MEET YOUR CHILD SEAT MEET YOUR CHILD SEAT

REARWARD FACING-

To be used only in a rearward-facing position until the child's shoulders either reach the lower
shoulder height marker (approximately 12 months of age) or reach the middle height marker
(approximately 2 to 3 years of age).

FORWARD FACING-

Then to be used in a forward-facing position until the child's shoulders reach the upper
shoulder height marker (approximately 4 years of age).

Continue to use this child restraint until the child reaches this limit.

Do not use forward facing until 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.

Children who have outgrown this restraint are safest in a larger child restraint with an in-built
harness or a booster seat until their shoulders reach the upper shoulder height marker of the
restraint.

To ensure that your child gets all the protection designed into the restraint PLEASE READ AND
FOLLOW THESE INSTRUCTIONS EXACTLY and use only Britax Safe-n-Sound recommended
parts and accessories.

If in doubt about the method of installation, consult Britax Childcare or agent, or a child
restraint fitter or, in New Zealand, to consult the agent for the vehicle.

只用于后向式安装，直到婴儿的肩膀达到靠下的肩高标记（大约12个月的宝宝）或者中部的肩高标
记（大约2-3岁的儿童）。然后用于前向式安装，直到儿童的肩膀达到靠上的肩高标记（大约4岁的儿
童）。

在儿童达到该座椅上限以前必须不断使用这一安全座椅。
在儿童肩高未超过靠下的肩高标记之前不得采用前向式坐姿。
婴儿过早乘坐前向式座椅则可能受到严重的伤害。
儿童过早使用垫高椅则可能受到严重的伤害。
个子比该安全座椅大的儿童最安全的做法是乘坐设有内置安全带的更大汽车座椅或垫高椅，直到他们

的肩膀达到该座椅靠上的肩高标记。

THE CLICKTIGHT SYSTEM

The CLICKTIGHT System makes installing your child seat easier in just a few steps. Your
child seat will be safe, secure and remain tightly fixed. It makes it seamless to change it from
rearward to forward facing or move it from one vehicle to install in another.

ADVANCED SIDE IMPACT CUSHION TECHNOLOGY™ (SICT) PROTECTION

WHY DO I NEED ADVANCED SIDE IMPACT CUSHION TECHNOLOGY (SICT)?

In the event of an accident, your child must be optimally protected at any age, especially for
the most common types of accidents, frontal and side collision. With side collisions, children
are at most risk, because compared to a frontal collision, side collisions have less crumple
zone to disperse the energy released during impact.

WHAT IS IT?

Our Advanced SICT – Side Impact Cushion Technology with crumple zone feature is
designed to provide optimum safety to your child in the event of a side impact collision.

HOW DOES IT WORK?

With maximum safety and flexibility in mind, Advanced SICT can be used when the child seat
is positioned next to the vehicle door. When deployed, it is uniquely designed to enhance
protection in the event of a side impact collision. Combined with the energy absorbing
protective shell, Advanced SICT significantly reduces the risk of injury to your child.

THE ACTIVE HEADREST RESTRAINT (AHR)

The Active Headrest Restraint is designed with deeper side wings to shield and protect your
child's head in a side impact crash. The Active Head Restraint has an inner Side Impact
Cushion Technology layer which provides 180 degree protection around your child's head.
The AHR is adjustable to grow with your child and works in conjunction with SICT to protect
your child's head and minimise the force of impact.

CARS WITH FORWARD FACING SEATS.

GENERAL

• Babies and children below 4 years old must not sit in the front seat of a vehicle
unless allowable by the Regional Road Rules. Check your Regional Road Rules.

• Regularly check the restraint components, straps and other fitments for correct
function and condition. If faulty, cease using and seek repair by Britax.

• Protect all webbing from abrasion and cutting by sharp corners and edges.

• The restraint should not be purchased or sold as a second hand item. It is
recommended not to use child restraints older than 10 years as the protection in an
accident may be reduced.

• THIS RESTRAINT IS NOT SUITABLE FOR USE WHERE THE TOP TETHER STRAP
MAY FALL INTO A SPLIT IN THE SEAT BACK OR OFF THE SIDE OF THE SEAT.

• Seatbelt extenders are not recommended to be used if the seatbelt is not long
enough to secure the child restraint. If seatbelts are too short then seek advice from
a child restraint fitter and consider their recommendations before using a seatbelt
extender. If you use a seatbelt extender then ensure that the seatbelt buckle does
not enter the rearward or forward facing belt paths.

• A rear facing child restraint should not be used in the front seat if a passenger airbag
is fitted and cannot be disabled.

• Rearward and forward facing child restraints should always be correctly installed,
properly adjusted and used as instructed by the manufacturer instructions.

• Ensure babies and toddlers are adequately shaded from direct sunlight through side
or rear windows.

• Check the car is ventilated by opening windows or using the car's ventilation system
taking in external air. Recirculation setting is not suitable for providing ventilation.

• THIS RESTRAINT MUST BE ATTACHED TO A CHILD RESTRAINT UPPER
ANCHORAGE POINT IN THE CAR. REFER TO CAR OWNER'S HANDBOOK FOR
LOCATION OF UPPER ANCHORAGE POINTS. REFER TO A CHILD RESTRAINT
FITTING STATION IF NO UPPER ANCHORAGE POINTS ARE IN THE MOTOR CAR.
Refer to pages 69 to 73.
