brake fluid SUBARU OUTBACK 2006 Owners Manual

Instruments and controls
3-21
– CONTINUED –This light has the following three func-
tions:
T Parking brake warning
The light comes on with the parking brake
applied while the ignition switch is in the
“ON” position. It goes out when the park-
ing brake is fully released.
T Brake fluid level warning
This light comes on when the brake fluid
level has dropped to near the “MIN” level
of the brake fluid reservoir with the ignition
switch in the “ON” position and with the
parking brake fully released.
If the brake system warning light should
come on while driving (with the parking
brake fully released and with the ignition
switch positioned in “ON”), it could be an
indication of leaking of brake fluid or worn
brake pads. If this occurs, immediately
stop the vehicle at the nearest safe place
and check the brake fluid level. If the fluid
level is below the “MIN” mark in the reser-
voir, do not drive the vehicle. Have the ve-
hicle towed to the nearest SUBARU deal- er for repair.
T Electronic Brake Force Distribution
(EBD) system warning
The brake system warnin g light also illu-
minates if a malfunction occurs in the EBD
system. In that event, it comes on together
with the ABS warning light.
The EBD system may be faulty if the brake
system warning light and ABS warning
light illuminate simultaneously during driv-
ing.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are ap-
plied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe, flat
place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both
warning lights go ou t, the EBD system
may be faulty.
Drive carefully to the nearest SUBARU
dealer and have t he system inspected.
4. If both warning lights come on again
and stay illuminated after the engine has been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the
“MIN” mark, the EBD system may be
faulty. Drive carefully to the nearest
SUBARU dealer and have the system in-
spected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est SUBARU dealer for repair.
„ Low fuel warning light The low fuel warning light comes on when
the tank is nearly em pty approximately 2.6
US gal (10.0 liters, or 2.2 Imp gal). It only
operates when the ignition switch is in the
“ON” position.
NOTE This light does not go out unless the
tank is replenished up to an internal
fuel quantity of approximately 3.7 US
gal (14 liters, 3.1 Imp gal).y If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.

Starting and operating
7-7Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
The EPA has issued regulations for in-
specting the On-Board Diagnostic (OBD)
system as part of the state emissions in-
spection. The OBD system is designed to
detect engine and transmission problems
that might cause vehicle emissions to ex-
ceed allowable limits. These inspections
apply to all 1996 model year and newer
passenger cars and li ght trucks. Over 30
states plus the Distr ict of Columbia have
implemented the OBD system inspection.
y The inspection of the OBD system con-
sists of a visual operational check of the
“ CHECK ENGINE ” warning light/malfunc-
tion indicator lamp (MIL) and an examina-
tion of the OBD system with an electronic
scan tool while the engine is running.
y A vehicle passes
the OBD system in-
spection if proper the “ CHECK ENGINE ”
warning light/MIL illumination is observed,
there is no stored diagnostic trouble
codes, and the OBD system readiness
monitors are complete.
y A vehicle fails
the OBD inspection if the
“ CHECK ENGINE ” warning light/MIL is
not properly operating or there is one or
more diagnostic trouble codes stored in vehicle’s computer with the “ CHECK EN-
GINE ” warning light/MIL illuminated.
y A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBD system readiness monitors “ Not
Ready ” is greater than one. Under this
condition, the vehicle operator should be
instructed to drive his/her vehicle for a few
days to set the monitors and return for an
emission re-inspection.
y Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service. Preparing to drive You should perform the following checks
and adjustments every day before you
start driving.
1. Check that all windows, mirrors, and
lights are clean and unobstructed.
2. Check the appearance and condition of
the tires. Also check tires for proper infla-
tion.
3. Look under the vehicle for any sign of
leaks.
4. Check that the hood, trunk (Sedan)
and rear gate (Station wagon) are fully
closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside and
outside mirrors.
7. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
8. Check the operation of the warning and
indicator lights when the ignition switch is
turned to the “ON” position.
9. Check the gauges, indicator and warn-
ing lights after starting the engine.
NOTE Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.

