HomeLink®Wireless Control System
Your new mirror comes with an inte-
grated HomeLink Universal
Transceiver, which allows you to pro-
gram the mirror to activate your
garage door(s), estate gate, home
lighting, etc. The mirror actually
learns the codes from your various
existing transmitters.Retain the original transmitter for
future programming procedures (i.e.,
new vehicle purchase). It is also sug-
gested that upon the sale of the vehi-
cle, the programmed HomeLink but-
tons 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 posi-
tion 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 programmed to HomeLink for
quicker training and accurate trans-
mission of the radio-frequency.
Follow these steps to train your
HomeLink mirror:
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 pre-
vent potential harm or damage.
Do not use HomeLink with
any garage door opener that
lacks the safety stop and
reverse feature as required by
U.S. federal safety standards.
(This includes any garage
door opener model manufac-
tured before April 1, 1982.) A
garage door opener which
cannot detect an object, sig-
naling the door to stop and
reverse, does not meet cur-
rent U.S. federal safety stan-
dards. Using a garage door
opener without these features
increases risk of serious
injury or death. For more
details, call 1-800-355-3515 or
on the internet at www.home-
link.com.

ument.
Rolling code programming
To train a garage door opener (or
other rolling code equipped devices)
with the rolling code feature, follow
these instructions after completing
the "Programming" portion of this
text. (A second person may make the
following training procedures quicker
& easier.)

if this has not previously been
done. Refer to the "Programming"
portion of this text.
Operating HomeLink
To operate, simply press the pro-
grammed HomeLink button.
Activation will now occur for the
trained product (garage door, securi-
ty system, entry door lock, estate
gate, or home or office lighting). For
convenience, the hand-held trans-
mitter of the device may also be used
at any time. The HomeLink Wireless
Controls System (once programmed)
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
programming difficulties, contact
HomeLink at 1-800-355-3515 or on

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 innovative 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 following the out-
lined 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 suggested 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 operator, make
sure people and objects are out
of the way of the device to pre-
vent 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 standards
(this includes any garage door
opener model manufactured
before April 1, 1982). A garage
door that cannot detect an
object - signaling 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 it
clockwise until it "clicks" one time.
2. Close the fuel filler door until it is
latched securely.Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up 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 touch-
ing 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 lever to the P (Park)
position, set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.
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 noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.

Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter. Do not spill fuel on the exterior
surfaces of the vehicle. Any type
of fuel spilled on painted sur-
faces 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.
NOTICE
i
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.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.
