If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your
airbag system may not work properly. Have your vehicle
serviced right away.
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. The
light should go out and the
system is ready.
CAUTION:
{
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the airbag
readiness light stays on after you start your
vehicle.
The airbag readiness light should flash for a few seconds
when the engine is started. If the light does not come on
then, have it fixed so it will be ready to warn you if there is
a problem.
