How do you change the battery on a 2003 Cadillac CTS?

Answer 1

Make sure the keys are out of the ignition first. Then check to see if your vehicle has any braces holding it in place. Once you've taken any braces off, disconnect the ground wire(black), it useally takes a 1/2 inch wrench. Then take your hot wire off(red). These are all the workings of a person being self sufficient. Good luck.

Answer 2

First off, the battery is located under the rear seat, gab the front lip of the seat and pull up. There is no latch to release just pull upward. From there on is just a side terminal battery, 8mm wrench for the side terminals and a 13mm for the hold down bolt. There will be a vent tube connected to either side of the battery just pull them off. The battery will need tipped in various ways in order to get it out from under the from of the seat support. From there just reverse the steps and you are all set.
