Selecting a Vehicle Seating Location

WARNING
There are many different types of vehicles, vehicle seat belt systems, or other occupant restraint systems in use today. Accordingly, this manual can only give guidelines for proper installation in your vehicle. In addition to this manual, you must also read and understand the vehicle owner’s manual, which should address use of child restraints.  f your vehicle owner’s manual does not address the installation of child restraints, please contact your local vehicle dealer, or the vehicle’s manufacturer to obtain this information before using  this Car Seat.
Not every seating location within a vehicle may be safe for the installation of this Car Seat. In fact, some vehicles have no seating location that is safe for the installation of a Car Seat.
Improper placement of this Car Seat within a vehicle will increase the risk of death or serious injury in a sudden stop or crash. See “Vehicle Seat Belts” section for more information on vehicle seat belts.
Please follow the instructions in this manual and in your vehicle owner’s manual carefully to ensure proper location and installation of this Car Seat. If you are uncertain about the proper location of the Car Seat within the vehicle, contact your vehicle manufacturer directly or through their dealer before using this seat. For additional information or assistance contact Baby Trend® at 1-800-328-7363.

6.1 Overall Considerations for Selecting Seating Location

  • Please review your vehicle owner’s manual to determine the best location for each Car Seat use mode, any specific instructions  for Car Seatinstallation, or to determine if any locations are unsafe for Car Seat installation.
    If you do not have the vehicle owner’s manual or the owner’s manual does not address child car seat installation, please contact the vehicle manufacturer to obtain this information  before using the Car Seat.

  • Use rear vehicle seating position whenever possible. According to accident statistics, children are safer when properly restrained in rear vehicle seating positions, rather than front seating positions. Whenever possible, this Car Seat should be secured in the rear center, seating position. The rear center position sometimes is equipped with a vehicle lap belt only and CANNOT be used when this Car Seat is used as a booster seat WITHOUT the Built-in Safety Harness.

  • Only use a vehicle front seating location if specifically allowed in vehicle owner’s manual and following all instructions in the vehicle owner’s manual.baby trend FB49XXXB-S Hybrid SI 3 in 1 Combination Booster Car Seat with Side Impact Protect - Overall Considerations

  • Use a vehicle seating location that has a tether anchor whenever possible.
    Installation with Top Tether is Recommended.
    a. Baby Trend requires using the Top Tether provided with this car seat whenever possible. Installation of a car seat using the Top Tether can make getting a secure installa- tion easier and can reduce the risk of injury in a crash.
    b. The car seat may be installed without the Top Tether when a vehicle tether anchor is not available.

  Lower Anchors and Tethers for Children (LATCH) System is designed to make installation of child car seats easier by requiring child restraints to be installed without using the vehicle’s seat belt system. Since September 1, 2002, at least two rear seating positions of all cars, mini vans and light trucks come equipped with lower child restraint anchor points located between a vehicle’s seat cushion and seat back. These vehicles are also equipped with at least 3 top tether anchorages located behind the vehicle seat. Together, the lower anchors and top tether make up the LATCH system. All child restraints manufactured since September 1, 2002 have lower anchor and top tether attachments which will connect to the vehicle’s LATCH System.
Read your vehicle owner’s manual for exact locations, identifi- cation and requirements for use with a child restraint.
ONLY use LATCH to secure your car seat in a seating position recommended by the vehicle manufacturer for LATCH installation. Refer to the vehicle owner’s manual for the vehicle’s top tether anchor locations. Vehicle anchorages should be identified by one of  the following symbols.baby trend FB49XXXB-S

Accordingly, DO NOT use the Car Seat with this type of Vehicle Seat Belt system.
