A large quantity of non-toxic gas (nitrogen gas) is generated with a loud noise when the air bag or
seat belt pretensioner deploys. If these airborne particles irritate your skin, eyes, nose, or throat, rinse
the area with cool water. If the irritation continues, see your doctor.
The windshield glass may be broken when the passenger air bag deploys.
The air bag is a unit to save an occupant's life from a sudden accident and it inflates at a very fast
speed by gas with high temperature, which might cause injury, such as an abrasion, bruise and burn
depending on the accident conditions.
The air bag components will be very hot after deployment. Do not touch them.
The deployed air bag/seat belt pretensioner cannot deploy again. It will work when an additional
impact is applied. Once the air bag system is triggered, the triggered air bag assembly should be
removed from the vehicle and replaced with a new one.
The air bag warning lamp is illuminated for 3 to 7 seconds after the engine is started to check
the system. If this warning lamp remains ON, then the system may be defective. Have the air
bag system checked immediately by Ssangyong Dealer or Ssangyong Authorized Service
Operation.
Incorrect inspection can result in serious injuries or malfunctions in the air bag and seat belt
pretensioner system. 12.

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

Driver air bag
The air bag is installed at the center of the
steering wheel. The inflator of this air bag is
ignited momentarily in the event of a collision
and deploys the air bag cushion.
Air bag unit (SDM)
The air bag unit is installed in
the front side of the front
console, and it monitors the
air bag system and
determines the air bag
deployment in the event of a
collision.Front impact sensor
The front impact sensors are fitted
at the bottom of both LH and RH
headlamp inside the front
bumper, and output signals that
activates the front air bag system.
Air bag warning lamp
This lamp notifies the driver about the result of the
diagnosis and faults.
Passenger air bag
This air bag is installed in the upper side
of the instrument panel on the
passenger side. It activates in the same
way of the driver air bag.
2. AIR BAG SYSTEM LAYOUT
Passenger Air Bag ON/OFF Switch
The front passenger air bag is disabled (not
inflatable) when placing the passenger air bag
switch is located on the right side of the
instrument panel, and you can see it when
opening the front passenger door. Press and
turn this switch to operate.

8810-00
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
