Hello! Erik from Sweden here again! Thanks for helping out! I'm once again wondering about my Avensis -07. When driving with the cruise control, and using it to accelerate, the car will keep accelerating even when I let go of the cruise controller at desired speed. It then accelerates another 3mph before it starts to decelerate to the wanted speed. It behaves like this uphill, downhill and flat. A mechanic said it is normal for a cruise control to behave like this, is that true?
