The airbag system should be checked 10 years from the manufacture date on the certification label, and every two years thereafter. The check involves a visual inspection of the airbag cover (s) for any damage, initiating the airbag self-diagnostic system, and using a diagnostic tester to check for codes. Removing the steering-wheel airbag to check the condition of the wires and connections may also be recommended. The specific recommendation for a given year and model may be found in the appropriate Repair Manual. A qualified technician, preferably a Lexus dealer, should perform these services. If the SRS airbag light is illuminated on the dash, the vehicle should be immediately inspected and repaired by a Lexus dealer. If the light is on, the system may not operate in the event of a collision.
