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.
Discontinue using gasohol of any kind if
drivability problems occur.
NOTICE
NOTICE
CAUTION indicates a hazardous sit-
uation which, if not avoided, could

Fuel Filler Door
Opening the fuel filler door
The fuel filler door must be opened from
inside the vehicle by pulling up the fuel
filler door release lever.
1. Turn the engine off. Locate the fuel filler door release lever on the floor on
the left side of the driver seat.
2. Pull up on the release lever. 3. Pull the fuel filler door (1) out to fully
open.
4. To remove the fuel tank cap (2), turn it counterclockwise. You may hear a
hissing noise as the pressure inside
the tank equalizes.
5. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open because
ice has formed around it, tap lightly or
push on the door to break the ice and
release the door. Do not pry on the door. If
necessary, spray around the door with an
approved de-icer fluid (do not use radiator
anti-freeze) or move the vehicle to a warm
place and allow the ice to melt.

Closing the fuel filler door
1. To install the fuel tank cap, turn itclockwise until it "clicks" one time.
2. Close the fuel filler door until it is latched securely.
Gasoline is highly flammable and
explosive. Failure to follow these
guidelines may result in SERIOUS
INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refueling, note the loca-
tion of the Emergency Gasoline
Shut-Off, if available, at the gas
station.
Before touching the fuel nozzle,
you should eliminate the poten-
tial build-up of static electricity
by touching a metal part of the
vehicle, a safe distance away
from the fuel filler neck, nozzle, or
other gas source, with your bare
hand. (Continued)
WARNING
(Continued)
Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors and cause a
fire.
Do not get back into a vehicle
once you have begun refueling.
You can generate a build-up of
static electricity by touching, rub-
bing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source, with your bare hand.
When using an approved
portable fuel container, be sure to
place the container on the
ground prior to refueling. Static
electricity discharge from the
container can ignite fuel vapors
causing a fire.(Continued)
(Continued)Once refueling has begun, con-
tact between your bare hand and
the vehicle should be maintained
until the filling is complete.
Use only approved portable plastic
fuel containers designed to carry
and store gasoline.
When refueling, always move the
shift lever to the P (Park) posi-
tion, set the parking brake, and
place the ignition switch to the
LOCK/OFF position. Sparks pro-
duced by electrical components
related to the engine can ignite
fuel vapors causing a fire.
Do not use matches or a lighter
and do not smoke or leave a lit
cigarette in your vehicle while at
a gas station, especially during
refueling.
Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage. (Continued)

Information
Make sure to refuel your vehicle according
to the "Fuel Requirements" suggested in
the Introduction chapter. Do not spill fuel on the exterior sur-
faces of the vehicle. Any type of fuel
spilled on painted surfaces may
damage the paint.
If the fuel filler cap requires replace- ment, use only a genuine HYUNDAI
cap or the equivalent specified for
your vehicle. An incorrect fuel filler
cap can result in a serious malfunc-
tion of the fuel system or emission
control system.
NOTICE
i
(Continued)
If a fire breaks out during refuel-
ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment. Follow any safety instruc-
tions they provide.
If pressurized fuel sprays out, it
can cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.

Convenient features of your vehicle
If the gauge pointer moves beyond the
normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the Engine
Overheats" in chapter 6.
Fuel gauge
This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Information
• The fuel tank capacity is given in chap-ter 8.
• The fuel gauge is supplemented by a low fuel warning light, which will illuminate
when the fuel tank is nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.
NOTICE
iNOTICE
Running out of fuel can expose
vehicle occupants to danger. You
must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
"E (Empty)" level.
WARNINGNever remove the radiator cap or
reservoir cap when the engine is
hot. The engine coolant is under
pressure and could severely burn.
Wait until the engine is cool before
adding coolant to the reservoir.

Certification label
The certification label is located on
the driver’s door sill at the center pil-
lar and shows the maximum allow-
able weight of the fully loaded vehi-
cle. This is called the GVWR (Gross
Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all
occupants, fuel and cargo.
This label also tells you the maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating (GAWR).The total weight of the vehicle,
including all occupants, accessories,
cargo, and trailer tongue load must
not exceed the Gross Vehicle Weight
Rating (GVWR) or the Gross Axle
Weight Rating (GAWR). To find out
the actual loads on your front and
rear axles, you need to go to a weigh
station and weigh your vehicle. Be
sure to spread out your load equally
on both sides of the centerline.
Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
NOTICE
If you carry items inside your
vehicle (e.g., suitcases, tools,
packages, or anything else),
they are moving as fast as the
vehicle. If you have to stop or
turn quickly, or if there is a
crash, the items will keep going
and can cause an injury if they
strike the driver or a passenger.

Put items in the cargo area of
your vehicle. Try to spread the
weight evenly.
Do not stack items, like suit-
cases, inside the vehicle
above the tops of the seats.
Do not leave an unsecured
child restraint in your vehicle.
When you carry something
inside the vehicle, secure it.
WARNING
OBH059070
Overloading
Never exceed the GVWR for
your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
affect your vehicle's handling
and braking ability, and cause
an accident.
Do not overload your vehicle.
Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible
tire failure, increased stop-
ping distances and poor vehi-
cle handling-all of which may
result in a crash.
