You do not need to, and should not, perform any maintenance on or replace any airbag system components yourself. However, you should have your vehicle inspected by a dealer in the following situations:
When the airbags have deployed
If an airbag has inflated, the control unit and other related parts must be replaced.
Similarly, once an automatic seat belt tensioner has been activated, it must be replaced.
When the vehicle has been in a moderate-to-severe collision
Even if the airbags did not inflate, have your dealer inspect the following: the driver’s seat position sensor, weight sensors in the passenger’s seat, front seat belt tensioners, and each seat belt that was worn during the crash.
Do not remove or modify a front seat without consulting a dealer
This would likely disable or affect the proper operation of the driver’s seat position sensor or the weight sensors in the passenger’s seat. If it is necessary to remove or modify a front seat to accommodate a person with disabilities, contact a Honda dealer, or for U.S. vehicles, American Honda Automobile Customer Service at 1-800- 999-1009 and for Canadian vehicles, Honda Canada Customer Relations at 1-888- 9-HONDA-9.
Airbag Care
We recommend against the use of salvaged airbag system components, including the airbag, tensioners, sensors, and control unit.
