To prevent breakage, never extend the lock-off arm •
beyond its normal open position and always keep
the lock-off closed when not in use.
If your vehicle is equipped with an automatic locking •
retractor (ALR), use of the lock-offs is not required
as long as the ALR is locked. Check your vehicle
owner’s manual to determine what type of retractor
your vehicle has and how to lock the retractor.
Verify that the vehicle belt is tight, locked, and 8
that the child seat is secure.
The child seat is secure when it cannot be moved •
more than 2.5 cm (1 in.) front-to-back or side-to-side at the belt path. If
the child seat is not secure, repeat the procedure 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. F).
If necessary, the proper recline angle can be achieved by placing a rolled •
towel or pool noodle in the crease of the vehicle seat to level the child
seat’s base.
Rear-facing installation can be improved by the use of the Versa-Tether. •
