For the auto hold,stop at lights etc,green light on dash lights up,take your foot off the brake,when ok to go just accelerate away.
I normally leave leave auto hold turned off,if I approach lights and looking like a delay,I then turn auto hold on,take foot off brake and start off with accelerator and drive off.
You are able to monitor traffic lights and gently press accelerator just before lights change and accelerate off without any delay.
With auto hold on,if you brake gently on approach to eg.stop sign,auto hold will not engage and you are able to proceed when safe.
Hope this helps Beachie1
