WARNING
Do not connect safety chains to part
of the vehicle other than the safety
chain hooks.
Hitch harness connector
8. Connect the hitch wire harness ’s black
four-pin wire connector to the towing trailer ’s wire harness.
9. Confirm proper function of the hitch
wire harness by individually activating the
brake, right turn signal, left turn signal,
stop, and parking lights on the trailer. NOTE
Always disconnect the trailer wire har-
ness before launching or retrieving a watercraft.
& When you do not tow a trailer
. Remove the ball mount from the hitch
receiver tube and insert the receiver cover
onto the hitch receiver tube. . Place the dust cap over the four-pin
connector of the hitch wire harness to
protect against possible damage. . Occasionally lubricate terminals of the
four-pin connector using the terminal grease. Trailer towing
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle
’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety
and satisfaction depend upon proper use
of correct equipment and cautious opera-
tion of your vehicle. Seek the advice of
your SUBARU dealer to assist you in
purchasing a hitch and other necessary
towing equipment appropriate for your
vehicle. In addition, be sure to follow the
instructions on correct installation and use
provided by the trailer and other towing
equipment manufacturers.
SUBARU assumes no responsibility for
injuries or vehicle damage that result from
trailer towing equipment, or from any
errors or omissions in the instructions
accompanying such equipment or for your
failure to follow 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. Driving tips

Certification label
! Gross Axle Weight (GAW) and
Gross Axle Weight Rating (GAWR)
Gross Axle Weight The total weight applied to each axle
(GAW) must never exceed the Gross Axle
Weight Rating (GAWR). The front and rear
GAWs can be adjusted by relocating
passengers and luggage inside the vehi-
cle. The front and rear GAWR are also
shown on the certification label.
Certification label
To check both GVWR and GAWR and to
confirm that the total weight and weight
distribution are within safe driving limits,
you should have your vehicle and trailer
weighed at a commercial weighing station.
Be sure that all cargo is firmly secured to
prevent a change in weight distribution
while driving. !
Tongue load
Tongue load
WARNING
If the trailer is loaded with more
weight in the back of trailer ’s axle
than in the front, the load is taken off
the rear axle of the towing vehicle.
This may cause the rear wheels to
skid, especially during braking or
when vehicle speed is reduced dur-
ing cornering, resulting in over-
steer, spin out and/or jackknifing.
Ensure that the trailer tongue load is from
8 to 11 percent of the total trailer weight
and does not exceed the maximum value
of 200 lbs (90 kg).

10-2Appearance care
Exterior care &Washing
CAUTION
. When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance will
be longer. To dry the brakes,
drive the vehicle at a safe speed
while lightly pressing the brake
pedal to heat up the brakes.
. Do not wash the engine compart-
ment and areas adjacent to it. If
water enters the engine air in-
take, electrical parts or the power
steering fluid reservoir, it will
cause engine trouble or faulty
power steering respectively. .
Since your vehicle is equipped
with a rear wiper, automatic car-
wash brushes could become
tangled around it, damaging the
wiper arm and other compo-
nents. Ask the automatic car-
wash operator not to let the
brushes touch the wiper arm or
to fix the wiper arm on the rear
window glass with adhesive tape
before operating the machine.
(Station wagon models only)
NOTE
When having your vehicle washed in
an automatic car wash, make sure
beforehand that the car wash is of
suitable type.
The best way to preserve your vehicle ’s
beauty is frequent washing. Wash the
vehicle at least once a month to avoid
contamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash
the vehicle with hot water and in directsunlight.
Salt, chemicals, insects, tar, soot, tree
sap, and bird droppings should be washed
off by using a light detergent, as required.
If you use a light detergent, make certain that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly
flushed from the surface and not allowed
to dry there. Rinse the vehicle thoroughly
with plenty of lukewarm water. Wipe the
remaining water off with a chamois or softcloth. !
Washing the underbody
Chemicals, salts and gravel used for
deicing road surfaces are extremely cor-
rosive, accelerating the corrosion of un-
derbody components, such as the exhaust
system, fuel and brake lines, brake
cables, floor pan and fenders, and sus-pension.
Thoroughly flush the underbody and in-
side of the fenders with lukewarm or cold
water at frequent intervals to reduce the
harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-sion.
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.

