Cargo Tie Downs
There are four cargo tie
downs in the rear that allow
you to strap cargo in and
keep it from moving inside
the vehicle.
Luggage Carrier
CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier
-- like paneling, plywood, a mattress, and
so forth -- the wind can catch it as you drive
along. This can cause you to lose control. What
you are carrying could be violently torn off, and
this could cause you or other drivers to have a
collision, and of course damage your vehicle. You
may be able to carry something like this inside.
But, never carry something longer or wider than
the luggage carrier on top of your vehicle.
A luggage carrier allows you to load things on top of
your vehicle. The luggage carrier has slats and side rails
attached to the roof, sliding crossrails and places to use
for tying things down. These let you load some other
things on top of your vehicle, as long as they are not
wider or longer than the luggage carrier.
