The instant the engine starts reverse the procedure to disconnect the jumper cables.
When jumping a car why do you have to put the negative cable on ground?
You connect the negative cable last and connect it to ground rather than to the negative post of the battery because there may be a small spark when you make the connection. Batteries can emit a slight amount of highly explosive hydrogen gas. That spark on the negative post can cause these fumes to ignite and explode. That is why you always connect the negative cable last and always connect it to ground and not to the battery itself as a safety measure.
