How to "Jump start" a 2003 Cadillac DeVille;

1) Start with the ignition off, key out on the dead car.

2)Under the hood, on the passenger side, there is a red plastic cover with a + symbol on it. open this cover and attach the Positive (Red) cable to the copper bolt.

3) On the engine (passenger side engine top) there is a silver tab marked "NEG" attach the Negative (Black) cable here.

4)Attach the other end of the jumper cables to the other car (engine off).

5) Start the dead car and remove the cables from both cars, close the hood(s) and you are done!
