the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable. . Check that the tire pressures are
correct.. Check that the vehicle and trailer are
connected properly. Confirm that:
–The trailer tongue is connected
properly to the hitch ball. – The trailer lights connector is con-
nected properly and trailer ’s stop lights
illuminate when the vehicle ’s brake
pedal is pressed, and that the trailer ’s
turn signal lights flash when the vehicle ’s turn signal lever is operated.
– The safety chains are connected
properly. – All cargo in the trailer is secured
safely in position.– The side mirrors provide a good
rearward field of view without a sig-
nificant blind spot.
. Sufficient time should be taken to learn
the “feel ”of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up. !
Driving with a trailer
. You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may
result in skidding or jackknifing and loss ofcontrol. . Avoid abrupt starts and sudden accel-
erations. If your vehicle has a manual
transmission, always start out in first gear
and release the clutch at moderate enginerevolution. . Avoid uneven steering, sharp turns and
rapid lane changes.. Slow down before turning. Make a
longer than normal turning radius because
the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. In
a tight turn, the trailer could hit yourvehicle. . Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and slow down
immediately but gradually. . When passing other vehicles, consid-
erable distance is required because of the
added weight and length caused by
attaching the trailer to your vehicle.
1) Left turn
2) Right turn
. Backing up with a trailer is difficult and
takes practice. When backing up with a
trailer, never accelerate or steer rapidly.
When turning back, grip the bottom of the
steering wheel with one hand and turn it to
the left for a left turn, and turn it to the right
for a right turn. . If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed
immediately by the nearest SUBARU
dealer.

Engine overheating
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
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 stop the vehicle in a safe place. & If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down. & If no steam is coming from
the engine compartment
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to “Engine coolant ”F 11-14.
1. Keep the engine running at idlingspeed. 2. Open the hood to ventilate the engine
compartment. Refer to
“Engine hood ”
F 11-5.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your SUBARU
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If any of the following conditions occur,
turn off the engine. .The temperature gauge stays in the
overheated zone (if equipped). Referto “Temperature gauge (models with
type A combination meter) ”F 3-11.
. The coolant temperature high warn-
ing light remains illuminated (if
equipped). Refer to “Coolant tempera-
ture low indicator light/Coolant tem-
perature high warning light ”F 3-16.
4. After the engine has fully cooled down,
check the coolant level in the reservoir.
If the coolant level is below the “LOW ”
mark, add coolant up to the “FULL ”mark.
5. If there is no coolant in the reservoir,
add coolant to the reservoir. Then remove
the radiator cap (non-turbo models) or the
coolant filler tank cap (turbo models) and
fill the radiator with coolant.
If you have to remove a hot radiator cap/
coolant filler tank cap, first wrap a thick cloth around the cap, then turn the cap
counterclockwise slowly without pressing
down until it stops. Release the pressure
from the cooling system. After the pres-
sure has been fully released, remove the
cap by pressing it down and turningcounterclockwise.
In case of emergency

Non-turbo models Oil filter color Part number Amount of
rotation
Black 15208AA160 1 rotation
CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If spilled oil is not promptly
wiped up, the oil could cause afire.
11. Reinstall under cover (turbo models). 12. Pour engine oil through the filler neck.
For the oil capacity guideline, refer to “
Engine oil ”F 12-5.
The oil quantity indicated above is onlyguideline.
The necessary quantity of oil depends on
the quantity of oil that has been drained.
The quantity of drained oil differs slightly
depending on the temperature of the oil
and the time the oil is left flowing out. After
refilling the engine with oil, therefore, you
must use the level gauge to confirm that
the level is correct.
13. Start the engine and make sure that no
oil leaks appear around the filter ’s rubber
seal and drain plug.
14. Run the engine until it reaches the
normal operating temperature. Then stop
the engine and wait a few minutes to allow
the oil drain back. Check the oil level
again and if necessary, add more engineoil.
CAUTION
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire.

shortened to that of the mixing coolant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con- nections
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 following conditions occur,
the cooling fan circuit may be defective. . The engine coolant temperature gauge
exceeds the normal operating range (if
equipped). Refer to “Temperature gauge
(models with type A combination meter) ”
F 3-11.
. The coolant temperature high warning
light blinks or illuminates in RED(if
equipped). Refer to “Coolant temperature
low indicator light/Coolant temperature
high warning light ”F 3-16.
Check the fuse and replace it if necessary.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer. Refer to
“Fuses ”F 11-44 and “Fuse panel
located in the engine compartment ”F 12-
13.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended 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 reservoir 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 reservoir is
empty, remove the radiator cap (non-turbo
models) or the coolant filler tank cap
(turbo models) and refill as required.
NOTE (turbo models only)
The cap (without tabs) on top of the
radiator does not need to be removed.
Remove the cap (with tabs) on the
coolant filler tank on top of the engine.
3. After refilling the reservoir and the
radiator, reinstall the caps after checking
that the rubber gaskets inside the radiator
cap/coolant filler tank cap are in the properposition.

WARNING
Never let clutch fluid contact your
eyes because clutch fluid can be
harmful to your eyes. If clutch fluid
gets in your eyes, immediately flush
them thoroughly with clean water.
For safety, wearing eye protection isadvisable.
CAUTION
. Clutch fluid absorbs moisture
from the air. Any absorbed moist-
ure can cause improper clutchoperation.
. If the vehicle requires frequent
refilling, there may be a leak. If
you suspect a problem, have the
vehicle checked at your SUBARU
dealer.
. When clutch fluid is added, be
careful not to allow any dirt into
the tank.
. Never splash the clutch fluid over
painted surfaces or rubber parts.
Alcohol contained in the clutch
fluid may damage them.
. Be careful not to spill clutch fluid
when adding it. If clutch fluid
touches the exhaust pipe, it may cause a bad smell, smoke, and/or
a fire. If clutch fluid gets on the
exhaust pipe, be sure to wipe itoff.
& Recommended clutch fluid
Refer to “Fluids ”F 12-9.
CAUTION
Never use different brands of clutch
fluid together. Also, avoid mixing
DOT 3 and DOT 4 brake fluids even if
they are the same brand. Brake booster
If the brake booster does not operate as
described in the following, have it checked
by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal should move
slightly down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for
approximately 1 minute then turn it off.
