HOW TO SETUP
ADJUSTING SHOULDER HARNESS STRAPS HEIGHT
Correct fitment of the harness is very important as it restrains the child in the restraint. The harness
must fit firmly around the upper torso of the child and be positioned so as to leave the child's arms
and legs free.
1. Lower shoulder strap slots.
2. Mid shoulder strap slots.
3. Upper shoulder strap slots.
4. Top slots in seat back
5. Harness slots in headrest.

6. Top slots in headrest
7. Headrest clamp.
8. Shoulder harness straps.
9. Harness tongues & buckle.
10. Lap strap slots.
11. Crotch strap slots.
12. Harness adjustment strap.
13. Shoulder Height Markers.
The shoulder straps must be in the slots which are nearest to the child's
shoulders, but not more than 25mm below the child's shoulders. If
shoulders are above the middle shoulder height marker then the child is
too large for toddler use with the in-built harness and the restraint
must then be converted for child use as a booster seat.
(Booster Seat Mode - see pages 26 onwards).
Note: If child's shoulders touch the headrest side wings,
raise the headrest to the next shoulder strap slot position.

ADJUSTING THE BUCKLE POSITION

The buckle needs to be positioned as shown. If the buckle is too low it will be uncomfortable and
needs to be lengthened. See next page for adjusting to a better position.

IMPORTANT :
You must adjust the crotch strap to the correct length for your child before installing the restraint as
it cannot be adjusted in the car. The crotch strap should only be extended if the harness tongues are
located low against your child's legs, thus creating discomfort.
Always return the crotch strap to its shorter length when using the seat with a smaller child.
The buckle should always be positioned low down on your child's abdomen.
25MM
DO NOT attempt to remove the crotch strap from the adjuster. Adjustment is made by feeding the
crotch strap through the adjuster as shown on the next page and does not need to be removed from
the seat.
Buckle Position
OK
Centre of button on buckle,
level with top of child's
thighs or just above (with
all slack removed from
crotch strap.)
