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 mini-
mize exhaust emissions 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.
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
dealer for additional information.
Gasoline containing alcohol or
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol) are being marketed along with or
instead of leaded or unleaded gaso-
line.
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 problems and dam-
age to the fuel system.
Discontinue using gasohol of any
kind if drivability problems occur.
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. “E85” is not compati-
ble with your vehicle. Use of “E85”
may result in poor engine perform-
ance 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.
NOTICE
NOTICE
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.
CAUTION
•Do not "top off" after the noz-
zle automatically shuts off
when refueling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.

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 understanding how a vehicle's
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety sys-
tems for a short period of time,
typically 30 seconds or less. The
EDR in this vehicle is designed to
record such data as:
vehicle were operating;
passenger safety belts were
buckled/ fastened;
depressing the accelerator
and/or brake pedal; and,
ing. These data can help provide a bet-
ter understanding of the circum-
stances in which crashes and
injuries occur. NOTE: EDR data
are recorded by your vehicle only
if a non-trivial crash situation
occurs; no data are recorded by
the EDR under normal driving
conditions and no personal data
(e.g., name, gender, age, and
crash location) are recorded.
However, other parties, such as
law enforcement, could combine
the EDR data with the type of per-
sonally identifying data routinely
acquired during a crash investiga-
tion.
To read data recorded by an EDR,
special 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.

Safety system of your vehicle
• ALWAYS set up your mobile devices(i.e., MP3 players, phones, naviga-
tion units, etc.) when your vehicle is
parked or safely stopped.
ONLY use your mobile device when allowed by laws and when conditions
permit safe use. NEVER text or
email while driving. Most states have
laws prohibiting drivers from texting.
Some states and cities also prohibit
drivers from using handheld phones.
NEVER let the use of a mobile device distract you from driving. You
have a responsibility to your passen-
gers and others on the road to
always drive safely, with your hands
on the wheel as well as your eyes
and attention on the road.Control Your Speed
Excessive speed is a major factor in
crash injuries and deaths. Generally,
the higher the speed, the greater the
risk, but serious injuries can also
occur at lower speeds. Never drive
faster than is safe for current condi-
tions, regardless of the maximum
speed posted.
Keep Your Vehicle in Safe
Condition
Having a tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such prob-
lems, check your tire pressures and
condition frequently, and perform all
regularly scheduled maintenance.

Manual adjustment
Forward and rearward adjustment
To move the seat forward or rearward:
1. Pull up the seat slide adjustmentlever and hold it.
2. Slide the seat to the position you desire.
3. Release the lever and make sure the seat is locked in place. Move
forward and rearward without using
the lever. If the seat moves, it is not
locked properly.
Seatback angle
To recline the seatback:
1. Lean forward slightly and lift up theseatback lever.
2. Carefully lean back on the seat and adjust the seatback to the
position you desire.
3. Release the lever and make sure the seatback is locked in place.
(The lever MUST return to its orig-
inal position for the seatback to
lock.) Reclining seatback
Sitting in a reclined position when
the vehicle is in motion can be dan-
gerous. Even when buckled up, the
protection of your restraint system
(seat belts and air bags) is greatly
reduced by reclining your seatback.

OLF034003N
OLF034002N
NEVER ride with a reclined
seatback when the vehicle is
moving.
Riding with a reclined seatback
increases your chance of seri-
ous or fatal injuries in the event
of a collision or sudden stop.
Drivers and passengers should
ALWAYS sit well back in their
seats, properly belted, and with
the seatbacks upright.
