If the car is equipped with a front passenger airbag, this is indicated by a special label, the location of which is shown in the figure.
Label warns that a child safety seat must not be placed in the front seat with the back of the seat facing toward the front passenger airbag module to prevent injury from possible airbag deployment.
Always follow the manufacturer's installation and operating instructions before installing the child seat.
