How to Jump Start a Volvo V70

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 on your battery's positive (+) terminal and connect the other end of the red cable there.
4. Connect the black cable to the auxiliary battery's negative (–) terminal, then to the ground point on the right engine mount's outer screw.
5. Start the engine in the assisting vehicle, then start the engine of the vehicle with the dead battery.
6. Once running, 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.
• Do not connect a cable to the fuel system or moving parts, and keep flames and sparks away from the battery.
