8. Tighten the wheel nuts firmly in a crisscross sequence as shown. Install the plastic nut caps and tighten by hand. Then, using the wheel wrench, tighten an additional one-quarter turn. 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. Storing a Flat or Spare Tire and Tools CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become 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 100 lb-ft (140 N·m). 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. Return the jack, wheel wrench and flat tire following the storage instructions. When you reinstall the trim panel, be sure to tuck it under the weatherstrip. 5-31
