The LATCH system can only be used in vehicles that already have the anchor bars installed in the vehicle seat curve. These anchor bars cannot be reconstructed into the vehicle. Refer to your vehicle owner's manual to see which seating positions may be equipped with the LATCH system. The car seat is used with the LATCH system the same way as it is with the vehicle seat belt. The LATCH system does not, for example, allow an infant to be placed rear-facing in the front passenger seat with an active air bag. Please refer to your instruction manual for specific installation instructions.
