Safety features of your vehicle
Occupant classification system
Your vehicle is equipped with an
occupant classification system in the
front passenger's seat.
The occupant classification system
is designed to detect the presence of
a properly-seated front passenger
and determine if the passenger's
front air bag should be enabled (may
inflate) or not. The driver's front air
bag is not affected or controlled by
the occupant classification system.
(Continued)If the SRS air bag warning light
" " does not illuminate, or
continuously remains on after
illuminating for about 6 sec-
onds when the ignition switch
is turned to the ON position, or
after the engine is started,
comes on while driving, the
SRS is not working properly. If
this occurs, have your vehicle
immediately inspected by an
authorized HYUNDAI dealer.
Before you replace a fuse or disconnect a battery terminal,
turn the ignition switch to the
LOCK position and remove
the ignition key for ignition
key, and turn the engine
start/stop button to the OFF
position for smart key. Never
remove or replace the air bag
related fuse(s) when the igni-
tion switch is in the ON posi-
tion. Failure to heed this warn-
ing will cause the SRS air bag
warning light to illuminate.
OGD032073N
WARNING
If an air bag deploys, theremay be a loud noise followed
by a fine dust released in the
vehicle. These conditions are
normal and are not hazardous
- the air bags are packed in
this fine powder. The dust
generated during air bag
deployment may cause skin
or eye irritation as well as
aggravate asthma for some
persons. Always wash all
exposed skin areas thorough-
ly with lukewarm water and a
mild soap after an accident in
which the air bags were
deployed.
The SRS can function only when the ignition switch is in
the ON position.
