   If equipped with an air bag system, wait 10 minutes after disconnecting the negative battery cable before performing any further work while the system fully de-energizes in order to avoid accidental deployment. All air bag system wiring is yellow. Do not use electrically powered test equipment on these circuits.

2. Drain the cooling system into a clean container for reuse.
3. Disconnect the heater hoses from the heater core. Plug the heater core and heater hoses.
4. Remove the instrument panel by:
   • Remove the center console assembly retaining screws and remove the center console.
   • Remove the front A pillar upper trim pieces.
   • Remove the radio grounding wire, which is screwed to the floor just behind the shifter assembly.
