DUO plus child seat
Function of the buckle
The function of the buckle is very important
for the safety of your child. Functional faults
relating to the buckle are mostly attributa-
ble to accumulations of dust and dirt.
Functional Problem
• The buckle tongues are only slowly
ejected when the red release button is
pressed.
• The tongues will no longer engage (are
ejected again).
• The buckle tongues engage without the
audible "click".
• The tongues are difficult to insert (you
feel resistance).
• The buckle only opens after applying
extreme force.

1. Remove the crotch belt 20.
2. Open buckle 17 by pushing the red re-
lease button 18. Loosen the harness
(see Buckling up the child page 49).
Open Velcro on crotch belt pad 21 and
take off. Put the seat shell into the

Push it upright through the belt
slot 22.

4. Soak the buckle 17 in warm water
(with washing-up liquid) for an hour at
least. Rinse and dry thoroughly.

6. Holding the metal plate upright, push
it from above down through the belt
slot 22 in the cover and into the seat
shell. Check for secure fitting by vigor-
ously pulling the crotch belt 20.
Feed the Velcro of the crotch belt
pad 21 into the crotch belt 20 and
close.
