If the starter battery is discharged then the car can be started with current from another battery.
When jump starting the car, the following steps are recommended to avoid short circuits or other damage:
Set the car's electrical system in key position 0, see Key positions.
- 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.
- 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.
