Isofix is the result of the efforts of well-known car makers to create a uniform and optimal standard for anchoring child seats. Isofix is not an official DIN standard.

Isofix child seats are equipped with a simplified fastening device. They can be used in all cars which are already factory-equipped with standardised snap couplings.

The child seat preinstallation has two bars which are firmly attached to the car body. Isofix-type child seats are firmly attached by two connectors.

Isofix child seats can be fitted easily and offer the highest degree of safety due to being robustly attached to the car body.

All cars of the SEAT model range feature the Isofix system at the rear.

Under emergency braking conditions or slippery road surfaces, the anti-lock brake system (ABS) prevents the wheels from locking and maintains the car's steerability. Locked wheels can no longer transmit cornering forces, the car does not respond to steering commands. To prevent this from happening, the ABS control unit monitors the rotational speed of all wheels of the car by means of wheel speed sensors. If one of them threatens to lock, a solenoid valve in the control unit of the ABS reduces brake pressure for the respective wheel until it runs freely again, then the pressure is again increased up to the locking limit. The car remains stable and steerability is maintained. In modern ABS systems such as those employed in all SEAT models, this process takes place several times a second. The driver perceives the action of the ABS as a slight vibration of the brake pedal. In the ABS control range, despite maximum deceleration, the car can be steered easily to avoid obstacles and prevent a collision.
