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.

1. Power Steering Fluid Reservoir Check your power steering fluid level
monthly. The power steering fluid expands
greatly as its temperature rises and
the fluid level differs according to fluid
temperature. Therefore, the reservoir tank
has two different checking ranges for
hot and cold fluid. Please refer to your
Owner’s Manual for details.
2. Air Cleaner Element This element filters intake air. Follow the

B O E . B J O U F O B O D F w C P P L M F U 8 I F O
necessary, replace this element with a
genuine Subaru air cleaner.
3. Radiator Cap If your engine overheats, safely pull off the
road and stop your vehicle in a safe place.

until the engine has been shut off and has
fully cooled down. If steam is coming from
the engine compartment, turn the engine
off and move everyone away from the
vehicle until it cools. Please refer to your
Owner’s Manual for details. 4. Intercooler
The intercooler is positioned behind
the throttle body to cool intake air and
improve supercharging efficiency. (Intake
air passing through the turbocharger gets
very warm, which could result in lower
supercharging efficiency.) To prevent
damage to this important system, avoid
placing tools and other objects on
the intercooler.
5. Engine Oil Level Gauge Check the engine oil level at each fuel
stop. Pull out the dipstick, wipe it clean,
and insert it again. Pull it out and check
the oil level. If it’s below the lower level,
add oil to bring the level up to the
upper level. (Use only engine oil of the
recommended grade and viscosity.
Please refer to your Owner’s Manual
for oil recommendations and other
important details.) 6. Engine Coolant Reservoir
Check your coolant level at each
fuel stop. Observe the coolant
level on the outside of the reservoir
while the engine is cool. If the level

tank is empty, remove the radiator
cap and refill as required. Please
refer to your Owner’s Manual for
details.

the maintenance schedule in

changed more frequently when you
drive on dusty roads, frequently
make short trips, or when you drive
in extremely cold weather.
8. Brake Fluid Reservoir Check your brake fluid level
monthly. Observe the fluid level on
the outside of the reservoir. If the

mark. Use only brake fluid from
a sealed container.
9. Battery When your vehicle does not start
due to a battery that has run down,
the vehicle may be jump-started by
connecting your battery to another
battery with jumper cables. Jump-starting is dangerous if
done incorrectly. Please refer
to your Owner’s Manual for
instructions. If you’re unsure
about how to jump-start your
vehicle, please consult a
competent mechanic.
10. Windshield Washer Tank It’s a good idea to check your washer fluid every time you stop
for fuel. If the level is low, fill the
windshield washer tank to the
neck of the reservoir with
windshield washer fluid. In cold
weather, use a freeze resistant
windshield washer fluid.
11. Main Fuse Box Your Impreza WRX has two fuse boxes. One is located under the
instrument panel, behind the
fuse box cover on the driver’s
seat side. The other is housed
in your engine compartment, as
shown here. Fuses are designed
to melt during an overload
situation in order to prevent
damage to the wiring harness and
electrical equipment. If any lights,
accessories or electrical controls
fail to operate properly, inspect
the corresponding fuse. If it has
blown, replace it in accordance
with the instructions in your
Owner’s Manual. The fuse puller
and spare fuses are located
in the main fuse box in the
engine compartment.

to OFF, OFF to ON, or the vehicle starts
moving before the setting procedure is
finished.
. Setting the speed is impossible
when the vehicle is moving.
. The set engine speed may differ
from the engine speed shown by the
tachometer. Use the engine speed
shown by the tachometer as a rough
guide.
. If the setting operation is performed
with the engine switch turned off, the
REV indicator light turns off and the
setting operation is aborted when you
have stopped the setting operation for
approximately 10 seconds.
. If the setting operation is performed
with the engine switch turned off, the
REV indicator light turns off and the
setting operation is aborted when you
open and close the driver ’s door.& Deactivating the REV alarm
systemTo deactivate the REV indicator light and
buzzer functions of the REV alarm system,
set the thousands place of the alarm-level
engine speed to “–”.
Warning and indicator lightsSeveral of the warning and indicator lights
illuminate momentarily and then turn off
when the ignition switch is initially turned
to the “ON”position. This permits check-
ing the operation of the bulbs.
Apply the parking brake and turn the
ignition switch to the “ON”position. For
the system check, the following lights
illuminate and turn off after several sec-
onds or after the engine has started:: Seatbelt warning light (The seatbelt warning light turns off
only when the driver fastens the
seatbelt.): Front passenger ’s seatbelt warning
light
