Screw on the wheel nut covers with your fingers, then tighten one-quarter turn with the wheel wrench. Do not try to put a wheel cover on your compact spare tire. It will not fit. Store the wheel cover and lug nut caps in the trunk until you have the flat tire repaired or replaced. Notice: Wheel covers will not fit on your compact spare. If you try to put a wheel cover on the compact spare, you could damage the cover or the spare. {CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See "Capacities and Specifications" in the Index for wheel nut torque specification. Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See "Capacities and Specifications" in the index for the wheel nut torque specification. Storing the Flat Tire and Tools {CAUTION: Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury.

After you have put the compact spare tire on your vehicle, you will need to store the flat tire in your trunk. Store the flat tire as far forward in the trunk as possible. Store the jack and wheel wrench in their compartment in the trunk. For storage, the jack must be raised until the screw end is flush with the edge of the jack. 5-85
