The procedure for attaching and for removing the jumper cables is described below. Perform each of the following steps only in the order described, which follow the letters shown in the illustration
⇒ fig. 183 A – B – C – D.
Attaching jumper cables
1. Switch off the ignition in both vehicles ⇒ page 205, Starting and stopping the electric drive.
2. Open the battery cover in the electric motor compartment if the battery has a cover ⇒ 12 Volt vehicle battery.
3. Attach one end of the red jumper cable to the positive terminal (+) of the dead battery: (1) ⇒ .
4. Attach the other end of the red jumper cable to the positive terminal (+) of the good battery (booster battery): (2).
5. Attach one end of the black jumper cable to the negative jump-start terminal ⇒ Jump-start termi-nal, or if that is not available, to the negative terminal (-) of the battery in the vehicle providing
assistance (2) ⇒ fig. 183.
6. Attach the other end of the black jumper cable (3) to the negative jump-start terminal ⇒ Jump-start terminal, or if that is not available, a bare metal part of the vehicle with the dead battery. This part should be connected directly to the electric motor block. You may also attach the cable to the
electric motor block itself or to the towing eye installed on the front of the vehicle ⇒ page 408, Tow-
ing. Attach the clamp to a point that is as far away as possible from the dead battery (1) ⇒ .
7. Route the jumper cables so that they cannot get caught in any moving parts in the electric motor compartment of either vehicle.
Starting the electric motor
x Start the engine of the vehicle with the good battery that is providing help and let it run at idle speed.
x Turn on the ignition of your vehicle with the dead battery. If the electric motor can be activated, wait
2 to 3 minutes before removing the jumper cables as described below ⇒ . If the electric motor cannot be activated within about 10 seconds, turn off the ignition and wait at least 1 minute; then try again.
Before removing the jumper cables
x Switch off the headlights (if they are on).
x In the vehicle with the dead battery, switch on the heater fan and the rear window defroster. This helps to minimize voltage spikes when the cables are disconnected.
Removing jumper cables
With the electric motor activated, remove the jumper cables in reverse order to the way they were connected.
1. Disconnect the black (-) cable from the vehicle with the dead battery.
2. Disconnect the black (-) cable from the other vehicle (vehicle with the good battery).
3. Disconnect the red (+) cable from the other vehicle (vehicle with the good battery).
4. Disconnect the red (+) cable from the vehicle with the dead battery.
5. Close the battery cover.
6. If necessary, unscrew the towing eye on the front of the vehicle ⇒ Installing the front towing eye.
