GENERAL DESCRIPTION AND OPERATION

GENERAL PRECAUTIONS

When the ignition is switched ON, the supplemental
inflatable restraints (SIR) warning lamp must blink at
seven times for 7 seconds and then turn off.
There is a fault in the airbag system if the warning
lamp does not turn OFF or the warning lamp illuminates
while the vehicle is in operation. If the warning lamp
indicates there is a fault in the airbag system, assume
that the SIR system may not be functional.
Notice: Failure to follow all service procedures in the
correct sequence can cause the airbag system to
deploy unexpectedly and possibly cause a serious
injury.
•
Only trained personnel at franchised SsangYong
dealers and authorized SsangYong service
dealerships may service the airbag system.
•
Never attempt to disassemble, repair or reuse the
following component;
- Airbag modules
- Clock spring
- Sensing and diagnostic module
- Wiring harness
•
When repairing SIR component, follow the service
notice;
- Inspect any SIR part before it is installed.
- Use only new parts.
- Do not install used SIR parts from other vehicles.
- Do not install any part that has been dropped or
that has dents, cracks or other defects.
•
Before testing, disconnect the negative battery
cable. Wait one minute for the SDM capacitor to
discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is
disconnected. Unintentional deployment of the
airbags can cause injury.
