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 when
refueling.
Tighten the cap until it clicks, oth-
erwise the " " light will illumi-
nate.
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.
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.
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)
Do not get back into a vehicle
once 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 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 with the vehi-
cle should be maintained until
the filling is complete.
(Continued)

Features of your vehicle22 4(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 by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler 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.
(Continued)
(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 or 911. Follow any safety
instructions they provide.
CAUTION
Make sure to refuel with unleaded
fuel only.
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.
(Continued)
(Continued)
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 lid will not open in
cold weather because the area
around it is frozen, push or lightly
tap the lid.
After refueling, make sure the fuel
cap is installed securely to pre-
vent fuel spillage in the event of
an accident.

Retain the original transmitter for future
programming procedures (i.e., new vehi-
cle purchase). It is also suggested that
upon the sale of the vehicle, the pro-
grammed HomeLink buttons be erased
for security purposes (follow step 1 in the
“Programming” portion of this text).
Programming
Your vehicle may require the ignition
switch to be turned to the ACC position
for programming and/or operation of
HomeLink. It is also recommended that a
new battery be replaced in the hand-held
transmitter of the device being pro-
grammed to HomeLink for quicker train-
ing and accurate transmission of the
radio-frequency.
Follow these steps to train your
HomeLink mirror:1. When programming the buttons for the
first time, press and hold
the left and
center buttons (
,
)simultane-
ously until the indicator light begins to
flash after approximately 20 seconds.
(This procedure erases the factory-set
default codes. Do not perform this step
to program additional hand-held trans-
mitters.)
WARNING
When programming the
HomeLink® Wireless Control
System, you may be operating a
garage door or gate operator.
Make sure that people and objects
are out of the way of the moving
door or gate to prevent potential
harm or damage.
Do not use HomeLink with any
garage door opener that lacks the
safety stop and reverse feature
as required by federal safety
standards. (This includes any
garage door opener model manu-
factured before April 1, 1982.) A
garage door opener which cannot
detect an object, signaling the
door to stop and reverse, does
not meet current federal safety
standards. Using a garage door
opener without these features
increases risk of serious injury or
death. For more information, call
1-800-355-3515 or on the internet
at www.homelink.com.

Features of your vehicle34 4Operating HomeLink
To operate, simply press the pro-
grammed HomeLink button. Activation
will now occur for the trained product
(garage door, security system, entry door
lock, estate gate, or home or office light-
ing). For convenience, the hand-held
transmitter of the device may also be
used at any time. The HomeLink
Wireless Controls System (once pro-
grammed) or the original hand-held
transmitter may be used to activate the
device (e.g. garage door, entry door lock,
etc.). In the event that there are still pro-
gramming difficulties, contact HomeLink
at 1-800-355-3515 or on the internet at
www.homelink.com.Erasing programmed HomeLink but-
tons
To erase the three programmed buttons
(individual buttons cannot be erased):
Press and hold the left and center
buttons simultaneously, until the indi-
cator light begins to flash (approxi-
mately 20 seconds). Release both but-
tons. Do not hold for longer than 30
seconds.
HomeLink is now in the train (or learning)
mode and can be programmed at any
time.Reprogramming a single HomeLink
button
To program a device to HomeLink using
a HomeLink button previously trained,
follow these steps:
1. Press and hold the desired HomeLink
button. Do NOT release until step 4
has been completed.
2. When the indicator light begins to flash
slowly (after 20 seconds), position the
hand-held transmitter 1 to 3 inches
away from the HomeLink surface.
3. Press and hold the hand-held trans-
mitter button (or press and “cycle” - as
described in “Canadian Programming”
above).
4. The HomeLink indicator light will flash,
first slowly and then rapidly. When the
indicator light begins to flash rapidly,
release both buttons.
The previous device has now been
erased and the new device can be acti-
vated by pushing the HomeLink button
that has just been programmed. This pro-
cedure will not affect any other pro-
grammed HomeLink buttons.

emission control system components. If
this light illuminates while driving, it indi-
cates that a potential problem has been
detected somewhere in the emission
control system.
This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
while driving, or does not illuminate when
the ignition key is turned to the ON posi-
tion, take your vehicle to your nearest
authorized Hyundai dealer and have the
system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorized Hyundai dealer promptly.

warning indicatorThis warning light indicates the washer
fluid reservoir is near empty. Refill the
washer fluid as soon as possible.
CAUTION
Prolonged driving with the
Emission Control System
Malfunction Indicator Light

converter damage is possible
which could result in loss of
engine power. Have the Engine
Control System inspected as soon
as possible by an authorized
Hyundai dealer.
