When pressing the tailgate switch for more than 0.1 second with driver door unlocked and vehicle
The tailgate open relay is turned OFF immediately after the driver door is locked or the vehicle speed
goes over 3 km/h during its operation.
When the tailgate switch on smart key is pressed in theft deterrent mode or with the smart key
detected by the exterior antenna, the SKM verifies the smart key and disarms the tailgate only. When
the tailgate is open and closed, the system enters into the theft deterrent mode again. If the tailgate
switch is not operated for 30 seconds, the system also does so.
The BCM checks that the verified smart key is in the luggage room 1 second after when the closed
tailgate is detected by the tailgate open switch with power OFF.
If there is a verified smart key in the luggage room when the tailgate is open and closed in theft
deterrent mode, the external buzzer sounds for 5 seconds.
When the driver press the tailgate open switch in order to look for the smart key, the BCM deactivates
lock so that the tailgate can be opened even though the driver door is locked. (maintains standby for
opening without verification) 1.

1. AIR BAG SYSTEM OVERVIEW
The air bag system is divided into front air bag system and side air bag system. The system protects the
occupant's body by deploying the air bags in the event of a collision. The system consists of 8 inflators
including the inflators of the seat belt pretensioners, air bag unit (SDM), and 4 impact sensors on the
front side and both sides of the vehicle. The air bag unit (SDM) determines the operation of each air bag
module and seat belt pretensioners using the crash signals from the front and side impact sensors in the
event of a collision. The front and side air bag systems are operated independently, and the body control
module (BCM) activates the auto door unlock function and various lamps including hazard warning lamp
and room lamps, when the crash signal from the SDM is received to notify others of emergency situation
and let the occupant escape easily. The SDM is equipped with self diagnosis function, and it performs
the diagnosis on the internal/external devices of the air bag system for a certain period of time after IGN
ON. And it monitors the air bag system regularly and turns on the air bag warning lamp on the
instrument cluster when a fault is found in the system, to notify the driver. The SDM has event data
recorder (EDR) function that stores the driving information data transmitted through CAN communication
from various units (vehicle speeds, engine rpm, brake application, etc.) in a crash or near crash event,
when the acceleration sensor in the air bag unit detects a sharp acceleration change, regardless of the
air bag deployment

Side air bag
The side air bags are installed in the
outer sides of the driver (LH) and
passenger (RH) seats to minimize
occupants' side injuries in case of a side
impact. This air bag is operated based
on the collision signal from the side
impact sensor.
Curtain air bag
The curtain air bags are installed to the upper end of
both doors. The air bag provides head protection for
the front and rear outboard occupants in a side
collision.Side impact sensor
The side impact sensors are fitted at the
bottom of both LH and RH B-pillars, and
output signals that activates the side air
bag system.
BCM (Crash signal)
The BCM activates the auto door
UNLOCK, hazard warning lamp, and
room lamps when a crash signal of the
air bag unit (SDM) is input.Seat belt pretensioner
The seat belt pretensioners of all seats are
operated at the same time, in the event of a
collision. They pull the seat belt and holds the
occupants in the seat to minimize the impact.

3. AIR BAG SYSTEM OPERATING PROCESS
1) Air Bag System Input/Output
The air bag unit (SDM) performs the internal/external diagnosis on the air bag system for about 6
seconds after IGN ON. The air bag unit is ready to deploy air bag after this diagnosis, and when a
certain level of collision occurs, it determines the deployment of the air bag using the signals from the
impact sensors, deploys the corresponding air bag, and stores the collision data and EDR data. The
body control module (BCM) activates the auto door unlock function and various lamps including hazard
warning lamp and room lamps, when the crash signal from the SDM is received to notify others of
emergency situation and let the occupant escape easily.
Major functions
Detects frontal and side collision (Rear-end collision only with EDR trigger)
Activates the front air bag, side air bag, curtain air bag and belt pretensioners
Indicates system readiness and faults to the driver by means of a fault warning lamp
Facilitates servicing capability via a serial diagnostic communication interfaces
Records crash data and DTCs
Keeps power for deployment of air bag even when the power to the air bag unit is cut off due to the
collision

4) Air Bag Deployment Signal to BCM
The air bag deployment signal from the air bag unit is sent to the BCM. This signal triggers the flash of
the hazard warning lamp to notify others of emergency situation, and is used as a signal that turns on the
room lamps and activates auto door unlock function for the occupants.
The air bag unit of a vehicle without side air bag system can also send the crash signal to the BCM
according to the value of the acceleration sensor to activate the auto door unlock and various lamps
including hazard warning lamp and room lamps.

(2) BCM control when air bag deployment signal is input
The UNLOCK by the air bag deployment signal takes priority over the LOCK/UNLOCK control from
other functions.
The LOCK/UNLOCK requests from other functions during or after the UNLOCK output by the air
bag signal are ignored. However, the LOCK control is carried out when the ignition switch is turned
to the "OFF" position.
The same request during the LOCK/UNLOCK output is ignored. However, the UNLOCK by the air
bag deployment signal or operation by the smart key is carried out.
When LOCK and UNLOCK outputs occur at the same time, the LOCK output is carried out and
UNLOCK is ignored. 1.
