I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
Thank you for your attention to the rating requirement.


you have lost fluid for the system. you can add new chf 11s fluid in the reservoir that is marked with that on the star shaped cap, however, you will ultimately need to have the car raised on a hoist and the least source identified so that it can be repaired. typically this is not a repair that can be done at home.


Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
