Octane Number) 95 / AKI (Anti Knock
Index) 91 or higher.
You may use unleaded gasoline with an
octane rating of RON 91~94/AKI 87~90
but it may result in slight performance
reduction of the vehicle.

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.
Your new vehicle is designed to obtain

FUEL REQUIREMENTS

13
Introduction
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability 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. Gasoline or gasohol containing
methanol.
3. Leaded fuel or leaded gasohol.
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline. When
you are going to use leaded gasoline,
ask to an authorized HYUNDAI dealer
whether leaded gasoline in your vehicle
is available or not.
Octane Rating of leaded gasoline is
same with unleaded one.
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 acci-
dent.
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. (Consult
an authorized HYUNDAI dealer for
details.)
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.

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.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
Fuel Additives
HYUNDAI recommends that you use
good quality gasoline that meets Europe
Fuel standards (EN228) or equivalents.
For customers who do not use good
quality gasoline 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 15,000km (for Europe)/5,000km
(except Europe). Additives are available
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 reg-
istration and insurance.
• Determine that acceptable fuel is avail-
able.No special break-in period is needed. By
following a few simple precautions 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 emergen-
cies, to allow the brakes to seat prop-
erly.
• Don't let the engine idle longer than 3
minutes at one time.
• Don't tow a trailer during the first 2,000
km (1,200 miles) of operation.
VEHICLE BREAK-IN PROCESS
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.)
