Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
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.
(Do not use methanol blended fuels.)
You may use unleaded petrol with an
octane rating of RON 91-94 / AKI 87-
90 but it may result in slight perform-
ance reduction of the vehicle.
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.
NOTICE
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.
CAUTION
•Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
•Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
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 speci-
fied (We recommend that you
consult a HYUNDAI authorised
repairer for details.)

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 additive
added to the fuel tank according to
the maintenance schedule is recom-
mended.
Additives are available from your
HYUNDAI authorised repairer along
with information on how to use them.
Do not mix other additives.

If you are going to drive your vehicle
in another country, be sure to:
• Observe all regulations regarding registration and insurance.

age to the fuel system and any
