Cargo Tie Downs
130
The tire tie-down straps are designed to secure a
flat tire. You can also use the straps and hooks
to secure your luggage.
There are eight tie-down hooks located in the rear
of the vehicle. The straps are located under the
cargo area floor panel. To use the straps, hook the
ends to the lower tie-down hooks in a criss-cross
pattern across the cargo. Pull on the straps at
the buckle to tighten the straps as needed.
