equipment.
.Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.
Do not use a trailer hitch other than
genuine SUBARU trailer hitch. A genuine
SUBARU hitch is available from your
SUBARU dealer.
&When you do not tow a trailer
CAUTION
.The housing should be kept dirt
and corrosion-free at the points
of contact. The surfaces only
require cleaning with a cloth.
Grease or other lubricants
should never be used.
.If the ball is not installed, the
plastic insert should then be
inserted for protection and to
prevent dirt.
When the ball is not used, place the ball
cap and store securely.
&Connecting a trailer!Trailer brakes
WARNING
.Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.
.Do not directly connect your
trailer’s hydraulic brake system
to the hydraulic brake system in
your vehicle. Direct connection
would cause the vehicle’s brake
performance to deteriorate and
could lead to an accident.
If your trailer’s total weight (trailer weight
plus its cargo weight) exceeds 1,000 lbs
(453 kg), the trailer is required to be
equipped with its own brake system.
Electric brakes or surge brakes are re-
commended, and must be installed prop-
erly. Check that your trailer’s brakes con-
form with Federal, state/province and/or
other applicable regulations. Your
SUBARU’s brake system is not designed
to be tapped into the trailer’s hydraulic
brake system. Please ask your SUBARU
dealer and professional trailer supplier for
more information about the trailer’s brake
system.!Trailer safety chains
WARNING
Always use safety chains between
your vehicle and the trailer. Towing
trailer without safety chains could
create a traffic safety hazard if the
trailer separates from the hitch due
to coupling damage or hitch ball
damage.
In case the trailer hitch connector or hitch
ball should break or become discon-
nected, the trailer could get loose and
create a traffic safety hazard.
For safety, always connect the towing
vehicle and trailer with trailer safety
chains. Two chains should be used in
total, one to the right side and the other to
the left side trailer tongue. Pass the chains
crossing each other under the trailer
tongue to prevent the trailer from dropping
onto the ground in case the trailer tongue
should disconnect from the hitch ball.
Allow sufficient slack in the chains taking
tight turn situations into account; however,
be careful not to let them drag on the
ground.

!Side mirrorsAfter 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 vehicle’s
electrical system requires modifications 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 opera-
tion of the turn signals and the brake lights
each time you connect a trailer to your
vehicle.
!Tires
WARNING
Never tow a trailer when the tempor-
ary spare tire is used. The temporary
spare tire is not designed to sustain
the towing load. Use of the tempor-
ary 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”F12-
8.
Trailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer manufacturer’s
specifications. Also check federal, state,
province and/or other applicable regula-
tions.In the event your vehicle gets a flat tire
when towing a trailer, ask a commercial
road service representative or profes-
sional 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
.For models equipped with the
BSD (Blind Spot Detection) and
RCTA (Rear Cross Traffic Alert)
driving support systems, when
towing a trailer, press the BSD/
RCTA OFF switch to deactivate
the system. The system may not
operate properly due to the
blocked radar waves. For details
about the BSD/RCTA OFF switch,
refer to“BSD/RCTA OFF switch”
F7-59.
.For models equipped with RAB
(Reverse Automatic Braking)
system, consult your SUBARU
dealer for additional information
about towing a trailer.
.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 when compared to normal
operation. For safety’s sake, you
should employ extra caution
when towing a trailer and you
should never drive at excessive
speeds. You should also keep the
following tips in mind:
.The braking power of the parking
brake may not be sufficient when
stronger braking power is
needed (e.g., when parking on a
steep slope while towing a trai-
ler).
!Before starting out on a trip
.Check the towing regulations for trailer
or caravan vehicles that vary by state/
region. Failure to comply with the proce-
dures set forth will not only compromise
your safety, but will also negate your
insurance coverage and/or may violate
the state road and traffic acts and regula-
tions.
.Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If any
problems are apparent, do not tow thetrailer.
.Check that the vehicle rests horizon-
tally with the trailer attached. If the vehicle
is tipped sharply up at the front and down
at the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution are
acceptable.
.Check that the tire rating and pressures
are correct.
.Check that the vehicle and trailer are
connected properly. Confirm that:
–the trailer tongue is connected
properly to the hitch ball.
–the trailer lights connector is con-
nected properly and trailer’sbrake
lights illuminate when the vehicle’s
brake pedal is pressed, and that the
trailer’s turn signal lights flash when
the vehicle’s turn signal lever is oper-
ated.
–the safety chains are connected
properly.
–all cargo in the trailer is secured
safely in position.
–the side mirrors provide a good
rearward field of view without a sig-
nificant blind spot.
.Sufficient time should be taken to learn
the“feel”of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping andbacking up.
!Driving with a trailer
.You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may
result in skidding or jackknifing and loss
of control.
.Avoid abrupt starts and sudden accel-
erations. If your vehicle has a manual
transmission, always start out in first gear
and release the clutch at moderate engine
revolution.
.Avoid uneven steering, sharp turns and
rapid lane changes.
.Slow down before turning. Make a
longer than normal turning radius because
the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. In a
tight turn, the trailer could hit your vehicle.
.Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ingsway.Crosswindscanbedueto
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and promptly begin
decelerating your vehicle at a gradual
pace.
.When passing other vehicles, consider-
able distance is required because of the
added weight and length caused by
attaching the trailer to your vehicle.

could strike occupants and cause
injury. Store the tire and all tools in
the proper place.&Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)The tire pressure monitoring system pro-
vides the driver with the warning message
indicated by sending a signal from a
sensor that is installed in each wheel when
tire pressure is severely low.The tire pressure monitoring system will
activate only when the vehicle is driven.
Also, this system may not react immedi-
ately to a sudden drop in tire pressure (for
example, a blow-out caused running over
a sharp object).
WARNING
.If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
(1) Keep driving straight ahead
while gradually reducing
speed.
(2) Slowly pull off the road to a
safe place. Otherwise an acci-
dent involving serious vehicle
damage and serious personal
injury could occur.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the vehicle placard
on the door pillar on the
driver’s side.
If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
