While Operating
Front Hood and Hood Scoop
Due to the lightweight material, a
slight vibration is normal at higher
speeds and will not affect the
durability of the hood. To avoid
deforming the front hood when
closing, do not press down on the
hood with your hands. You can
release your hold on the front hood
approximately 12 inches above
the closing position and its weight
should cause it to close securely.
Limited Slip Rear Differential (WRX STI only)
The Limited Slip Rear Differential provides optimum distribution of power according to the
difference in revolution between the right and left rear wheels that may be caused by certain
driving conditions, thereby improving driving stability on snow-covered, muddy or other
slippery roads or during high-speed driving. Due to the nature of this mechanical Limited
Slip Rear Differential, the differential gears may emit a vibration and/or noise when making
turns. When servicing, use only specified gear oil.
