HOW TO USE THIS MANUAL

1-5
01
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 95) 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.
