Pump the jack handle down and back up repeatedly to begin raising your vehicle.

If this isn't practical, pause after raising the vehicle an inch or two and take a quick look to verify that the jack has made good contact with the jack point.

If necessary, lower the jack back down by slightly opening the release valve. Then close the release valve, and reposition the jack so that it makes better contact with the jack point.

Continue raising your vehicle until it reaches the desired height—high enough to allow you to put your jack stand(s) in place.
