Forward-Facing
IMPORTANT: In forward-facing installations, it is important that the base of
the child seat rests completely flat on the vehicle seat. As illustrated below,
it is permissible to allow up to 20% or 3 inches (7.6 cm) of the base to hang
over the edge of the vehicle seat. Some vehicle seats do not allow enough
of the child seat base to contact the vehicle seat. If this is the case, adjust
the recline angle to a more upright position. Not doing so could cause the
child seat not to perform as intended.
Acceptable overhang
WARNING:
head restraint can prevent the child seat head pad
from being raised high enough to properly adjust
the harness for the fit of your child when using a
forward facing reclined position. DO NOT force the
child seat head pad past the vehicle head restraint.
Doing so could cause the child seat not to perform
as intended. If the location of the vehicle head
restraint interferes with the child seat head pad,
raise or remove the vehicle head restraint. If the vehicle head restraint
cannot be removed, move the child seat to the upright position or try a
different seating location.
