What is ISOFIX?
ISOFIX is an international standardized fitting system, which provides the safest, easiest and quickest way to install a child car seat correctly without the need of vehicle seat belts. The name ISOFIX stands for ISO (International Standardization Organization) plus FIX (Fixation). ISOFIX car seats make use of two standard attachment points located at the base of the seat, plus an anti-tipping forward device: either a support leg or top tether. From 2006 all new cars are equipped with ISOFIX, and ISOFIX is also fitted in a large number of car brands built prior to 2006.
My child climbs out of the safety harness, what can I do?
The same principle applies to all car seats and means that your child cannot create extra space if there is no extra space to begin with. Some children have shown us that, with only a minimum of slack in the belt system, they can get a hand between the buckle and their stomach and then, by moving it towards their head, they can get an elbow under the belts – but this requires a very flexible shoulder. These children display a tremendous desire to free themselves from their car seat. Child safety in the car and freedom of movement are not compatible in principle. To transport a child not only safely but also comfortably, a slight amount of slack in the belt system is needed. If the belt is pulled extremely tightly and the child is sitting calmly in the car seat, experience has taught us that all car seats are the same when it comes to 'climbing out of the car seat'. We see a similar pattern in children ages 1-4 years in car seats of various types and from various manufacturers. The belt system is a closed system that keeps the child in the same position continuously - during normal car trips as well as during a sudden stop or accident. This system is closed by securing the child when tightening the belts. If this is done properly, the belts cannot be loosened during use (if this does happen, we ask that you contact our Customer Care team through the contact form on our website)
The AxissFix Plus complies with i-Size (R129) regulation. What does that mean ?
i-Size (R129) is a new European regulation, active from July 2013, that aims at increasing children safety in car by supporting rearward facing travelling up to at least 15 months, promoting universal ISOFIX installation, and improving safety standards for additional protection for head and neck. Find out more about i-Size
Why is the classification on the AxissFix Plus in length and not in weight?
The Maxi-Cosi AxissFix Plus complies with the new i-Size (R129) regulation, and this change is part of i-Size. It is done in order to make it easier for parents to choose the right car seat for their child, and thereby minimize premature up-sizing of the car seat. The size will now be the new reference to choose the correct car seat. Nevertheless, weight are still taken in account as i-Size regulation also mentions that weight of the car seat + weight of the child should not overtake 33kg. Consequently, the AxissFix Plus is suitable baby and toddlers from 45 to 105cm length, and maximum 19kg weight.
Will the AxissFix Plus fit in my car?
The AxissFix Plus is an i-Size car seat. It is approved to the regulation R129, and fits in most of the vehicles equipped with ISOFIX with Top Tether, and on all i-Size compatible vehicle seating positions. We invite you to check in your car instruction manual if your car is equipped with 3 point ISOFIX (2 Isofix anchorages and 1 Top Tether) or consult our online Car Fitting List.
I don’t find my car in the car fitting list, does it mean the AxissFix Plus can't fit in my car?
The Car Fitting List is a non-exhaustive list of cars in which the AxissFix Plus can be installed. This list is regularly updated on our website. In the case you don't find your car, it can mean that the fitting test with your car has not be done yet. Then, we invite you to check the instructions in your vehicle’s manual, and contact our Customer Care team to check if AxissFix Plus can fit your car.
Can I also install the AxissFix Plus using the car’s seat belt?
The AxissFix Plus is an i-Size car seat that can be installed only by using ISOFIX system with Top Tether. It can’t be installed using the car’s seat belt.
Can I install the AxissFix Plus on the front passenger seat?
Yes if the car has ISOFIX anchor points on the front seat.  When you use the AxissFix Plus rearward facing it is important to always deactivate the airbag. When you use the AxissFix Plus forward facing we recommend to deactivate the airbag or placing the front passenger seat in the rearmost position. Most cars, however, don’t have ISOFIX anchor points on the front passenger seat. This means that it is often not possible to install the car seat on the passenger seat.  We invite you to check in your vehicle’s manual or in our Car Fitting List if the AxissFix Plus can be installed in the front passenger seat. If you plan to install AxissFix Plus in forward-facing position, in front passenger seat, you need to check the legislation in force in the country where the seat will be used. There is some restrictions depending on countries.
How can I be sure the AxissFix Plus is correctly installed in my car?
