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.
