WARNING
- Refueling
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.
Do not "top off" after the nozzle automatically shuts off whenrefueling.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-dent.

(Continued)
Do not get back into a vehicleonce you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. 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.
When using an approved portable fuel container, be sure toplace 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 with the vehicleshould be maintained until the
filling is complete.
(Continued)WARNING - Refueling dan-
gers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines care-
fully. Failure to follow these guide-
lines may result in severe personal
injury, severe burns or death by fire
or explosion.
Read and follow all warning at the gas station facility.
Before refueling note the location of the Emergency Gasoline Shut-
Off, if available, at the gas station
facility.
Before touching the fuel nozzle, you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas source.
(Continued)(Continued)Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
Do not use cellular phones while refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
When refueling, always shut the engine off. Sparks produced byelectrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure thefiller cap and filler door are
securely closed, before starting
the engine.
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. Automotive fuel is
highly flammable and can, when
ignited, result in fire.

This warning light will illuminate for
approximately 6 seconds each time you
turn the engine start/stop button to theON position. This light also comes on when the

warning light does not come on, or
continuously remains on after operating
for about 6 seconds when you turn the
engine start/stop button to the ON posi-
tion or start the engine, or if it comes on
while driving, have the SRS inspected by
an authorized HYUNDAI dealer.
Anti-lock brake system(ABS) warning light

start/stop button is turned ON and goes
off in approximately 3 seconds if the sys-
tem is operating normally.
If the ABS warning light remains on,
comes on while driving, or does not
come on when the engine start/stop but-
ton is turned to the ON position, this indi-
cates that the ABS may have malfuc-tioned.
If this occurs, have your vehicle checked
by an authorized HYUNDAI dealer as
soon as possible. The normal braking
system will still be operational, but with-
out the assistance of the anti-lock brakesystem.

nal system. You should consult your deal-
er for repairs.

WARNING
If the both ABS and brake warning
lights are on and stay on, your vehi-
cle’s brake system will not work
normally during sudden braking. In
this case, avoid high speed driving
and abrupt braking. Have your vehi-
cle checked by an authorized
HYUNDAI dealer as soon as possi-
ble.
