Convertible top malfunction light on

[porscheguy]

The convertible top light has turned on ,on my 99 boxster. What does this mean??It goes down and closes still.Could it be the convertible top motor is low on oil or going bad???Also my temperature guage has been reading at the line after the 180 line, what could be causing this??? The temperature goes up quicker when the a/c is on . The coolant resivor is full.Where/ how do I see the motor/ radiator.(how do i get to the motor? /The top is also in the way). thanks
