8-22Driving tips
&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
recommended, and must be installed
properly. Check that your trailer ’s brakes
conform with Federal, state/province and/
or other applicable regulations. YourSUBARU ’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 a
trailer without safety chains could
create a traffic safety hazard if the
trailer separates from the hitch due
to coupling damage or hitch balldamage.
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. 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 discon-
nect from the hitch ball. Allow sufficient
slack in the chains taking tight-turn situa-
tions into account; however, be careful not
to let them drag on the ground.
For more information about the safety
chain connection, refer to the instructions
for your hitch and trailer. !
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 brake lights and turn
signal 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 shownin “Tires ”F 12-5 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
WARNING
. 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
extracautionwhentowinga
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
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 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
safety in position.– the side mirrors provide a good
rearward field of view without a sig- Driving tips

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 and
backing 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 ofcontrol. . 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 enginerevolution. . 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 yourvehicle. . Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and slow down immediately but gradually. .
When passing other vehicles, consid-
erable distance is required because of the
added weight and length caused by
attaching the trailer to your vehicle.
1) Left turn
2) Right turn
. Backing up with a trailer is difficult and
takes practice. When backing up with a
trailer, never accelerate or steer rapidly.
When turning back, grip the bottom of the
steering wheel with one hand and turn it to
the left for a left turn, and turn it to the right
for a right turn. . If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed
immediately by the nearest SUBARU
dealer. !
Driving on grades
. Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle ’s brakes. Do not
make sudden downshifts. . When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. . When driving uphill in hot weather, pay
attention to the coolant temperature high
warning light (for all models) and AT OIL
TEMP warning light (for AT models)
because the engine and transmission are
relatively prone to overheating under
these conditions. If the coolant tempera-
ture high warning light or the AT OIL TEMP
warning light illuminates, immediately turn
off the air conditioner and stop the vehicle
in the nearest safe location. For further
instructions and additional information,
refer to the following sections.
–“If you park your vehicle in case of
an emergency ”F 9-2
–“ Engine overheating ”F 9-12
–“ Coolant temperature low indicator
light/Coolant temperature high warn-
ing light ”F 3-13
–“ AT OIL TEMP warning light (AT
models) ”F 3-14
. If your vehicle has an automatic trans-

mission, avoid using the accelerator pedal
to stay stationary on an uphill slope
instead of using the parking brake or foot
brake. That may cause the transmission
fluid to overheat. .If your vehicle has an automatic trans-
mission, place the select lever as follows.
Uphill slopes: “D ”position
Downhill slopes: A low-speed gear posi-
tion to use engine braking ! Parking on a grade
Always block the wheels under both
vehicle and trailer when parking. Apply
the parking brake firmly. You should not
park on a hill or slope. But if parking on a
hill or slope cannot be avoided, you
should take the following steps.
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks
under both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then
apply the parking brake; slowly release
the regular brakes.
5. Shift into 1st or reverse gear (manual
transmission models) or the “P ” position
(automatic transmission models) and shut
off the engine. Driving tips
