Driving tips/Trailer towing (Legacy)
Trailer towing (Legacy)
Your vehicle is neither designed nor
intended to be used for trailer towing.
Therefore, never tow a trailer with your
vehicle.
SUBARU assumes no responsibility for
injuries or vehicle damage that may result
from trailer towing, from any trailer towing
equipment or from any errors or omissions
in the instructions accompanying such
equipment. SUBARU warranties do not
apply to vehicle damage or malfunction
caused by trailer towing.
Trailer towing (Outback)
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 and air
conditioning system cooling performance.
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. Do not use towing equipment
other than genuine SUBARU towing
equipment. In addition, be sure to follow
the instructions on correct installation and
use provided by SUBARU.
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.
Regularly check that the hitch mounting
bolts and nuts are tightened securely.
& 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 “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 (en-
gine, 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)
8-22

!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).
NOTE
For vehicles with trailer brakes, the
trailer tongue load exceeds 200 lbs (90
kg) when calculated at 8% of the
maximum total trailer weight.
Even in this case, the maximum value
is 200 lbs (90 kg).
1) Jack
2) Bathroom scale
The tongue load can be weighed with a
bathroom scale as shown in the following
illustration. When weighing the tongue
load, be sure to position the towing
coupler at the height at which it would be
during actual towing, using a jack as
shown.
F: Front
The tongue load can be adjusted by
proper distribution of the load in the trailer.
Never load the trailer with more weight in
the back than in the front; approximately
60 percent of the trailer load should be in
the front and approximately 40 percent in
the rear. Also, distribute the load as evenly
as possible on both the left and right
sides.
Be sure that all cargo is firmly secured to
prevent a change in weight distribution
while driving.

Appearance care/Corrosion protection
washing device.
.Clean the vehicle (including the alumi-
num wheels) with water as soon as
possible when it has been splashed with
sea water, exposed to sea breezes, or
driven on roads treated with salt or other
agents.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 reliable
operation.
& Most common causes of
corrosion
The most common causes of corrosion
are:
. The accumulation of moisture retaining
dirt and debris in body panel sections,
cavities, and other areas.
. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor accidents.
Corrosion is accelerated on the vehicle
when:
. 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.
. It is driven in areas of high humidity,
especially when temperatures range just
above freezing.
. Dampness in certain parts of the vehicle remains for a long time, even
though other parts of the vehicle may be
dry.
.
High temperatures will cause corrosion
to parts of the vehicle which cannot dry
quickly due to lack of proper ventilation.
& 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

Maintenance and service/Replacement of brake pad
&Checking the clutch pedal
free play
1) 0.19 –0.44 in (5 –11 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
CAUTION
. If you continue to drive despite
the scraping noise from the audi-
ble brake pad wear indicator, it
will result in the need for costly
brake rotor repair or replace-
ment.
. It is recommended that you dis-
connect the vehicle battery be-
fore replacing the brake pad.
However, it is dangerous to dis-
connect the vehicle battery. We
recommend that you have your
SUBARU dealer replace the
brake pad.
The disc brakes 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
When replacing the brake pad, use only
genuine SUBARU parts. After replace-
ment, the new parts must be broken in as
follows:
! Brake pad
While maintaining a speed of 30 to 40
mph (50 to 65 km/h), step on the brake
pedal lightly. Repeat this five or more
times. Also, apply and release the electro-
nic parking brake five or more times.
11-24

Tires and wheels
&Types of tires
You should be familiar with type of tires
present on your vehicle.
! All season tires
The factory-installed tires on your new
vehicle are all season tires.
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads.
All season tires are identified by “ALL
SEASON ”and/or “M+S”(Mud & Snow) on
the tire sidewall.
! Summer tires
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered
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/cm
2) 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: 225/55R17 97V, 225/50R18 95H
Standard tire pressures:
Front: 33 psi (230 kPa, 2.3 kgf/cm
2)
Rear: 32 psi (220 kPa, 2.2 kgf/cm2)
Garage temperature: 60 8F (15.6 8C)

Maintenance and service/Tires and wheels
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally.
.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 an
accident.
