NOTE: Before use make sure all electrical accessories are turned off.
Before starting these steps you can place your Mighty Jump in any cup holder for easy use.
Step 1: Test the Battery. Connect the cigarette lighter end of the Mighty Jump cord into the cigarette lighter socket of your vehicle. Make sure that the switch on the cigarette lighter end of the cord is in the rearward position. Then turn the key in the ignition to the accessory position, usually one quarter turn of the key. If you get a GREEN LIGHT on the cigarette lighter end of the plug continue. If not your battery may be damaged and unable to charge.
Step 2: Test Electrical System. Leaving the Mighty Jump plugged into your vehicle, turn on the headlights. Leave them on for 10-15 seconds. Turn them off. If the GREEN LIGHT on the cigarette lighter end of the plug stays on, move to Step 3. If NO GREEN LIGHT IS ON your electrical system may be damaged, professional help may be needed.
Step 3: Charging the Vehicle. Move switch to the forward position. Connect the plug end of the cord into outlet on the top of the Mighty Jump. The GREEN LIGHT will appear brighter, this means the battery is accepting the charge from the Mighty Jump. Wait 10 minutes. After 10 minutes have passed move to Step 4.
Step 4: Start the Vehicle. Now start your vehicle, do not pump the gas while you are starting your vehicle. Pumping the gas could cause engine flooding and stop the vehicle from starting.
Step 5: Charging the Mighty Jump. Charge the Mighty Jump only after your vehicle is operating, and running smoothly. With the cords still connected, push the switch on the cigarette lighter end down (rearward). The green light will be illuminated. Leave your vehicle running with the Mighty Jump plugged in for about 45 minutes.
Step 6: Storing. Once your vehicle and Mighty Jump are charged, disconnect all plugs. You can store your Mighty Jump in your glove box, trunk, or cup holder. We recommend you do not store the Mighty Jump plugged in.
