&Warranties and maintenanceSUBARU warranties do not apply to
vehicle damage or malfunction caused by
trailer towing. If you use your vehicle to tow
a trailer, more frequent maintenance will
be required due to the additional load.
(Refer to“Maintenance schedule under
severe driving conditions”in the“Warranty
and Maintenance Booklet”.)
Under no circumstances should a trailer be
towed with a new vehicle or a vehicle with
any new powertrain component (engine,
transmission, differential, wheel bearings,
etc.) for the first 1,000 miles (1,600 km) of
driving.
&Maximum load limits
WARNING
Never exceed the maximum load
limits explained in the following.
Exceeding the maximum load limits
could cause personal injury and/or
vehicle damage.
CAUTION
.Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.
.Before towing a trailer, check the
trailer total weight, GVW, GAWs
and tongue load. Make sure the
load and its distribution in your
vehicle and trailer are acceptable.!Total trailer weight
Total trailer weightThe total trailer weight (trailer weight plus
its cargo load) must never exceed the
maximum total trailer weight in the follow-
ing table.

when towing a trailer in hilly
country on hot days.
.When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent when compared to normal
operation. For safety’s sake, you
should employ extra caution
when towing a trailer and you
should never drive at excessive
speeds. You should also keep the
following tips in mind:
.The braking power of the parking
brake may not be sufficient when
stronger braking power is
needed (e.g., when parking on a
steep slope while towing a trai-
ler).
!Before starting out on a trip
.Check the towing regulations for trailer
or caravan vehicles that vary by state/
region. Failure to comply with the proce-
dures set forth will not only compromise
your safety, but will also negate your
insurance coverage and/or may violate
the state road and traffic acts and regula-
tions.
.Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If any
problems are apparent, do not tow thetrailer.
.Check that the vehicle rests horizon-
tally with the trailer attached. If the vehicle
is tipped sharply up at the front and down
at 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 rating and 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’sbrake
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 oper-
ated.
–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 andbacking 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
of control.
.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 engine
revolution.
.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 your vehicle.
.Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ingsway.Crosswindscanbedueto
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and promptly begin
decelerating your vehicle at a gradual
pace.
.When passing other vehicles, consider-
able distance is required because of the
added weight and length caused by
attaching the trailer to your vehicle.

Engine overheating
WARNING
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 coolant is
under pressure. Removing the cap
while the engine is still hot could
release a spray of boiling hot cool-
ant, which could burn you very
seriously.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe
location.&If steam is coming from the
engine compartment.Turn the ignition switch to the“LOCK”/
“OFF”position and get everyone away
from the vehicle until it cools down.
.Contact an authorized SUBARU deal-
er.&If no steam is coming from the
engine compartment1. Keep the engine running at idling
speed.2. Open the engine hood to ventilate the
engine compartment. Refer to“Engine
hood”F11-5.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact an authorized
SUBARU dealer for repair.
3. After the coolant temperature high
warning light that has blinked or illumi-
nated inREDturns off, turn off the engine.
For details about the warning light, refer to
“Coolant temperature low indicator light/
Coolant temperature high warning light”
F3-16.
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 coolant up to the“FULL”mark.
NOTEFor details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-11.
5. If there is no coolant in the reserve
tank, add coolant 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 counter-
clockwise slowly without pressing downuntil it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.

needs service, consult your near-
est SUBARU dealer.
NOTESUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.&Before checking or servicing
in the engine compartment
WARNING
.Always stop the engine and apply
the parking brake firmly to pre-
vent the vehicle from moving.
.Always let the engine cool down.
Engine parts become very hotwhen the engine is running and
remain hot for some time after the

Engine oil
CAUTION
.If the level gauge cannot be
pulled out easily, twist the level
gauge right and left, then gently
pull it out. Otherwise, you may be
injured accidentally straining
yourself.
.Use only engine oil with the
recommended grade and vis-
cosity.
.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. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.&Engine oil consumptionSome engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the following conditions, oil
consumption can be increased and thus
require refilling between maintenance in-
tervals:
.When the engine is new and within thebreak-in period
.When the engine oil is of lower quality
.When the incorrect oil viscosity is used
.When engine braking is employed
(repeatedly)
.When the engine is operated at high
engine speeds (for extended periods of
time)
.When the engine is operated under
heavy loads (for extended periods of time)
.When towing a trailer
.When the engine idles for extended
periods of time
.When the vehicle is operated in stop
and go and/or heavy traffic situations
.When the vehicle is used under severe
thermal conditions
.When the vehicle accelerates and
decelerates frequently
Under these or similar conditions, you
should check your oil at least every 2nd
fuel fill-up and change your engine oil more
frequently. Different drivers in the same
car may experience different results. If
your oil consumption rate is greater than
expected, contact your authorized
SUBARU retailer who may perform a test
under controlled conditions.

CAUTION
If the level gauge cannot be pulled
out easily, twist the level gauge right
and left, then gently pull it out.
Otherwise, you may be injured acci-
dentally straining yourself.
2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.1) Full level
2) Low level
3) Approximately 1.1 US qt (1.0 liter, 0.9 Imp
qt) from low level to full level4. Pull out the oil level gauge again.
5. Check the oil levels on both sides of the
level gauge. The engine oil level must bejudged by the lowest of the two levels. If
the oil level is below the low level mark,
add oil so that the full level is reached.
CAUTION
.Be careful not to touch the engine
oil filter when removing the oil
filler cap. Doing so may result in a
burn, a pinched finger, or may
cause some other injury.
.Useonlyengineoilwiththe
recommended grade and vis-
cosity.
.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. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is
correct.NOTE.To prevent overfilling the engine oil,
do not add any additional oil above the
upper level when the engine is cold..The engine low oil level warning light
may stay illuminated when the engine
is started straight after topping up or
changing the engine oil. In such cases,
park the vehicle on a level surface and
wait for more than a minute until the oil
level settles, after which the warning
light will turn off. Refer to“Engine low
oil level warning light”F3-18.
&Changing the oil and oil filterChange the oil and oil filter according to
the maintenance schedule in the“War-
ranty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in
the maintenance schedule when driving
on dusty roads, when short trips are
frequently made, or when driving in ex-
tremely cold weather.NOTE.Changing the engine oil and oil filter
should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil filter.
Fully trained mechanics are on standby
at a SUBARU dealer to utilize the
special tools, spare parts and recom-
mended oil for this work, and also, used
oils are properly disposed of.

type, the maintenance interval is
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-
nectionsYour 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 coolant temperature high
warning light blinks or illuminates inRED,
the cooling fan circuit may be defective.
Refer to“Coolant temperature low indica-
tor light/Coolant temperature high warning
light”F3-16.
Check the fuse and replace it if necessary.
Refer to“Fuses”F11-34 and“Fuse panel
located in the engine compartment”F12-
12.
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 coolingsystem. It is recommended that the cooling
system and connections be checked for
leaks, damage, or looseness.
&Engine coolant!Checking the coolant level
WARNING
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 removed.
1)“FULL”level mark
2)“LOW”level markCheck the coolant level at each fuel stop.
1. Check the coolant level on the outside
