If the vehicle's safety belt will fasten around you, you should use it.
But if a safety belt is not long enough, your dealer/retailer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. To help avoid personal injury, do not let someone else use it, and use it only for the seat it is made to fit. The extender has been designed for adults. Never use it for securing child seats. To wear it, just attach it to the regular safety belt. For more information, see the instruction sheet that comes with the extender.
When a safety belt extender is installed in the right front passenger safety belt, make sure the passenger airbag status indicator displays ON. See Passenger Airbag Status Indicator. If the indicator shows OFF, disconnect the extender's latch from the buckle then reconnect the safety belt. The passenger airbag status indicator light should be ON and then the safety belt extender can be reconnected. If the safety belt extender is used while the passenger airbag status indicator light is OFF, the right front passenger frontal and seat-mounted side impact airbags (if equipped) may not activate correctly.
Always disconnect the extender from the safety belt after you use it so that the airbag will work properly the next time someone uses that seat.
