How to Jump Start a MINI Hardtop 2 Door

1. Check that the other vehicle's battery is 12 volts, switch off its engine, and switch off power consumers in both vehicles.
2. Open the covers of the jump-start terminals in the engine compartment.
3. Clamp the positive cable to the positive terminal of the helping vehicle, then to the positive terminal of the vehicle being started.
4. Clamp the negative cable to the negative terminal or engine/body ground of the helping vehicle.
5. Attach the other end of the negative cable to the negative terminal or engine/body ground of the vehicle being started.
6. Start the donor vehicle's engine and let it run for several minutes at increased idle speed, then start the other engine as usual.
7. Let both engines run for several minutes, then disconnect the jumper cables in reverse order.

• Use only jumper cables with fully insulated clamp handles, and make sure the vehicles do not touch each other.
• If the first start attempt fails, wait a few minutes before trying again.
• Never use spray fluids to start the engine; check and recharge the battery afterward if needed.
