Removing the Flat Tire and Installing the Spare Tire 1. Before you start, block the front and rear of the tire farthest away from the one being changed. Then put your compact spare tire near the flat tire. 2. With the DOWN side facing you, turn the ratchet and socket to loosen all the wheel nuts counterclockwise. Don't remove them yet. 3. The jack has a bolt on the end. Attach the socket end of the extension to the jack bolt. {CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. {CAUTION: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle. 4. Attach the ratchet to the extension with the UP side facing you. 5. Turn the ratchet clockwise. That will raise the jack lift head a little. 5-80
