If you put things inside your vehicle — like suitcases,
tools, packages, or anything else — they will go as fast
as the vehicle goes. If you have to stop or turn
quickly, or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the trunk or rear area of your
vehicle. In a trunk, put them as far forward
as you can. Try to spread the weight
evenly. If you have fold-down rear seats,
you will nd four anchors on the back wall
of your trunk. You can use these anchors
to tie down lighter loads. They are not
strong enough for heavy things, however,
so put them as far forward as you can in
the trunk or rear area.
CAUTION: (Continued)
CAUTION: (Continued)

Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.
