Rear-Facing Installation

Lap-Shoulder Belt Installation

Before You Begin:
• Check that your vehicle belt is compatible for use with child
seats. See pages 6 – 8 for more information.
* If your vehicle seat belt system includes a locking feature,
use of the lock-offs is not required as long as the vehicle seat
belt system is locked. Check your vehicle owner's manual to
determine how to lock your vehicle seat belt system when
installing a child restraint.
• Recline this child seat to position 3 and place rear-facing on the
vehicle seat (see page 15).
* When properly installed in the rear-facing
position, the back angle of the child seat
should be at least 30˚ for children and up
to 45˚ from vertical for infants unable to
maintain head and neck control (not to
exceed 45˚) when the car is parked on a
level surface. Use the blue line as a guide
to achieve the proper recline angle for rear-
facing installations. The blue line will be
parallel to the ground when the child seat angle is at the center
of the angle range (30 – 45˚). If necessary, the proper recline
angle can be achieved by placing a rolled towel or pool noodle
in the vehicle seat bight.
• Britax recommends that the Versa-Tether is used at all times.
Using the tether will improve the stability of the child seat and
reduce the risk of injury. Check your vehicle owner's manual for
tether anchor locations. See page 18 for possible rear-facing
tether configurations.
Install with the lap-shoulder belt as shown above.
IMPORTANT:
• The harness buckle strap should lie toward the back of the
child seat during installation.
• The buckle should be in the inner slot for rear-facing
installation.
