To take the jack out,
turn the wing nut to
the left and take it and
the retainer off. Take
the jack and storage
box out and then take
the tools out of the
box.
Your vehicle may have a pair of emergency gloves secured to the jack. You
can use them when changing the tire, or during other emergency situations.
Remember to replace them with the jack, so you will have them handy if
needed later.
