The Maxi Rider AHR is suitable for toddlers and older children as a convertible booster seat.
This child restraint is tted with our exclusive VERSATETHER™ Catch that allows it to use the
Safe-n-Sound™Protecta PLUS™ child harness in booster seat mode for older children.

To be used in forward-facing position with built-in harness by children whose shoulders are above the
lower shoulder height marker (approximately 6 months of age) until their shoulders reach the middle
shoulder height marker (approximately 4 years of age). Then to be used with either a lap-sash seatbelt
or an add-on accessory child harness until their shoulders reach the upper shoulder height marker
(approximately 6 to 8 years of age).

Continue to use this child restraint until the child reaches this limit. Children are safest in a booster seat
until their shoulders reach the upper shoulder height marker of the booster seat.

Do not use this restraint until child’s shoulders are above the lower shoulder height marker.
Just using a seatbelt is not recommended for children that have outgrown this seat. Use a larger

booster.

THE BACK OF MOST CARS WITH FORWARD FACING SEATS.
WHEN USED AS A BOOSTER SEAT - THIS RESTRAINT MUST BE USED IN CARS WITH FORWARD

FACING SEATS WITH A LAP-SASH SEAT BELT OR WITH A SEAT BELT AND CHILD HARNESS. When
using a child harness with the seat it may be used in seating positions with either a lap or lap-sash
seat belt.

across the chest and on the shoulder.

• If used with a child harness, the lap strap of the seat belt must be adjusted rmly rst and then the

harness, so that the lap strap is not lifted off the child’s lap when the harness is adjusted.

• Do not use with the integral harness when in booster mode. This built in harness must be stored.

• Use only with a lap-sash seat belt or with an add-on accessory child harness and either a lap or

lap-sash seat belt.

INSTALLATION AND USE OF RESTRAINT

For Toddlers who have reached the shoulder height limit on their infant

restraint refer to pages 10-25.

For Children who have reached the shoulder height marker and need to

use a booster seat refer to Pages 26-52.

HOW TO USE THE HEADREST

First remove both harness straps (Refer to page 17). Then rotate lever
down to loosen headrest clamp (A). Slide the headrest up or down
to suit the height of your child, (refer to pages 17-18 for toddler use
or page 32 for child use). In toddler mode, move the headrest so
that the bottom slots in the headrest line up with the top of the child's
shoulders. Then move the headrest so that the slots line up with the
nearest slots in the shell. Ensure that the shoulder slots are correctly
aligned with the shoulders otherwise, move up to the next set of slots
in the shell. Rotate the lever upward to tighten the headrest clamp (B).

Then ret both harness straps, ensuring that there are no twists and

that each strap is in the correct and matching slots in both the seat
shell and headrest (Refer to page 14).

HOW TO SETUP

TO BE USED WITH A LAP SASH OR LAP ONLY SEAT BELT IN THE BACK OF MOST CARS WITH
FORWARD-FACING SEATS.

To be used in forward-facing position by children whose shoulders are above the lower shoulder
height marker (approximately 6 months of age) until their shoulders reach the upper shoulder height
marker (approximately 4 years of age).

Continue to use this infant restraint until the child reaches this limit.
Do not use this restraint until the child’s shoulders are above the lower shoulder height marker.
Infants are at risk of serious injury if they face forward too early.
Children are at risk of serious injury if they move to booster seats too early.
The child should not sit in this forward facing child restraint until their neck muscles are able to sup-

port their head. Stay in a rear facing child restraint.
Regional Road Rules may prohibit the use of this restraint in the front seat until the child is 4 years of

age. Check your Regional Rules for exemptions.

• Fit the restraint rmly to the car seat and then t the harness rmly to the child.

• A loose restraint or harness is dangerous.

• Do not use in a front seat, unless it has a child restraint anchorage point i.e.: utilities.

• Do not use the restraint without the Upper Anchorage Strap correctly attached.

• Do not use on any vehicle seat which faces sideways or rearwards.

• WHERE AN AIRBAG IS FITTED IN THE SEATING POSITION WHERE THE CHILD RESTRAINT IS TO
BE FITTED, FOLLOW THE VEHICLE MANUFACTURERS WARNINGS AND INSTRUCTIONS.

• Always use lap or lap-sash seat belt and upper anchorage strap to attach the child restraint to the

vehicle seat.

• Ensure that the SLIDEGUARD™ clip is stored in the recess under the cover when the seat is used in
Toddler mode, to avoid injury or discomfort.

HOW TO SETUP

HOW TO SETUP

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.
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.

SETTING UP THE HARNESS

A. Sit the restraint on a at ground and supported from behind so that it will not tip over.
B. Get the child to sit comfortably in position.
C. Determine the desired shoulder strap position.
D. Remove the child and adjust the shoulder straps using the following methods.
E. Repeat steps A-C to conrm the correct set-up of the built-in harness.

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.

ADJUSTING SHOULDER HARNESS STRAPS HEIGHT

Centre of button on buckle,
level with top of child's
thighs or just above (with
all slack removed from
crotch strap.)

Correct tment of the harness is very impor tant as it restrains the child in the restraint. The harness
must t rmly around the upper torso of the child and be positioned so as to leave the child’s arms

and legs free.

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.
