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).

Information
Make sure to refuel your vehicle according
to the "Fuel Requirements" suggested in
the Introduction chapter. Do not spill fuel on the exterior sur-
faces of the vehicle. Any type of fuel
spilled on painted surfaces may
damage the paint.
If the fuel filler cap requires replace- ment, use only a genuine HYUNDAI
cap or the equivalent specified for
your vehicle. An incorrect fuel filler
cap can result in a serious malfunc-
tion of the fuel system or emission
control system.
NOTICE
i
(Continued)
If a fire breaks out during refuel-
ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment. Follow any safety instruc-
tions they provide.
If pressurized fuel sprays out, it
can cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.

If the gauge pointer moves beyond the
normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the Engine
Overheats" in chapter 6.
Fuel gauge
This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Information
• The fuel tank capacity is given in chap-ter 8.
• The fuel gauge is supplemented by a low fuel warning light, which will illuminate
when the fuel tank is nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.
NOTICE
iNOTICE
Running out of fuel can expose
vehicle occupants to danger. You
must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
"E (Empty)" level.
WARNINGNever remove the radiator cap or
reservoir cap when the engine is
hot. The engine coolant is under
pressure and could severely burn.
Wait until the engine is cool before
adding coolant to the reservoir.

Range
Range (1)
The range is the estimated distancethe vehicle can be driven with the
remaining fuel in the fuel tank.
- Distance range:1 ~ 9999 mi. or 1 ~ 9999 km
If the estimated distance is below 1 mile (1 km), the trip computer will dis-
play "----" as the range.
Information
• If the vehicle is not on level ground orthe battery power has been interrupted,
the range function may not operate cor-
rectly.
(Continued)(Continued)
• The range may differ from the actual
driving distance as it is an estimate of
the available driving distance.
• The trip computer may not register additional fuel if less than 1 gallon (3
liters) of fuel are added to the vehicle.
• The fuel economy and range may vary significantly based on driving condi-
tions, driving habits, and condition of
the vehicle.
Average Fuel Economy (2)
The average fuel economy is calculat-ed by the total driving distance and fuel
consumption since the last average
fuel economy reset.

The average fuel economy can be reset both manually and automatically.
Manual reset
To clear the average fuel economy man-
ually, press the OK button on the steering
wheel for more than 1 second when the
average fuel economy is displayed.
For more information on the OK but-

in this chapter. Automatic reset
To reset the average fuel economy auto-
matically whenever refueling, select the
"After refueling" mode in User Setting
menu of the LCD display (
Refer to "LCD
Display").
Under "After refueling" mode, the aver-
age fuel economy will be cleared to zero
(----) when the vehicle speed exceeds 1
mph (1 km/h) after refueling more than
1~2 gallons (3~6 liters).
