Starting and operating
or there is one or more diagnostic trouble codes stored
in vehicle’s computer with the
“CHECK ENGINE”
warning light/MIL illuminated. A state emission inspection may reject (not pass or
fail) a vehicle if the number of OBD system readiness
monitors “Not Ready” is greater than three. Under
this condition, the vehicle operator should be instruct-
ed to drive his/her vehicle for a few days to set the
monitors and return for an emission re-inspection. Owners of rejected or failing vehicles should contact
their Subaru Dealer for service.Preparing to drive
You should perform the following checks and adjust-
ments every day before you start driving.
1. Check that all windows, mirrors, and lights are
clean and unobstructed.
2. Check the appearance and condition of the tires.
Also check tires for proper inflation.
3. Look under the vehicle for any sign of leaks.
4. Check that the hood and rear gate are fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside and outside mir-
rors.
7. Fasten your seatbelt. Check that your passengers
have fastened their seatbelts.
8. Check the operation of the warning and indicator
lights when the ignition switch is turned to the “ON” po-sition.
9. Check the gauges, indicator and warning lights af-
ter starting the engine.
NOTE
Engine oil, engine coolant, brake fluid, washer flu-
id and other fluid levels should be checked daily,
weekly or at fuel stops.

In case of emergency
Engine overheating
Never attempt to remove the radiator cap until
the engine has been shut off and has fully
cooled down. When the engine is hot, the cool-
ant is under pressure. Removing the cap while
the engine is still hot could release a spray of
boiling hot coolant, which could burn you very
seriously.
If the engine overheats, safely pull off the road and
stopthevehicleinasafeplace. If steam is coming from the engine compartment
Turn the engine off and get everyone away from the
vehicle until it cools down. If no steam is coming from the engine compartment
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compart- ment. Confirm that the cooling fan is turning. If the fan is not
turning, immediately turn the engine off and contact
your authorized dealer for repair.
3. After the engine coolant temperature has dropped,
turn off the engine.
If the temperature gauge stays at the overheated
zone, turn the engine off.
4. After the engine has fully cooled down, check the
coolant level in the reserve tank.
If the coolant level is below the “LOW” mark, add cool-
ant up to the “FULL” mark.
5. If there is no coolant in the reserve tank, add cool-
ant to the reserve tank. Then remove the radiator cap
and fill the radiator with coolant.
If you remove the radiator cap from a hot radiator, first
wrap a thick cloth around the radiator cap, then turn
the cap counterclockwise slowly without pressing
down until it stops. Release the pressure from the ra-
diator. After the pressure has been fully released, re-
move the cap by pressing down and turning it.

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
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.

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.
4. Install the under cover.
1) Filler neck
2) Fill up to this level 5. Slowly pour the coolant and fill to the radiator 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):
MT. 7.3 US qt (6.9 liters, 6.1 Imp qt)
AT. 7.2 US qt (6.8 liters, 6.0 Imp qt)
1) “FULL” level mark
2) “LOW” level mark
6. Pour the coolant and fill to the reservoir tank’s
“FULL” level mark.

Maintenance and service

Be careful not to spill engine coolant when
adding it. If coolant touches the exhaust pipe, it
may cause a bad smell, smoke, and/or a fire. Do not splash the engine coolant over paint-
ed parts. The alcohol contain ed in the engine
coolant may damage the paint surface.
1) Rubber gaskets
7. Put the radiator cap back on and tighten firmly. At
this time, make sure that the rubber gasket in the radi- ator cap is correctly in place.
8. Start and run the engine for more than five minutes
at 2,000 to 3,000 rpm.
9. Stop the engine and wait until the coolant cools
down (122 to 140
°F[50to60 °C]). If there is any loss
of coolant, add coolant to the radiator’s filler neck and
to the reserve tank’s “FULL” level.
10.Put the radiator cap and reservoir cap back on and
tighten firmly.

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 below.
Never use engine coolant as washer fluid be-
cause it could cause paint damage.