Starting and operating

– CONTINUED –Never exceed posted speed limits.
„ Driving tipsDo not drive with your foot resting on the
clutch pedal and do not use the clutch to
hold your vehicle at a standstill on an up-
grade. Either of those actions may cause
clutch damage.
Do not drive with your hand resting on the
shift lever. This may cause wear on the
transmission components.
When it is necessary to reduce vehicle
speed due to slow traffic, turning corners,
or driving up steep hills, downshift to a
lower gear before the engine starts to la-
bor.
y On steep downgrades, downshift the
transmission to 4th, 3rd or 2nd gear as
necessary; this helps to maintain a safe
speed and to extend brake pad life.
In this way, the engine provides a braking
effect. Remember, if you “ride” (over use)
the brakes while descending a hill, they
may overheat and not work properly.
y The engine may, on rare occasions,
knock when the vehicle rapidly acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate a
fault.
y A slight reduction in output torque may occur in the models with a 2.5-liter turbo
engine before the engine warms up.
Automatic transmission – 4-
speed The automatic transmission is electroni-
cally controlled and provides 4 forward
speeds and 1 reverse speed. Also, it has
a manual mode and a SPORT mode.
Do not shift from the “P” or “N” po-
sition into the “D ” or “R” position
while depressing the accelerator
pedal. This may cause the vehicle to
jump forward or backward.
y Shift into the “P” or “R” position
only after the vehic le is complete-
ly stopped. Shifting while the ve-
hicle is moving may cause dam-
age to the transmission.
y Do not race the engine for more
than five seconds in any position
except the “N” or “P” position
when the brake is set or when
chocks are used in the wheels.
This may cause the automatic
transmission fluid to overheat.

7-12 Starting and operating
NOTE y When the engine coolant tempera-
ture is still low, your vehicle’s automat-
ic transmission will up-shift at higher
engine speeds than when the coolant
temperature is sufficiently high in or-
der to shorten the warm-up time and
improve driveability. The gearshift tim-
ing will automatically shift to the nor-
mal timing after the engine has warmed
up.
y Immediately after ATF (automatic
transmission fluid) is replaced, you
may feel that the automatic transmis-
sion operation is somewhat unusual.
This results from invalidation of data
which the on-board computer has col-
lected and stored in memory to allow the transmission to shift at the most
appropriate times for the current con-
dition of your vehicle. Optimized shift-
ing will be restored as the vehicle con-
tinues to be driven for a while.
„ Selector lever
: Shift possible with brake pedal de-
pressed
: Shift possible with brake pedal not
depressed
The selector lever has four positions, “P”,
“R”, “N”, “D” and also has manual gate for
using “SPORT” mode or manual mode.
T P (Park)
This position is for parking the vehicle and
starting the engine. In this position, the transmission is me-
chanically locked to prevent the vehicle
from rolling freely.
When you park the vehicle, first set the
parking brake fully, then shift into the “P”
position. Do not hold the vehicle with only
the transmission.
To shift the selector lever from the “P” to
any other position, you should depress the
brake pedal fully then move the selector
lever. This prevents the vehicle from
lurching when it is started.
T R (Reverse)
This position is for backing the vehicle.
To shift from the “N” to “R” position, stop
the vehicle completely then move the le-
ver to the “R” position.
T N (Neutral)
This position is for restarting a stalled en-
gine.
In this position the wheels and transmis-
sion are not locked. In this position, the
transmission is neutral; the vehicle will roll
freely, even on the slightest incline unless
the parking brake or foot brake is on.
Avoid coasting with the transmission neu-
tral.
During coasting, there is no engine brak-
ing effect.y Avoid shifting from one of the for-
ward driving positions into the
“R” position or vice versa until the
vehicle has completely stopped.
Such shifting may cause damage
to the transmission.
y When parking the vehicle, first se-
curely apply the parking brake
and then place the selector lever
in the “P” position. Avoid parking
for a long time with the selector le-
ver in any other position as doing
so could result in a dead battery. 700107

2. Take out the screwdriver from the tool
bucket.
3. Remove the cover by prying on the
edge with a flat-head screwdriver. 4. Insert the key into the hole.
5. Push down on the screwdriver and
move the selector leve r from the “P” to the
“N” position.
6. Remove the screwdriver from the hole.
Depress the brake pedal and start the en-
gine.

NOTE (3.0-liter models only) To protect the engine while the “P” po-
sition is selected, the engine is con-
trolled such that the engine speed
does not become too high even if the
accelerator pedal is pressed hard.

