There are a few ways to turn off the airbag light on your Toyota RAV4. One way is to disconnect the battery for a minute or two, then reconnect it. This will reset the airbag system and should turn off the light. Another way is to use a code reader to clear the code that is causing the light to come on. If you don't have a code reader, you can take it to a dealership or auto parts store and they can clear the code for you.
