Edema is the medical term for swelling. Body parts swell from injury or inflammation. It can affect a small area or the entire body. Medications, infections, pregnancy, and many other medical problems can cause edema. Edema happens when your small blood vessels become leaky and release fluid into nearby tissues.
Audi's adaptive cruise control is available on most models as part of the Advanced Technology Package or Driver Assistance Package. BMW's adaptive cruise control is available on most models as part of the ACC Stop & Go + Active Driving Assistant addition to the Driver Assistance Plus package.
How does adaptive cruise control work? Adaptive cruise control uses a small radar (or laser) unit under the front grill or bumper that measures the distance to the vehicle in front of you. Many automakers will actually use two radarsâone for close range and a second for vehicles that are further out.
