people in a sudden stop or
turn, or in a crash. .
Put things in the cargo

inside the vehicle so that
some of them are above
the tops of the seats. .
Do not leave an
unsecured child restraint
in the vehicle.
(Continued) Warning (Continued) .
When you carry something
inside the vehicle, secure
it whenever you can. .
Do not leave a seat folded

across the width of the pickup
box. The planks must be
inserted in the pickup box
depressions.
