Volvo recommends that children travel in rear-facing child seats until as late an age as possible, at least until 3-4 years of age, and then front-facing booster cushions/child seats until up to 10 years of age.
The position of a child in the car and the choice of equipment are dictated by the child's weight and size; see Child seats.
Note
Volvo has child safety equipment (child seats, booster cushions & attachment devices) which is designed for your particular car. Using Volvo's child safety equipment provides you with optimum conditions for your child to travel safely in the car. Furthermore, the child safety equipment fits and is easy to use.
Note
Child safety locks
The rear doors and the windows in the rear doors* can be locked manually or electronically* to prevent them being opened from inside.
