Pre-active Safety Seat (PSS) (if
equipped)
When Pre-active Safety Seat detects
a collision or hazardous situation, it
provides safety by repositioning the seat
as follows:

[Seatback (power passenger seat and
rear seat): Raises the seatback when
reclined.

[Seat cushion (power rear seat): If
the cushion height is low, raises the
cushion.
WARNING
Pre-active Safety Seat is a
supplementary device. The driver
should keep their eyes on the road and
verify that there are no obstructions
ahead. If there are no passengers or the
seatbelts are not fastened, the system
will not function.
System operation

[Pre-active Safety Seat limits
passenger’s movement and helps
decrease the chance of injury by
raising the seatback right before
collision to tighten the seatbelt.
The system may operate under the
following situations:
- The brake pedal was depressed
abruptly.
- The vehicle is difficult to control.
- Collision risk is considered high by
the vehicle distance sensor.
[Pre-active Safety Seat helps prevent
the passenger from leaning forward
or to the side by raising the seatback
during sudden braking or rapid
turning to tighten the seatbelt.
The system may operate under the
following situations:
- The upper body is leaned forward
due to sudden braking.
- The upper body is leaned to the side
due to rapid turning.
- Driving on a slippery icy road.
- There is high risk of a rollover.
System pause
If the passenger adjusts the seat
manually, the system stops immediately.
However, it restarts to operate after 5
seconds when the hazardous situation
continues.
System malfunction
If the Pre-active Safety Seat system does
not operate properly, have the vehicle
inspected by an authorized retailer of
Genesis Branded products.

NOTICE
The sensor that activates the SRS
control module is connected with the
pre–tensioner seat belts. The SRS air
bag warning light on the instrument
cluster will illuminate for approximately
three to six seconds after the Engine
Start/Stop button is in the ON position,
and then it should turn off.
If the pre-tensioner is not working
properly, the warning light will
illuminate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminated
or illuminates when the vehicle is being
driven, have the pre-tensioner seat
belts and/or SRS control module be
inspected by an authorized retailer of
Genesis Branded products as soon as
possible.
Information

[Pre-tensioner seat belts may be
activated in certain frontal or side
collisions or rollover situations.

[When the pre-tensioner seat belts are
activated, a loud noise may be heard
and fine dust, which may appear to be
smoke, may be visible in the passenger
compartment. These are normal
operating conditions and are not
hazardous.

[Although it is non-toxic, the fine dust
may cause skin irritation and should
not be inhaled for prolonged periods.
Wash all exposed skin areas thoroughly
after an accident in which the pre-
tensioner seat belts were activated.
WARNING

[Fasten your seat belt while sitting
properly in an upright position to
maximize the effectiveness of the
pre-tensioner seat belt system.

[A pre-tensioner seat belt system
is designed to activate only once.
Replace the pre-tensioner seat belt
system, if it was activated in an
accident.
Pre-Active Seat Belt (PSB)
(if equipped)
The purpose of the Pre-Active Seat Belt is
to tighten the seat belt when a collision
is sensed, during emergency braking, or
when a loss of control is sensed.
NOTICE
Pre-Active Seat Belt is a supplementary
system. Pre-Active Seat Belt activates
only when the passenger is wearing his/
her seat belt.
Pre-Active Seat Belt operation
In order to maximize the safety of the
passenger, Pre-Active Seat Belt system
operates as below.

[Full retraction
The seat belt is tightened when:
- Emergency braking situation occurs
- Losing control of the vehicle
- The vehicle senses a collision
- Driving on a slippery frozen road
- Unstable rolling of the vehicle
occurs

[Slack removal
Tightens a lose seat belt when
the seatbelt is fastened.

[Belt parking
Tightens a loose seat belt when the
seat belt is unfastened.

Side air bags and front center side
air (if equipped)
ORS031064
ORS031065
ORS031075
A : Side air bag (Front row),
B : Side air bag (Second row),
C : Front center side air bag (Driver’s seat)
Your vehicle is equipped with a side air
bag in each front and outboard second
row seat. Additionally, a front center
side air bag is provided in the inboard
side of the driver seatback. The purpose
of the air bag is to provide the vehicle’s
additional protection than that offered by
the seat belt alone.
The side air bags and front center side
air bag are designed to deploy during
certain side impact collisions, depending
on the crash severity.
For vehicles equipped with a rollover
sensor the front center side air bag,
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 side air bags and front center side air
bag are not designed to deploy in all side
impact or rollover situations.

3-62
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.

3-64
Safety System
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident, increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:

[The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.

[The light stays on after illuminating
for approximately three to six
seconds.

[The light comes on while the vehicle
is in motion.

[The light blinks when the engine is
running.
Have an authorized retailer of Genesis
Branded products inspect the SRS
as soon as possible if any of these
conditions occur.
During a moderate to severe frontal
collision, sensors will detect the
vehicle’s rapid deceleration. If the rate of
deceleration is high enough, the control
unit will inflate the front air bags, at the
time and with the force needed.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover by supporting the side upper
body area.
[Air bags are activated (able to inflate
if necessary) only when the Engine
Start/Stop button is in the ON or
START position and it can be activated
within about 3 minutes after the
engine is turned off.

[Air bags inflate in the event of certain
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 collision and its direction.
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 accident. It is
much more likely that you will simply
see the deflated air bags hanging out
of their storage compartments after
the collision.

[In addition to inflating in serious side
collisions, vehicles equipped with a
rollover sensor, side and/or curtain air
bags and front center side air bag will
inflate if the sensing system detects a
rollover.
When a rollover is detected, curtain
air bags will remain inflated longer to
help provide protection from ejection,
especially when used in conjunction
with the seat belts.

3-68
Safety System
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 occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For smaller adults it may turn
off. However, if the occupant does not
sit in the seat properly (for example, by
not sitting upright, by sitting on the edge
of the seat, or by otherwise being out of
position), this could cause the sensor to
turn the air bag OFF.
You will find the “PASSENGER AIR BAG
OFF” indicator overhead console panel.
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 vehicle
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 clothes like ski wear
or hip protection wear.

[Putting an additional thick cushion on
the seat.

[Putting electrical devices (for
example, notebook, satellite radio) on
the seat with inverter charging.

3-71

ORS031117

[NEVER lean on the door or center console or sit on
one side of the front passenger seat.
ORS031060

[Do not sit on the passenger seat wearing heavily
padded clothes such as ski wear and hip protector.
ORS031062

[Do not use car seat accessories such as thick blankets
and cushions which cover up the car seat surface.
ORS031061

[Do not place electronic devices such as laptops, DVD
player, or conductive materials such as water bottles
on the passenger seat.

[Do not use electronic devices such as laptops and
satellite radios which use inverter chargers.
ORS031063

[If large quantity of liquid has been spilled on the
passenger seat, the air bag warning light may
illuminate or malfunction.
Therefore, make sure the seat has been completely
dried before driving the vehicle.

[Do not place sharp objects on the front passenger seat. These may damage the
occupant detection system, if they puncture the seat cushion.

[Do not place any items under the front passenger seat.

[When replacing the seat, use original Genesis parts only. The OCS has been
developed based on using original Genesis parts car seats only. Altering or
changing the authentic parts may result in system malfunction and increase
risk of injury when in collision. Any of the above could interfere with the proper
operation of the OCS sensor thereby increasing the risk of an injury in an
accident.

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.
