Emergency starting

If the battery is flat, the battery of another vehicle can be used for starting and as an external power supply with the help of jumper cables. Both batteries must be 12 V batteries. The capacity (Ah) of the donor battery must not be substantially less than that of the flat battery. The flat battery must be connected correctly to the vehicle’s electrical system.

  1. Please see chapter "Battery" on page 69.

Eye or Skin Contact

  • If you get electrolyte, which is an acid, in your eyes or on your skin, immediately rinse with cold water for several minutes.

Unsuitable jumper cables and following incorrect procedures
Starting the vehicle using unsuitable jumper cables or following incorrect procedures can cause short circuits. The short circuit can cause a fire.

  • Use only standard jumper cables with sufficient cross section and completely insulated clamps. Follow the instructions provided by the jumper cable manufacturer.
  • The vehicles must not touch, otherwise current may flow as soon as the positive terminals are connected.
  • Ensure that conductive jewelery (rings, chains, watch straps) does not come into contact with live parts of the vehicle.
  • Never connect jumper cables directly to the battery. Always connect jumper cables to the emergency starting terminals.

Charging a frozen battery
There is a risk of explosion and chemical burns when charging a frozen battery.

  • It is important to thaw out a frozen battery before attaching jumper cables.

Corrosive battery acid
Lead-acid batteries contain corrosive battery acid that can be harmful to skin and damage clothing upon contact.

  • Do not lean over the battery.

  1. Open the hood.
  2. Open the cap on the positive terminal for emergency starting (+).
  3. Connect the red positive cable to the positive terminal A of the flat battery.
  4. Connect the red positive cable to the positive terminal of the donor battery.
  5. Connect the black negative cable to the negative terminal of the donor battery.
  6. Connect the black negative cable to the ground point B .
  7. Allow the engine of the donor vehicle to run at a higher engine speed.
  8. Start the engine. An attempted start using jumper cables should not last more than 15 seconds. Then wait for at least one minute.
  9. With engine running: Disconnect the black negative cable from the ground point B first, then from the negative terminal of the donor battery.
  10. With engine running: Disconnect the red positive cable from the positive terminal of the donor battery first, then from the positive terminal A of the flat battery.
  11. Close the cap on the positive terminal A for emergency starting.
