Introduction
FOREWORD
Congratulations, and thank you for choosing HYUNDAI. We are pleased to welcome
you to the growing number of discerning people who drive HYUNDAIs.We are very
proud of the advanced engineering and high-quality construction of each HYUNDAI
we build.
Your Owner’s Manual will introduce you to the features and operation of your new
HYUNDAI. To become familiar with your new HYUNDAI, so that you can fully enjoy it,
read this Owner’s Manual carefully before driving your new vehicle.
This manual contains important safety information and instructions intended to
familiarize you with your vehicle’s controls and safety features so you can safely
operate your vehicle.
This manual also contains information on maintenance designed to enhance safe
operation of the vehicle. It is recommended that all service and maintenance on your
car be performed by a HYUNDAI authorised repairer. HYUNDAI dealers are prepared
to provide high-quality service, maintenance and any other assistance that may be
required.
This Owner’s Manual should be considered a permanent part of your vehicle, and
should be kept in the vehicle so you can refer to it at any time. The manual should
stay with the vehicle if you sell it to provide the next owner with important operating,
safety and maintenance information.
HYUNDAI MOTOR COMPANY
CAUTIONSevere engine and transmission damage may result from the use of poor quality
fuels and lubricants that do not meet HYUNDAI specifications. You must always use
high quality fuels and lubricants that meet the specifications listed on Page 2-14 in
the Vehicle Specifications section of the Owner’s Manual.

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 performance 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 minimise 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 system’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 recommend that you consult a HYUNDAI authorised repairer for
details.)
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 accident.

Introduction
Leaded (if equipped)
For some countries, your vehicle is designed to use leaded petrol. When you are going
to use leaded petrol, we recommend that you ask a HYUNDAI authorised repairer.
Octane rating of leaded petrol is same with unleaded one.
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 marketed 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 problems
and damage to the fuel system, engine control system and emission control system.
Discontinue using gasohol of any kind if drivability problems occur.
Vehicle damage or driveability problems may not be covered by the manufacturer’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.
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 additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor acceleration, engine stalling, damage to the
catalyst, or abnormal corrosion, 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 performance problem caused by the use of these
fuels may not be covered 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 problems 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 maintenance schedule is
recommended.
Additives are available from your HYUNDAI authorised repairer along with information
on how to use them. Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle in another country, be sure to:
