Is the LATCH system or the safety belt preferred?
The LATCH system allows you to securely attach your safety seat in your car without using the vehicle belt and possibly to get a better fit. For seating positions with LATCH anchors, experts recommend trying the LATCH installation first and only using the vehicle belt in that seating position if LATCH, for some reason, results in a looser fit. If you want to use the center rear seat and no LATCH anchors are available (check the vehicle owner’s manual), try the vehicle belt to be sure you can get a tight installation. If you cannot, try the LATCH anchors in a different seating position.
