How do I use the built-in compressor to inflate tires?

Ensure the jump starter is fully charged, screw the Sure Fit® nozzle onto the valve stem of the tire, and press the Compressor Power Button to turn on the compressor. Use the Increase (+) and Decrease (–) Pressure Control Buttons to set your desired pressure—the compressor will automatically stop when the set pressure is reached. Press the Compressor Power Button again to turn off the unit and remove the nozzle.
