2Maintenance and service
the materials in the vehicle may be hazardous if
improperly used or handled, for example, bat-tery acid. y
Your vehicle should only be serviced by per-
sons fully competent to do so. Serious person-
al injury may result to persons not experienced
in servicing vehicles. y Always use the proper tools and make certain
that they are well maintained. y Never get under the vehicle supported only
by a jack. Always use a safety stands to sup-
port the vehicle. y Never keep the engine running in a poorly
ventilated area, such as a garage or other
closed areas. y Do not smoke or allow open flames around
the fuel or battery. This will cause a fire. y Because the fuel system is under pressure,
replacement of the fuel filter should be per-
formed only by your SUBARU dealer.y Wear adequate eye protection to guard
against getting oil or fluids in your eyes. If
something does get in your eyes, thoroughly
wash them out with clean water. y Do not tamper with the wiring of the SRS air-
bag system or seatbelt pretensioner system, or
attempt to take its connectors apart, as that may activate the system or it can render it inop-
erative. The wiring and connectors of these
systems are yellow for easy identification. NEV-
ER use a circuit tester for these wiring.
If your SRS airbag or seatbelt pretensioner
needs service, consult your nearest SUBARU
dealer.
„ Before checking or servicing in the en-
gine compartment
yAlways stop the engine and set the parking
brake firmly to prevent the vehicle from mov-
ing. y Always let the engine cool down. Engine
parts become very hot when the engine is run-
ning and remain hot for some time after the en-
gine is stopped.y Do not spill engine oil, engine coolant, brake
fluid or any other fluid on hot engine compo-
nents. This may cause a fire.y Always remove the key from the ignition
switch. When the ignition switch is in the “ON”
position, the cooling fan may operate suddenly

even when the engine is stopped.
„ When you do checking or servicing in
the engine compartment while the en-
gine is running
A running engine can be dangerous. Keep your
fingers, hands, clothing, hair and tools away
from the cooling fan, belts and any other mov-
ing engine parts. Removing rings, watches and
ties is advisable.
Engine hood
To open the hood:
1. If the wiper blades are lifted off the windshield, re-
turn them to their original positions.
2. Pull the hood release knob under the instrument
panel.

Cooling system
Never attempt to remove the radiator cap until
the engine has been shut off and has cooled
down completely. Since the coolant is under
pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap is re-
moved.
yThe cooling system has been filled at the fac-
tory with a high quality, corrosion-inhibiting,
year-around coolant which provides protection
against freezing down to –33 °F (–36 °C). For
adding, use genuine SUBARU coolant or an
equivalent: a mixture of 50% soft water and 50%
ethylene-glycol basis coolant. Use of improper
coolants may result in corrosion in the cooling
system. It is important to maintain protection
against freezing and corrosion, even if freezing
temperatures are not expected. Never mix dif-
ferent kinds of coolant. y Do not splash the engine coolant over paint-

ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
„ Hose and connections
Your vehicle employs an electric cooling fan which is
thermostatically controlled to operate when the engine
coolant reaches a specific temperature.
If the radiator cooling fan does not operate even when
the engine coolant temperature gauge exceeds the
normal operating range, the cooling fan circuit may be
defective. Check the fuse and replace it if necessary.
If the fuse is not blown, have the cooling system
checked by your SUBARU dealer.
If frequent addition of coolant is necessary, there may
be a leak in the engine cooling system. It is recom-
mended that the cooling system and connections be
checked for leaks, damage, or looseness. „

T Checking the coolant level
1) “FULL” level mark
2) “LOW” level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside of the reser-
voir while the engine is cool.
2. If the level is close to or lower than the “LOW” level
mark, add coolant up to the “FULL” level mark. If the
reserve tank is empty, remove the radiator cap and re-
fill as required.
