Installation with base: Pay attention to the i-size logo. If a vehicle seat is marked with this logo, it is suitable for use with all i-size child seats and therefore will not appear in our list of compatible vehicles. If your vehicle does not have an i-Size seat, please check the compatibility of your vehicle. If your vehicle is not displayed, please contact our customer service team.
Easy Boarding Position
The 360° rotation mechanism eases the child’s entry and exit, relieving strain on parent’s backs. The seat can be rotated using only one hand even when in a reclined position, allowing even the youngest passenger to be boarded ergonomically. The rotation mechanism makes switching between rear and forward-facing positions easy.
Safe Travels up to 4 Years
In its rear-facing position Sirona Z2 i-Size reduces the risk of injury in a head-on collision. Tests show that the force of impact from a frontal crash is distributed more evenly over a large area of the car seat shell. Rear-facing travel is mandatory until the child is over 15 months old (76 cm), and we recommend that the child stay rear-facing until they are at least four years old.
Maximum Comfort in the Car
The one-hand recline function makes it easy for parents to adjust the seat while keeping their other hand free. The Sirona Z2 i-Size car seat has 5 recline positions in both rear and forward-facing modes, increasing comfort for sleeping and travelling.

Check your Car Compatibility
To confirm whether this car seat is suitable for installation in your vehicle, please use our Car Compatibility Checker.
Base Z2
The Sirona Z2 i-Size clicks on and off the Base Z2. This is installed using a load leg and ISOFIX. The Base Z2 ensures safety and stability, and it can also be used with the Cloud Z2 i-Size baby car seat. Look for the i-Size logo in your vehicle to check compatibility. If there is no i-Size logo but your car has ISOFIX, please check our Car Compatibility tool.
Will the 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 car seat is approved for use in i-Size compatible vehicle seating positions as indicated by vehicle manufacturers in their vehicle User Guides. If your vehicle does not have an i-Size seating position, please check the Car Compatibility Checker on the CYBEX Website.
Can I use this car seat on a flight?
No, this car seat is not approved for use on an airplane.
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.
When should I remove the newborn inlay?
The newborn inlay has to be removed when your infant reaches a height of 61 cm (corresponding to approximately 3 months). This ensures that your growing baby has enough space in the car seat.
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.
When I remove the base from the vehicle it emits a warning signal. How can I stop this noise?
When the load leg is adjusted the base will emit a warning signal indicating that it is not correctly installed. If you want to remove the base from the vehicle, first push the load leg upwards to its uppermost position by pushing the adjustment button. Then fold the load leg back for storage within the base. The warning signal will stop when the load leg is fully folded back and in the designated area. If the base is not to be used for a long period of time the battery should be removed to avoid potential damage caused by leaking fluids.
My child keeps trying to wriggle out of the harness system. What can I do about this?
As a general rule, you can secure your child in the safest possible way if you follow these instructions: The impact shield should be positioned so it fits snug against the body without causing discomfort. The impact shield can also be adjusted in depth for a comfortable fit on the majority of models. You can tell that the impact shield is in the correct position if it is fully aligned with your child's body. Thick clothing prevents the harness/vehicle belt or impact shield from fitting tight to the body. Only a correctly adjusted restraint system can offer maximum protection. For this reason, your child should wear thin, close-fitting clothing. Thick clothing such as winter jackets and clothing with hoods (hoodies, teddy suits, etc.) as well as hats should be avoided. Once your child has been positioned in the seat, he or she can be covered with a blanket for warmth.
When am I allowed to use the Sirona's forward-facing position?
Once the child exceeds 15 months of age and has reached a minimum size of 76 cm you are allowed to use the forward-facing position of your Sirona car seat. This is not a must. We rather recommend transporting children in the Sirona's rear-facing position for as long as possible. The car seat allows rear-facing travel up to a height of 105 cm (approx. 4 years).
Can I wash the newborn inlay and cover of the car seat in the washing machine?
Yes, both are washable. Note however, that the foam in the newborn inlay needs to be removed before washing. It can be pulled out via slots in the fabric. You can put the foam back through the slots after the newborn inlay is washed and dried. We recommend using a delicate wash cycle and a maximum temperature of 30 degrees Celsius. Detailed instructions can be also found in the User Guide.
