7 Position the vehicle belt through the
rear-facing lock-off farthest from the
vehicle buckle, then close lock-off arm
(Fig. D) .
• Lock-off is properly closed when a positive
click is heard.
• To prevent breakage, never bend the lock-
off arm up or down.
8 Verify that the vehicle belt is tight and
the child restraint is stable .
NOTE:
• The back angle of the child restraint should not exceed 45º when
properly installed in the rear-facing position .
• Installation can be improved by the use of the Versa-Tether
(see pages 23–25) . The recline angle can be adjusted by
tightening the tether as described on page 24, using anchor
point 3 .
• If there is a problem stabilizing the child restraint, place a rolled
towel in the crease of the vehicle seat to help level the child
restraint base .
WARNING: DO NOT raise the base beyond horizontal or off of the
vehicle seat; doing so will reduce the protection for the child .
Removal
