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.
Driver Control Center
Differential (DCCD)
(Impreza WRX STI only)
This system adjusts the torque-distribution
ratio between the front and rear wheels
of the center differential to suit driving and
road surface conditions. The DCCD can be
operated automatically or manually. When
the system is in the automatic mode, the

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.
Front Fender Vents
The front fender has functional side vents that increase
air flow through the engine compartment. This provides
additional cooling for the intercooler and engine.
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.
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.
