How to Jump Start a Cadillac CTS-V

1. Park the vehicles close enough for the cables to reach, but make sure they do not touch each other.
2. Set the parking brake firmly on both vehicles, with an automatic in P (Park) or a manual in Neutral.
3. Turn off the ignition on both vehicles, unplug unneeded accessories, and turn off the radio and unneeded lamps.
4. Open both hoods and find the positive (+) and negative (−) terminals, or the remote ones, on each vehicle.
5. Connect the last end of the negative (−) cable at least 45 cm (18 in) from the dead battery, away from moving engine parts.
6. Use the remote negative (−) ground location on your vehicle for that last connection.
7. Start the vehicle with the good battery and let the engine run for a while.
8. Try to start the vehicle with the dead battery; if it will not start after a few tries, it probably needs service.

• Reverse the connection sequence exactly when removing the jumper cables.
• Connecting or removing the cables in the wrong order may cause electrical shorting and damage not covered by warranty.
• The pages shown do not include the early cable connection steps 5 to 8, so the full connection order is incomplete here.
