Convenience Net (Option)
Dual Sun Visors
Each sunvisor has two parts, so that both the windshield
and door glass can be shaded at the same time.
Your vehicle may have a convenience net. You'll see it
just inside the back wall of the trunk.
Put small loads, like grocery bags, behind the net. It can
help keep them from falling over during sharp turns or
quick starts and stops.
The net isn't for larger, heavier loads. Store them in the
trunk as far forward as you can.
You can unhook the net so that it will lie flat when
you're not using it.
