Removing the Rear (Suburban Third Seat) If your vehicle has a rear seat, it can be taken out for more cargo space. Before removing the seat, unlatch the outside passenger position safety belts from the seat frame. Then, hang the latch plate end of the belt on the hook at the top of the retractor cover, out of the way. To unlatch the safety belt, press the tip 0f.a key into the release hole of the safety belt attachment while pulling up on the safety belt. To remove the seat, fully open the rear load doors and enter the back of the vehicle.
