Lap Belt Installation
Before You Begin:
• Check that your vehicle belt is compatible for use with child
seats. See pages 8 – 13 for more information.
• 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.
