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

genuine Subaru air cleaner.

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

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.
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.
Your Impreza WRX STI 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.
