Groupe PSA had anticipated changes in regulations by equipping its vehicles with driving assistance technologies aimed at helping the driver: pp the ABS, or Anti Blocking System, which stops the brakes from blocking when performing an emergency stop; pp the EBA, or Emergency Brake Assist, which increases braking power when performing an emergency stop; pp ESC, or Electronic Stability Control, which helps drivers maintain control even in a skid; pp TPMS, or Tyre Pressure Monitoring System, which alerts the driver to potential loss of air pressure that can destabilise the vehicle.
