How to Jump Start a Volvo XC70

1. Switch off the ignition by setting it to mode 0.
2. Connect the red jumper cable to the positive (+) terminal of the auxiliary battery.
3. Fold back the cover over the positive (+) terminal on your vehicle's battery and connect the other end of the red cable there.
4. Connect the black cable to the negative (–) terminal of the auxiliary battery.
5. Connect the other end of the black cable to the ground point on the right engine mount, at the top, on the outer screw.
6. Start the engine in the assisting vehicle, then start the engine in the vehicle with the dead battery.
7. Once the engine runs, remove the black negative (–) cable first, then the red positive (+) cable.

• If the auxiliary battery is in another vehicle, make sure the vehicles are not touching.
• Never use the battery's negative terminal on your vehicle; only the chassis ground point may be used.
• Do not connect a jumper cable to the fuel system or moving parts.
