Place the dust cap over the four-pin connector of the
hitch wire harness to protect against possible damage.y Occasionally lubricate terminals of the four-pin con-
nector using the terminal grease.Trailer towing
Your car is designed and intended to be used primarily
as a passenger-carrying vehicle. Towing a trailer puts
additional loads on your car’s engine, drivetrain,
brakes, tires and suspension and has an adverse ef-
fect on fuel economy.
If you do decide to tow a trailer, your safety and satis-
faction depend upon proper use of correct equipment
and cautious operation of your vehicle. Seek the ad-
vice of your SUBARU dealer to assist you in purchas-
ing a hitch and other necessary towing equipment ap-
propriate for your vehicle. In addition, be sure to follow
the instructions on correct installation and use provid-
ed by the trailer and other towing equipment manufac- turers.
SUBARU assumes no responsibility for injuries or ve-
hicle damage that result from trailer towing equipment,
or from any errors or omissions in the instructions ac-
companying such equipment or for your failure to fol-
low the proper instructions. „ Warranties and maintenance
SUBARU 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 “Main-

tenance 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
Never exceed the maximum load limits ex-
plained below. Exceeding the maximum load
limits could cause personal injury and/or vehi-
cle damage.
yAdequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. y 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.
T Total trailer weight
Total trailer weight
The total trailer weight (trailer weight plus its cargo
load) must never exceed the maximum weight shown
below.

In case of emergency

Temporary spare tire
Never tow a trailer when the temporary spare
tire is used. The temporary spare tire is not de-
signed to sustain the towing load. Use of the
temporary spare tire when towing can result in
failure of the spare tire and/or less stability of
the vehicle and may lead to an accident.
Never use any temporary spare tire other than
the original. Using other sizes may result in se-
vere mechanical damage to the drive train of
your vehicle.
The temporary spare tire is smaller and lighter than a
conventional tire and is designed for emergency use
only. Remove the temporary spare tire and re-install
the conventional tire as soon as possible because the
spare tire is designed only for temporary use.
Check the inflation pressure of the temporary spare
tire periodically to keep the tire ready for use. The cor- rect pressure is
60 psi (420 kPa, 4.2 kg/cm 2
).
When using the temporary spare tire, note the follow-
ing: y Do not exceed 50 mph (80 km/h).
y Do not put a tire chain on the temporary spare tire.
Because of the smaller tire size, a tire chain will not fit
properly. y Do not use two or more temporary spare tires at the
same time. y Do not drive over obstacles. This tire has a smaller
diameter, so road clearance is reduced.

Appearance care
– CONTINUED –
Mud and sand adhering to the underbody components
may accelerate their corrosion.
After driving off-road or muddy or sandy roads, wash
the mud and sand off the underbody.
Carefully flush the suspension and axle parts, as they
are particularly prone to mud and sand buildup. Do not
use a sharp-edged tool to remove caked mud.
NOTE
Be careful not to damage brake hoses, sensor har-
nesses, and other parts when washing suspen-
sion components. TUsing a warm water washer
y Keep a good distance of 12 in (30 cm) or more be-
tween the washer nozzle and the vehicle. y Do not wash the same area continuously.
y If a stain will not come out easily, wash by hand.
Some warm water washers are of the high tempera-
ture, high pressure type, and they can damage or de-
form the resin parts such as mouldings, or cause wa-
ter to leak into the vehicle. „ Waxing and polishing
Always wash and dry the vehicle before waxing and
polishing.
Use a good quality polish and wax and apply them ac- cording to the manufacturer’s instructions. Wax or pol-
ish when the painted surface is cool.
Be sure to polish and wax the chrome trim, as well as
the painted surfaces. Loss of wax on a painted surface
leads to loss of the original luster and also quickens
the deterioration of the surface. It is recommended
that a coat of wax be applied at least once a month, or
whenever the surface no longer repels water.
If the appearance of the paint has diminished to the
point where the luster or tone cannot be restored,
lightly polish the surface with a fine-grained com-
pound. Never polish just the affected area, but include
the surrounding area as well. Always polish in only
one direction. A No. 2000 grain compound is recom-
mended. Never use a coarse-grained compound.
Coarser grained compounds have a smaller grain-size
number and could damage the paint. After polishing
with a compound, coat with wax to restore the original
luster. Frequent polishing with a compound or an in-
correct polishing technique will result in removing the
paint layer and exposing the undercoat. When in
doubt, it is always best to contact your SUBARU deal-
er or an auto paint specialist.
NOTE
Be careful not to block the windshield washer noz-
zles with wax when waxing the vehicle.

2Maintenance and service
wait a few minutes for the oil to drain back into the oil
pan before checking the level.
To prevent overfilling the engine oil, do not add any
additional oil above the upper level when the engine is cold.
In 2.5-liter-engine models, the dipstick has a notch
above the upper level.
Just after driving or while the engine is warm, the en-
gine oil level reading may be in a range between the
upper level and the notch mark. This is caused by ther-
mal expansion of the engine oil. „
Changing the oil and oil filter
Change the oil and oil filter according to the mainte-
nance schedule in the “Warranty and Maintenance
Booklet”.
The engine oil and oil filter must be changed more fre-
quently than listed in the maintenance schedule when
driving on dusty roads, when short trips are frequently
made, or when driving in extremely cold whether.
1. Warm up the engine by letting the engine idle for
about 10 minutes to ease draining the engine oil.
2. Park the vehicle on a level surface and stop the en-
gine.
3. Remove the oil filler cap. 1) Drain plug
4. Drain out the engine oil by removing the drain plug
while the engine is still warm. The used oil should be
drained into an appropriate container and disposed of
properly.
Be careful not to burn yourself with hot engine
oil.

7. Slide the cover toward the vehicle front to remove it.
8. Remove the oil filter with an oil filter wrench.
9. Before installing a new oil filter, apply a thin coat of
engine oil to the seal.
10.Clean the rubber seal seating area of the bottom of
engine and install the oil filter by hand turning. Be
careful not to twist or damage the seal.
11.Tighten it approximately two-thirds of a turn after
the seal makes contact with the bottom of engine.
Never over tighten the oil filter because that can
result in an oil leak.
12.Reinstall the cover under the oil filter.
13.Pour engine oil through the filler neck.
Oil capacity (Guideline): 2.5 liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
3.0 liter models: 5.6 US qt (5.3 liters, 4.6 Imp qt)
The oil quantity indicated above is only a guideline.
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 dipstick to
confirm that the level is correct.
14.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal and drain plug.
15.Run the engine until it reaches the normal operat-
ing 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 engine oil.
