How to Jump Start a Cadillac VISTIQ

1. Check that the other vehicle has a 12-volt battery with a negative ground system, and park the vehicles close but not touching.
2. Set the parking brake on both vehicles and put them in P (Park), then turn both vehicles off and switch off or unplug accessories.
3. Open the liftgate, lift the load floor, and pull the covers to reach the positive terminal and negative grounding point.
4. Connect one end of the red positive (+) cable to the discharged battery positive (+) terminal, then the other end to the good battery positive (+) terminal.
5. Connect one end of the black negative (−) cable to the good battery negative (−) terminal.
6. Connect the other end of the negative (−) cable to the discharged battery negative (−) grounding point.
7. Start the vehicle with the good battery and let it run for a while, then try starting the vehicle with the dead battery.

• Inspect the jumper cables first; do not use cables with loose or missing insulation.
• Remove the cables by reversing Steps 11–14 exactly, then let the started vehicle idle for several minutes.
• If it will not start after a few tries, it probably needs service.
