Limited slip differential (LSD) (STI)
The LSD provides optimum distribution of power according to the difference in revolutions between the right and left wheels that may be caused by certain driving conditions, thereby improving driving stability on snow-covered, muddy or other slippery roads or when high speed driving.

• Never start the engine while a tire on one side is jacked up, as the vehicle may move.
• If one tire is spinning in mud, avoid continued spinning at high speed as this could adversely affect the LSD.
• If you use a temporary spare tire to replace a flat tire, be sure to use the original temporary spare tire stored in the vehicle. Using other sizes will adversely affect the LSD.
