2017 SUBARU LEGACY wiring

Seat, seatbelt and SRS airbags/Front seatbelt pretensioners
pretensioners have no user-ser-
viceable parts. For required ser-
vicing of front seatbelt retractors
equipped with seatbelt preten-
sioners, consult your SUBARU
dealer.
. When discarding front seatbelt
retractor assemblies or scrap-
ping the entire vehicle due to
collision damage or for other
reasons, consult your SUBARU
dealer.
& System monitors
A diagnostic system continually monitors
the readiness of the seatbelt pretensioner
while the vehicle is being driven. The
seatbelt pretensioners share the control
modulewiththeSRSairbagsystem.
Therefore, if any malfunction occurs in a
seatbelt pretensioner, the SRS airbag
system warning light will illuminate. For
details, refer to “SRS airbag system
monitors ”F 1-68.

A rear view camera is attached to the
trunk lid (Legacy) or rear gate (Outback).
When the ignition switch is“ON ”and the
shift lever (MT models) or select lever
(CVT models) is set to “R”, the rear view
camera automatically displays the rear
view image behind the vehicle on the
audio/navigation monitor.
WARNING
. Since the rear view camera uses
a wide-angle lens, the image on
the monitor is different from the
actual view in terms of distance.
. Since the range of the image on
the monitor is limited, you should
always check the rear view and
the surrounding area with your
eyes and mirrors, and move
backward at a slow speed. Mov-
ing backward only by checking
the rear view image from the
camera could cause an accident.
. Do not disassemble or modify the
camera, switch or wiring. If
smoke comes out or you smell
a strange odor, stop using the
rear view camera immediately.
Contact your SUBARU dealer
for an inspection. Continued use
may result in accident, fire or electric shock.
CAUTION
.
If your vehicle is washed with a
high-pressure washer, do not
allow water to contact the camera
directly. Entry of water in the
camera lens may result in con-
densation, malfunction, fire or
electric shock.
. Since the camera is a precision
device, do not subject it to strong
impacts. Otherwise, malfunction,
fire or electric shock may occur.
. If mud or snow sticks to or is
frozen on the camera, you must
be very careful removing it.
Otherwise, damage done to the
camera may cause a fire or
electric shock. Pour water or
lukewarm water over the camera
to remove mud and ice, and wipe
it with a soft, dry cloth.
. Do not put a flame close to the
camera or wiring. Otherwise, da-
mage or fire may occur.
. When replacing the fuse, be sure
to use a fuse with the specified
rating. Use of a fuse with a
different rating may result in a malfunction.
. If the rear view camera is used for
a long time while the engine is
not operated, the battery may
become completely discharged.
NOTE
. Do not wipe the camera with alcohol,
benzine or paint thinner. Otherwise,
discoloration may occur. To remove
contamination, wipe the camera with a
cloth moistened with a diluted neutral
detergent and then wipe it with a soft,
dry cloth.
. When waxing the vehicle, be careful
not to apply the wax to the camera. If it
comes in contact with the camera,
moisten a clean cloth with a diluted
neutral detergent to remove the wax.
. The camera lens has hard coating to
help prevent scratches. However, when
washing the vehicle or cleaning the
camera lens, be careful not to scratch
the camera lens. Do not use a washing
brush directly on the camera lens. The
monitor screen may be adversely af-
fected.
. Strong light shined on the camera
lens may develop white light stripes
around the light source. This is not a
malfunction.

!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 and the stop
lights each time you connect a trailer to
your vehicle.
! 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. Refer to “Tires”F 12-
9 and in “GAS STATION REFERENCE ”at
the end of this manual.
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 representive or professional
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.

Maintenance and service/Maintenance precautions
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. NEVER use a circuit
tester for these wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer.
NOTE
SUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.
& Before checking or servicing
in the engine compartment
WARNING
. Always stop the engine and apply
the parking brake to prevent the
vehicle from moving.
