Hi, I have a new ix20 and the salesman described it as Intelligent Stop and Go. He described it would operate when the car was stopped and out of gear provided that the battery was fully charged and there was not a lot of drain on it (heater etc) and the temperature outside was above 4C. I just expected to switch it off and forget about it. However, every time the ignition is switched off and then on again it resets. Now I just leave it on and it has worked well. The only time I switch it off is if I am in a lot of crawling traffic and it is better switched off I feel.
