Checking the fluid level:

The low convertible top fluid level can cause many problems, like the slow and blocked movement of the top. Hence, checking is very important. For that, firstly locate it, which will be behind the trunk lining. Look for the range of Min or Max on it; check if it is too full or low. Moreover, it should be slightly above the medium or as described in the manual. Otherwise, the air will go in it and can cause more problems.

Checking the Pump:

The pump is linked with the fluid level, and if the liquid level is below the Min, the air will pass into the hydraulic system, including the pump, and block it. Consequently, if you maintain the fluid level, there will be no problem with the hydraulic pump.
