Maintenance OCTANE RECOMMENDATIONS Your vehicle is designed to use "Premium" unleaded gasoline with an (R+M)/2 octane rating of 91 or higher for optimum performance. (R+M)/2 METHOD The use of gasolines with lower octane ratings may degrade performance. We do not recommend the use of gasolines labeled as "Premium" in high altitude areas that are sold with octane ratings of less than 91. If your engine knocks under any driving conditions while you are using fuel with the recommended octane rating, see your dealer or a qualified service technician to prevent any engine damage. 91 WHEELS AND TIRES Tires Wheels 295/45 ZR 18 BSW tires SVT-Signature style, 18 in x 9.5 in aluminum 5-spoke wheels TIRE ROTATION Because your vehicle's tires perform different jobs, they often wear differently. To make sure your tires wear evenly and last longer, rotate them as indicated in the scheduled maintenance guide. If you notice that the tires wear unevenly, have them checked. SPARE TIRE AND WHEEL Your vehicle is equipped a 235/70R-16 spare tire on a steel wheel rim. This is for temporary use only. Replace this spare tire with a repaired road tire as soon as possible. 14
