WARNING: When starting the engine with a booster battery, carefully follow the operating sequence described in this subsection. Otherwise, a fire or explosion may occur, resulting in damage to both vehicles.
WARNING: Before connecting the external battery, make sure the ignition is off. Also turn off all electrical consumers (headlights, car radio, windshield wipers, etc.).
WARNING: When connecting or disconnecting wires, do not allow wires to touch each other or allow wires to come into contact with fans, drive belts, or other rotating parts.
WARNING: Do not disconnect the booster battery cables until the engine is running at normal idle speed.
WARNING: If you leave the audio system on while jump starting the engine, serious damage to the audio system may occur. Always turn off the audio system before jumping the engine with another vehicle's battery.
1. Place the vehicle with the discharged battery next to the donor vehicle within reach of the jumper cables.
WARNING: The vehicles must not touch each other under any circumstances. Otherwise, an unwanted short circuit to ground may occur, which will prevent you from starting the engine of the vehicle with a dead battery and may damage the electrical systems of both vehicles.
2. Apply the parking brake on both vehicles.
3. Check the electrolyte level in the discharged battery (see "Battery Maintenance").
WARNING: If the electrolyte level is very low or the electrolyte appears frozen, do not attempt to jump start the engine using a booster battery. This could cause the discharged battery to explode!
4. Connect the jumper cable clamp with red handles to the positive terminal of the discharged battery.
5. Connect the second cable clamp with red handles to the positive terminal of the donor battery.
NOTE: For clarity, the operation is shown with the battery removed.
6. Connect the clamp of the second cable (with black handles) to the negative terminal of the donor battery…
7. …and the second clamp of the cable with black handles — to the "ground" of the car with a discharged battery in a place located at the maximum possible distance from the battery. It is most convenient to attach the clamp to the bolt of fastening to the body of the "ground" wire from the "minus" terminal of the storage battery.
NOTE: The requirement to connect the wire at the maximum distance from the battery is due to the possibility of sparking when connecting.
8. Make sure you connect the cables in the correct sequence and that they do not come into contact with moving parts of the engine.
9. When using a battery installed in a donor vehicle, start the engine of that vehicle and let it idle for a few minutes until it runs smoothly.
10. Start the engine of the car with a discharged battery and let it run until it reaches a stable idle speed.
11. Disconnect the cables in the exact reverse order of their connection.
