3. CAUTIONS FOR AIR BAG SYSTEM
Cautions for air bag maintenance
Whenever installing or removing the devices related to the air bag system, disconnect the negative
battery cable and wait for at least 30 seconds.
Do not connect a tester probe to the inflator to measure the resistance of the component of the air
bag system. The detonator of the inflator may explode due to a sudden extra power supplied by the
tester.
Note that the used components related to the air bag system, especially the air bag unit, should be
packed in an air tight container and prevent it from any impact or damage.
When there is any deployed air bag (including curtain air bag and seat belt pretensioner), the entire
system including the air bag unit should be replaced. The deployed air bag unit should not be reused
since it has status data when it is deployed, and the data cannot be cleared with a diagnostic device.
The air bag and seat belt pretensioner systems contain explosive charges, so handle carefully when
disposing or replacing them. 1.

Cautions for air bag maintenance
Do not modify, change or apply impact on any air bag component. The air bag may be deployed
abruptly, causing serious injuries.
Children and infants should ride in a rear seat. Seating in the passenger seat with carrying a
child or infant is strictly prohibited. An infant or a child could be severely injured by the air bag
deployment.
A child restraint system must not be installed on the front seat. An infant or a child could be severely
injured by the air bag deployment when it is fitted to the passenger seat.
Do not place any objects on the air bag inflation location. You may get injured by those objects during
deployment.
Never put your arms around the front seat from behind, lean on the front seatback, or put your arms
out of the window. You can severely injured when the side air bag deploys.
Never lean on the door since it becomes very dangerous when the side air bag deploys.
The side air bag deploys when there is a severe side collision.
Do not slam the front door to close it. The side air bag may deploy unexpectedly.
When an occupant fastens the seat belt in an unstable or inclined posture, the air bag system cannot
protect the occupant properly. Moreover, the occupant can be injured by the air bag.
Do not move your seat too close to the steering wheel or dashboard. Being too close to the
steering wheel or instrument panel during the air bag deployment could cause serious injury,
including death
Hold only the outer rim of the steering so that the air bag can inflate without any hindrance.
Do not incline toward the steering wheel. Never allow the passenger to put hands or feet on the dash
board. The air bag cannot work properly Do not hold and operate the steering wheel by crossing your
arms You could get seriously injured when the air bag deploys. 1.

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
