2008 SUBARU OUTBACK ECU

NOTE
For vehicles with trailer brakes, the
trailer tongue load exceeds 200 lbs (90
kg) when calculated at 8% of the
maximum total trailer weight.
Even in this case, the maximum value
is 200 lbs (90 kg).
1) Jack
2) Bathroom scale
The tongue load can be weighed with a
bathroom scale as shown in the following
illustration. When weighing the tongue
load, be sure to position the towing
coupler at the height at which it would be
during actual towing, using a jack asshown.
F: Front
The tongue load can be adjusted by
proper distribution of the load in the trailer.
Never load the trailer with more weight in
the back than in the front; approximately
60 percent of the trailer load should be in
the front and approximately 40 percent in
the rear. Also, distribute the load as evenly
as possible on both the left and rightsides.
Be sure that all cargo is firmly secured to
prevent a change in weight distribution
while driving. &
Trailer hitches
WARNING
Never drill the frame or under-body
of your vehicle to install a commer-
cial trailer hitch. If you do, danger-
ous exhaust gas, water or mud may
enter the passenger compartment
through the drilled hole. Exhaust
gas contains carbon monoxide, a
colorless and odorless gas which is
dangerous, or even lethal, if inhaled.
Also, drilling the frame or under-
body of your vehicle could cause
deterioration of strength of your
vehicle and cause corrosion around
the drilled hole.
CAUTION
. Do not modify the vehicle ex-
haust system, brake system, or
other systems when installing a
hitch or other trailer towingequipment.
. Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.

!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

8-28Driving tips
! 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 ’s brake
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- 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.

Flat tires
If you have a flat tire while driving, never
brake suddenly; keep driving straight
ahead while gradually reducing speed.
Then slowly pull off the road to a safeplace. &Changing a flat tire
WARNING
. Do not jack up the vehicle on an
incline or a loose road surface.
The jack can come out of the
jacking point or sink into the
ground and this can result in a
severe accident.
. Use only the jack provided with
your vehicle. The jack supplied
with the vehicle is designed only
for changing a tire. Never get
under the vehicle while support-
ing the vehicle with this jack. .
Always turn off the engine before
raising the flat tire off the ground
using the jack. Never swing or
push the vehicle supported with
the jack. The jack can come out
of the jacking point due to a jolt
and this can result in a severeaccident.
1. Park on a hard, level surface, when-
ever possible, then stop the engine.
2. Set the parking brake securely and
shift a manual transmission vehicle in
reverse or an automatic transmission
vehicle in the “P ”(Park) position.
3. Turn on the hazard warning flasher
and have everyone get out of the vehicle.
4. Put wheel blocks at the front and rear
of the tire diagonally opposite the flat tire.

10. Remove the wheel nuts and the flat tire.
11. Before putting the spare tire on, clean
the mounting surface of the wheel and hub
with a cloth.
12. Put on the spare tire. Replace the wheel nuts. Tighten them by hand.
WARNING
Do not use oil or grease on the
wheel studs or nuts when the spare
tire is installed. This could cause the
nuts to become loose and lead to anaccident.
13. Turn the jack handle counterclockwise
to lower the vehicle.
14. Use the wheel nut wrench to securely
tighten the wheel nuts to the specified
torque, following the tightening order in the illustration.
The torque for tightening the nuts is 74 to
89 lbf·ft (100 to 120 N·m, 10 to 12 kgf·m).
This torque is equivalent to applying approximately 88 to 110 lbs (40 to 50 kg)
at the top of the wheel nut wrench. Never
use your foot on the wheel nut wrench or a
pipe extension on the wrench because
you may exceed the specified torque.
Have the wheel nut torque checked at
the nearest automotive service facility.
15. Store the flat tire in the spare tire compartment.
Put the spacer and tighten the attaching
bolt firmly.
Also store the jack and jack handle in their
storage locations.

CAUTION
Never use the rear towing hook to
tie the vehicle down.
Front tie-down hooks:
The front tie-down hooks are located
between each of the front tires and the
front bumper.
Rear tie-down hooks:
The rear tie-down hooks are located near
each of the jack-up reinforcements.

WARNING
Use the rear tie-down hooks only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip off
the hooks, possibly causing a dan-
gerous situation.
& Using a flat-bed truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the selector lever into the “P ”
position for automatic transmission vehi-
cles or “1st ”for manual transmission
vehicles.
2. Pull up the parking brake lever firmly. 3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out. &
Towing with all wheels on the ground
WARNING
. Never turn the ignition switch to
the “LOCK ”position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked.
. Remember that the brake booster
and power steering do not func-
tion when the engine is not running. Because the engine is
turned off, it will take greater
effort to operate the brake pedal
and steering wheel.
CAUTION
. If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
. Do not run the engine while being
towed using this method. Trans-
mission damage could result if
the vehicle is towed with the
engine running.
. For vehicles with automatic
transmission, the traveling speed
must be limited to less than 20
mph (30 km/h) and the traveling
distance to less than 31 miles (50
km). For greater speeds and
distances, transport your vehicle
on a flat-bed truck.
1. Check the transmission and differen-
tial oil levels and add oil to bring it to the
upper level if necessary.
2. Release the parking brake and put the
transmission in neutral.
3. The ignition switch should be in the “ Acc ”position while the vehicle is being In case of emergency
