from another Porsche forum
"Adaptive Cruise Control is deactivated automatically if the radar sensor is very dirty or is covered in ice or by an obstacle, in unfavourable weather conditions (heavy rain) or when driving through tunnels.

The message “ACC/PAS not available” appears on the multi-function display of the instrument panel. Always keep the radar sensor clean and free of ice and snow to ensure that it is fully functional.
"

"My similar problem to yours, namely the ACC/PAS Unavailable message illuminating appears to have been caused by a voltage drop on engine start when it was cranking at about 75rpm. This led to an inspection of the battery which appeared not to be holding charge (a loss of 25% over a 24 hour period). When the battery compartment was opened, it was full of water - 6 ltrs to be precise - which caused the battery terminals to corrode, as well as corrosion to the sub-woofer and several other electrical components. The leak was caused by the right rear sunroof drainage tube not being routed correctly to the external drain hole which caused water to ingress into the battery compartment. No-one can be sure but, given that nothing would have caused the pipe to be dislodged, it must have been like that since the day it was manufactured. I am very grateful to the senior technician at my OPC for his diligence - a couple of bottles of decent wine will be winging their way to him by way of thanks - he has prevented what appeared to be an innocuous problem from developing into something more serious."

Never seen the three letters GRA definitely defined, my guess is as the ACC uses Radar is something like General Radar Alert

I suspect either the sensors faulty or dirty or earth/battery charge issue with electrics which on all modern cars can give false alerts

Thank you pmg...I just rang the opc and told me exactly what you say..he did not know what the GRA stands for but advised to clean the Radar sensor .
Just cleaned the front radar sensor and lane assist sensors too ..will see what happens..nothing on dashboard so far!
I will check batteries heads if it appears again.

Thank you pmg..you are great.

GRA = geschwindigkeitsregelanlage, German for cruise control. Apparently!

I got the same warning this afternoon partway through a journey. My ACC fault is...I don't have Adaptive cruise! :P After a break the message was gone on restart.
