"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.Do not use methanol
Fuels 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.
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)For customers who do not use TOP Tier
Detergent Gasoline regularly, and have
problems starting or the engine does not
run smoothly, additives that you can buy
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is not
available, one bottle of additive added to
the fuel tank at every 7,500mile or every
engine oil change is recommended.
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.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuel
system and any performance prob-
lems that are caused by the use of
fuels containing methanol.
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.
CAUTION
Your New Vehicle Limited Warranty
does not cover damage to the fuel
system or any performance prob-
lems caused by the use of “E85” fuel.

Safety features of your vehicle
Seat belt restraint system
SEAT BELTS
WARNING
Seat belts are designed to bear
upon the bony structure of the
body, and should be worn low
across the front of the pelvis, chest
and shoulders, as applicable; wear-
ing the lap section of the belt
across the abdominal area must be
avoided.
Seat belts should be adjusted as
firmly as possible, consistent with
comfort, to provide the protection
for which they have been designed.
(Continued)
(Continued)
A slack belt will greatly reduce the
protection afforded to the occupant.
Care should be taken to avoid con-
tamination of the webbing with pol-
ishes, oils and chemicals and par-
ticularly battery acid. Cleaning may
safely be carried out using mild
soap and water. The belt should be
replaced if webbing becomes
frayed, contaminated or damaged.
It is essential to replace the entire
assembly after it has been worn in
a severe impact even if damage to
the assembly is not obvious. Belts
should not be worn with straps
twisted. Each seat belt assembly
must only be used by one occu-
pant; it is dangerous to put a belt
around a child being carried on the
occupant's lap.(Continued)
Avoid wearing twisted seat belts.
A twisted belt can't do its job as
well. In a collision, it could even
cut into you. Be sure the belt
webbing is straight and not twist-
ed.
Be careful not to damage the belt
webbing or hardware. If the belt
webbing or hardware is dam-
aged, replace it.
WARNING
For maximum restraint system
protection, the seat belts must
always be used whenever the car
is moving.
Seat belts are most effective
when seatbacks are in the
upright position.
Children age 12 and younger
must always be properly
restrained in the rear seat. Never
allow children to ride in the front
passenger seat. If a child over 12
must be seated in the front seat,
he/she must be properly belted
and the seat should be moved as
far back as possible.
Never wear the shoulder belt
under your arm or behind your
back. An improperly positioned
shoulder belt can cause serious
injuries in a crash. The shoulder
belt should be positioned midway
over your shoulder across your
collarbone.

Features of your vehicle
Turn signal indicator
The blinking arrows on the instrument
panel show the direction indicated by the
turn signals. If the arrow comes on but
does not blink, blinks more rapidly than
normal, or does not illuminate at all, a
malfunction in the turn signal system is
indicated. Your dealer should be consult-
ed for repairs.
High beam indicator
This indicator illuminates when the head-
lights are on and in the high beam posi-
tion or when the turn signal lever is pulled
into the Flash-to-Pass position.
Tail light indicator
This indicator illuminates when the tail
lights are on.
Engine oil pressure
warning light
This warning light indicates the engine oil
pressure is low.
If the warning light illuminates while driv-
ing:
1. Drive safely to the side of the road and
stop.
2. With the engine off, check the engine
oil level. If the level is low, add oil as
required.
If the warning light remains on after
adding oil or if oil is not available, call an
authorized HYUNDAI dealer.
CAUTION
If the engine is not stopped imme-
diately after the engine oil pressure
warning light is illuminated, severe
damage could result.
CAUTION
If the oil pressure warning light
stays on while the engine is run-
ning, serious engine damage may
result. The oil pressure warning
light comes on whenever there is
insufficient oil pressure. In normal
operation, it should come on when
the engine start/stop button is
turned on, then go out when the
engine is started. If the oil pressure
warning light stays on while the
engine is running, there is a serious
malfunction.
If this happens, stop the car as
soon as it is safe to do so, turn off
the engine and check the oil level. If
the oil level is low, fill the engine oil
to the proper level and start the
engine again. If the light stays on
with the engine running, turn the
engine off immediately. In any
instance where the oil light stays on
when the engine is running, the
engine should be checked by an
authorized HYUNDAI dealer before
the car is driven again.

Climate control air filter
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized HYUNDAI
dealer.
✽ ✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized HYUNDAI
dealer.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽ ✽
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor and
abnormal system operation may occur.OMG075033

WARNING- ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the win-
dows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxia-
tion.

The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the
exhaust system checked as soon as possible by an authorized HYUNDAI dealer.

Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the vehicle and back the car out.

If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield are
kept clear of snow, ice, leaves or other obstructions.

Driving your vehicle
Before entering vehicle
• Be sure that all windows, outside mir-
ror(s), and outside lights are clean.
Check the condition of the tires.
Check under the vehicle for any sign of
leaks.
Be sure there are no obstacles behind
you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in sec-
tion 7, “Maintenance”.
BEFORE DRIVING
CALIFORNIA PROPOSI-
TION 65 WARNING
Engine exhaust and a wide variety
of automobile components and
parts, including components found
in the interior furnishings in a vehi-
cle, contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of component
wear contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm.
WARNING
Driving while distracted can result
in a loss of vehicle control, that
may lead to an accident, severe
personal injury, and death. The dri-
ver’s primary responsibility is in
the safe and legal operation of a
vehicle, and use of any handheld
devices, other equipment, or vehi-
cle systems which take the driver’s
eyes, attention and focus away
from the safe operation of a vehicle
or which are not permissible by law
should never be used during oper-
ation of the vehicle.

Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽ ✽
NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.
Drive belt
A loose or damaged drive belt may result
in overheating of the engine.
WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
Driving on tires with no or insuffi-
cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
car. For further information and
tread limits, refer to “Tires and
wheels” in section 7.
