When driving my ICE people carrier I tend to put the car into N or P at traffic lights especially if I know I will be stationary for 30 seconds or more, a situation that is very typical in HK. When driving my MS I find putting the car into P a tad strange because the door handles would protract and the interior lights come on. Now, my question is, is it okay to leave the car in D and activate the Hill Hold function while the road is flat and doing it so frequently? Would I be putting stress on the brakes whilst the car tries to creep forward? I guess the other way of asking the question is, in what situation is the Hill Hold function designed for?
