Short answer: sometimes, but not indefinitely. Given this indicator's moderate priority, respect the warning colour and the car's behaviour. When in doubt with your Mercedes-Benz AMG GT, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Service Vehicle Soon Light on a Mercedes-Benz AMG GT?
