- Smart Cargo Storage: Optimizing the cargo area is made easier with floor-mounted tie-downs, side cargo nets, a grocery bag hook, and a 12-volt power outlet. You’ll never struggle to fish the keys out of your pockets with hands full of groceries, as HANDS-FREE ACCESS® will open the power liftgate hands-free!
