The Maxi Rider AHR™Easy Adjust™is suitable for toddlers and older children as a convertible booster

seat. This child restraint is tted with our exclusive VERSA

TETHER™ 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 in-built 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.
WHEN USED WITH IN-BUILT HARNESS - TO BE USED WITH A LAP-SASH OR LAP ONLY SEAT BELT IN
THE BACK OF MOST CARS WITH FORWARD FACING SEATS.

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.

child harness.

• The lap part of the seat belt must be rmly across the thighs and the sash straps tted diagonally

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.

GENERAL WARNINGS - also see warnings on pages 12 and 27.

• THIS RESTRAINT IS NOT SUITABLE FOR USE WHERE THE ANCHORAGE STRAP MAY FALL INTO A
SPLIT IN THE SEAT BACK (E.G. HATCHBACK OR WAGON).

reach this marker, convert the

child restraint to booster seat

mode and use either a lap-sash

seat belt or a child harness and

lap-sash seat belt or lap only

INSTALLATION AND USE OF RESTRAINT

For Toddlers who have reached the shoulder height limit on their infant restraint refer to pages 10-24.
For Children who have reached the shoulder height marker and need to use a booster seat refer to

Pages 25-52.

HOW TO SET-UP

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

support their head. Britax recommends that you keep your child in a rearward facing restraint for as
long as possible (up to approx 12 months).

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™ Converter is stored in the recess under the cover when the seat is
used in Toddler mode, to avoid injury or discomfort.

ADJUSTING SHOULDER HARNESS STRAPS HEIGHT

Correct tment of the harness is very impor tant as it restrains
the child in the restraint. The harness must t rmly around the

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 25 onwards).

ADJUSTING AHR EASY ADJUST HEADREST AND
HARNESS STRAP HEIGHT

A. Loosen the harness straps before adjusting the headrest.

B. You do not need to remove the restraint from the vehicle to

maybe done with the child in the seat, the child will need to
lean forward to allow the headrest to be adjusted.

C. To adjust the headrest, gently lift the lever at the top of the

headrest then pull up or push down so that the shoulder
strap slots are level with or slightly above your child’s

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 correct length when using the seat with a smaller child.
The buckle should always be positioned low down on your child's abdomen.

ADJUSTING THE BUCKLE POSITION

The Child restraint is supplied with the crotch straps
set at the correct position for use with the in-built

harness.

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.

IMPORTANT :

ADJUSTING THE CROTCH BUCKLE HEIGHT

The crotch buckle height is adjusted by threading the 3 bar
anchor plates into extra slots to shorten the buckle height. The
seat has the crotch straps tted in position when supplied.
Position 1 is generally used with the in-built harness or toddler

mode.
