Mercedes-Benz S-CLASS SEDAN 2023 Child Restraint Systems for Transport User Manual
Suitable Child Restraint Systems for the Transport of Children
Information on the advantage of a rearward-facing child restraint system
Transport a baby in a suitable rearward-facing child restraint system only. It is also preferable to transport a small child in a suitable rearward-facing child restraint system. In this case, the child sits in the opposite direction to the direction of travel and faces backward.
Babies and small children have comparatively weak neck muscles in relation to the size and weight of their head. The risk of injury to the cervical spine during an accident can be reduced in a rearward-facing child restraint system.
Securing the child restraint system
Adjusting the seat correctly
When installing a child restraint system on the left or right rear seat, always observe the following:
- Make sure that the child’s feet do not touch the front seat. If necessary, move the front seat slightly forward. If the head restraint of the child restraint system cannot be fully extended when it is installed in the vehicle, this will result in restrictions on the maximum size setting for certain child restraint systems. Observe the child restraint system manufacturer’s installation instructions.
- Contact with the roof when the head restraints are fully extended and locked in place will not result in any restrictions on use. ® When installing an ISOFIX child restraint system, also observe the following:
- When using a rearward-facing child restraint system on a rear seat: adjust the front seat so that it does not touch the child restraint system.
- When using a forward-facing child restraint system with an integrated child seat belt: adjust the head restraint of the respective seat so that it does not push the child restraint system forward. If necessary, the respective head restraint can be removed. In addition, the backrest of the child restraint system must lie as flat as possible against the backrest of the vehicle seat. After the child restraint system has been removed, replace the vehicle head restraint immediately and adjust correctly.
- The child restraint system must not be put under strain between the roof and the seat cushion and/or be installed facing the wrong direction. Where possible, adjust the seat cushion inclination accordingly.
- Adjust the vehicle head restraints so that the child restraint system is not put under strain by the head restraint.
- When installing a belt-secured child restraint system, also observe the following:
- When using a rearward-facing child restraint system on a rear seat: adjust the front seat so that it does not touch the child restraint system.
- Also secure Top Tether if available (/ page 78)
- When using a forward-facing child restraint system with integrated child seat belt: adjust the head restraint of the respective seat so that it does not push the child restraint system forwards. If necessary, the respective head restraint can be removed. In addition, the backrest of the child restraint system must lie as flat as possible against the backrest of the vehicle seat. After the child restraint system has been removed, replace the vehicle head restraint immediately and adjust correctly.
- The backrest of the forward-facing child restraint system must, as far as possible, be resting on the seat backrest of the rear seat.
- The child restraint system must not be put under strain between the roof and the seat cushion and/or be installed facing the wrong direction.
- Where possible, adjust the seat cushion inclination accordingly.
- Adjust the vehicle head restraints so that the child restraint system is not put under strain by the head restraint.
- Make sure that the child’s feet do not touch the front seat. If necessary, move the front seat slightly forwards.
Depending on the vehicle equipment, always observe the following when installing a belt-secured child restraint system on the front passenger seat:
- Observe the notes on rearward-facing and forward facing child restraint systems on the front passenger seat (/ page 71).
- When using a forward-facing child restraint system integrated child seat belt: remove the head restraint from the respective seat, if possible. After the child restraint system has been removed, immediately replace the head restraint and adjust correctly.
- The backrest of the forward-facing child restraint system must, as far as possible, be resting on the seat backrest of the front passenger seat.
- The child restraint system must not be put under strain between the roof and the seat cushion and/or be installed facing the wrong direction.
- Adjust the vehicle head restraints so that the child restraint system is not put under strain by the head restraint.
- Never place objects (e.g. cushions) under or behind the child restraint system.
- Set the front passenger seat as far back as possible and move the seat into the highest possible position. Always make sure that the shoulder belt strap is correctly routed from the seat belt outlet of the vehicle to the shoulder belt guide on the child restraint system. The shoulder belt strap must be routed for-wards from the seat belt outlet and, where possible, downwards to the child restraint system.
- Fully retract the seat cushion length adjustment.
- Adjust the seat cushion inclination so that the front edge of the seat cushion is in the highest position and the rear edge of the seat cushion is in the lowest position.
- Set the seat backrest to the most vertical position possible.
Activating or deactivating the special seat belt retractor of the seat belt
WARNING
Risk of injury or death if a seat belt is unfastened while the vehicle is in motion If the seat belt is released while the vehicle is in motion, the special seat belt retractor is deactivated and the child restraint system is no longer correctly secured. The seat belt is drawn in slightly by the inertia reel and cannot be immediately closed again.

- Activate the special seat belt retractor again and correctly secure the child restraint system.
- When enabled, the special seat belt retractor ensures that the seat belts of the front passenger seat and rear seats do not slacken once the child restraint system is secured.
The seat belts on the following seats are equipped with a special seat belt retractor:
- Front passenger seat
- Rear seats
- Installing a child restraint system

- If the child is secured in a LATCH-type (ISOFIX) child restraint system with an integrated seat belt, the total mass of the child and child restraint system must not exceed 73 l b (33 kg). Always comply with the information about the mass of the child:
- in the manufacturer’s installation and operating instructions for the child restraint system used
- on a label on the child restraint system, if present Regularly checks that the permissible gross mass of the child and child restraint system is still complied with. When installing a child restraint system, observe the following:
- Always observe the correct use of the seats and consider their suitability for attaching a child restraint system.
ISOFIX mounting brackets
Before every journey, make sure that the ISOFIX child restraint system is engaged correctly in both mounting brackets in the vehicle.
NOTE

- Never adjust the seat after the child restraint system has been installed.
If the child restraint system is equipped with a Top Tether belt:
The risk of injury may be reduced by Top Tether. The Top Tether belt enables an additional connection between the child restraint system attached with LATCH-type (ISOFIX) (left and right rear seats) or the seat belt (all rear seats) and the vehicle.
- Canada: Only the two outer Top Tether ancho rages are available.
- If necessary, slide head restraint 1 upwards (/ page 127).
