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.

ORS031082L
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
ORS031083
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
Information
With rollover sensor
The side and curtain air bags and the
front center side air bag may inflate in a
rollover situation, when it is detected by
the rollover sensor.
ORS031084L
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 collision energy is
absorbed by the vehicle structure.

Idle Stop and Go helps reduce fuel
consumption by automatically shutting
down the engine, when the vehicle is
at a standstill (for example, red stop
light, stop sign, and traffic jam) subject
to certain prerequisite conditions being
satisfied as listed below.
The engine is automatically started upon
satisfying the starting conditions.
ISG system is always active, when the
engine is running.
Information
When the engine is automatically started
by ISG system, warning lights (for
example, ABS, ESC, ESC OFF, MDPS,
and parking brake warning light) may
illuminate for a few seconds due to low
battery voltage.
However, it does not indicate a
malfunction with ISG system.
ISG System Operation
Prerequisite for activation
