How to Jump Start a Ford Crown Victoria

1. Turn the heater fan on in both vehicles and switch all other accessories off.
2. Connect the positive (+) jumper cable to the positive (+) terminal of the discharged battery.
3. Connect the other end of the positive (+) cable to the positive (+) terminal of the assisting battery.
4. Connect the negative (-) cable to the negative (-) terminal of the assisting battery.
5. Make the final negative (-) connection to an exposed metal part of the stalled engine, away from the battery and fuel injection system.
6. Start the booster vehicle and run it at moderately increased speed, then start the disabled vehicle.
7. Run both engines for an additional three minutes, then remove the cables in reverse order of connection.

• Do not connect the second cable to the negative (-) terminal of the battery being jumped; a spark may ignite battery gases.
• Do not use fuel lines, engine rocker covers, the intake manifold or electrical components as ground points.
• After starting, let the engine idle several minutes so the engine computer can relearn its idle conditions.
