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
module with the airbag system. 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-
62.
& System servicing
WARNING
. When discarding a seatbelt re-
tractor assembly or scrapping
the entire vehicle damaged by a
collision, consult your SUBARU

. Tampering with or disconnecting
the system ’s wiring could result
in accidental activation of the
seatbelt pretensioner and/or air-
bag or could make the system inoperative, which may result in
serious injury. Do not use elec-
trical test equipment on any
circuit related to the seatbelt
pretensioner and airbag sys-
tems. For required servicing of
the seatbelt pretensioner, consult
your nearest SUBARU dealer.

Rear view camera (if equipped)
Legacy
OutbackA 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 (AT
or CVT models) is set to “R ”, the rear view
camera automatically displays the rear
view image behind the vehicle on the
audio/navigation monitor or on the inside
mirror depending on the model.
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 Interior equipment

!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 brake
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. 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 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:
! Before starting out on a trip
. Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer. . Check that the vehicle sits horizontally
with the trailer attached. If the vehicle is
tipped sharply up at the front and down at Driving tips
