GMC Sierra Owners Manual
Replacing Airbag System Parts after a Crash
A crash can damage the airbag systems in the vehicle.
A damaged airbag system may not work properly and may not protect you and your passenger(s) in a crash, resulting in serious injury or even death. To help make sure the airbag systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.
If an airbag inflates, you will need to replace airbag system parts. See your dealer for service.
If the airbag readiness light stays on after the vehicle is started or comes on when you are driving, the airbag system may not work properly. Have the vehicle serviced right away. See Airbag Readiness Light on page 5‑20 for more information.
