A: Thanks for your interest in our Nautilus 2.0 LX 3-in-1 Harness Booster Car Seat! You can install the 5-point harness mode with the vehicle's seat belt rather then the included latches. When in the high-back and no-back booster modes the vehicle's seat belt should be used to secure your child into the seat. In the booster modes you can use the latch system up to 100lb but it is not required we do recommend to make sure that the seat is secured no matter what when the seat is not in use. Hopefully this helps! - The Graco Team
