Side air bags
Your vehicle is equipped with a side
air bag in each front seat and out-
board rear seats. The purpose of the
air bag is to provide the vehicle's
driver and the front passenger with
additional protection than that
offered by the seat belt alone.The side air bags are designed to
deploy only during certain side impact
collisions, depending on the crash
severity.
The side and curtain air bags on both
sides of the vehicle may deploy if a
rollover or possible rollover is detect-
ed.
For vehicles equipped with a rollover
sensor the side air bags and pre-ten-
sioners on both sides of the vehicle
may deploy if a rollover or possible
rollover is detected. However, the
side air bags are not designed to
deploy in all side impact or rollover
situations.

To reduce the risk of serious
injury or death from an inflating
side air bag, take the following
precautions:
• Seat belts must be worn at all
times to help keep occupants
positioned properly.
• Do not allow passengers to
lean their heads or bodies
onto doors, put their arms on
the doors, stretch their arms
out of the window, or place
objects between the doors
and seats.
• Hold the steering wheel at the
9 o'clock and 3 o'clock posi-
tions, to minimize the risk of
injuries to your hands and
arms.
• Do not use any accessory
seat covers. This could reduce
or prevent the effectiveness
of the system.

How Does the Air Bags
System Operate?
The SRS consists of the following
components:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side air bag modules (front)
4. Side air bag modules (rear)
5. Curtain air bag modules
6. Retractor pre-tensioner assemblies
7. Air bag warning light
8. SRS control module (SRSCM)
/ Rollover sensor
9. Front impact sensors
10. Side impact sensors
(acceleration)
11. Side impact sensors (pressure)
12. Driver's knee air bag module
13. Emergency fastening device
14. Occupant classification system
15. Driver's and front passenger's
seat belt buckle sensors
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the Engine Start/Stop button is in the
ON or START position to determine if
a crash impact is severe enough to
require air bag deployment or pre-ten-
sioner seat belt deployment. To reduce the risk of serious
injury or death from an inflating
curtain air bags, take the follow-
ing precautions:
• All seat occupants must wear
seat belts at all times to help
keep occupants positioned
properly.
• Properly secure child
restraints as far away from the
door as possible.
• Do not place any objects over
the air bag. Also, do not attach
any objects around the area
the air bag inflates such as
the door, side door glass,
front and rear pillar, roof side
rail.
• Do not hang other objects
except clothes, especially
hard or breakable objects. In
an accident, it may cause
vehicle damage or personal
injury.
• Do not allow passengers to
lean their heads or bodies
onto doors, put their arms on
the doors, stretch their arms
out of the window, or place
objects between the doors
and seats.
• Do not open or repair the side
curtain air bags.

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.

2-66
Safety system of your vehicle
When the SRSCM detects a suffi-
ciently severe impact to the front of
the vehicle, it will automatically
deploy the front air bags.
Upon deployment, tear seams mold-
ed directly into the pad covers will
separate under pressure from the
expansion of the air bags. Further
opening of the covers allows full
inflation of the air bags.
A fully inflated air bag, in combina-
tion with a properly worn seat belt,
slows the driver or the front passen-
ger forward motion, reducing the risk
of head and chest injury. To reduce the risk of serious
injury or death from an inflating
air bag, take the following pre-
cautions:
• NEVER place a child restraint
in the front passenger seat.
Always properly restrain chil-
dren under age 13 in the rear
seats of the vehicle.
• Adjust the front passenger’s
and driver's seats as far to the
rear as possible while allow-
ing you to maintain full con-
trol of the vehicle.
• Hold the steering wheel with
hands at the 9 o'clock and 3
o'clock positions.
• Never place anything or any-
one between the air bag and
the seat occupant.
• Do not allow the front passen-
ger to place their feet or legs
on the dashboard.

Safety system of your vehicle
Noise and smoke from inflating
air bag
When the air bags inflate, they make
a loud noise and may produce
smoke and powder in the air inside of
the vehicle. This is normal and is a
result of the ignition of the air bag
inflator. After the air bag inflates, you
may feel substantial discomfort in
breathing because of the contact of
your chest with both the seat belt and
the air bag, as well as from breathing
the smoke and powder. The powder
may aggravate asthma for some
people. If you experience breathing
problems after an air bag deploy-
ment, seek medical attention imme-
diately.
Though the smoke and powder are
nontoxic, they may cause irritation to
the skin, eyes, nose, throat, etc. If
this is the case, wash and rinse with
cold water immediately and seek
medical attention if the symptoms
persist.
Occupant Classification
System (OCS)
Your vehicle is equipped with an
Occupant Classification System in
the front passenger's seat.
Main components of the
Occupant Classification System
• A detection device located within
the front passenger seat cushion.
• Electronic system to determine
whether the passenger air bag sys-
tems should be activated or deacti-
vated.
• An indicator light located on the
instrument panel which illuminates
the words "PASSENGER AIR BAG
OFF" indicating the front passen-
ger air bag system is deactivated.
• The instrument panel air bag indi-
cator light is interconnected with
the OCS.

Main components of the
Occupant Classification System
The OCS is designed to help 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 purpose is to help reduce the
risk of injury or death from an inflat-
ing air bag to certain front passenger
seat occupants, such as children, by
requiring the air bag to be automati-
cally turned OFF.
For example, if a child restraint of the
type specified in the regulations is on
the seat, the occupant classification
sensor can detect it and cause the
air bag to turn OFF.
Front passenger seat adult occu-
pants who are properly seated and
wearing the seat belt properly,
should not cause the passenger air
bag to be automatically turned OFF.
For small adults it may be turned
OFF, however, if the occupant does
not sit in the seat properly (for exam-
ple, by not sitting upright, by sitting
on the edge of the seat, or by other-
wise being out of position), this could
cause the sensor to turn the air bag
OFF.
You will find the "PASSENGER AIR
BAG OFF" indicator on the overhead
console. This system detects the
conditions 1-4 in the following table
and activates or deactivates the front
passenger air bag based on these
conditions.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 center
console.
• 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.

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.
WARNING
OHI038118

2-77
If the vehicle chassis is impacted by
bumps or objects on unimproved
roads, the air bags may deploy. Drive
carefully on unimproved roads or on
surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.
Air bag non-inflation conditions
In certain low-speed collisions the air
bags may not deploy. The air bags
are designed not to deploy in such
cases because they may not provide
benefits beyond the protection of the
seat belts.Front air bags are not designed to
inflate in rear collisions, because
occupants are moved backward by
the force of the impact. In this case,
inflated air bags would not provide
any additional benefit.
Front air bags may not inflate in side
impact collisions, because occu-
pants move in the direction of the
collision, and thus in side impacts,
front air bag deployment would not
provide additional occupant protec-
tion.
However, side and curtain air bags
may inflate depending on the intensi-
ty, vehicle speed and angles of
impact.

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.
