If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come

status indicator, it means that the passenger sensing
system has turned off the right front passenger
frontal airbag.
If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be
a problem with the lights or the passenger sensing
system. See your dealer/retailer for service.

started. If it does not come on then, have it fixed so it
will be ready to warn if there is a problem.When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
stays on if the parking brake does not fully release. If it
stays on after the parking brake is fully released, it means
