SERVICE PRECAUTIONS

General Instructions

After all service, verify the air bag indicator. This means turn the ignition switch to RUN and count the flashes only after the code (series of flashes) has cycled twice. If the air bag indicator comes on continuously for 4 to 8 seconds and then goes out, the system is functioning properly and all faults have been serviced.
