Electronic Brake Force Distribution (EBD): Automatically varies the amount of force being applied to the road wheels. Typically, the front end of a motor vehicle carries the most weight so braking force needs to be adjusted and distributed taking into account varying load conditions, decelerating and cornering to help avoid the vehicle skidding out of control. It works in conjunction with ABS.
Older vehicles have a pre-set manual proportioning valve to help control front-to-rear brake pressure.
Electronic Stability Programme (ESP, VSA, VDC, ESC, DSC): Detects loss of steering control such as over-steer or under-steer. Automatically applies individual braking to each road wheel to help bring the vehicle back under control. Some systems also reduce engine power and assist with the correct steering direction.
Supplemental Restraint System (SRS): Used in partnership with seatbelts. When the SRS system detects occupant safety is at risk during a collision, sensors deploy multiple airbags automatically to help protect occupants from frontal, pelvic, side and head impact injury.
Automatic Emergency Locking Retractors (AELR): Fitted to rear seatbelts. When fully extended and released slowly they ratchet back into position and lock to secure child safety seats. Many owners are unaware of this feature.
Active Cruise Control (ACC): Maintains a set speed like a conventional cruise control system with the added benefit of being able keep a pre-determined distance from the vehicle in the same lane ahead.
When sensors detect the vehicle is approaching another ahead, the system automatically eases off the throttle or applies the brakes to maintain a constant and safe gap. This distance can be pre-set and adjusted.
High Intensity Discharge Headlights (HID): Produce light by way of an electric arc between electrodes housed within a tube. The tube contains a gas which facilitates the arcs initial strike.
HID lights are brighter, more energy-efficient and last longer than conventional incandescent lights. Allow drivers to detect road hazards at greater distances so are therefore deemed to improve driver safety.
