JJ Cole bundleme Series Owner's Manual page 6

Now that the Bundleme is
installed at the correct height,
attach the top elastic strap
around the back elastic strap to
keep bundleme in place. Do
not attach so tightly that the
Bundleme is pulled out of
place. If the elastic straps do
not fit around your car seat or
stroller, you may fasten them
securely to each other and
place them behind the
bundleme. Do not place them
within reach of the child.
Place child in seat as usual,
ensuring no gaps between
the back of bundleme and
car seat or stroller, and the
safety straps are positioned
correctly. Fasten safety
harness according to
manufacturer instructions.
Zip up and go!
