Before purchase

Will this car seat fit in my vehicle?

It is important to check whether the car seat is compatible with your vehicle before you purchase it. The child car seat can be installed on any vehicle seat with the ISOFIX locking arms stored, by using a 3-point automatic belt. The installation with ISOFIX is not possible in all vehicles. Please check whether the installation is allowed on the typelist included with the car seat or our Car Compatibility Checker on the CYBEX Website. If your vehicle is not listed, please contact our Customer Service team.

General

Can I use this car seat on a flight?

No, this car seat is not approved for use on an airplane.

Is it normal that the car seat’s backrest moves, and there is space between vehicle seat and car seat?

Yes, the backrest is adjustable. Therefore it can adapt perfectly to any vehicle seat. In the event of an accident, the backrest moves slightly forward with your child, and is therefore able to secure the whole body early on.

Is it ok to keep using a car seat after an accident?

We at CYBEX strongly recommend that you replace a car seat after any kind of accident. This is because tiny hairline cracks, which may not be visible to the naked eye, can appear in the plastic parts of a car seat after an accident. These cracks can pose an increased risk to safety.

My car seat is faulty, how can I get it repaired?

Please refer to the retailer where you bought your CYBEX car seat. They will deal with the matter on your behalf.

How do I correctly secure my child in the seat?

Please observe the instructions in the User Guide. Adjust the child car seat to the size of your child and make sure that he or she is properly strapped in to ensure maximum safety.

Is it okay to install this car seat on the passenger seat?

We generally recommend using the car seat on one of the back seats of the vehicle. Statistically, installing the car seat on the passenger seat poses a higher risk of injury for your child. However, in exceptional cases the car seat may be used on the passenger seat as well. Please note the following: if the car is equipped with an airbag, put the passenger seat as far back as possible. Please ensure that the upper belt point of the 3-point vehicle belt always stays behind the belt routing of the car seat, so that the belt runs backwards and not forwards. To find out whether a specific CYBEX car seat can be installed on the passenger seat, please use the Car Compatibility Tool on the CYBEX website.

Is it possible to use a car seat with an ISOFIX System in a vehicle without ISOFIX anchorage points?

While this CYBEX car seat is equipped with an ISOFIX System, it can also be installed in vehicles without ISOFIX anchorage points by turning the ISOFIX locking arms 180° inwards and sliding them into the booster seat. Both the child and the car seat can then be secured using only the 3-point vehicle belt.

How can I clean my car seat?

Car seats can be cleaned using a vacuum cleaner or damp cloth. Sand or other dirt beneath the cover can also be removed in this way. To clean the plastic parts, wipe them with a cloth using a mild detergent and warm water. (Warning: Please do not use chemical detergents or bleaching agents under any circumstances). The cover can be washed in a washing machine at 30°C (86°F), using a delicate program and without detergent to avoid any discoloring and wash it separately from other laundry. Do not tumble dry or dry in direct sunlight.

How to take off the seat cover?

The seat cover comprises of three separate parts: To remove the first, unclip the press-stud on the rear of the headrest and the two press-studs underneath the side wings. Position the reclining headrest all the way forward and then separate the Velcro straps behind the headrest. Take off the elastic band that goes around the height adjustment handle. To take off the second cover, remove the backrest from the booster seat. Then pull the two elastic bands at the top to the side and pull the cover downwards. For the third part, unclip the two press studs underneath the booster seat, as well as the two press studs and the elastic band on the back. To reattach the covers, just reverse the above process.

Where can I get replacement parts for my product?

You can order replacement parts from a specialist retailer near you or contact our customer service. To find a store near you, simply go to the Store Locator on the CYBEX Website.   

Installation and Securing your child

How should the headrest be adjusted?

Only a headrest adjusted to the optimum height will give your child the best possible protection and comfort. The height can be adjusted to various positions. The headrest must be adjusted so there is no more than 2 cm between the child’s shoulders and the bottom of the headrest.

