Park your car within the length of the supplied charging cable to an outlet.
Try to utilize an outlet that is on its own circuit, or has extremely limited draw from other items on the same circuit. For instance, you will not be able to charge your car on the same circuit as your refrigerator or other high amp appliances.
Once the cord is plugged into your outlet, you may now plug into your cars charge receptacle. You will notice that you have a charge indicator on the body. That charge indicator will always light up red once the charger kicks on. The charge indicator will go from red to yellow to green depending on the state of charge.
Do not interrupt the charge cycle until the charge indicator is green.
You can leave the charge cord plugged in at all times as the charger has a built in shut-off feature once it achieves a full state of charge. However, the charger does not act as a trickle charger and once it is off it will not turn back on unless it is unplugged from the car and plugged back in to the car.
