With this system, use the LATCH system instead of the
vehicle's safety belts to secure a child restraint.
1-84
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
is properly installed using the anchorage points,
or use the vehicle's safety belts to secure the
restraint. See "Securing a Child Restraint in
the 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.
