NOTICE indicates a situation which, if
not avoided, could result in vehicle
damage. Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions 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. (Do not use
methanol blended fuels)
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 HYUNDAI deal-
er for additional information.
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 exam-
ple, "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 prob-
lems and damage to the fuel system,
engine control system and emission con-
trol system.

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).
NOTICE
NOTICE

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).
Additives are available from your author-
ized HYUNDAI dealer along with infor-
mation on how to use them. Do not mix
other additives.
Operation in foreign countries
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
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.

Introduction
This vehicle is equipped with an event
data recorder (EDR). The main purpose
of an EDR is to record, in certain crash
or near crash-like situations, such as
an air bag deployment or hitting a road
obstacle, data that will assist in under-
standing how a vehicle’s systems per-
formed. 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 vehicle is designed to
record such data as:
were operating;
senger safety belts were buckled/
fastened;
depressing the accelerator and/or
brake pedal; and,
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 non-trivial crash situ-
ation 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
manufacturer, other parties, such as
law enforcement, that have the special
equipment, can read the information if
they have access to the vehicle or the
EDR.

Power adjustment (for driver's seat, if equipped)
The front seat can be adjusted by using
the control switches located on the out-
side of the seat cushion. Before driving,
adjust the seat to the proper position so
that you can easily control the steering
wheel, foot pedals and controls on the
instrument panel.
To prevent damage to the seats:
Always stop adjusting the seats
when the seat has been adjusted as
far forward or rearward as possible.
Do not adjust the seats longer than necessary when the engine is
turned off. This may result in unnec-
essary battery drain.
Do not operate two or more seats at the same time. This may result in an
electrical malfunction.
Forward and rearward adjustment
To move the seat forward or rearward:
1. Push the control switch forward or rearward.
2. Release the switch once the seat reaches the desired position.
Seatback angle
To adjust the seatback:
1. Rotate the top of control switch for-ward or rearward.
2. Release the switch once the seatback reaches the desired position.
NOTICE
NEVER allow children in the vehicle
unattended. The power seats are

shift lever is in P (Park), and the
parking brake is securely applied
whenever loading or unloading
cargo. Failure to take these steps
may allow the vehicle to move if the
shift lever is inadvertently moved to
another position.
