Introduction
Petrol engine
Unleaded
Your new HYUNDAI 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 minimise exhaust emis-
sions and spark plug fouling.
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 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 prob-
lems and damage to the fuel system,
engine control system and emission con-
trol system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or driveability problems
may not be covered by the manufactur-
er’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.
FUEL REQUIREMENTS
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’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 rec-
ommend that the system be con-
sulted by a HYUNDAI authorised
repairer.)
WARNING
• Do not "top off" after the nozzle
automatically shuts off when
refuelling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.

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 accel-
eration, 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 perform-
ance problem caused by the use of these
fuels may not be covered by your New
Vehicle Limited Warranty.
Use of MTBE
HYUNDAI recommends that fuels con-
taining MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight) should not be used 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 alco-
hol) should not be used. This type of fuel
can reduce vehicle performance and
damage components of the fuel 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 miles (15,000 km).
Additives are available from your
HYUNDAI authorised repairer along with
information on how to use them. Do not
mix other additives.
CAUTION
The New Vehicle Warranty does not
cover damage to the fuel system or
any performance problems 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).
