Tires The factory-fitted tires on your vehicle are summer tires. Summer tires are high-speed capability tires best suited for highway driving under dry conditions. Summer tires are inadequate for driving on slippery roads, such as on snow-covered or icy roads. If you drive your vehicle on snow-covered or icy roads, we strongly recommend the use of winter (snow) tires for all four wheels. Please note that these originally equipped summer tires offer advanced grip performance and will wear out quicker than ordinary tires. 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 weight should cause it to close securely.

make a vibration or noise when the vehicle is in tight turns at slow speeds (torque binding). In addition, if the rear differential oil exceeds a certain temperature, the DCCD will automatically cancel the current torque-distribution ratio setting and adopt its minimum ratio. Gauges G ges Gau Limited Slip Differential (Impreza WRX STI only) The Limited Slip Differential (LSD) 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 Differential, the rear differential gears may make a vibration and/or noise when making turns. When servicing the LSD, use only specified gear oil.
