The central locking system locks and unlocks the doors as well as the luggage and engine compartments. When the doors are locked, inside release knobs are all lowered. If airbags inflate in an accident, all doors are automatically unlocked. Additional safety settings offer extra convenience: automatic locking of the luggage compartment or safety central locking. All doors and the luggage compartment are then locked automatically when the car is driven at a speed of 6 mph or faster. The luggage compartment locks when the speed is greater than 3 mph, and the safety central locking only initially allows only the driver’s door to be opened. A second opening movement opens the remaining doors as well as the tailgate.
