Using With the Base
Before installing the infant car seat:
• Check that your vehicle seat belt is compatible with
the infant car seat by referring to your vehicle owner's
manual and page 41 in this user guide�
Overhang
It is important that the base of
the child seat rests completely
flat on the vehicle seat with no
side overhang� As seen in the
illustration, it is permissible to
allow up to 3 in� (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, choose another seating
position� Failure to do so could
cause the child seat to not
perform as intended�

Vehicle must be
parked on a level surface�

2� Move the base up or down
until the red marker is
visible between the two
lines on the recline angle
indicators while on the
vehicle seat�
If there is a problem achieving the proper recline angle after
installing, try another approved seating position in your
vehicle or:
a� Uninstall the base and lower the recline angle
adjustment foot so that the recline foot is not
extended�
b� Remove the base from
the vehicle and place
a rolled towel or pool
noodle in the vehicle
seat bight�
c� Place the base against the towel or pool
noodle to level the shell and install�
NOTE: If a towel or pool noodle is needed for the
recline angle, the recline angle adjustment foot on
the base should remain in its lowest position.
IMPORTANT:
After the child is secured in the infant car
seat and the car seat is attached to the base, ensure that
the red marker is visible between the two lines on the
recline angle indicator�
