4-2 Storage The back of the console has a cupholder that folds down for the rear seat passenger to use. Luggage/Load Locations Cargo Area All-Weather Cargo Area The vehicle's cargo area can be used in many different configurations - cargo panels on or off, Midgate up or down, rear glass in or out. It has features that resist the elements and protect cargo. It is designed to quickly direct water out of the cargo box. The top drain grates, side rail channels, catch cups, Midgate drain, cargo area floor drains, and rubber cargo mat help do this. Top-Box Storage Even when all of these things are working properly and the cover system is on, there may be some instances (heavy rains, automated car washes, etc.) when water can collect in the following areas: A. Top drain grates B. Removable front drain grate (Midgate drain grate) C. Side rail channels and catch cups There are top-box storage units on both sides of the rear cargo area. The passenger side contains the tire changing tools. To lock or unlock, use the key then press the key cylinder to open.
