Introduction
"E85" fuel is an alternative fuel com-
prised 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 system.
HYUNDAI 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 containsmethanol.
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 accel-
eration, 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 pow-
ertrain.
- The Malfunction Indicator Lamp (MIL)
may illuminate.
Damage to the fuel system or per-
formance 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 man-
ganese-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 per-
formance and affect your emission con-
trol system.
The malfunction indicator lamp on the
cluster may come on.
Detergent Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help prevent
deposit formation in the engine. These
gasolines will help the engine run clean-
er and enhance performance of the
Emission Control System. For more infor-
mation on TOP TIER Detergent
Gasoline, please go to the website
(www
.toptiergas.com).

Introduction
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 addi-
tives 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 7).

If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg-istration and insurance.
Determine that acceptable fuel is avail- able. This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or dura-
bility and may even violate governmen-
tal safety and emissions regulations.
In addition, damage or performance
problems resulting from any modifica-
tion may not be covered under warran-
ty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge and fire. For your safety,
do not use unauthoriz ed electronic
devices. By following a few simple precautions for
the first 600 miles (1,000 km) you may
add to the performance, economy and

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.
