NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions
and the procedure, and precautions in the Repair Manual applicable for the model year.

reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power
