&Precautions against vehicle modification
WARNING
. To avoid accidental activation of
the system or rendering the sys-
tem inoperative, which may re-
sult in serious injury, no modifi-
cations should be made to any
components or wiring of the SRS
airbag system.
This includes following modifica- tions: . Installation of custom steering
wheels
. Attachment of additional trim
materials to the dashboard
. Installation of custom seats
. Replacement of seat fabric or
leather
. Installation of additional fabric
or leather on the front seat
. Attachment of a hands-free
microphone or any other ac-
cessory to a front pillar, a
center pillar, a rear pillar, the
windshield, a side window, an
assist grip, or any other cabin
surface that would be near a deploying SRS curtain airbag.
. Installation of additional elec-
trical/electronic equipment
such as a mobile two-way
radioonorneartheSRS
airbag system components
and/or wiring is not advisable.
This could interfere with prop-
er operation of the SRS airbagsystem.
CAUTION
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the SRS airbag system. . Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than genu-
ine SUBARU accessory parts.
. Modification of the suspension
system or front end structure.
. Installation of a tire of different
size and construction from the
tires specified on the vehicle
placard attached to the driver ’s
door pillar or specified for indivi-
dual vehicle models in this Own-er ’s Manual. .
Attachment of any equipment
(side steps or side sill protectors,
etc.) other than genuine SUBARU
accessory parts to the side body.
Always consult your SUBARU dealer if
you want to install any accessory parts on
your vehicle.

!Side mirrors
After hitching a trailer to your vehicle,
check that the standard side mirrors
provide a good rearward field of view
without significant blind spots. If significant
blind spots occur with the vehicle ’s stan-
dard side mirrors, use towing mirrors that
conform with Federal, state/province and/
or other applicable regulations. ! Trailer lights
CAUTION
Direct splicing or other improper
connection of trailer lights may
damage your vehicle ’s electrical
system and cause a malfunction of
your vehicle ’s lighting system. Connection of trailer lights to your vehi-cle
’s electrical system requires modifica-
tions to the vehicle ’s lighting circuit to
increase its capacity and accommodate
wiring changes. To ensure the trailer lights
are connected properly, please consult
your SUBARU dealer. Check for proper
operation of the turn signals, the brake
lights and parking lights each time you
hitch up. ! Tires
WARNING
Never tow a trailer when the tem-
porary spare tire is used. The tem-
porary spare tire is not designed 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.
Make sure that all the tires on your vehicle
are properly inflated.
The recommended cold tire pressure
under trailer towing conditions is shown
in chapter 12, “Specifications ”and in
“ GAS STATION REFERENCE ”at the
end of this manual. Adjust the rear tire
pressure to the recommended pressure
when the tires are cold. Normal pressure
should be maintained in the front tires. Trailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer manufacturer
’s
specifications.
In the event your vehicle gets a flat tire
when towing a trailer, ask a commercial
road service to repair the flat tire.
If you carry a regular size spare tire in your
vehicle or trailer as a precaution against
getting a flat tire, be sure that the spare
tire is firmly secured.
& Trailer towing tips
CAUTION
. Never exceed 45 mph (72 km/h)
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 from normal operation. Forsafety ’s sake, you should employ
extra caution when towing a
trailer and you should never
speed. You should also keep the
following tips in mind: Driving tips

11-4Maintenance and service
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. The wiring and connec-
tors of these systems are yellow
for easy identification. NEVER
use a circuit tester for thesewiring.
If your SRS airbag or seatbelt
pretensioner needs service, con-
sult your nearest SUBARU deal-
er.

11-48Maintenance and service
Fuses
CAUTION
Never replace a fuse with one hav-
ing a higher rating or with material
other than a fuse because serious
damage or a fire could result.
The fuses are designed to melt during an
overload to prevent damage to the wiring
harness and electrical equipment. The
fuses are located in two fuse boxes. One
is located under the instrument panel
behind the fuse box cover on the driver ’s
seat side.
Open the lid that is located above the
hood release knob and pull it toward you
to remove it.
The other one is housed in the engine compartment.
The spare fuses are stored in the main
fuse box cover in the engine compart-ment.
The fuse puller is stored in the main fuse
box in the engine compartment.

1) Good
2) Blown
If any lights, accessories or other electrical
controls do not operate, inspect the
corresponding fuse. If a fuse has blown,
replace it.
1. Turn the ignition switch to the “LOCK ”
position and turn off all electrical acces- sories.
2. Remove the cover.
3. Determine which fuse may be blown.
The back side of each fuse box cover andthe “Fuses and circuits ”section in chapter
12 in this manual show the circuit for eachfuse.4. Pull out the fuse with the fuse puller.
5. Inspect the fuse. If it has blown,
replace it with a spare fuse of the samerating.
6. If the same fuse blows again, this
indicates that its system has a problem.
Contact your SUBARU dealer for repairs. Main fuse
Main fuse box
The main fuses are designed to melt
during an overload to prevent damage to
the wiring harness and electrical equip-
ment. Check the main fuses if any
electrical component fails to operate (ex-
cept the starter motor) and other fuses are
good. A melted main fuse must be
replaced. Use only replacements with the
same specified rating as the melted main
fuse. If a main fuse blows after it is
replaced, have the electrical system
checked by your nearest SUBARU dealer. Maintenance and service
