Step 2: Connect the red clamp to the positive terminal (+) of the car
battery and connect the black clamp to the negative terminal (-) of the
car battery. If the green and red light indicators on the battery clamp are
flashing alternately, you are safe to move on to to the next step.
However, if the red indicator light is on:
1. The battery clamp may be connected in reverse. If so, you need to
disconnect the battery clamp from the vehicle and the jump starter.
2. Adjust the clamps for maximum contact with battery terminals.
Step 3-a: Start your car.
