Jump-start connection point (earth) on the vehicle being jump-started .
The vehicle can be jump-started or be used to jump-start another vehicle via the earth and positive jump-start connection points.
Connect the jump leads only in the order 1 – 2 – 3 – 4 → Fig. 4.
1. Switch off the ignition in both vehicles.
2. If present, fold open the cover on the positive jump-start connection point in the bonnet space.
3. Connect one end of the red jump lead to the positive jump-start connection point of the vehicle with the discharged 12-volt
vehicle battery → Fig. 4 1 → Fig. 2.
4. Connect the other end of the red jump lead to the positive battery terminal of the vehicle providing assistance → Fig. 4 2 .
5. Connect one end of the black jump lead to an earth jump-start connection point on the vehicle with the 12-volt vehicle battery
providing assistance → Fig. 4 3 .
if no earth jump-start connection point is present, connect the end of the black jump lead to a solid metal part that is
securely bolted onto the cylinder block or to the cylinder block itself on the vehicle with the 12-volt vehicle battery providing
assistance → Fig. 4 3 .
6. Connect the other end of the black jump lead to the earth jump-start connection point on the vehicle with the discharged 12-
volt vehicle battery → Fig. 4 4 → Fig. 1.
7. Position the leads in such a way that they cannot come into contact with any moving parts in the bonnet space.
1. Start the engine of the vehicle which is providing assistance and let it run at idle.
2. Wait a few minutes and then start the engine in the vehicle with the discharged 12-volt vehicle battery. If the engine does not
start immediately, switch off the starter after about 10 seconds and try again after about 1 minute.
Please contact an expert if the vehicle’s engine still will not start.
