NOTE: NOTIFICATION
Cooling circuit not filled correctly

Risk of damage to vehicle components
→ After relieving the system pressure, do not start the engine or high-voltage system.

→ Fill and bleed the cooling system correctly before starting the engine or high-voltage system.

Information

The coolant filled in at the factory is intended to suffice for the entire service life. As long as the coolant is not contaminated by foreign bodies or other fluids it need not be changed.
Different coolant additives must not be mixed and doing so may damage the cooling system. Only use original Porsche coolant additives.
The coolant must be set to antifreeze protection of -37°C. This corresponds to a mixing ratio of 50: 50 (coolant additive: water). This mixing ratio provides optimum corrosion and antifreeze protection.
Coolant additives, coolants and cleaning agents must be disposed of according to the respective, applicable national laws.
Seals in the cooling system must be replaced by new ones following disassembly.
