When new, the power folding top hydraulic fluid is golden clear. As the system is cycled, it picks up the carbon black from the numerous
O-ring seals used in the system. The carbon black acts like a dye and causes the fluid to darken considerably and take on a black appearance.
This is a normal occurrence and no repair attempts should be performed, as replacement fluid will also darken.
