WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2019 Porsche 911, 2018 Porsche 911, 2017 Porsche 911, 2016 Porsche 911, and 2015 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

Information

When filling the hydraulic system, proceed with utmost care to ensure that dirt does not get into the system.
Before unscrewing the screw plug, place a cloth underneath the hydraulic unit to catch emerging hydraulic oil.
The hydraulic convertible top uses a closed hydraulic system. In general, the hydraulic system will need to be filled only if the hydraulic circuit was opened (after parts replacement). Only Original Porsche hydraulic oil → OIL must be used when changing or topping up the hydraulic oil.

Information

When screwing in the screw plug, check that the seal is touching the screw head.
