C. General Warnings for Air Bag
Do not check the circuits with a circuit tester. Do not attempt to modify any air bag component
including the steering wheel, air bag mountings and related wirings.
Do not subject any air bag component, such as the steering wheel, air bag mountings, wirings, to
impacts. You might get severely injured by sudden deployment of the air bag.
As the air bag/seat belt pretensioner parts are very hot after being deployed. Allow them to cool
down sufficiently before touching them.
The deployed air bag/seat belt pretensioner cannot deploy again. It will work when an additional
impact is applied. The components of the deployed air bag/seat belt pretensioner are non-reusable
parts. Therefore, remove or replace them as a unit.
The air bag and seat belt pretensioner systems contain explosive charges, so handle carefully when
disposing or replacing them.
Incorrect inspection can result in serious injuries or malfunctions in the air bag and seat belt
pretensioner system.
The air bag warning lamp is illuminated for 3 to 7 sec. after the engine is started to check the system.
Drive the vehicle after this warning lamp is turned off. If this warning lamp stays ON, the system may
be defective. Have the air bag system checked immediately by Ssangyong Dealer or Ssangyong
Authorized Service Center. -

4. CAUTIONS FOR AIR BAG OPERATION
When there is any deployed air bag (including curtain air bag and seat belt pretensioner), the air
bag unit should be replaced. Any DTC (Diagnostic Trouble Code) for the air bag unit should not
be cleared since it has status data when the air bag deployed.
Note that the used components related to the air bag system, especially the air bag unit, should
be packed in an air tight container to prevent any damage.
Do not connect a tester probe to the air bag connector or air bag body to measure the supply
voltage or resistance. The detonator may explode due to a sudden extra power supplied by the
tester.
Before removing or installing any air bag related components, disconnect the negative battery
cable. 1.

3.
4. When turning on the ignition switch, the air bag warning lamp is illuminated for about 6 sec. and then
goes off.
If the air bag warning lamp comes on or does not go off while the vehicle is driven, the air bag system is
faulty.

Once the ignition starts, the SDM starts to diagnose the air bag system during the ignition process.
If the system is OK, the SDM is armed for a specific impact on the vehicle. The ignition time takes about
6 sec.

3. DEPLOYMENT
According to the collision deceleration rate that each collision G sensor reads, the air bag unit sends out
about 2~4 or higher Amp current. This current generates some heat, which fires the detonator in the
inflator.
The table shows the basic inner resistance of the air bag related module and the basic instant current
necessary for firing.
1) Air Bag System Deployment (Firing Loop)
Do not connect a tester probe to the air bag connector or air bag body to measure the supply
voltage or resistance. The detonator may explode due to a sudden extra power supplied by the
tester.
Before removing or installing any air bag related components, disconnect the negative battery
cable. -
