Warning:
When performing service on or near the SIR
components or the SIR wiring, the SIR system must be disabled.
Refer to SIR Disabling and Enabling . Failure to observe the
correct procedure could cause deployment of the SIR components,
personal injury, or unnecessary SIR system repairs. |

system prevents deployment of the SIR air bags from the reserved
energy supply.
