Roadside Emergencies If equipped with a tether, perform the following additional steps: 6. Lift the spare tire on end to access the tether attachment. 7. Use the lug wrench to remove the lug nut from the spare tire tether. 8. If not replacing the spare or flat tire to the underbody storage area, raise the wheel retainer up into the installed position. 9. Use the attached fastener strap (on the spare tire tether) to attach the tether end to the winch retainer prior to raising to the installed position. Tire change procedure WARNING: When one of the rear wheels is off the ground, the transmission alone will not prevent the vehicle from moving or slipping off the jack, even if the transmission is in P (Park). WARNING: To prevent the vehicle from moving when you change a tire, be sure the parking brake is set, then block (in both directions) the wheel that is diagonally opposite (other side and end of the vehicle) to the tire being changed. WARNING: If the vehicle slips off the jack, you or someone else could be seriously injured. WARNING: Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid the danger of being hit when operating the jack or changing the wheel. Note: Passengers should not remain in the vehicle when the vehicle is being jacked. 332 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
