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 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:
• 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.
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).
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.
