Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,
as well as minimize exhaust emissions and spark plug fouling.
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. 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.)
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 retailer of Genesis Branded products for additional
information.
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 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. Genesis Branded Vehicle 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:
• 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.
FUEL REQUIREMENTS

Introduction

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
or fuel additives 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).
Genesis Branded Vehicle 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
Genesis Branded Vehicle 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 at every 8,000
miles or 12 months is recommended.
Additives are available from your authorized retailer of Genesis Branded products
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.

VEHICLE MODIFICATIONS
• This vehicle should not be modified. Modification of your vehicle could affect its
performance, safety or durability and may even violate governmental safety and
emissions regulations.
• In addition, damage or performance problems resulting from any modification may
not be covered under warranty.
• If you use unauthorized electronic devices, it may cause the vehicle to operate
abnormally, wire damage, battery discharge and fire. For your safety, do not use
unauthorized electronic devices.
NOTICE
All warning sounds (e.g. welcome/good-bye sound, virtual engine sound) are
generated from the interior amplifiers. If necessary, we recommend you to purchase
Genesis Part to replace an interior amplifier. Any unauthorized product may cause a
malfunction of the interior amplifiers.
VEHICLE BREAK-IN PROCESS
• 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 emergencies, to allow the brakes to seat properly.
