Control System
The HomeLink®Wireless Control
System can replace up to three hand-
held radio-frequency (RF) transmitters
with a single built-in device. This innova-
tive feature will learn the radio frequency
codes of most current transmitters to
operate devices such as gate operators,
garage door openers, entry door locks,
security systems, even home lighting.
Both standard and rolling code-equipped
transmitters can be programmed by fol-
lowing the outlined procedures.
Additional HomeLink
®information can
be found at: www.homelink.com or by
calling 1-800-355-3515.
Retain the original transmitter of the RF
device you are programming for use in
other vehicles as well as for future
HomeLink
®programming. It is also sug-
gested that upon the sale of the vehicle,
the programmed HomeLink
®buttons be
erased for security purposes.
Before programming HomeLink®to
a garage door opener or gate oper-
ator, make sure people and objects
are out of the way of the device to
prevent potential harm or damage.
Do not use the HomeLink
®with any
garage door opener that lacks the
safety stop and reverse features
required by U.S. federal safety stan-
dards (this includes any garage
door opener model manufactured
before April 1, 1982). A garage door
that cannot detect an object - sig-
naling the door to stop and reverse
- does not meet current U.S. federal
safety standards. Using a garage
door opener without these features
increases the risk of serious injury
or death.

Closing the fuel filler door
1. To install the fuel tank cap, turn itclockwise 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 loca-
tion of the Emergency Gasoline
Shut-Off, if available, at the gas
station.
Before touching the fuel nozzle,
you should eliminate the poten-
tial 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. (Continued)
WARNING
(Continued)
Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cel-
lular 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 build-up of
static electricity by touching, rub-
bing 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 dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line 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.(Continued)
(Continued)Once refueling has begun, con-
tact 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) posi-
tion, set the parking brake, and
place the ignition switch to the
LOCK/OFF position. Sparks pro-
duced 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. (Continued)

Information
Make sure to refuel your vehicle according
to the "Fuel Requirements" suggested in
the Introduction chapter. Do not spill fuel on the exterior sur-
faces of the vehicle. Any type of fuel
spilled on painted surfaces may
damage the paint.
If the fuel filler cap requires replace- ment, use only a genuine HYUNDAI
cap or the equivalent specified for
your vehicle. An incorrect fuel filler
cap can result in a serious malfunc-
tion of the fuel system or emission
control system.
NOTICE
i
(Continued)
If a fire breaks out during refuel-
ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment. Follow any safety instruc-
tions 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 acci-
dent.
