Installation: Rear-Facing
Lap-Belt Installation
• Figure A illustrates a typical rear-facing
lap-belt installation.
• When not in use, always store LATCH
connectors in storage pouches sewn in
cover above rear-facing lock-offs.
Place the child restraint rear facing and
in full recline position on the vehicle
seat .
Lift cover to access rear-facing lock-off
farthest from where the vehicle belt will
be buckled (Fig. B) . Open lock-off .
Pull the vehicle belt out, then pass it
through the closest rear-facing belt slot
(Fig. C) .
• The vehicle belt can be routed over or
under the restraint cover.
Route vehicle belt behind and under the
buckle strap, then through the second
rear-facing belt slot .
Verify that the vehicle belt is not
twisted, then buckle (Fig. D) .
Push the child restraint firmly into the
vehicle seat while removing slack from
the vehicle belt .
Position the vehicle belt through the
rear-facing lock-off farthest from the
vehicle buckle, then close lock-off
arm (Fig. E) and replace cover .
• Lock-off is properly closed when a positive click
is heard.
• To prevent breakage, never extend the lock-off
arm beyond its natural open position and always
keep lock-off closed when not in use.

Installation: Rear-Facing
If your vehicle is equipped with an automatic
locking retractor (ALR), use of lock-offs is not
required as long as the ALR is activated. Check
your vehicle’s owner’s manual to determine the
type of retractor your vehicle has.
Verify that the vehicle belt is tight
and the child restraint is stable . The
restraint is stable when it cannot be
moved front to back or side to side
more than 1 inch (2 .5 cm .) at the
belt path .
NOTE:
When properly installed in the rear-facing
position, the back angle of the child restraint
should be 30 º-45º from vertical ( not to
exceed 45º from vertical) when the car is
parked on a level surface.
The rear-facing installation is always
improved by the use of the Versa-Tether®.
(See pages 23-25.)
The proper recline angle can be achieved by
placing a rolled towel or pool noodle in the
crease of the vehicle seat to help level the child restraint's base.
If there is a problem stabilizing the child restraint, tighten the tether as
described on page 24, using anchor point 3.
WARNING: DO NOT raise the base beyond horizontal or off of
the vehicle seat; doing so will reduce the protection for the child
and may damage the recline adjustment .
Removal
Release Versa-Tether, if used, then reverse above directions .
