help with my volkswagen beetle.?

Can't you people get access to your manuals at least online? The fluid levels are clearly marked and color coded wit their dipsticks. Now when you've found the dipstick make sure it is the normal fluid color and level of fill. If the fluid is low go to an auto parts store and get the type for your car. If the fluid is brown or not in it's fresh state have it flushed and new filters and fluid.
