To install the tether anchor:
1. Route the child restraint tether strap
over the child restraint seatback.
Route the tether strap under the
head restraint and between the head
restraint posts, or route the tether
strap over the top of the vehicle
seatback. Make sure the strap is not
twisted.
2. Connect the tether strap hook to the
tether anchor, then tighten the tether
strap according to the child seat
manufacturer’s instructions to firmly
secure the child restraint to the seat.
3. Check that the child restraint is
securely attached to the seat by
pushing and pulling the seat forward-
and-back and side-to-side.
Securing a child restraint with lap/
shoulder belt
When not using the LATCH system, all
child restraints must be secured to a
vehicle rear seat with the lap part of a
lap/shoulder belt.
WARNING
ALWAYS place a rear-facing child
restraint in the rear seat of the vehicle.
Placing a rear-facing child restraint in
the front seat can result in serious injury
or death if the child restraint is struck
by an inflating air bag.
ORS031051
Automatic locking mode
Since all passenger seat belts move
freely under normal conditions and
only lock under extreme or emergency
conditions (emergency locking mode),
you must manually pull the seat belt all
the way out to shift the retractor to the
“Automatic Locking” mode to secure a
child restraint.
The “Automatic Locking” mode will
help prevent the normal movement of
the child in the vehicle from causing
the seat belt to loosen and compromise
the child restraint system. To secure a
child restraint system, use the following
procedure.
To install a child restraint system on the
rear seats, do the following:
1. Place the child restraint system on a
rear seat and route the lap/ shoulder
belt around or through the child
restraint, following the restraint
manufacturer’s instructions. Be sure
the seat belt webbing is not twisted.
Information
When using the rear center seat belt, you
should also refer to the “Rear Seat Belt –
Passenger’s 3-point system” section in this
chapter.

WARNING
To reduce the risk of serious injury or
death from an inflating side air bag
and front center 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 positions, 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.

[Do not hang other objects except
clothes. In an accident it may cause
vehicle damage or personal injury
especially when air bag is inflated.
[Do not place any objects over the
air bag or between the air bag and
yourself. Also, do not attach any
objects around the area the air bag
inflates such as the door, side door
glass, front and rear pillar.

[Do not place any objects between
the door and the seat. They may
become dangerous projectiles if the
side air bag inflates.

[Do not install any accessories on the
side or near the side air bags.

[Do not cause impact to the doors
when the Engine Start/Stop button
is in the ON or START position as this
may cause the side air bags to inflate.

[If the seat or seat cover is damaged,
have the system serviced by an
authorized retailer of Genesis
Branded products.

Safety System
Curtain air bags
ORS031066
ORS031076
Curtain air bags are located along both
sides of the roof rails above the front and
rear doors.
They are designed to help protect the
heads of the front seat occupants and
the rear outboard seat occupants in
certain side impact collisions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity.For vehicles equipped with a rollover
sensor the side and/or curtain air bags
and pre-tensioners on both sides of
the vehicle may deploy if a rollover or
possible rollover is detected.
The curtain air bags are not designed
to deploy in all side impact or rollover
situations.
WARNING
To reduce the risk of serious injury or
death from an inflating curtain air bag,
take the following precautions:

[All seat occupants must wear
seat belts at all times to help keep
occupants positioned properly.

[Properly secure Child Restraint
System 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 attempt to open or repair
the side curtain air bags yourself.
If necessary, have the air back be
inspected by an authorized retailer of
Genesis Branded products.

How Does the Air Bags System
Operate?
ORS032054N
The SRS consists of the following
components:
M Driver’s front air bag module
N Passenger’s front air bag module
O Front center side air bag module
P Side air bag modules
Q Curtain air bag modules
R Front retractor pre-tensioner
S Air bag warning light
T SRS control module (SRSCM) /
Rollover sensor
U Front impact sensors
V Side impact sensors
Side pressure sensors
Driver’s knee air bag module
Driver’s and front passenger’s seat belt
buckle sensors
Rear retractor pre-tensioner (if
equipped)
Occupant classification systemThe SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the Engine Start/Stop button is ON to
determine if a crash impact is severe
enough to require air bag deployment or
pre-tensioner seat belt deployment.
SRS warning light
The SRS (Supplemental Restraint System)
air bag warning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your air
bag system, which could include your
side and/or curtain air bags used for
rollover protection.

Safety System
ORS031121
Proper seated position for OCS
If the “PASSENGER AIR BAG OFF”
indicator is on when an adult is seated
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, centered
on the seat cushion with their seat belt
on, legs comfortably extended and their
feet on the floor). Restart the engine and
have the person remain in t hat 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 passenger to
move to the rear seat.
WARNING
NEVER allow an adult passenger to ride
in the front passenger seat when the
“PASSENGER AIR BAG OFF” indicator
is illuminated. During a collision, the
air bag will not inflate if the indicator
is illuminated. Have your passenger
reposition themselves in the seat. If the
“PASSENGER AIR BAG OFF” indicator
remains illuminated after the passenger
repositions themselves properly
and the vehicle is restarted, have
the passenger move to the rear seat
because the air bag will not inflate.
NOTICE
The “PASSENGER AIR BAG OFF”
indicator generally illuminates for
approximately 4 seconds after the
Engine Start/Stop button is in the ON
position or after the engine is started.
But, if the ignition switch or ENGING
START/STOP button is turned to the ON
position within 3 minutes after ignition
OFF, the indicator does not illuminate.
If the front passenger seat is occupied,
the OCS will then classify the front
passenger after several more seconds.

Do Not Install a Child Restraint in the
Front Passenger’s Seat
OHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING

[NEVER place a rear-facing or front-
facing child restraint in the front
passenger’s seat of the vehicle.

[An inflating frontal air bag could
forcefully strike a child resulting in
serious injury or death.

[Always properly restrain children in
an appropriate child restraint in the
rear seat of the vehicle.
Why Didn’t My Air Bag Go Off In
a Collision?
There are certain types of accidents in
which the air bag would not be expected
to provide additional protection. These
include rear impacts, second or third
collisions in multiple impact accidents,
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.
Air bag collision sensors
WARNING
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 sensors. 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 deployment performance.

[Press the Engine Start/Stop button to
the OFF or ACC position and wait for
3 minutes, when the vehicle is being
towed to prevent inadvertent air bag
deployment.

[Have all air bag repairs performed
by an authorized retailer of Genesis
Branded products.

Safety System
Air bag non-inflation conditions
ORS031078L
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.
ORS031079L
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.
ORS031080L
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags and
the front center side air bag may inflate
depending on the severity of impact.
ORS031081
In an angled collision, the force of impact
may direct the occupants in a direction
where the air bags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any air bags.
