Assembling Your Stroller - Attaching Toddler Seat
1
Before attaching toddler seat to stroller, CHECK to make sure mounts
are in the most upright position.
If mounts are not set to the upright position, you will need to lift the
multi-position recline handle at the top of toddler seat and rotate mounts
as shown.
IMPORTANT: If mounts are not in the most upright position, you will not
be able to properly attach the seat to the stroller mounts.
