HOW TO USE
• This product is suitable for children between 100 and 150cm in height.
- Forward-facing installation for children between 100 to 150 cm in height made possible thanks to the Isofi x connectors. The child is strapped in with the car's 3-point seat belt. Alternatively, the child car seat in the 100–150 cm size class can also be fitted using the 3-point seat belt only. Connection with the Isofi x connectors is not mandatory, but it is recommended.
NOTE
This is an optimised i-Size children's booster seat. It is approved under Regulation No. 129 for use primarily on "i-Size vehicle seats" as specified by vehicle manufacturers in the vehicle manual.
If in doubt, the manufacturer of the enhanced child restraint system or the retailer should be consulted.
IMPORTANT - DO NOT USE THE CHILD CAR SEAT IN THE DIRECTION OF TRAVEL UNTIL THE CHILD HAS REACHED THE AGE OF 3.

WARNING
- Please read through these instructions carefully before use in order to guarantee the safety of your child. Retain the instructions. Non-compliance with the instructions in this manual may result in serious injuries to your child.
- For Isofi x installation: Be sure to read the car manufacturer's manual.
- Do not use load-bearing contact points other than those described in the instructions and indicated on the child restraint system.
- Do not use this child car seat at home. It has been designed exclusively for use in a car.
- Do not leave your child unsupervised in the seat at any time.
- The child seat must be replaced if it has been subject to severe mechanical stress in an accident.
- For safety reasons, the child car seat must be secured in the vehicle even when there is no child sitting in the child car seat.
- Always make sure that all straps that attach the child car seat to the vehicle are secure and that all belts that restrain the child are adjusted to fit the child's body. Ensure that the belts are not twisted.
- Items of luggage and other objects that could cause injury in the event of a collision must be properly secured.
- The rigid elements and plastic parts of a child restraint system must be positioned and installed so that they cannot become jammed by a movable seat or a vehicle door.
- It is important that belts that sit low hold the child's pelvis firmly in place. Your child should always be fastened in to stop them falling out.
- It is dangerous to make changes or additions to the product without approval from the responsible authority. Non-compliance with the installation instructions provided by the manufacturer of the child restraint system may also present risks to the safety of your child.
- This child seat is designed for children with a maximum height of 150 cm. Never overload the child seat by transporting more than one child or additional loads in it.
- The child restraint system must not be used without the seat cover.
- The seat cover must not be replaced by a cover other than that recommended by the manufacturer, as this seat cover is an important component of the restraint system.
