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.

To help prevent corrosion
Wash the vehicle regularly to prevent corrosion of the
body and suspension components. Also, wash the ve-
hicle promptly after driving on any of the following sur- faces: y roads that have been salted to prevent them from
freezing in winter y mud, sand, or gravel
y coastal roads
After the winter has ended, it is recommended 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, steer-
ing system, floor pan, and fenders. If any of them are
found to be rusted, they should be given an appropri-
ate 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 ac- cumulation 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, cor-
rosion 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 damp-ness.
If your vehicle is operated in cold weather and/or in ar-
eas 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 period-
ically.

2Maintenance and serviceMaintenance schedule
The scheduled maintenance items required to be ser-
viced at regular intervals are shown in the “Warranty
and Maintenance Booklet”.
For details of your maintenance schedule, read the
separate “Warranty and Maintenance Booklet”.Maintenance precautions
When maintenance and service are required, it is rec-
ommended that all work be done by an authorized
SUBARU dealer.
If you perform maintenance and service by yourself,
you should familiarize yourself with the information
provided in this section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could cause improper
or unsafe vehicle operation. Any problems caused by
improper maintenance and service performed by you
are not eligible for warranty coverage.
yTesting of an All-Wheel Drive vehicle must
NEVER be performed on a single two-wheel dy-
namometer or similar apparatus. Attempting to
do so will result in transmission damage and in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby.y Always select a safe area when performing
maintenance on your vehicle.y Always be very careful to avoid injury when
working on the vehicle. Remember that some of

2Maintenance and service
the materials in the vehicle may be hazardous if
improperly used or handled, for example, bat-tery acid. y
Your vehicle should only be serviced by per-
sons fully competent to do so. Serious person-
al injury may result to persons not experienced
in servicing vehicles. y Always use the proper tools and make certain
that they are well maintained. y Never get under the vehicle supported only
by a jack. Always use a safety stands to sup-
port the vehicle. y Never keep the engine running in a poorly
ventilated area, such as a garage or other
closed areas. y Do not smoke or allow open flames around
the fuel or battery. This will cause a fire. y Because the fuel system is under pressure,
replacement of the fuel filter should be per-
formed only by your SUBARU dealer.y Wear adequate eye protection to guard
against getting oil or fluids in your eyes. If
something does get in your eyes, thoroughly
wash them out with clean water. y Do not tamper with the wiring of the SRS air-
bag system or seatbelt pretensioner system, or
attempt to take its connectors apart, as that may activate the system or it can render it inop-
erative. The wiring and connectors of these
systems are yellow for easy identification. NEV-
ER use a circuit tester for these wiring.
If your SRS airbag or seatbelt pretensioner
needs service, consult your nearest SUBARU
dealer.
„ Before checking or servicing in the en-
gine compartment
yAlways stop the engine and set the parking
brake firmly to prevent the vehicle from mov-
ing. y Always let the engine cool down. Engine
parts become very hot when the engine is run-
ning and remain hot for some time after the en-
gine is stopped.y Do not spill engine oil, engine coolant, brake
fluid or any other fluid on hot engine compo-
nents. This may cause a fire.y Always remove the key from the ignition
switch. When the ignition switch is in the “ON”
position, the cooling fan may operate suddenly

even when the engine is stopped.
„ When you do checking or servicing in
the engine compartment while the en-
gine is running
A running engine can be dangerous. Keep your
fingers, hands, clothing, hair and tools away
from the cooling fan, belts and any other mov-
ing engine parts. Removing rings, watches and
ties is advisable.
Engine hood
To open the hood:
1. If the wiper blades are lifted off the windshield, re-
turn them to their original positions.
2. Pull the hood release knob under the instrument
panel.
