When the Stop/Start in a 500 is working properly, can you choose whether to stop the engine by pressing lightly or firmly on the brake pedal?
This would be useful when you stop and you know it will be for two seconds (light press; engine stays running), or two minutes (heavy press; engine stops).
I learned this is the case with Mazda's iStop system (so well-known now, everyone here calls the S/S system "iStop" in any car; I guess names beginning with "i" will always catch on, and Mazda 3/6 are top-selling cars here).
I suspect the only reason to turn S/S off is the prospect of unwanted one-second engine stops when driving in town; which the brake pressure technique avoids.
Some S/S systems try to explain what's happening. In my Golf 7, there's a green warning light (the same one that glows red for the handbrake being on). When the green light comes on after stopping, releasing the brake pedal will hold the brakes on and keep the engine running (Auto Hold must also be on). Pressing more firmly on the brake pedal after the light comes on will stop the engine, as long as the steering angle is less than a certain amount and the temperature inside the car is close to the chosen temperature. The engine will restart when the temperature differential becomes too great. If you navigate through a few menus and buttons, the 'stereo' touchscreen will even display the excuse for restarting or not stopping!
I've never seen a S/S-equipped 500 so I wondered whether there is some graphic on the LCD that shows, like the green light in my Golf, whether the engine is about to stop if the brake pedal is pressed harder.
