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.

Use the blue line as a guide to achieve the proper recline angle for rearfacing 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.
