Lap-Shoulder Belt Installation
Before You Begin:
• Check that your vehicle belt is compatible for use with
child seats. See pages 8 – 13 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.
• This child seat must be reclined to position 3 and placed
rear-facing on the vehicle seat.
* 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 27 for possible rear-facing
tether configurations.
