label on each side of the child seat. (Figs. E
and F).

child seat, and that the child seat is stable.
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. H).
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.

adjacent vehicle LATCH anchor (Fig. D) in the
upright position (Fig. C).
An audible click confirms attachment. •
Ensure that the LATCH strap is not twisted. •

strap may be twisted, or there may be debris in the
LATCH connector. Correct either situation before
