Introduction
"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.
To prevent damage to your vehicle’s
engine and fuel system:
Never use gasohol which con- tains methanol.
Never use gasohol containing more than 10% 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 perform-
ance problems caused by the use
of "E85" fuel.
Other fuels
Using fuels such as;
- Silicone (Si) contained fuel,
- Ferrocene (Fe) contained fuel, and
- Other metallic additives contained fuels,
may cause damage to the engine by
plugging, misfiring, poor accelera-
tion, engine stalling, catalyst melting,
abnormal corrosion, life cycle reduc-
tion.
- The Malfunction Indicator Lamp (MIL) may illuminate.
Damage to the fuel system or per-
formance problem caused by the
use of these fuels may not be cov-
ered by your New Vehicle Limited
Warranty.
Gasoline containing MMT
Some gasoline contains harmful
manganese-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
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with
detergent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance performance
of the Emission Control System. For
more information on TOP TIER
Detergent Gasoline, please go to the
website (www
.toptiergas.com).

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.

Front Seats
Take the following precautions
when adjusting your seat belt:
NEVER use one seat belt for
more than one occupant.
Always position the seatback
upright with the lap portion of
the seat belt snug and low
across the hips.
NEVER allow children or small
infants to ride in a passenger’s
lap.
Do not route the seat belt
across your neck, across sharp
edges, or reroute the shoulder
strap away from your body.
Do not allow the seat belt to
become caught or jammed.
WARNING
Take the following precautions
when adjusting your seat:
NEVER attempt to adjust the
seat while the vehicle is mov-
ing. The seat could respond
with unexpected movement
and may cause loss of vehicle
control resulting in an acci-
dent.
Do not place anything under
the front seats. Loose objects
in the driver's foot area could
interfere with the operation of
the foot pedals, causing an
accident.
Do not allow anything to inter-
fere with the normal position
and proper locking of the seat-
back.
Do not place a cigarette lighter
on the floor or seat. When you
operate the seat, gas may exit
out of the lighter causing a fire.(Continued)
WARNING
To prevent injury:
Do not adjust your seat while
wearing your seat belt.
Moving the seat cushion for-
ward may cause strong pres-
sure on your abdomen.
Do not allow your hands or
fingers to get caught in the
seat mechanisms while the
seat is moving.
CAUTION
(Continued)
Use extreme caution when
picking small objects trapped
under the seats or between
the seat and the center con-
sole. Your hands might be cut
or injured by the sharp edges
of the seat mechanism.

The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:
1. SRS air bag warning light
2. Retractor pre-tensioner
3. SRS control module
4. Anchor Pre-tensionerThe sensor that activates the SRS
air bag is connected with the
pre–tensioner seat belts. The SRS
air bag warning light on the instru-
ment panel will illuminate for
approximately 6 seconds after the
ignition switch is in the ON posi-
tion, and then it should turn off.
If the pre-tensioner is not working
properly, the warning light will illu-
minate even if the SRS air bag is
not malfunctioning. If the warning
light does not illuminate, stays
illuminated or illuminates when
the vehicle is being driven, have
an authorized HYUNDAI dealer
inspect the pre-tensioner seat
belts and SRS air bags as soon as
possible.
Both the driver's and front pas-
senger's pre-tensioner seat
belts may be activated in certain
frontal or side collisions or
rollovers.
The pre-tensioners will not be activated if the seat belts are not
worn at the time of the collision.
When the pre-tensioner seat belts are activated, a loud noise
may be heard and fine dust,
which may appear to be smoke,
may be visible in the passenger
compartment. These are normal
operating conditions and are not
hazardous.
Although it is non-toxic, the fine dust may cause skin irritation
and should not be breathed for
prolonged periods. Wash all
exposed skin areas thoroughly
after an accident in which the
pre-tensioner seat belts were
activated.

