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

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, engine con-
trol system and emission control sys-
tem.
Discontinue using gasohol of any
kind if drivability problems occur.

Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise 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
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.

WARNING
(Continued)
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.
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by touch-
ing, 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 danger-
ous static electricity discharge
by touching 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, be
sure to place the container on
the ground prior to refueling.
(Continued)
(Continued)
Static electricity discharge
from the container can ignite
fuel vapors causing a fire.
Once refueling has begun,
contact 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)
position, set the parking brake,
and place engine Start/Stop
button to the OFF position.
Sparks produced 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.

Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exterior
surfaces of the vehicle. Any type
of fuel spilled on painted sur-
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. An
incorrect fuel filler cap can
result in a serious malfunction
of the fuel system or emission
control system.
Emergency fuel filler door

If the fuel filler door does not open
using the remote fuel filler door
release button, you can open it man-
ually. Pull the handle of the release
located on the left side of the lug-
gage compartment outward slightly.
NOTICE
i(Continued)
Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station 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 prevent
fuel spillage in the event of an
accident.
