Good Day Everyone
I’m a new driver and it’s my first time to drive a brand new car (automatic) … with lack of guidance and knowledge on the gear I had used + or - or 1 and 2 mode, I hit as much as 80kph on a highway on my first day… as to what I had observed: I can hear some noise on the engine once I step up the acceleration… and then on the 2nd day, a friend of mine told me that I should be on D ( driving mode ). After I tried that, the engine runs smoothly with no noise…my concern now is does this affect much on the engine or have any bad effect after what I have done running at 80kph at 1 and 2 mode? Your comment will help me a lot on this issue .
thank you very much
