Booster Mode
WARNING!
• Position forward-facing only in a seating position with a
lap-shoulder belt.
• Use only the vehicle's lap and shoulder belt system when
securing a child in booster mode. Never secure a child
with a lap belt only in booster mode.
• Always secure the unoccupied child seat.
• If the lower anchors in your vehicle prevent proper vehicle
belt fit across your child you cannot use LATCH to position
this seat in booster mode. See below.
The vehicle belt fits properly
when the lap part sits low across
the child's upper thighs (b) and
the shoulder part lies across the
center of the child's chest and
does not contact the child's neck
when routed through the upper
belt guide (a).
• This child seat can be used in
booster mode with children who
weigh between 40 and 110 lbs
(18.1 and 49.9 kg) and stand
between 45 and 62 in. (114.3
and 157.5 cm) in height. BRITAX
recommends using booster mode
only once your child has outgrown
harness mode.
• This child seat cannot be in the
recline position when used in
booster mode.
• In booster mode, this child seat can
be positioned on the vehicle seat
using the LATCH system. Use the
vehicle's lap-shoulder belt to secure
the child. Ensure that the LATCH
system does not interfere with the
vehicle belt function and
alignment when securing your child.
