Installation: Rear-Facing Installation: Rear-Facing
Lap-Shoulder Belt Installation
Figure A illustrates a rear-facing, lap-shoulder •
belt installation.
When not in use, always store the LATCH •
connectors in the storage slots. See page 29.
Recline the child seat then place it rear-facing 1
on the vehicle seat. This child seat must be in
the recline position when installed rear-facing.
See Recline Adjustment on page 29 .
Lift the cover to open the rear-facing lock-off 2
farthest from where the vehicle belt will be
buckled (Fig. B).
Pull the vehicle belt out, then pass it 3 under the
LATCH bar and through the rear-facing belt
slot (Fig. C).
The vehicle belt can be routed over or under •
the cover.
Route the vehicle belt across seat then 4
through the opposite rear-facing belt slot and
under the LATCH bar.
IMPORTANT: The vehicle belt must rest behind the
child seat buckle strap.
Verify that the vehicle belt is not twisted, 5
position the lap belt portion through the open
lock-off, then buckle (Fig. D).
Push the child seat firmly into the vehicle seat 6
while removing slack first from the lap portion
of the vehicle belt, then the shoulder portion
(Fig. E).
Position the shoulder portion of the vehicle 7
belt through the open lock-off, tighten belt,
close the lock-off arm (Fig. F), and replace the
cover.
The lock-off is properly closed when a click is •
heard.
To prevent damage, never extend the lock-off arm •
beyond its normal open position and always keep
the lock-off closed when it is not in use.
If your vehicle is equipped with an automatic •
locking retractor (ALR), use of lock-offs is not
required as long as the ALR is locked. Check your
vehicle owner’s manual to determine the type of
retractor your vehicle has, and how to lock the
retractor.
Verify that vehicle belt is tight and that the child 8
seat is secure.
The child seat is secure when it cannot be moved •
more than 1 in. (2.5 cm) front-to-back or side-to-
side at the belt path. If the child seat is not secure,
repeat the installation process or use an alternate
seating location.
When properly installed in the rear-facing position, •
the back angle of the child seat should be 30º – 45º
from vertical (not to exceed 45º) when the car is
parked on a level surface (Fig. G).
If necessary, the proper recline angle can be •
achieved by placing a rolled towel or pool noodle in
the vehicle seat bight to level the child seat’s base.
Rear-facing installation can be improved by the •
use of the Versa-Tether. See pages 25 – 28.
