Immobilizer System
The immobilizer system helps protects
your vehicle from theft. If an improper-
ly coded key (or other device) is used,
the engine's fuel system is disabled.
When the Engine Start/Stop button is
placed in the ON position, the immo-
bilizer system indicator should come
on briefly, then go off. If the indicator
starts to blink, the system does not
recognize the coding of the key.
Place the Engine Start/Stop button to
the OFF position, then place the
Engine Start/Stop button to the ON
position again.
The system may not recognize your
key's coding if another immobilizer
key or other metal object (i.e., key
chain) is near the key. The vehicle
may not start because the metal may
interrupt the transponder signal from
transmitting normally.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.Do not attempt to alter this system or
add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
The transponder in your key is an
important part of the immobilizer
system. It is designed to give
years of trouble-free service, how-
ever you should avoid exposure to
moisture, static electricity and
rough handling. Immobilizer sys-
tem malfunction could occur.

Do not spill fuel on the exteriorsurfaces of the vehicle. Any type
of fuel spilled on painted sur-
faces may damage the paint.

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.

(Continued)
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 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.(Continued)
(Continued)
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
(Continued)
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 lever to the P (Park)
position, set the parking
brake, and place the Engine
Start/Stop button to the OFF
position. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.(Continued)
