Operating
Front Hood and Hood ScoopDue 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 VentsThe 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.
TiresThe 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.

the fan does not operate during engine
warm-up until the engine coolant tem-
perature exceeds approximately 1228 F
(50 8C).
& Temperature control dialThis dial is used to set the desired interior
temperature. With the dial set to your
desired temperature, the system automa-
tically adjusts the temperature of air
supplied from the outlets such that the
desired temperature is achieved and
maintained.
If the dial is turned fully counterclockwise, the system gives maximum cooling per-
formance. If the dial is turned fully clock-
wise, the system gives maximum heating
performance.

properly and become damaged, the sys-
tem may not be able to control the interior
temperature correctly. To avoid damaging
the sensors, observe the following pre-
cautions.
– Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows.
– Solar sensor: beside the windshield
defroster grille.
– Interior air temperature sensor: near
the ignition switch.
– Outside temperature sensor: behind
the front grille.
Operating tips for heater and
air conditioner& Cleaning ventilation grilleAlways keep the front ventilation inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept clean
because cooling performance is impaired
by any accumulation of insects and leaves
on the condenser.&Efficient cooling after parking
in direct sunlightAfter parking in direct sunlight, drive with
the windows open for a few minutes to
allow outside air to circulate into the heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of
the air conditioner for maximum cooling
efficiency.
&
Lubrication oil circulation in
the refrigerant circuitOperate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil.&Checking air conditioning
system before summer sea-
sonCheck the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer.&Cooling and dehumidifying in
high humidity and low tem-
perature weather conditionsUnder certain weather conditions (high
relative humidity, low temperatures, etc.) a
small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate
any problem with the air conditioning

. Jump starting is dangerous if it
done incorrectly. If you are un-
sure about the proper procedure
for jump starting, consult a com-
petent mechanic.
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables.
& How to jump start1. Make sure the booster battery is 12
volts and the negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not let the two vehicles touch.
3. Turn off all unnecessary lights and
accessories.
4. Connect the jumper cables exactly in
the sequence illustrated.
