Can I keep driving with the Cruise Control Light on?
For a Mercedes-Benz GLA, a steady amber Cruise Control Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Cruise Control Light on a Mercedes-Benz GLA?

Will the Cruise Control Light reset itself on a Mercedes-Benz GLA?
