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 cor-
rect.
Check that the vehicle and trailer are
connected properly. Confirm that – the trailer tongue is connected prop-
erly to the hitch ball. – the trailer lights connector is connect-
ed properly and trailer ’s brake lights illu-
minate when the vehicle ’s brake pedal
is pressed, and that the trailer ’s turn sig-
nal lights flash when the vehicle ’s turn
signal lever is operated.– the safety chains are connected prop-
erly.– all cargo in the trailer is secured safe-
ty in position.– the side mirrors provide a good rear-
ward field of view without a significant
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 re-
sult in skidding or jackknifing and loss of
control.
Avoid abrupt starts and sudden acceler-
ations. If your vehicle has a manual trans-
mission, always start out in first gear and
release the clutch at moderate engine rev-
olution.
Avoid uneven steering, sharp turns and
rapid lane changes.
Slow down before turning. Make a long-
er than normal turning radius because the
trailer wheels will be closer than the vehi-
cle 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-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
tracks or buses. If swaying occurs, firmly
grip the steering wheel and slow down im-
mediately but gradually.
When passing other vehicles, consider-
able distance is required because of the
added weight and length caused by at-
taching 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 im-
mediately 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-

9-4 In case of emergency
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 safe
place.
Changing a flat tire1. Park on a hard, level surface, whenev-
er possible, then stop the engine.
2. Set the parking brake securely and
shift a manual transmission vehicle in re-
verse or an automatic transmission vehi-
cle 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.
Sedan
1) Jack
2) Jack handle
3) Spare tireDo not jack up the vehicle on an
incline or a loose road surface.
The jack can come out of the jack-
ing point or sink into the ground
and this can result in a severe ac-
cident.
Use only the jack provided with
your vehicle. The jack supplied
with the vehicle is designed only
for changing a tire. Never get un-
der the vehicle while supporting
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 severe acci-
dent.

13.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 58 to
72 lbf ∑ft (80 to 100 N ∑m, 8 to 10 kgf ∑m).
This torque is equivalent to applying ap-
proximately 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. 14.Store the flat tire in the spare tire com-
partment.
Put the spacer and tighten the attaching
bolt firmly.
Also store the jack and wheel nut wrench
in their storage locations.After placing the jack in its storage loca-
tion, turn the jackscrew clockwise by hand
until it becomes too hard to turn. Then,
tighten it by an additional 1/4
– 1/3 of a
turn using a screwdriver or the jack han-
dle. Unless the jack is properly secured, it
may rattle while the vehicle is moving.

Never place a tire or tire changing
tools in the passenger compartment
after changing wheels. In a sudden
stop or collisions, loose equipment
could strike occupants and cause
injury. Store the tire and all tools in
the proper place.

9-12 In case of emergency
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:
1. Take the towing hook and screwdriver
out of the tool bag. Take the jack handle
out of the trunk (Sedan) or cargo area
(Wagon).
2. Pry off the cover on the front bumper
using a screwdriver, and you will find a
threaded hole for attaching the towing
hook. 3. Screw the towing hook into the thread
hole until its thread can no longer be seen.
4. Tighten the towing hook securely using
the jack handle.
After towing, remove the towing hook fromthe vehicle and stow it in the tool bag.
Fit the fog light cover on the bumper.
Rear towing hook:

900273
Do not use the towing hook ex-
cept when towing your vehicle.
Be sure to remove the towing
hook after towing. Leaving the
towing hook mounted on the vehi-
cle could interfere with proper op-
eration of the SRS airbag system
in a frontal collision.

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.
3. The ignition switch should be in the“ ACC ” position while the vehicle is being
towed.
4. Take up slack in the towline slowly to
prevent damage to the vehicle.
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), be careful not to scrape
them when placing the vehicle on
the carrier and when removing the
vehicle from the carrier.
900065
Never 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.
Remember 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.
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 en-
gine running.
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.

3. Release the secondary hood release
located under the front grille by moving
the lever toward the left.
Lift up the hood, release the hood prop
from its retainer and put the end of the hood prop into the slot in the hood.
To close the hood:
1. Lift the hood slightly and remove the
hood prop from the slot in the hood and re-
turn the prop to its retainer.
2. Lower the hood until it approaches ap-
proximately
12 in (30 cm) from the closed
position and let it drop.
After closing the hood, be sure the hood is
securely locked.
If this does not close the hood, release it
from a slightly higher position. Do not
push the hood forcibly to close it. It could
deform the metal.
B00447
B00448
Always check that the hood is prop-
erly locked before you start driving.
If it is not, it might fly open while the
vehicle is moving and block your
view, which may cause an accident
and serious bodily injury.

3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.
Changing the coolant
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant is
replaced.
Change the engine coolant and add gen-
uine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule.
1. Remove the under cover.
2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely.
NOTE (Turbo model only)
The cap (without tabs) on top of the ra-
diator does not need to be removed. To add coolant, remove the cap (with tabs)
on the coolant tank on top of the en-
gine.
4. Install the under cover.
Non-turbo models
1) Filler neck
2) Fill up to this level
Be careful not to spill engine cool-
ant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on the
exhaust pipe, be sure to wipe it
off.
Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
B00018
B00019
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.

B00067
Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and light-
ers. Never expose a battery to an
open flame or electric sparks. Bat-
teries give off a gas which is high-
ly flammable and explosive.
For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery.
Do not let battery fluid contact
eyes, skin, fabrics, or paint be-
cause battery fluid is a corrosive
acid. If battery fluid gets on your
skin or in your eyes, immediately
flush the area with water thor-
oughly. Seek medical help imme-
diately if acid has entered the
eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water, and
seek medical attention immediate-
ly.
