Attachment points for the jump leads.
When jump starting the car, the following steps are recommended to avoid short circuits or other damage:
Set the car's electrical system in ignition position 0.
Check that the donor battery has a voltage of 12 V.
If the donor battery is installed in another car - switch off the donor car's engine and make sure that the two cars do not touch each other.
Connect one of the red jump lead's clamps to the donor battery's positive terminal (1).
Connect the start cable carefully to avoid short circuits with other components in the engine compartment.
Open the positive jump-starting point's cover (2).
Connect the red jump lead's other clamp onto the car's positive jump-starting point (2).
Connect one of the black jump lead's clamps to the donor battery's negative terminal (3).
Connect the black jump lead's other clamp onto the car's negative jump-starting point (4).
Check that the jump lead clamps are affixed securely so that there are no sparks during the starting attempt.
Start the engine of the "donor car" and allow it to run a few minutes at a speed slightly higher than idle approx. 1500 rpm.
Start the engine in the car with the discharged battery.
Do not touch the connections between cable and car during the starting attempt. There is a risk of sparks forming.
Remove the jump leads in reverse order - first the black and then the red.
Make sure that none of the black jump lead's clamps comes into contact with the car's positive jump-starting point/donor battery's positive terminal or the clamp connected to the red jump lead.
- The battery can generate oxyhydrogen gas, which is highly explosive. A spark can be formed if a jump lead is connected incorrectly, and this can be enough for the battery to explode.
- Do not connect the jump leads to any fuel system component or any moving part. Be careful of hot engine parts.
- The battery contains sulphuric acid, which can cause serious burns.
- If sulphuric acid comes into contact with eyes, skin or clothing, flush with large quantities of water. If acid splashes into the eyes - seek medical attention immediately.
- Never smoke near the battery.
If the starter battery has been discharged so much that the car has no normal electrical functions and the engine is then jump-started with an external battery or a battery charger, the Start/stop function may continue to be activated. If the Start/stop function then auto-stops the engine shortly afterwards, there is a great risk that engine auto-start will fail due to insufficient battery capacity, because the battery has not had the time to recharge.
If the car has been jump-started, or if there is insufficient time to charge the battery with a battery charger, the Start/stop function is temporarily deactivated until the battery has been recharged by the car. In an outside temperature of approx. +15 °C (approx. 60 °F), the battery needs to be charged for at least 1 hour by the car. In a lower outside temperature, the charging time may increase to 3–4 hours. The recommendation is to charge the battery using an external battery charger.
