With this system, use the LATCH system instead of the
vehicle’s safety belts to secure a child restraint.
CAUTION:
If a LATCH - type child restraint isn’t attached to
its anchorage points, the restraint won’t be able
to protect a child sitting there. In a crash, the
child could be seriously injured or killed. Make
sure that a LATCH
- type child restraint is
properly installed using the anchorage points, or
use the vehicle’s safety belts to secure the
restraint. See “Securing a Child Restraint in a
Rear Outside Seat Position” in the Index for
information on how to secure a child restraint in
your vehicle using the vehicle’s safety belts.
