ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
„ Cooling fan, 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. „
Engine coolant
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.

Turbo models
1) Filler neck
2) Fill up to this level
5. Slowly pour the coolant and fill up to just below the
filler neck, allowing enough room to add genuine
Subaru cooling system conditioner in the radiator. Add
genuine Subaru cooling system conditioner until the
coolant level reaches the filler neck. Do not pour the
coolant too quickly, as this may lead to insufficient air
bleeding and trapped air in the system.
Guideline of coolant quantity (including coolant in reservoir
tank): Non-turbo models: MT. 7.4 US qt (7.0 liters, 6.2 Imp qt)

Brake fluid „
Checking the fluid level
1) “MAX” level mark
2) “MIN” level mark
Check the fluid level monthly.
Check the fluid level on the outside of the reservoir. If
the level is below “MIN”, add the recommended brake
fluid to “MAX”.
Use only brake fluid from a sealed container.
y Brake fluid absorbs moisture from the air.
Any absorbed moisture can cause a dangerous
loss of braking performance. y If the vehicle requires frequent refilling, there
may be a leak. If you suspect a problem, have
the vehicle checked at your SUBARU dealer.
y Never use different brands of brake fluid to-
gether. y When adding brake fluid, be careful not to al-
low any dirt into the reservoir. y Never splash the brake fluid over painted sur-
faces or rubber parts. Alcohol contained in the
brake fluid may damage them.

Windshield washer fluid
Check the level of the washer fluid at each fuel stop. If
the level is low, fill the fluid up to the neck of the reser- voir.
Use windshield washer fluid. If windshield washer fluid
is unavailable use clean water.
In areas where water freezes in winter, use an anti-
freeze type windshield washer fluid. SUBARU Wind-
shield Washer Fluid contains 58.5% methyl alcohol
and 41.5% surfactant, by volume. Its freezing temper-
ature varies according to how much it is diluted, as in-
dicated in the following table.
Never use engine coolant as washer fluid be-
cause it could cause paint damage.
