During 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 to
inflate if necessary) only when the
Engine Start/Stop button is in the
ON or START position.
• Air bags inflate in the event of cer-
tain frontal or side collisions to help
protect the occupants from serious
physical injury.
• Generally, air bags are designed to
inflate based upon the severity of a
collision, its direction, etc. These
two factors determine whether the
sensors produce an electronic
deployment/inflation signal.
• 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.
• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which to
inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises
and broken bones because the
inflation speed also causes the air
bags to expand with a great deal of
force.
• There are even circumstances
under which contact with the air
bag can cause fatal injuries, espe-
cially if the occupant is positioned
excessively close to the air bag.
You can take steps to help reduce
the risk of being injured by an inflat-
ing air bag. The greatest risk is sitting
too close to the air bag. An air bag
needs about 10 inches (25 cm) of
space to inflate. NHTSA recom-
mends that drivers allow at least 10
inches (25 cm) between the center of
the steering wheel and the chest.

Proper seated position for OCS
If the "PASSENGER AIR BAG OFF"
indicator is on when an adult is seat-
ed in the front passenger seat, place
the Engine Start/Stop button in the
OFF position and ask the passenger
to sit properly (sitting upright with the
seat back in an upright position, cen-
tered on the seat cushion with their
seat belt on, legs comfortably
extended and their feet on the floor).
Restart the engine and have the per-
son remain in that position. This will
allow the system to detect the person
and to enable the passenger air bag.
If the "PASSENGER AIR BAG OFF"
indicator is still on, ask the passen-
ger to move to the rear seat.
Information
The "PASSENGER AIR BAG OFF"
indicator illuminates for approximate-
ly 4 seconds after the Engine Start/
Stop button is in the OFF position or
after the engine is started. If the front
passenger seat is occupied, the OCS
will then classify the front passenger
after several more seconds.
i
Never allow an adult passenger
to ride in the front passenger
seat when the "PASSENGER
AIR BAG OFF" indicator is illu-
minated. During a collision, the
air bag will not inflate if the indi-
cator is illuminated. Have your
passenger reposition himself in
the seat. If the "PASSENGER
AIR BAG OFF" indicator
remains illuminated after the
passenger repositions himself
properly and the vehicle is
restarted, have the passenger
move to the rear seat because
the air bag will not inflate.

Safety system of your vehicle
Do Not Install a Child Restraint
in the Front Passenger's Seat
Even though your vehicle is
equipped with the OCS, never install
a child restraint in the front passen-
ger’s seat. An inflating air bag can
forcefully strike a child or child
restraint resulting in serious or fatal
injury.
Why Didn't My Air Bag Go Off
in a Collision?
Air bags are not designed to inflate in
every collision. There are certain
types of accidents in which the air
bag would not be expected to pro-
vide additional protection. These
include rear impacts, second or third
collisions in multiple impact acci-
dents, as well as low speed impacts.
Damage to the vehicle indicates a
collision energy absorption, and is
not an indicator of whether or not an
air bag should have inflated.
• NEVER place a rearward-fac-
ing or forward-facing child
restraint in the front passen-
ger's seat of the vehicle.
• An inflating frontal air bag
could forcefully strike a child
resulting in serious injury or
death.
• Always properly restrain chil-
dren in an appropriate child
restraint in the rear seat of the
vehicle.
WARNING
OHI039193N
To reduce the risk of an air bag
deploying unexpectedly and
causing serious injury or death:
• Do not hit or allow any objects
to impact the locations where
air bags or sensors are
installed.
• Do not perform maintenance
on or around the air bag sen-
sors. If the location or angle of
the sensors is altered, the air
bags may deploy when they
should not or may not deploy
when they should.
• Do not install bumper guards
or replace the bumper with a
non-Genuine Genesis Part.
This may adversely affect the
collision and air bag deploy-
ment performance.
• Press the Engine Start/Stop
button to the OFF or ACC
position when the vehicle is
being towed to prevent inad-
vertent air bag deployment.
• Have all air bag repairs con-
ducted by an authorized
retailer of Genesis Branded
products.
WARNING

02
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 illuminate
when the Engine Start/Stop button is
in the ON position, or continuously
remains on, have your vehicle imme-
diately inspected by an authorized
retailer of Genesis Branded products.
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 retailer of Genesis
Branded products. Improper han-
dling of the SRS system may result
in serious personal injury.
OHI039165N
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.

Additional Safety Precautions
Passengers should not move out of
or change seats while the vehicle is
moving.A passenger who is not
wearing a seat belt during a crash or
emergency stop can be thrown
against the inside of the vehicle,
against other occupants, or be ejected
from the vehicle.
Do not use any accessories on seat
belts.Devices claiming to improve
occupant comfort or reposition the
seat belt can reduce the protection
provided by the seat belt and increase
the chance of serious injury in a crash.
Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the sup-
plemental restraint system sensing
components or side air bags.
Do not place items under the front
seats.Placing items under the front
seats could interfere with the opera-
tion of the supplemental restraint sys-
tem sensing components and wiring
harnesses.
Do not cause impact to the doors.
Impact to the doors when the Engine
Start/Stop button is in the ON position
may cause the air bags to inflate.
Modifications to accommodate
disabilities.If you require modifica-
tion to your vehicle to accommodate
a disability, contact Genesis
Customer Care at 844 340-9741
Adding equipment to or modify-
ing your air bag equipped vehicle
If you modify your vehicle by changing
your vehicle’s frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle’s air bag system. • Always have inflated air bags
replaced by an authorized
retailer of Genesis Branded
products.
• If components of the air bag
system must be discarded, or
if the vehicle must be
scrapped, certain safety pre-
cautions must be observed.
Consult an authorized retailer
of Genesis Branded products
for the necessary information.
Failure to follow these precau-
tions could increase the risk
of personal injury.
