Introduction
Your new vehicle is designed to use only
unleaded fuel having a pump octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
Gasoline containing alcohol andmethanolGasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
FUEL REQUIREMENTS
CAUTION
Never add any fuel system cleaning agents to the fuel tank other thanwhat has been specified. (Consult an authorized HYUNDAI dealer fordetails.)
WARNING
• Do not "top off" after the nozzle automatically shuts off when
refueling.
• Tighten the cap until it clicks, oth- erwise the Malfunction Indicator
Light “ ” will illuminate.
• Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.

Introduction4
1"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 10 percent.
Use of MTBEHYUNDAI recommends avoiding fuels
containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
Do not use methanolFuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.Gasolines for cleaner airTo help contribute to cleaner air,
HYUNDAI recommends that you use
gasolines treated with detergent addi-
tives, which help prevent deposit forma-
tion in the engine. These gasolines will
help the engine run cleaner and enhance
performance of the Emission Control
System.Operation in foreign countriesIf 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.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuel system and any performance prob-lems that are caused by the use of fuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)
CAUTION
Never use gasohol which containsmethanol. Discontinue use of any gasohol product which impairs dri-vability.
CAUTION
Your New Vehicle Limited Warrantydoes not cover damage to the fuelsystem or any performance prob- lems caused by the use of “E85” fuel.

Introduction
No special break-in period is needed. By
following a few simple precautions for the
first 600 miles (1,000 km) you may add to
the performance, economy and life of
your vehicle.
• 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 emergen- cies, to allow the brakes to seat prop-
erly.
• Don't let the engine idle longer than 3 minutes at one time.
• Don't tow a trailer during the first 1,200 miles (2,000 km) of operation.VEHICLE BREAK-IN PROCESS
CALIFORNIA PROPOSI-
TION 65 WARNING
Items contained in motor vehicles
or emitted from them are known to
the State of California to cause can-
cer and birth defects or reproduc-
tive harm. These include:
• Gasoline and its vapors
• Engine exhaust
• Used engine oil
• Interior passenger compartmentcomponents and materials
• Component parts which are sub- ject to heat and wear
In addition, battery posts, terminals
and related accessories contain
lead, lead compounds and other
chemicals known to the State of
California to cause cancer and
reproductive harm.

Introduction6
1This vehicle is equipped with an event
data recorder (EDR). The main pur-
pose of an EDR is to record, in certain
crash or near crash-like situations,
such as an air bag deployment or hit-
ting a road obstacle, data that will
assist in understanding how a vehi-
cle's systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety systems
for a short period of time, typically 30
seconds or less. The EDR in this vehi-
cle is designed to record such data
as:
* How various systems in your vehicle
were operating:
* Whether or not the driver and pas- senger safety belts were
buckled/fastened;
* How far (if at all) the driver was depressing the accelerator and/or
brake pedal; and,
* How fast the vehicle was traveling. These data can help provide a better
understanding of the circumstances
in which crashes and injuries occur.
NOTE: EDR data are recorded by your
vehicle only if a nontrivial crash situa-
tion occurs; no data are recorded by
the EDR under normal driving condi-
tions and no personal data (e.g.,
name, gender, age, and crash loca-
tion) are recorded. However, other
parties, such as law enforcement,
could combine the EDR data with the
type of personally identifying data
routinely acquired during a crash
investigation.
To read data recorded by an EDR, spe-
cial equipment is required, and
access to the vehicle or the EDR is
needed.
In addition to the vehicle manufacture,
other parties, such as law enforce-
ment, that have the special equip-
ment, can read the information if they
have access to the vehicle or the EDR.VEHICLE DATA COLLECTION AND EVENT DATA RECORDERS
