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. (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 thanwhat 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 orinstead of leaded or unleaded gaso-
line. For example, "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 problems and dam-age to the fuel system, engine controlsystem and emission control system.
Discontinue using gasohol of any
kind if drivability problems occur.
NOTICE
NOTICE
CAUTION indicates a hazardous
situation which, if not avoided,could result in minor or moder-
ate injury.
CAUTION

3. Pull the fuel filler door (1) outwardto access the fuel tank cap.
4. To remove the fuel tank cap (2), turn it counterclockwise. You may hear a hissing noise as the pres-
sure 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.

Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by
touching, rubbing 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 discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,nozzle or other gasoline
source, with your bare hand.
When using an approved
portable fuel container, besure 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,
contact between your bare
hand and the vehicle shouldbe 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)
position, set the parking
brake, and place engine Start/
Stop button to the OFF posi-
tion. Sparks produced byelectrical components relatedto 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)
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
location of the Emergency
Gasoline Shut-Off, if available,at the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.

faces may damage the paint.
If the fuel filler cap requires replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. Anincorrect fuel filler cap canresult in a serious malfunctionof the fuel system or emission
control system.Emergency fuel filler door

(Continued)
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gasstation and then contact the
local fire department. Follow
any safety instructions 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 pre-
vent fuel spillage in the eventof an accident.

Add fuel into the fuel tank
within 20 minutes after open-
ing the fuel filler door. After 20
minutes, the fuel tank may
shut off, causing fuel to over-
flow. In this case, re-press the
fuel filler door opening but-ton.
Do not leave the fuel filler
door opened for an extended
period of time. It may dis-
charge the battery.
Close the fuel filler door after
fueling the vehicle. If you start
the vehicle with the fuel filler
door opened, the message,
"Check fuel lid," illuminates
on the LCD display.
Avoid refueling the vehicle
while charging the (high-volt-
age) hybrid battery. It may
cause a fire or an explosion
due to static electricity.
