How to Jump Start a Ford Focus Electric

1. Park the two vehicles so that they do not touch each other.
2. Switch off the electric motor and all electrical equipment.
3. Connect the positive (+) terminal of vehicle B to the positive (+) terminal of vehicle A with cable C.
4. Connect the negative (-) terminal of vehicle B to the ground connection of vehicle A with cable D.
5. Run the engine of vehicle B at a moderately high speed, and put vehicle A's selector lever in P.
6. Switch on the ready to drive mode on vehicle A, then run both vehicles at least three minutes before disconnecting the cables in reverse order.

• Never connect directly to the negative (–) terminal of the low charge battery; a spark may cause an explosion.
• Keep cables clear of moving parts.
• Do not switch the headlamps on when disconnecting the cables; the peak voltage could blow the bulbs.
