Vehicle Seating Positions

DO NOT place child seat rear-facing
in the front seat of a vehicle with
a passenger air bag. DEATH or
SERIOUS INJURY can occur. See your
vehicle owner's manual for child seat
installation instructions. The back seat
is the safest place for children 12 and
under.
Some vehicles have no seating positions which are
compatible with this child seat. If in doubt, contact the
vehicle manufacturer for assistance.
Forward-facing vehicle seats MUST be used with this
child seat. Side-facing or rear-facing seats CANNOT be
used. See the diagram below.
