The airbag modules are located both in the
center of the steering wheel and in the front
passenger's panel above the glove box.
When the SRSCM detects a considerable im-
pact to the front of the vehicle, it will automatically
deploy the airbags.
Upon deployment, tear seams molded directly
into the pad covers will separate under pres-
sure from the expansion of the airbags. Further
opening of the covers then allows full inflation of
the airbags.
A fully inflated airbag in combination with a
properly worn seat belt slows the driver's or the
passenger's forward motion, thus reducing the
risk of head or chest injury.
After complete inflation, the airbag immediately
starts deflating, enabling the driver to maintain
forward visibility.
CAUTION:When installing the container of liquid air
freshener inside a vehicle, do not place it
near the instrument cluster nor on the in-
strument panel pad surface. If there is any
leakage from the air freshener onto these
areas (Instrument cluster, instrument panel
pad or air ventilator), it may damage these
parts. If the liquid from the air freshener
does leak onto these areas, wash them with
water immediately.
WARNING:o When the SRS is activated, there may be
a loud noise and fine dust will be re-
leased throughout the vehicle. These
conditions are normal and are not haz-
ardous. However, the fine dust gener-
ated during airbag deployment may
cause skin irritation. Be sure to wash
your hands and face thoroughly with
lukewarm water and a mild soap after an
accident in which the airbags were de-
ployed.
o The SRS can function only when the
ignition key is in the "ON" position. If the
SRS SRI does not come on, or continu-
ously remains on, after flashing for about
6 seconds when the ignition key is
turned to the "ON" position, or after the
engine is started, or comes on while
driving, the SRS is not working properly.
If this occurs, have your vehicle immedi-
ately inspected by your Hyundai dealer.
o Before you replace a fuse or disconnect
a battery terminal, turn the ignition key
to the "LOCK" position or remove the
ignition key. Never remove or replace the
air bag related fuse(s) when the ignition
key is in the "ON" position. Failure to
heed this warning will cause the SRS SRI
to illuminate.

Programming
Your vehicle may require that the ignition switch
to be turned to the "ACC" position to program
and/or operate HomeLink system. It is also
recommended that a new battery be placed in
the handheld transmitter of the device being
programmed to HomeLink for quicker program-
ming and accurate transmission of the radio-
frequency.
Follow these steps to program your HomeLink
mirror:
1. When programming the buttons for the first
time, press and hold the two outside
HomeLink buttons ( , ), releasing when
the indicator light begins to flash (approxi-
mately 20 seconds). This procedure erases
the factory-set default codes. Do not per-
form this step when programming additional
transmitters.2. Hold the transmitter of the device you want
to program 1 to 3 inches away from the
bottom of the mirror. Simultaneously press
the handheld transmitter button and the
HomeLink button you wish to program. The
indicator light will flash slowly at first, then
rapidly, indicating successful programming.
3. If the garage door opener or other device you
wish to program is rolling-code equipped,
proceed to the "Rolling Code Programming"
section.
4. Repeat step 2 to program the remaining
HomeLink buttons.
Additional Programming for Rolling Code
Devices
For any rolling-code-equipped device; follow
the steps below after completing the "Program-
ming" section. A second person may make the
following steps easier.
1. Locate the "learn" or "smart" button on the
device's motor head unit. The exact location
and color of the button varies by product
brand, but is usually referenced in the device's
owner's manual. Contact HomeLink at 1-
800-355-3515 or www.homelink.com for
help.
2. Press and release the "learn" or "smart"
button on the device's motor head unit.
NOTE:You now have 30 seconds to initiate step 3.
3. Return to the vehicle and firmly press and
release the programmed HomeLink button.
Press and release the same HomeLink but-
ton a second time to complete the program-
ming process. (Some devices may require
you to press and release a third time to
complete the programming.)
4. Now HomeLink mirror and rolling-code-
equipped device should be synchronized.
The remaining HomeLink buttons may now
be programmed if this has not been done
previously.
