Greetings Diego, the operation is simpler than it seems, in my isuzu trooper active first with a button the "automatic pilot", then there is a command like the light crossing and on this one a button which is set coast, summarizes, cancel, to put it to work you must first reach the speed that you want to "walk", once the desired speed is reached. You can rest your feet on the carpet, if you step on the brake, the system releases the pedal, which deactivates the automatic pilot, to resume again it is only enough to summarize it and it will accelerate until reaching the speed you set initially, if you want to cancel you give you cancel, and it is deactivated, another detail some systems do not activate at low speed, in my case I have to go to more than 40kph to activate the pilot. Do the test and tell us, luck.
