FUEL REQUIREMENTS

Gasoline engine

Unleaded

Your new vehicle is designed to use only unleaded fuel having an octane number

((R+M)/2) of 87 (Research Octane Number 91) or higher. (Do not use methanol blended

fuels)

Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,

as well as minimize exhaust emissions and spark plug fouling.

NOTICE

To prevent damage to the engine and engine components, never add any fuel

system cleaning agents to the fuel tank other than what has been specified.

Consult an authorized HYUNDAI dealer for additional information.

WARNING

śꢀ Do not “top off” after the nozzle automatically shuts off when refueling.

śꢀ Always check that the fuel cap is installed securely to prevent fuel spillage in the

event of an accident.

Gasoline containing alcohol and methanol

Gasohol, a mixture of gasoline and ethanol (also known as grain alcohol) are being

marketed along with or instead of leaded or unleaded gasoline. For example, “E15” is a

gasohol comprised of 15% ethanol and 85% gasoline.

Do not use gasohol containing more than 15% ethanol, and do not use gasoline 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.

“E85” fuel is an alternative fuel comprised of 85 percent ethanol and 15 percent

gasoline, and is manufactured exclusively for use in Flexible Fuel Vehicles. “E85” is

not compatible with your vehicle. Use of “E85” may result in poor engine performance

and damage to your vehicle’s engine and fuel system. HYUNDAI recommends that

customers do not use fuel with an ethanol content exceeding 15 percent.

NOTICE

To prevent damage to your vehicle’s engine and fuel system:

śꢀ Never use gasohol which contains methanol.

śꢀ Never use gasohol containing more than 15% ethanol.

śꢀ Never use leaded fuel or leaded gasohol.

śꢀ Never use “E85” fuel.

Your New Vehicle Limited Warranty does not cover damage to the fuel system or any

performance problems caused by the use of “E85” fuel.

Foreword

Using Fuel Additives (except Detergent Fuel Additives)

Using fuel additives such as:

Silicone 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.

The Malfunction Indicator Lamp (MIL) may illuminate.

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.

Gasoline containing MMT

Some gasoline contains harmful manganese-based fuel additives such as MMT

(Methylcyclopentadienyl Manganese Tricarbonyl).

HYUNDAI does not recommend the use of gasoline containing MMT.

This type of fuel can reduce vehicle performance and affect your emission control

system.

The malfunction indicator lamp on the cluster may come on.

Detergent Fuel Additives

HYUNDAI recommends that you use good quality gasolines treated with detergent

additives such as TOP TIER Detergent Gasoline, which help prevent deposit formation

in the engine. These gasolines will help the engine run cleaner and enhance

performance of the Emission Control System. For more information on TOP TIER

Detergent Gasoline, please go to the website (www. toptiergas.com).

For customers who do not use TOP Tier Detergent Gasoline regularly, and have

problems starting or the engine does not run smoothly, detergent-based fuel additives

that you can purchase separately may be added to the gasoline. If TOP TIER Detergent

Gasoline is not available, one bottle of additive added to the fuel tank according to the

maintenance schedule is recommended (refer to the Maintenance Schedule in chapter

9).

Additives are available from your authorized HYUNDAI dealer 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:

śꢀ Observe all regulations regarding registration and insurance.

śꢀ Determine that acceptable fuel is available.
