required due to the additional load. (Refer
to “Maintenance schedule under severe
driving conditions” in the “Warranty and
Maintenance Booklet”.)
Under no circumstances should a trailer
be towed with a new vehicle or a vehicle
with any new powertrain component (en-
gine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles
(1,600 km) of driving. „
Maximum load limits
TTotal trailer weight
Total trailer weight
The total trailer weight (trailer weight plus
its cargo load) must never exceed the
maximum weight indicated in the following table.
Never exceed the maximum load
limits explained in the following. Ex-
ceeding the maximum load limits
could cause personal injury and/or
vehicle damage. y Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.
yBefore towing a trailer, check the
trailer total weight, GVW, GAWs
and tongue load. Make sure the
load and its distribution in your
vehicle and trailer are acceptable.

Towing
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following pro-
cedures for safety. „
Towing and tie-down hooks
The towing hooks should be used only in
an emergency (e.g., to free a stuck vehicle
from mud, sand or snow).
Front towing hook (OUTBACK models):
1. Take out the towing hook, screwdriver
and wheel nut wrench from the on board
tool bucket. 2. Wrap a flat-head screwdriver in a vinyl
tape or cloth, insert it into the gap between
the cover and the front bumper, and use it
to lever the cover open.
3. Pull the entire front fog light cover to-
ward you.
Never tow AWD vehicles (both AT
and MT) with the front wheels raised
off the ground while the rear wheels
are on the ground, or with the rear
wheels raised off the ground while
the front wheels are on the ground.
This will cause the vehicle to spin
away due to the operation or deteri-
oration of the center differential.
900030
y
Use only the specified towing
hooks and tie-down hooks. Never
use suspension parts or other
parts of the body for towing or tie-
down purposes.
y Never use the tie-down hook clos-
est to the muffler under the vehi-
cle for towing purposes.
y To prevent deformation to the
bumper and the towing hook, do
not apply excessive lateral load to
the towing hooks.

each of the jack-up reinforcements.
„Using a flat-bed truck
This is the best way to transport your vehi-
cle. Use the following procedures to en-
sure safe transportation.
1. Shift the selector lever into the “P” po-
sition for automatic transmission vehicles
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
1. Check the transmission and differential
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.
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.
900033
yNever turn the ignition switch to
the “LOCK” position while the ve-
hicle is being towed because the
steering wheel and the direction
of the wheels will be locked.
900254
yRemember that the brake booster
and power steering do not func-
tion when the engine is not run-
ning. Because the engine is
turned off, it will take greater ef-
fort to operate the brake pedal and
steering wheel.
y If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
y Do not run the engine while being
towed using this method. Trans-
mission damage could result if
the vehicle is towed with the en-
gine running.
y For vehicles with automatic trans-
mission, 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.

„Recommended fluid
Use one of the following types of automat-
ic transmission fluid.

sion Fluid Type-HP
IDEMITSU ATF HP
Castrol Transmax J
Pennzoil ATF-J*
* Available only in the USA (except
Alaska and Hawaii)
NOTE
Using any non-specified type of auto-
matic transmission fluid could result in
damage inside the transmission. When
replacing the automatic transmission
fluid, be sure to use the kind specified
above. Front differential gear oil (AT
vehicles) „
Checking the oil level
1) Yellow handle
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again. 1) Upper level
2) Lower level
3. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.Be careful not to spill automatic
transmission fluid when adding it. If
automatic transmission fluid touch-
es the exhaust pipe, it may cause a
bad smell, smoke, and/or a fire. If au- tomatic transmissi on fluid gets on
the exhaust pipe, be sure to wipe it
off.
