2019 Hyundai Sonata warning light

2-52
Safety system of your vehicleDuring a frontal collision, sensors will
detect the vehicle's deceleration. If
the rate of deceleration is high
enough, the control unit will inflate
the front air bags.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in
which seat belts alone cannot pro-
vide adequate restraint. When need-
ed, the side air bags help provide
protection in the event of a side
impact or rollover.
Air bags are activated (able toinflate if necessary) only when the
ignition switch is in the ON position.
Air bags inflate in the event of cer- tain frontal or side collisions to help
protect the occupants from serious
physical injury.
There is no single speed at which the air bags will inflate. Generally,
air bags are designed to inflate
based upon the severity of a colli-
sion and its direction. These two
factors determine whether the sen-
sors produce an electronic deploy-
ment/inflation signal. Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the
density and stiffness of the vehicles
or objects which your vehicle
impacts during a collision. The
determining factors are not limited
to those mentioned above.
The front air bags will completely inflate and deflate in an instant. It is
virtually impossible for you to see
the air bags inflate during an acci-
dent. It is much more likely that you
will simply see the deflated air bags
hanging out of their storage com-
partments after the collision.
In addition to inflating in certain side collisions, vehicles equipped
with a rollover sensor, side and
curtain air bags will inflate if the
sensing system detects a rollover.
When a rollover is detected, side
and curtain air bags will remain
inflated longer to help provide pro-
tection from ejection, especially
when used in conjunction with the
seat belts.
If your SRS malfunctions, the air
bag may not inflate properly dur-
ing an accident increasing the
risk of serious injury or death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
The light stays on after illumi-
nating for approximately six
seconds.
The light comes on while the
vehicle is in motion.
The light blinks when the
engine is running.
Have an authorized HYUNDAI
dealer inspect the SRS as soon
as possible if any of these con-
ditions occur.

Safety system of your vehicle

Always be sure that you and all vehi-
cle occupants are seated properly
and wearing the seat belt properly for
the most effective protection by the
air bag and the seat belt.
The OCS may not function properly if
the passenger takes actions which
can affect the classification system.
These include:
Failing to sit in an upright position.
Leaning against the door or centerconsole.
Sitting towards the sides of the front of the seat.
Putting their legs on the dashboard or resting them on other locations
which reduce the passenger
weight on the front seat.
Wearing the seat belt improperly.
Reclining the seatback.
Wearing a thick cloth like ski wear or hip protection wear.
Putting an additional thick cushion on the seat.
Putting electrical devices (e.g. notebook, satellite radio) on the
seat with inverter charging.Condition and operation in the front passenger Occupant Classification System

and posture.

2Do not allow children to ride in the front passenger seat. When a larger child who has out- grown a child restraint system sits in the front passenger seat, the system may recognize
him/her as an adult depending upon his/her physique or sitting position.

3Never install a child restraint system on the front passenger seat.
*4The PASSENGER AIR BAG "OFF" indicator may turn on or off when a child above 12 months
to 12 years old (with or without child restraint system) sits in the front passenger seat. This is
a normal condition.

Safety system of your vehicle
Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated and the colli-
sion energy is absorbed by the vehi-
cle structure.
SRS Care
The SRS is virtually maintenance-
free and there are no parts you can
safely service by yourself. If the SRS
air bag warning light does not illumi-
nate when the Engine Start/Stop but-
ton is in the ON position, or continu-
ously remains on, have your vehicle
immediately inspected by an author-
ized HYUNDAI dealer.
Any work on the SRS system, such
as removing, installing, repairing, or
any work on the steering wheel, the
front passenger’s panel, front seats
and roof rails must be performed by
an authorized HYUNDAI dealer.
Improper handling of the SRS system
may result in serious personal injury. To reduce the risk of serious
injury or death, take the follow-
ing precautions:
Do not attempt to modify or
disconnect the SRS compo-
nents or wiring, including the
addition of any kind of badges
to the pad covers or modifica-
tions to the body structure.
Do not place objects over or
near the air bag modules on
the steering wheel, instrument
panel, or the front passen-
ger’s panel above the glove
box.
Clean the air bag pad covers
with a soft cloth moistened
with plain water. Solvents or
cleaners could adversely
affect the air bag covers and
proper deployment of the sys-
tem.
Always have inflated air bags
replaced by an authorized
HYUNDAI dealer.
