Proper balancing will reduce vibration and avoid tire cupping and spotty wear. ALL WHEEL DRIVE (AWD) - IF EQUIPPED CAUTION! All Wheel Drive (AWD) vehicles must have the same size and type tires on all wheel positions. Unequal tire sizes must not be used.

When the appropriate conditions exist, the Electronic Vehicle Information Center (EVIC) displays the following messages. 5
