Park Both Cars: Ensure that both the dead car and the car providing power are parked and that the parking brakes are engaged.
Open the Hoods: Open both the hood of the dead car and the jumper cables.
Locate the Terminals: In the Volvo XC70, the positive (+) and negative (-) battery terminals are located in the engine compartment. Usually, they are marked with red (+) and black (-) symbols.
Connect the Positive Cables: Connect one end of the red (positive) jumper cable to the positive (+) terminal of the dead car. Connect the other end of the positive jumper cable to the positive (+) terminal of the working battery.
Connect the Negative Cables: Connect one end of the black (negative) jumper cable to the negative (-) terminal of the working battery. Then, connect the other end of the negative jumper cable to an unpainted metal surface in the engine compartment of the dead car (but not directly to the negative battery terminal). This grounding point should be away from fuel lines, battery, or moving parts.
Start the Working Car: Start the car with the working battery. Let it run for a few minutes to charge the dead battery.
Try to Start the Dead Car: Return to the dead car and attempt to start it. Turn the ignition and hold it for about 5-10 seconds. If the engine doesn't start, turn the ignition off, wait a minute, and try again.
Leave Working Car Running: If the dead car starts successfully, keep it running and let the working car remain connected for a few more minutes to recharge the dead battery further.
Disconnect Cables in Reverse Order: Disconnect the jumper cables in the reverse order you connected them:
Test Drive and Charge: Let the jumped car run for at least 30 minutes to recharge the battery further. Then, take it for a short drive to help charge it even more. Avoid using power-hungry electrical accessories during this time to maximize charging.
Note: When connecting and disconnecting the jumper cables, ensure you touch only the insulated parts to prevent accidental electrical shocks.
