Travelling with a child starts with matching the child restraint to the child and the exact vehicle—not with assuming that a seat offered by a rental company will fit. The Spanish traffic authority (DGT) says that in Spain children up to 135 cm must use a restraint suited to their height and weight; its general rule is rear-seat placement, with exceptions described on the official page. DGT also describes an exception for children under 12 who are at least 135 cm tall: they may use the vehicle’s own belt directly. Within that exception, DGT recommends continuing with an approved restraint matched to height and weight until 150 cm. The recommendation up to 150 cm is not the same legal requirement as the rule for children up to 135 cm. Check the DGT page for the conditions and exceptions that apply to your case. [S1]

Before you contact the operator

Record your child’s current height and weight, and age as a useful secondary detail. Read the label and manufacturer instructions for the restraint you plan to use: note its approved height range and the required installation method. DGT advises following the specific instructions and checking that the restraint is properly secured. A restraint that fits one car is not automatically suitable for another. [S1]

Questions to ask before booking

  • Which exact vehicle is offered for our dates, and which seating position can be used for the child?
  • If you supply a child restraint, what exact model is it, what height range and approval are shown on its label, and can you confirm it is suitable for the child’s measurements?
  • How is that restraint installed in the exact vehicle and position? Please confirm against both the restraint instructions and vehicle manual.
  • If we bring our own restraint, can you confirm the exact model and installation method work with the offered vehicle?
  • Are there any position-specific instructions, including for airbags or anchoring points, that we must follow?

Do not rely on a review, a generic “child seat available” message or a vehicle feature list as proof of fit. If the operator cannot confirm the restraint and installation for the exact car, pause the booking and ask for a suitable alternative. You can also review the minivan category and specific listings such as the Audi Q7 or Chrysler Pacifica; those links do not guarantee availability or child-seat fit.
