Storing the Spare Tire and Tools When storing a compact spare tire in the trunk, put the protector/guide back in the foam holder. 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. When storing a full-size tire, use the extension with the protector/guide, located in the foam holder, to help avoid wheel surface damage. To store a full-size tire, place the tire valve stem facing down, and then remove the protector/guide and attach the retainer securely. Store the cover as far forward as possible. 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 return your compact spare to your trunk properly. Be sure to calibrate your low tire pressure system after you replace your compact spare tire with a full-sized one. See "Low Tire Inflation Monitor" in the Index. 5-32
