yellowblue Storing the Spare Tire and Tools CAUTION: Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place. The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See "Compact Spare Tire" in the Index. See the storage instructions label to replace your compact spare in your trunk properly. Be sure to calibrate your check tire pressure system after you replace your compact spare tire with a full-sized one. See "Check Tire Pressure Light" in the Index. When storing a full-size tire, you must use the extension to help avoid wheel surface damage. Use the extension and protector/guide located in the foam holder. To store a full-size tire, place the tire in the trunk valve stem facing down, with the protector/guide through a wheel bolt hole. Remove the protector and attach the retainer securely. When reinstalling the compact spare, put the protector/guide back in the foam holder. Store the cover as far forward as possible. 5-31