Securing a child restraint witha lap belt or lap/shoulder belt
When not using the LATCH system,
all child restraints must be secured to
a vehicle rear seat with the lap part
of a lap/shoulder belt.
Automatic locking mode
Since all passenger seat belts move
freely under normal conditions and
only lock under extreme or emer-
gency conditions (emergency locking
mode), you must manually pull the
seat belt all the way out to shift the
retractor to the "Automatic Locking"
mode to secure a child restraint.
The "Automatic Locking" mode will
help prevent the normal movement
of the child in the vehicle from caus-
ing the seat belt to loosen and com-
promise the child restraint system. To
secure a child restraint system, use
the following procedure. To install a child restraint system on
the rear seats, do the following:
1. Place the child restraint system on
a rear seat and route the lap/
shoulder belt around or through
the child restraint, following the
restraint manufacturer's instruc-
tions.
Be sure the seat belt webbing is
not twisted.
When using the rear center seat
belt, you should also refer to the
"3-point Rear Center Seat Belt"
section in this chapter.
NOTICE
ALWAYS place a rear-facing
child restraint in the rear seat of
the vehicle.
Placing a rear-facing child
restraint in the front seat can
result in serious injury or death
if the child restraint is struck by
an inflating air bag.
WARNING

5. Remove as much slack from the belt as possible by pushing down
on the child restraint system while
feeding the shoulder belt back into
the retractor.
6. Push and pull on the child restraint system to confirm that the seat
belt is holding it firmly in place. If it
is not, release the seat belt and
repeat steps 2 through 6.
7. Double check that the retractor is in the "Automatic Locking" mode
by attempting to pull more of the
seat belt out of the retractor. If you
cannot, the retractor is in the
"Automatic Locking" mode.
If your CRS manufacturer instructs or
recommends you to use a tether
anchor with the lap/shoulder belt,
refer to the previous pages for more
information. When the seat belt is allowed to
retract to its fully stowed position,
the retractor will automatically
switch from the "Automatic
Locking" mode to the emergency
lock mode for normal adult usage.
To remove the child restraint, press
the release button on the buckle and
then pull the lap/shoulder belt out of
the restraint and allow the seat belt
to retract fully.
NOTICE
If the retractor is not in the
"Automatic Locking" mode, the
child restraint can move when
your vehicle turns or stops sud-
denly. A child can be seriously
injured or killed if the child
restraint is not properly
anchored in the car, including
manually pulling the seat belt
all the way out to shift the rec-
tractor to the "Automatic
Locking" mode.

After an air bag inflates, take
the following precautions:
Open your windows and doors
as soon as possible after
impact to reduce prolonged
exposure to the smoke and
powder released by the inflat-
ing air bag.
Do not touch the air bag stor-
age area’s internal compo-
nents immediately after an air
bag has inflated. The parts
that come into contact with an
inflating air bag may be very
hot.(Continued)
WARNING
What to Expect After an Air
Bag Inflates
After a frontal or side air bag inflates,
it will deflate very quickly. Air bag
inflation will not prevent the driver
from seeing out of the windshield or
being able to steer. Curtain air bags
may remain partially inflated for
some time after they deploy.
Noise and smoke from inflatingair bag
When the air bags inflate, they make
a loud noise and may produce
smoke and powder in the air inside of
the vehicle. This is normal and is a
result of the ignition of the air bag
inflator. After the air bag inflates, you
may feel substantial discomfort in
breathing because of the contact of
your chest with both the seat belt and
the air bag, as well as from breathing
the smoke and powder. The powder
may aggravate asthma for some
people. If you experience breathing
problems after an air bag deploy-
ment, seek medical attention imme-
diately.
Though the smoke and powder are
nontoxic, they may cause irritation to
the skin, eyes, nose, throat, etc. If
this is the case, wash and rinse with
cold water immediately and seek
medical attention if the symptoms
persist.
(Continued)Always wash exposed skin
areas thoroughly with cold
water and mild soap.
Always have an authorized
HYUNDAI dealer replace the air
bag immediately after deploy-
ment. Air bags are designed to
be used only once.
