con-
trol system and emission control sys-
tem.
Discontinue using gasohol of any
kind if drivability 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. Gasohol containing more than
10% ethanol.
2. Petrol or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
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 catalyst, or abnormal cor-
rosion, 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 problem caused by the
use of these fuels may not be cov-
ered by your New Vehicle Limited
Warranty.
NOTICE
F7
Introduction
Never use fuel which contains
methanol. Discontinue use of
any petrol product which
impairs drivability.
CAUTION

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 petrol which has an octane
rating of RON (Research Octane
Number) 95 / AKI (Anti Knock Index)
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, one bottle of additives
added to the fuel tank at every
10,000 miles (15,000km).
Additives are available from your
HYUNDAI authorised repairer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
• Observe all regulations regarding registration and insurance.
• Determine that acceptable fuel is available.
