- Shut off the ignition in both cars.
- Make sure that all big power consumers (such as light, radio, air conditioning etc.) are turned off in both cars.
- Attach one end of the red cable to the positive (+) battery terminal of the dead battery. You will recognize it by the + sign and a red protective cap.
- Connect the other end to the positive terminal of the functioning battery.
Please note: if the battery is not located in the motor compartment then you may use the respective pole connections in the motor compartment instead. - Attach one end of the black cable to the negative (-) terminal of the functioning battery.
- Connect the other end of the black cable to a free, unpainted metal surface of the car with the dead battery.
- Check that none of the cables touches the ventilator, V-belt or cam belt. You do not want to risk damaging them while starting your car!
- Start the donor vehicle. Then try to start the car with the empty battery.
-> If your car will not start after a few seconds then try again after a short break.
->If the jump works, do not turn off your car. Now, switch on big power consumers (light, rear window heater) in the donor car, to prevent any damages to avionics. Due to the dead battery, power spikes could arise. - Remove the black cable from both cars, then the red one.
- Take a short drive to recharge your battery!
You might know this situation: your car battery is dead and you know that you have to jump-start your car. You have a set of jumper cables ready – but you are not sure which one to attach first.
The right order: First red, then black. That’s how you get your power back.
Please follow this short instruction, to bring your car battery back to life!
Important: before you try to jump-start your car, make sure that both cars (your car with the dead battery and the functioning car that you need to jump-start yours) have the same voltage! Generally, that means either 12V or 24V. You should not use jumper cables to connect different voltage systems, as this may cause damage.
