Air Bag System Light
There is an air bag readiness light on the instrument panel, which shows
AIR BAG
.
The system checks for electrical malfunctions, and the light tells
you if there is a problem.
You will see this light
flash for a few
seconds when you
turn your ignition to
RUN or START.
Then the light should
go out, which means
the system is ready.
Remember, if the air bag readiness light doesn't come on when you start
your vehicle, or stays on, or comes on when you are driving, your air bag
system may not work properly. Have your vehicle serviced right away.
