Checking Coolant Level and Adding Coolant
The coolant provides year-round protection from corrosion and freezing down to -31 °F (-35 °C) (-40 °F (-40 °C) in Nordic countries).

Regular checking of the coolant level is part of servicing. The coolant level only needs to be checked when a warning message appears on the multi-function display in the instrument panel.

  • Use only antifreeze authorized by Porsche.
  • Check the coolant level regularly.

Swallowing Engine Coolant
Coolant is hazardous to health. Coolant can be deadly to children or pets if consumed.

  • Keep coolant out of children's reach.
  • Also, keep coolant away from your pets. They can be attracted to it should there be a spill, or to used coolant left in an open container.

Hot Engine Coolant
The coolant becomes very hot when the engine is running and can burn you.

The coolant reservoir is pressurized. Careless opening of the coolant reservoir can lead to hot coolant suddenly spraying out.

  • Do not open the cap of the coolant reservoir when the engine is hot.
  • Only add coolant when the engine is cold and the vehicle is level.

Checking the coolant level when a warning message appears on the multi-function display in the instrument panel:

  • Remove cover.
  • Read off the engine coolant level.
    When the engine is cold and the vehicle is level, the coolant level must be between the markings A and B.
  • If the coolant level is below the MIN marking B, add coolant.
  1. Open cap on the reservoir carefully and allow any overpressure to escape.
    Then unscrew cap completely.
  2. Do not exceed the A marking.
    Only add a mixture of antifreeze and distilled water in equal parts.
    Antifreeze in coolant:
    50 % provides antifreeze protection down to -31 °F (-35 °C).
  3. Screw the cap on the reservoir closed until it locks securely.
  4. Have the cooling system checked at your authorized Porsche dealer.


If water is added without antifreeze in an emergency, the mixing ratio will have to be corrected.

A significant loss of coolant indicates a leak in the cooling system.

  • The cause must be eliminated without delay. Swallowing Engine Please see your authorized Porsche dealer.