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 Guide 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.
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.
Can I use the car seat on rear-facing vehicle benches (e.g. in vans or minibuses)?
No. This car seat cannot be used on rear-facing vehicle benches.
What do I have to bear in mind when installing the Sirona in my vehicle?
First, select an appropriate vehicle seat. Unfold the load leg until it locks with an audible CLICK. Release the buttons of the ISOFIX locking arms and push them out of the base to their furthest extent. Insert the arms into the ISOFIX anchorage points (make sure they lock with an audible CLICK and that the safety indicators show green). Push the base towards the backrest of the vehicle seat until it is fully aligned with the backrest. Moving the whole car seat back and forth, and from side to side will further brace it against the backrest. Always make sure that the load leg is extended completely (pull out the load leg by pushing the adjustment button until it touches the vehicle floor). Pull the leg out and into the next locking position (make sure the load leg indicator on the base shows green).
Can I also use this seat in a car without ISOFIX anchorage points?
No, this seat can only be installed in vehicles with ISOFIX anchorage points, due to the fact that it must be installed with ISOFIX in every position.
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. If your vehicle has an i-Size seating position compatibility is given. If you have no i-Size seating position, please 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 of your product. 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. It can be downloaded via the CYBEX Website.
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.
Can I use the Sirona Z2 i-Size with a Base Z?
Yes, the Sirona Z2 i-Size can be used in combination with a Base Z. Please note that the functionality of the car seat depends on the base. The reclining position of the Sirona Z2 i-Size may be restricted with a Base Z compared to a Base Z2. Accordingly, we recommend the use of the Base Z2.
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.
Is my child allowed to rest his/her legs on the rebound bar?
Relatively tall infants may rest their legs on the rebound bar. Bending the legs at the knee does not affect safety in any way. As long as the child has sufficient legroom you can use the seat in a rear-facing position.
The car seat is approved in compliance with the i-Size standard (UN R129). What does this mean?
i-Size is a European standard for car seats. Among other regulations i-Size states that infants must travel in a rear-facing position before the child's age exceeds 15 months and that, for the first time, side-impact protection is tested. To find out more about i-Size, check our Safety page on the CYBEX Website.
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.
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.
How do I know when my child needs to change to the next car seat?
We generally advise against switching to the next car seat prematurely. Even if your child’s feet protrude outside the car seat, your child has not necessarily grown out of the seat. However, if your child's head is protruding above the top edge of the highest headrest position, is taller than 105 cm, or weighs over 18 kg, it is time to change the car seat as it no longer affords sufficient protection to the vulnerable neck and head area. After changing the car seat, your child’s head should be positioned within the protective area of the height-adjustable headrest. If the new car seat has an impact shield, your child should be able to comfortably see over it. If your child disappears behind the impact shield, then he/she is definitely too small for the seat.
When is a child too big for the Sirona?
The Sirona can be used by infants between 45 cm and 105 cm in height or up to a maximum bodyweight of 18 kg (approx. 4 years).
How do I install the cup holder?
On either side of the car seat there are little openings in the fabric of the seat cover indicated by stitching. If you look inside either of these openings you will see a grooved area in the car seat shell which the cup holder can be slotted into.
When can I turn a car seat forward-facing?
UN Norm R129 states that children must travel in a rear-facing position up until they exceed the age of 15 months and a height of 76 cm. However, given the current state of child restraint technology we recommend placing a car seat in the rear-facing position until the child is 4 years old, or as long as this is possible. At the beginning of their lives children generally have relatively weak neck muscles and large heads in relation to the rest of their bodies. The older they get, the stronger their neck muscles get, and the difference in size between the head and the body evens out. However, in the event of a collision in the early years of development these two factors create a large amount of strain on their necks, making car crashes statistically more dangerous for this age group. Physicians, accident researchers and consumer and health organizations recommend transporting babies and toddlers in rear-facing child seats for as long as possible, but at least until they are 4 years old. If the child is travelling in a rear-facing position, the forces of an impact are distributed evenly over the large area of the car seat shell. The strain on the neck, head, and chest is significantly reduced, reducing the risk of injury when compared to a forward-facing car seat.