10-4Appearance care
Corrosion protection
Your SUBARU has been designed and
built to resist corrosion. Special materials
and protective finishes have been used on
most parts of the vehicle to help maintain
fine appearance, strength, and reliableoperation. &Most common causes of corrosion
The most common causes of corrosion are:
1. The accumulation of moisture retain-
ing dirt and debris in body panel sections,
cavities, and other areas.
2. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor accidents.
Corrosion is accelerated on the vehicle when:
1. It is exposed to road salt or dust
control chemicals, or used in coastal
areas where there is more salt in the air,
or in areas where there is considerable
industrial pollution.
2. It is driven in areas of high humidity,
especially when temperatures range just
above freezing.
3. Dampness in certain parts of the
vehicle remains for a long time, even though other parts of the vehicle may be
dry.
4. High temperatures will cause corro-
sion to parts of the vehicle which cannot
dry quickly due to lack of proper ventila-tion.
& To help prevent corrosion
Wash the vehicle regularly to prevent
corrosion of the body and suspension
components. Also, wash the vehicle
promptly after driving on any of the
following surfaces: . roads that have been salted to prevent
them from freezing in winter. mud, sand, or gravel
. coastal roads
After the winter has ended, it is recom-
mended that the underbody be given a
very thorough washing.
Before the beginning of winter, check the
condition of underbody components, such
as the exhaust system, fuel and brake
lines, brake cables, suspension, steering
system, floor pan, and fenders. If any of
them are found to be rusted, they should
be given an appropriate rust prevention
treatment or should be replaced. Contact
your SUBARU dealer to perform this kind
of maintenance and treatment if you need assistance.
Repair chips and scratches in the paint as
soon as you find them.
Check the interior of the vehicle for water
and dirt accumulation under the floor mats
because that could cause corrosion.
Occasionally check under the mats to
make sure the area is dry.
Keep your garage dry. Do not park your
vehicle in a damp, poorly ventilated
garage. In such a garage, corrosion can
be caused by dampness. If you wash the
vehicle in the garage or put the vehicle
into the garage when wet or covered with
snow, that can cause dampness.
If your vehicle is operated in cold weather
and/or in areas where road salts and other
corrosive materials are used, the door
hinges and locks, trunk lid lock, and hood
latch should be inspected and lubricated
periodically.

11-32Maintenance and service
&Checking the clutch pedal
free play
1) 0.02 –0.08 in (0.5 –2.0 mm)
Lightly press the clutch pedal down with
your finger until you feel resistance, and
check the free play.
If the free play is not within proper
specification, contact your SUBARU deal-
er. Replacement of brake pad
and lining
CAUTION
If you continue to drive despite the
scraping noise from the audible
brake pad wear indicator, it will
result in the need for costly brake
rotor repair or replacement.
The right front disc brake and the right rear
disc brake have audible wear indicators
on the brake pads. If the brake pads wear
close to their service limit, the wear
indicator makes a very audible scraping
noise when the brake pedal is applied.
If you hear this scraping noise each time you apply the brake pedal, have the brake
pads serviced by your SUBARU dealer as
soon as possible. &
Breaking-in of new brake
pads and linings
When replacing the brake pad or lining,
use only genuine SUBARU parts. After
replacement, the new parts must be
broken in as follows: ! Brake pad and lining
While maintaining a speed of 30 to 40
mph (50 to 65 km/h), step on the brake
pedal lightly. Repeat this five or moretimes. ! Parking brake lining
WARNING
A safe location and situation should
be selected for break-in driving.
CAUTION
Pulling the parking brake lever too
forcefully may cause the rear
wheels to lock. To avoid this, be
certain to pull the lever up slowly
and gently.

11-34Maintenance and service
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires. !Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads. & Tire pressure monitoring
system (TPMS) (if equipped)
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low. The tire pressure monitor-
ing system will activate only when the
vehicle is driven. Also, this system may
not react immediately to a sudden drop in
tire pressure (for example, a blow-out
caused by running over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to
pressures higher than those shown on the tire placard. Specifically, inflate them by an
extra 1 psi (6.9 kPa, 0.07 kgf/cm2) for
every difference of 10 8F (5.6 8C) between
the temperature in the garage and the
temperature outside. By way of example,
the following table shows the required tire
pressures that correspond to various out-
side temperatures when the temperature
in the garage is 60 8F (15.6 8C).
Example:
Tire size: P225/55R17 95V, P225/60R16 97H
Standard tire pressures:
Front: 32 psi (220 kPa, 2.2 kgf/cm

.Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is
responsive. Rolling resistance is low, so
fuel consumption is also lower. .
Abnormally low tire pressure (tread
worn at shoulders)Rolling resistance is high, so fuel con-
sumption is also higher. .
Abnormally high tire pressure (tread
worn in center)Ride comfort is poor. Also, the tire
magnifies the effects of road-surface
bumps and dips, possibly resulting in
vehicle damage.
WARNING
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of
vehicle control could lead to anaccident. Maintenance and service

cified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perfor- mance.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accel-
eration, cornering, hydroplan-
ing, or peak traction charac-teristics.
& Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing thetire ’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled con-
ditions on a specified indoor labora-
tory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire failure. The grade C corresponds to a level of
performance which all passenger
car tires must meet under the
Federal Motor Vehicle Safety Stan-
dards No. 109. Grades B and A
represent higher levels of perfor-
mance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this
tire is established for a tire
that is properly inflated and
not overloaded. Excessive
speed, underinflation, or ex-
cessive loading, either sepa-
rately or in combination, can
cause heat buildup and possi-
ble tire failure. Reporting safety defects (USA)
