1999 GMC Suburban Owner's Manual - Page 265

yellowblue If your Suburban has a jack cover, lift the tab up to release the cover, then take it off. To take the jack out, turn the wing nut counterclockwise and take it and the retainer off. Take the jack and storage box out and take the tools out of the box. Your vehicle may have a pair of emergency gloves secured to the jack. You can use them when changing the tire, or during other emergency situations. Remember to replace them with the jack, so you will have them if needed later. The tools you'll be using include the jack (A), the jack handle extension (B), jack handle (C), wheel wrench (D) and the ratchet (E). The jack handle extension is used if the flat tire is on the rear of the vehicle. 5-23