Can I use the car seat on laterally-facing vehicle seats?

It is not permitted to use the car seat on laterally-facing vehicle seats.

Can I use the car seat on rear-facing vehicle benches (e.g. in vans or minibuses)?

Yes. You can use this car seat on rear-facing vehicle benches as long as the vehicle bench is approved for use by adults and has a 3-point vehicle belt. The headrest of the vehicle bench should not be removed when fitting on a rear-facing seat.

The ISOFIX System is impossible or very difficult to release from the ISOFIX anchorage points in the vehicle. What can I do?

Sometimes the ISOFIX System may be difficult to release from the anchorage points. Please increase the distance between the car seat and the vehicle seat by releasing the ISOFIX using the adjustment buttons and pulling the car seat away from the vehicle seat. By following these steps, you will release any tension from the System which should help with the de-installation.

Where should I install a car seat in my car?

Although it may be possible to install a CYBEX car seat on other seats in the vehicle, the safest place for a car seat is in the rear seat, behind the front passenger seat. We advise you to refer to the Car Compatibility Tool on the CYBEX Website. You can scan the dedicated QR-Code on your Quick Start Guide or use the specific weblink, provided on the Packaging Box, to access the Car Compatibility Tool for your product.

Safe Travel

Can I use the car seat even when the side airbag is activated?

Yes, the side airbag can remain activated when using the car seat.

Do high-back booster seats perform better than booster seats?

When compared to booster seats, high-back booster seats considerably reduce the risk of injury. Booster seats do not provide proper protection from side-impacts, whereas a high-back booster seat is equipped with side protection. This protects the child from injury in the case of a side collision. High-back booster seats also include a shoulder belt routing which can be adjusted to the height of the child, further improving their travelling safety.

What's the difference between UN R44 and UN R129?

To simplify the process of choosing the right car seat, regulations and norms have been implemented to guarantee general safety standards worldwide. In most parts of the world including Europe, the UN R44/04 and UN R129 testing standards are in effect. R44 classifies child restraints (car seats) according to the weight of the child. However, children grow in different ways. For example, a child might be within the weight range of an R44 seat but their head may already be reaching above the top of the seat. On the other hand, R129 child restraints are classified according to the height of the child, and also specify a weight limit. This is intended to give parents more confidence that a child restraint will fit a child during a specific growth period. The aim of R129 is to make child restraints easier to install, to incorporate side impact testing to provide better protection from side crashes and to keep children in a rear-facing position up until they are at least 15 months old. It also aims to make child restraints more compatible with vehicle seats.

When does a car seat expire?

As soon as a car seat is installed in a vehicle, it may be exposed to high temperatures and high levels of light intensity. As a result, even high-quality and extremely age-resistant plastics such as those used by CYBEX can display certain age-related alterations. To ensure the safety of your child, we strongly recommend that the seats are not used for longer than the prescribed usage periods. A car seat will be designed to keep your child safe for a specific period in their development, for example from birth to approximately 4 years old for a Sirona Series seat. Sometimes they can be used for longer, for example our products for babies and toddlers can also be used for a sibling. To find out the approximate lifespan of your CYBEX car seat, refer to the User Guide or contact our Customer Service.

Usage

What kind of clothing should my child wear when seated in the car seat?

Thick clothing prevents the harness/vehicle belt or impact shield from lying tight against the body of the child. Only a correctly adjusted restraint system can offer maximum protection. For this reason, your child should wear everyday clothing. Thick clothing such as winter jackets and clothing with hoods (e.g. hoodies) as well as hats should be avoided where possible. Once your child has been positioned in the car seat, he/she can be covered with an extra blanket for warmth.

Functionality

What are the two main positions for the reclining headrest?

The reclining headrest is a passive safety feature from CYBEX. If your child is awake, you can set the recline angle of the headrest to the upright position and when they are asleep, you can set the angle to the reclined position. This prevents the child’s head from tipping forward into a vulnerable position while sleeping and keeping it up to seven times safer.
