FUEL REQUIREMENTS
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 minimize exhaust
emissions and spark plug fouling.
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 (We recommend
that you consult an authorized
HYUNDAI dealer for details.)
WARNING
• Do not “top off” after the nozzle
automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.

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
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 damage to the
fuel system, engine control system and
emission control system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or driveability
problems 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.
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs
drivability.
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 damage
or cause plugging, misfiring, poor
acceleration, engine stalling, catalyst
melting, abnormal corrosion, life cycle
reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
NOTICE
Damage to the fuel system or
performance problem caused by the
use of these fuels may not be covered
by your New Vehicle Limited Warranty.

Introduction
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 vapor lock or hard starting.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the
fuel system and any performance
problems that are caused by the use
of fuels containing methanol or fuels
containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight.)
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) 91 / AKI (Anti-Knock Index) 87
or higher.
For customers who do not use good
quality petrols including fuel additives
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 km.
Additives are available from your
authorized HYUNDAI dealer 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.

Diesel engine
Diesel fuel
Diesel engine must be operated only on
commercially available diesel fuel that
complies with EN 590 or comparable
standard. (EN stands for “European
Norm”). Do not use marine diesel fuel,
heating oils, or non-approved fuel
additives, as this will increase wear and
cause damage to the engine and fuel
system. The use of non-approved fuels
and / or fuel additives will result in a
limitation of your warranty rights.
Diesel fuel of above cetane 51 is used
in your vehicle. If two types of diesel
fuel are available, use summer or winter
fuel properly according to the following
temperature conditions.
• Above -5°C (23°F) ... Summer type
diesel fuel.
• Below -5°C (23°F) ... Winter type diesel
fuel.
Watch the fuel level in the tank very
carefully : If the engine stop s through
fuel failure, the circuits must be
completely purged to permit restarting.
CAUTION
Do not let any petrol or water enter the
tank. This would make it necessary to
drain it out and to bleed the lines to
avoid jamming the injection pump and
damaging the engine.
CAUTION
Diesel Fuel (if equipped with DPF)
It is recommended to use the regulated
automotive diesel fuel for diesel vehicle
equipped with the DPF system.
If you use diesel fuel including high
sulfur (more than 50 ppm sulfur) and
unspecified additives, it can cause the
DPF system to be damaged and white
smoke can be emitted.
Biodiesel
Commercially supplied Diesel blends of
no more than 7% biodiesel, commonly
known as “B7 Diesel” may be used
in your vehicle if Biodiesel meets EN
14214 or equivalent specifications. (EN
stands for “European Norm”). The use
of biofuels exceeding 7% made from
rapeseed methyl ester (RME), fatty
acid methyl ester (FAME), vegetable oil
methyl ester (VME) etc. or mixing diesel
exceeding 7% with biodiesel will cause
increased wear or damage to the engine
and fuel system. Repair or replacement
of worn or damaged components due to
the use of non approved fuels will not be
covered by the manufactures warranty.
CAUTION
• Never use any fuel, whether diesel,
B7 biodiesel or otherwise, that fails
to meet the latest petroleum industry
specification.
• Never use any fuel additives
or treatments that are not
recommended or approved by the
vehicle manufacturer.
