SAFETYBELT EXTENDER
If the vehicle's safety belt will fasten around you, you should use it.
But if a safety belt isn't long enough to fasten, your dealer will order you
an extender. It's free. When you go in to order it, take the heaviest coat
you will wear, so the extender will be long enough for you. The extender
will be just for you, and just for the seat in your vehicle that you choose.
Don't let someone else use it, and use it only for the seat it is made to fit.
To wear it, just attach it to the regular safety belt.
CHECKING YOUR R E S T M N T SYSTEMS
Now and then, make sure all your belts, buckles, latch plates, retractors,
anchorages and reminder systems are working properly. Look for any
loose parts or damage. If you see anything that might keep a restraint
system from doing its job, have it repaired.
REPUCING SAFETYBELTSAFTER A
CRASH
If you've had a crash, do you need new belts?
After a very minor collision, nothing may be necessary. But if the belts
were stretched, as they would be if worn during a more severe crash, then
you need new belts.
If belts are cut or damaged, replace them. Collision damage also may
mean you will have to have safety belt parts, like the retractor, replaced
or anchorage locations repaired -- even if the belt wasn't being used at
the time of the collision.
