Introduction
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you use unleaded
gasoline which has an octane rating
of RON (Research Octane Number)
95 / AKI (Anti Knock Index) 91 or
higher. (Do not use methanol blend-
ed fuels.)
You may use unleaded gasoline with
an octane rating of RON 91~94/AKI
87~90 but it may result in slight per-
formance reduction of the vehicle.
Except Europe
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 mini-
mize exhaust emissions and spark
plug fouling.
FUEL REQUIREMENTS
WARNING
• Do not "top off" after the noz-
zle automatically shuts off
when refueling.
• Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
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 speci-
fied. (Consult an authorized
HYUNDAI dealer for details.)

Introduction
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 gasoline 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 gasoline 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
15,000km (for Europe)/5,000km
(except Europe). Additives are avail-
able from your authorized HYUNDAI
dealer along with information on how
to use them.
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.No special break-in period is need-
ed. By following a few simple precau-
tions for the first 1,000 km (600 miles)
you may add to the performance,
economy and life of your vehicle.
• Do not race the engine.
• While driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
• Do not maintain a single speed for
long periods of time, either fast or
slow. Varying engine speed is
needed to properly break-in the
engine.
• Avoid hard stops, except in emer-
gencies, to allow the brakes to seat
properly.
• Don't tow a trailer during the first
2,000 km (1,200 miles) of opera-
tion.
