Airbag Care
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 te nsioner 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 yo ur 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 passenge r’s seat. If it is necessary to remove or
modify a front seat to accommodate a pe rson 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.
1 Airbag Care
We recommend against the use of salvaged airbag
system components, includi ng the airbag, tensioners,
sensors, and control unit.
