ensure the following:
- Any tools or other loose objects are removed from the engine room area
or hood opening area
- All glove, rags, or other combustible material is removed from the engine
compartment

- All filler caps are tightly and
correctly installed
2. Lower the hood halfway (lifted approximately 12 inches (30 cm) from
the closed position) and push down
to securely lock in place. Then double
check to be sure the hood is secure.
If the hood can be raised slightly, it is
not securely locked. Open it again and
close it with more force.

all obstructions are removed from
around the hood opening.
• Always double check to be sure that
the hood is firmly latched before
driving away. Check there is no
hood open warning light or message
displayed on the instrument cluster.
Driving with the hood opened may
cause a total loss of visibility, which
might result in an accident.
• Do not move the vehicle with the
hood in the raised position, as vision
is obstructed, which might result in
an accident, and the hood could fall
or be damaged.

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 deicer fluid (do not use

WARNING
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 nozzle, you
should eliminate the potential 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.
• Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cellular
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 buildup 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
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. 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 button to the P (Park) position,
set the parking brake, and place
the ignition switch to the LOCK/
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.
• Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.• If a fire breaks out during refueling,
leave the vicinity of the vehicle, and
immediately contact 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 completely removing the cap.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
Information
Make sure to refuel your vehicle according
to the “Fuel Requirements” suggested in
the Introduction chapter.
NOTICE
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces 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.
