Connecting jumper cables

Always connect the jumper cables in the correct order, so that no sparks 
which could cause injury occur at the battery.

1. Pull the cap of the BMW jump-starting connection up to remove.
2. Attach one terminal clamp of the plus⁄+ jumper cable to the positive 
terminal of the battery or a starting-aid terminal of the vehicle 
providing assistance.
3. Attach the second terminal clamp of the plus⁄+ jumper cable to the 
positive terminal of the battery or a starting-aid terminal of the 
vehicle to be started.
4. Attach one terminal clamp of the minus⁄– jumper cable to the negative 
terminal of the battery or to an engine or body ground of the assisting 
vehicle. Your BMW has a special nut as body ground or negative pole.
5. Attach the second terminal clamp of the minus⁄– jumper cable to the 
negative terminal of the battery or to the engine or body ground of the 
vehicle to be started.


Starting the engine
1. Start the engine of the donor vehicle and allow it to run for a few 
minutes at an increased idle speed.
2. Start the engine on the other vehicle in the usual way. If the first 
start attempt is not successful, wait a few minutes before another 
attempt in order to allow the discharged battery to recharge.
3. Let the engines run for a few minutes.
4. Disconnect the jumper cables by reversing the above connecting sequence
