The suspension is programmed to do a number of things automatically. The vehicle has two different ride heights. The first is the parked height. This is the the height the car rests to when parked. To account for the weight of passengers and luggage, the car has a predetermined height that it will raise to when making height corrections. When you get in and drive the car, it raises 20mm above where it was sitting when parked. If you accelerate to 105km/hr (~63mph), the vehicle drops 20mm for a more stable high speed profile. As soon as your speed decreases to ~45mph, the vehicle raises 20mm. When you park the car and shut the last door, it drops 20mm down to parked height.
