FUEL REQUIREMENTS
F7
Introduction
Your new vehicle is designed to obtain maximum performance with UNLEAD-
ED FUEL, as well as minimize exhaust emissions and spark plug fouling.
Your new vehicle is designed to use only unleaded fuel having an octane num-
ber ((R+M)/2) of 87 (Research Octane Number 91) or higher. For improved
vehicle performance, premium unleaded fuel with an octane number ((R+M)/2)
of 91 (Research Octane Number 96) or higher is recommended. (Do not use
methanol blended fuels.)
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 retailer of Genesis Branded products for addi-
tional information.
NOTICE
• Do not "top off" after the nozzle automatically shuts off when refu-
eling.
• Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an accident.
WARNING

Introduction
F8
Gasoline containing alcohol or 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 gaso-
line or gasohol containing any methanol. Either of these fuels may cause dri-
vability 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 per-
cent 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 sys-
tem. Genesis Branded Vehicle recommends that customers do not use fuel
with an ethanol content exceeding 15 percent.
To prevent damage to your vehicle’s engine and fuel system:
• Never use gasohol which contains methanol.
• Never use gasohol containing more than 15% ethanol.
• Never use leaded fuel or leaded gasohol.
• 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.
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.
Damage to the fuel system or performance problem caused by the use
of these fuels or fuel additives may not be covered by your New Vehicle
Limited Warranty.
NOTICE
NOTICE

Gasoline containing MMT
Some gasoline contains harmful manganese-based fuel additives such as
MMT (Methylcyclopentadienyl Manganese Tricarbonyl).
Genesis Branded Vehicle does not recommend the use of gasoline contain-
ing 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
Genesis Branded Vehicle recommends that you use good quality gasolines treat-
ed 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 at every 7,500 miles or 12 months is recommended.
Additives are available from your authorized retailer of Genesis Branded prod-
ucts 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:
• Observe all regulations regarding registration and insurance.
• Determine that acceptable fuel is available.
