Petrol engine
Unleaded
For the optimal vehicle performance,
we recommend you use unleaded
petrol which has an octane rating of
RON (Research Octane Number) 95
/ AKI (Anti Knock Index) 91 or higher.
You may use unleaded petrol with an
octane rating of RON 91-94 / AKI
87-90 but it may result in slight perfor-
mance reduction of the vehicle. (Do
not use methanol blended fuels)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mise 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 sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system clean-
ing agents to the fuel tank other
than what has been specified (We
recommend that you consult a
HYUNDAI authorised repairer for
details.)

Foreword
Vehicle damage or driveability prob-
lems may not be covered by the man-
ufacturer’s warranty if they result from
the use of:
1. Gasohol containing more than
10% ethanol.
2. Petrol or gasohol containing meth-
anol.
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 fuel additives such as:
- Silicone fuel additive
- MMT (Magnanese, Mn) fuel addi-
tive
- Ferrocene (iron-based) fuel addi-
tive
- Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, damage
to the catalyst, or abnormal corro-
sion, and may cause damage to the
engine resulting in a reduction in the
overall life of the powertrain.
NOTICE
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.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuel
system and any performance prob-
lems 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) 95 / AKI (Anti Knock Index)
91 or higher (for Europe) or Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index)
87 or higher (except Europe).
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 additive added to the
fuel tank according to the mainte-
nance schedule is recommended
(refer to chapter 8, “Normal
Maintenance Schedule”).
Additives are available from your
HYUNDAI authorised repairer along
with information on how to use them.
Do not mix other additives.
