Generally, a child under 10 travels in the rear using an approved restraint suited to their build. Exceptions exist, including certain rear-facing restraints in front with the airbag disabled.
Choose using the instructions
Check the seat’s range of use and compatibility with the car. Height, weight and build guide selection according to the device; age alone does not set the harness. A second-hand seat needs a verifiable history and components. Do not use it with a missing part or uncertain condition after an impact.
Install without improvising
Read both the seat and vehicle manuals. Follow the required belt path or anchors and inspect locking indicators where fitted. A support leg or top tether must not be removed to save space. If front installation of a rear-facing seat is legally permitted, the frontal airbag must be disabled according to instructions.
Check at every departure
Secure the child, check strap position and avoid thick clothing that interferes with tightening. Secure heavy objects and restrain other passengers. Stop to attend to a child; do not turn around while driving. If installation is unclear, ask the seller or a competent professional for a demonstration.
Approval and compatibility
Read the approval label and the seat’s height or weight limits. Check compatibility with the seating position and vehicle: ISOFIX attachments do not authorise every combination. Use the top tether or support leg where specified. Read the seat and car instructions together.
Repeat checks when changing cars
A seat moved into a rental car or relative’s car needs checking again. Inspect belt routing, tightness, support and harness position. Avoid buying a second-hand seat without its history or parts. Ask for a demonstration if an indicator or attachment is not understood.
You transfer a child seat into a rental car.
Check the seating position, anchors, indicators and both manuals. Install the seat again and adjust the harness with the child before driving.
What to avoid. Correct installation in one car does not automatically mean correct installation in another.
Practical checks
- Choose a suitable, compatible restraint
- Follow both installation manuals
- Check anchors and harness
- Secure luggage and restrain all passengers
