Before purchase

How do I know if my car seat is suitable for an aircraft?

You can determine if your car seat is aircraft approved if it has the TÜV Rheinland seal with the reference “For Use in Aircraft”. Car seats with this seal are specifically tested for safety and use with a two-point harness system, as found in an aircraft. Please note, that not every airline recognizes this seal as valid, therefore it is essential to refer to your airline’s regulations to confirm whether you can use your seat, even if the seat has the seal of approval.

General

Can I use this car seat on a flight?

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

Can I also use the infant car seat without the base?

Yes, your infant car seat can be installed in a car without using a base: In this instance, the car seat is installed using the vehicle belt. This is useful when travelling in a taxi or a second car. However, we recommend using the infant car seat in conjunction with the base, for better safety and stability. If installing the infant car seat on the front passenger seat, it is important to ensure that the front airbag has been deactivated.

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.

Where can I get replacement parts for my product?

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

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.

Can I wash the newborn inlay and car seat cover in the washing machine?

Yes, both are washable. We recommend using a delicate wash cycle and a maximum temperature of 30 degrees Celsius. Detailed instructions can be found in the User Guide.

Can I also use the infant car seat in a car without ISOFIX anchorage points?

When this infant car seat is used in conjunction with a base, it can only be installed either in i-Size approved vehicles or in vehicles with ISOFIX anchorage points. If you are installing the car seat with the vehicle’s 3-point belt, ISOFIX anchorage points are not required. Before purchasing the seat, please refer to the Car compatibility list on our website to see whether or not the car seat is compatible with your vehicle.

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 of the car seat 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.) Please note that a car seat should never be dismantled for cleaning. Please always refer to your car seat’s user manual when carrying out care and maintenance on your car seat. Generally the seat covers are machine washable at a maximum temperature of 30˚C on a delicate cycle. If you wash them at a higher temperature, the cover fabric might lose its color or shrink. Please wash the cover separately and never dry it by machine or in direct sunlight. (Warning: Only the cover of the car seat can be machine washed. The car seat itself is not machine washable.) Should you wish to clean a car seat more thoroughly than recommended above, you will have to have it cleaned professionally. Please ask the retailer who sold you the car seat to refer you to a professional service.

Installation and Securing your child

When I install the car seat using the vehicle belt, my baby’s head nods forward onto his/her chest even though the seat appears to be positioned horizontally. How can I prevent this?

If your child’s head is nodding forwards while sat in the infant car seat belted with the vehicle belt, this may indicate that the infant car seat is not positioned at a horizontal level, even though the symbol on the seat seems to indicate that it is. One reason for this is that many vehicle seats have a relatively steep incline, especially in smaller vehicles. Therefore, when installing the infant car seat it is best to use the level of the road as a guide to the correct level of the car seat, rather than the angle of the vehicle seat. If your baby’s head continues to nod forward even when the seat is aligned with the level of the road or you are using the base then it is possible that the baby is not wearing suitable clothing. Please refer to the question: What kind of clothing should my child wear when seated in the car seat.

Can I install a rear-facing seat on the front passenger seat?

Rear-facing car seats must only be installed on the passenger seat if the front airbag has been deactivated. Placing your child on a passenger seat with an activated airbag poses an enormous risk of injury, and we at CYBEX strictly advise against this. For other types of car seats check the user manuals of both your car seat and your vehicle to find out if you should deactivate the airbag. Statistics show that the safest place for a car seat is on the rear seat behind the front passenger seat. Side airbags do not put your child’s safety at risk. If you have no choice other than to use the front passenger seat, please ensure that the seat is pushed back as far as possible and that the airbag is deactivated.

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.

What should I bear in mind when installing the car seat in my vehicle?

Before purchasing the car seat it is important to check if it is approved to be used in your vehicle: • We advise going to www.cybex-online.com and checking the ‘More info’ section on the product page to find out whether the car seat is compatible with your vehicle • Compatibility can also be checked with typelist that can be found attached to your car seat (please do not use any part of this car seat on its own or in combination with boosters, backrests or headrests from other manufacturers or from different CYBEX product lines) • The car seat can be used only on vehicle seats which are equipped with an automatic 3-point vehicle belt. • For proper protection of your child, it is essential to use and install the car seat according to the instructions given in the User Guide. The User Guide can be found attached to the car seat, or it can be downloaded on www.cybex-online.com.

Can I install this infant car seat on the front passenger seat?

This infant car seat should only be installed on the passenger seat if the front airbag has been deactivated. Important: According to rules of the road such as the Highway Code in the UK, it is forbidden for your child to travel on a seat with an activated airbag. Placing your infant on a passenger seat with an activated airbag puts your child at risk of serious injury. If you have no choice other than to use the front passenger seat, please deactivate the airbag and ensure that the seat is pushed back as far as possible. As a rule we always recommend installing the car seat on the vehicle’s rear seat (if possible behind the passenger) as statistics show that this is the safest place in the car. In a head-on collision, a child will be protected by the larger crumple zone of the rear seat where front airbags do not put your child’s safety at risk.

Where should I install a car seat in my car?

The safest place for a car seat is in the rear seat behind the front passenger seat. It may be possible to install a CYBEX car seat on other seats in the vehicle. You can find this information in our vehicle Type List which is available either online or along with the product when it is purchased.

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

No. As you can only use this car seat rear-facing, it cannot be used on rear-facing vehicle benches. A rear-facing car seat on a rear-facing vehicle bench would be front-facing when installed.

Most commonly asked questions

How do I know when my child needs to change to the next car seat?

We generally advise against switching from an infant car seat (Gr. 0+, 0–13 kg, birth up to approx. 18 months) to the next seat prematurely. Even if your child’s feet protrude outside the infant car seat or your baby can already sit up, your child has not necessarily grown out of the seat. However, if your child's head is protruding above the top edge of the seat and he or she weighs over 13 kg, it is time to change the seat, as it no longer provides sufficient protection to the vulnerable neck and head area.

When should I remove the newborn inlay?

The inlay can be removed after approx. 3 months to provide more room for your growing baby. For more details on how to remove the newborn inlay, please refer to the User Guide.

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.

Are both side-impact protectors (L.S.P.s) needed?

The Linear Side-impact Protection (L.S.P.) reduces the forces of a side-impact collision and thus also the risk of injury. Generally, we advise parents to install or fold out the L.S.P. on both sides of the car seat. However, if there is insufficient space for the L.S.P. nearest the middle of the vehicle, it is not absolutely essential. For safety reasons, please ensure that the L.S.P. nearest the door is always installed or folded out.

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. • 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 manual or contact our Customer Service.

Usage

Can I leave my child in the infant car seat outside the car, for example at home?

CYBEX infant car seats have been engineered to offer the best possible protection for a baby during a car ride without affecting the child´s spine in a negative way. The Cloud Series also allow a lie-flat position outside the car. However, for safety reasons we do not recommend leaving the baby sat in the infant car seat for long periods of time, whether inside or outside the car.

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.

Do I need a newborn inlay for a car seat?

Yes, a newborn inlay is necessary to help very young and small babies lie in a safe and comfortable position in the car seat. These are specially designed to meet the anatomical requirements of newborn or very small babies. All CYBEX infant car seats include removable newborn inlays. Usually these can be removed when your child has reached a height of 61 cm, however always refer to the user guide provided with the product to ensure it is removed at the appropriate time.

When is a child too big for this infant car seat?

This infant car seat can be used from birth up until the child is approximately 18 months old (maximum body height 80 cm, maximum body weight 13 kg).