To ensure a correct installation, you need to follow the steps defined in the instruction manual. Indicators on the ISOFIX base connectors and Top Tether will confirm correct installation. When ISOFIX buttons become green, it means that the ISOFIX base is correctly connected to the car, and when Top Tether indicator becomes green, the Top Tether is correctly tensioned. We strongly recommend you always check these 3 indicators each time before driving. Watch the installation video for further instructions
How can I be sure the AxissFix Plus is locked in the correct travelling position?
The AxissFix Plus has 2 travelling positions: Rearward facing (from 45 - 87cm / approx. 4m - 2y) and forward facing (76 - 105cm />15m - approx. 4y). Before installing your baby or toddler in the seat, the first step is to select the correct travelling position in the central dash board, depending on your child's size/age. Then, you will be able to swivel the seat from facing you to the selected travelling position. Once the travelling position is locked, you will not be able to swivel the seat in the wrong direction unless you change the selection in the dash board again. This will avoid possible mistake in daily life. The handles will close, and a "clack” can be heard to confirm the seat is locked in the travelling position.
How long can I place my toddler rearward-facing in the AxissFix/AxissFix Plus?
The Maxi-Cosi AxissFix/AxissFix Plus should be used rearward-facing up to a minimum age of 15 months to guarantee optimum safety for your child. Maxi-Cosi recommends you to use the seat in the rearward facing position for as long as possible and up to the limit defined (until 87 cm or approx. 2 years). This will significantly improve the protection of the head and neck of the toddler, which is still very fragile at this age.
Why there is a measuring scale (blue/red label) on the AxissFix Plus cover and how do I read it?
This print is an informative label to help you to know when it is allowed to switch from rearward facing to forward facing according to the length of your baby or toddler. On a daily basis, it's not easy to know the exact length of your growing baby, and you may want to quickly install your child in a forward facing position because it's easier to see your child. Nevertheless, your child should not be placed in forward facing position before 76 cm or 15 months of age. The goal of this label is clearly to avoid babies to be installed too early in a forward facing position.
How do I switch the AxissFix Plus from rearward to forward facing?
To switch from rearward to forward facing, you need to select the forward facing position in the central dash board, and swivel the seat to the forward facing position. Once the position is selected, you will be able to only swivel the seat from facing you to travelling position to avoid any mistake of installation in daily use.
How do I swivel the AxissFix Plus ?
To swivel the AxissFix Plus from traveling position (rearward or forward facing) to facing you, you only need to pull the handle side of the door to unlock the seat position (no need to use the 2 handles) and swivel the seat facing you. When you want to swivel the seat from facing you to the traveling position, then you only need to swivel the seat itself (no need to use the handle in this case).
A swivelling seat is very convenient but I'm wondering if the AxissFix Plus can come off from its base in case of accidents?
The AxissFix Plus is the successor of the successful Axiss car seat, which has proven over the past 7 years that it’s a reliable and safe car seat.  It took a couple of years of R&D research, crash simulation, and a lot of real crash tests performed before launching this new AxissFix Plus car seat. Because it's a 360° swiveling seat, the mechanism has been intensively tested in all configurations to resist to strong forces, and provide a very high level of safety, requested by the new i-Size (R129) regulation. No fear, the AxissFix Plus car seat is a state-of-the-art safety car seat, answering to the high demanding safety criteria defined by the new regulation, and benefits from all the expertise of Maxi-Cosi.

Can the anti-slip shoulder pads material be painful for child during the Summer?

This material has been selected for this high performance restraint criteria, but also because it’s soft and not painful for the child no matter the temperature in the car.

Can I install a play chain in the Automatic Safety Belt (A.S.B) ?
When the AxissFix Plus is installed in rearward-facing, the Automatic Safety Belt is going across, opposite to the door, and is connecting the top of the base to the top of the seat. On this belt, you can attach a soft play chain to entertain the child during the travel. It will not affect the safety as this belt is equipped with a belt winder. Please remove the play chain or the toy before swiveling the seat as it main interfere with the rotation.
Can I use the AxissFix Plus newborn inlay in the AxissFix?
This is not allowed. The AxissFix Plus newborn inlay has been configured and homologated for use with the AxissFix Plus only, ensuring a safe use of the AxissFix Plus from birth (45 cm). Using the AxissFix Plus newborn inlay in the AxissFix will make the seat uncompliant with the stringent i-Size (R129) safety requirements.