– CONTINUED –Power steering
The power steering system operates only
when the engine is running.
If you lose power stee ring assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
NOTE Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power st eering pump which
is located at the right-front area of the
engine compartment. This noise is nor-
mal. It does not indicate power steering
system trouble. Braking „ Braking tips
T When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a re-
sult, brake stopping distance will be long-
er. To dry the brakes, drive the vehicle at
a safe speed while lightly depressing the
brake pedal to heat up the brakes.
T Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking.
T Braking when a tire is punctured
Do not depress the brake pedal suddenly when a tire is punctured. This could cause
a loss of control of the vehicle. Keep driv-
ing straight ahead while gradually reduc-
ing speed. Then slowly pull off the road to
a safe place.
„ Brake system T Two separate circuits
Your vehicle has a dual circuit brake sys-
tem. Each circuit works diagonally across
the vehicle. If one circuit of the brake sys-
tem should fail, the other half of the sys-
tem still works. If one circuit fails, the
brake pedal will go down much closer to
the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
T Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. Do not
turn off the engine while driving because
that will turn off the brake booster, result-
ing in poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to push the pedal much harder
than normal and the braking distance will
increase.Do not hold the steering wheel at the
fully locked position left or right for
more than five seconds. This may
damage the power steering pump. Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.

7-28 Starting and operating
Electronic Br ake Force Dis-
tribution (EBD) system The EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of brak ing force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS system and uses some of the ABS
system’s components to perform its func-
tion of optimizing the distribution of brak-
ing force. If any of the ABS components
used by the EBD function fails, the EBD
system also stops working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction. „ Steps to take if EBD system
fails
If a malfunction occu rs in the EBD system,
the system stops working and the brake
system warning light and ABS warning
light come on simultaneously.
The EBD system may be faulty if the brake
system warning light and ABS warning
light illuminate simultaneously during driv-
ing.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are ap-
plied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.
If the brake system warning light and ABS warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe, flat
place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both
warning lights go out, the EBD system
may be faulty.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
4. If both warning lights come on again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the
“MIN” mark, the EBD system may be
faulty. Drive carefully to the nearest
SUBARU dealer and have the system in-
spected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est SUBARU dealer for repair. 700349

Driving tips
8-7
– CONTINUED –ground from under your tires, resulting in
possible loss of traction and even vehicle
rollover.
y Always check your brakes for effective-
ness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads.
y Do not drive or park over or near flam-
mable materials such as dry grass or fall-
en leaves, as they may burn easily. The
exhaust system is very hot while the en-
gine is running and right after engine
stops. This could create a fire hazard.
y After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from
the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur.
y Secure all cargo carried inside the vehi-
cle and make certain that it is not piled
higher than the seatbacks. During sudden
stops or jolts, unsecured cargo could be
thrown around in the vehicle and cause in-
jury. Do not pile heavy loads on the roof.
Those loads raise the vehicle’s center of
gravity and make it more prone to tip over. y If you must rock the vehicle to free it
from sand or mud, depress the accelera-
tor pedal slightly and move the selector le-
ver back and forth between “D” and “R” re-
peatedly. Do not race the engine. For the
best possible traction, avoid spinning the
wheels when trying to free the vehicle.
y When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT).
y Never equip your vehi cle with tires larg-
er than those specified in this manual.
y Wash the vehicle’s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they
need to be washed thoroughly.
y Frequent driving of an AWD vehicle un-
der hard-driving condit ions such as rough
roads or off roads will necessitate more
frequent replacement of engine oil, brake
fluid and transmission oil than that speci-
fied in the maintenance schedule de-
scribed in the “Warranty and Maintenance
Booklet”.
Remember that damage done to your
SUBARU while operating it off-road and
not using common sense precautions
such as those listed above is not eligible
for warranty coverage. Winter driving
„ Operation during cold weath-
er Carry some emergency equipment, such
as tire chains, a window scraper, a bag of
sand, flares, a small shovel, and jumper
cables.
Check the battery and cables. Cold tem-
peratures reduce battery capacity. The
battery must be in good condition to pro-
vide enough power for cold winter starts.
Use an engine oil of proper grade and vis-
cosity for cold weather. Heavy summer oil
will cause harder starting.
Keep the door locks from freezing by 800015

squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the ru bber weather strips
around the door. If the door is frozen, use
hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes be-
cause they may damage the paint of the
vehicle.
SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing temper-
ature varies according to how much it is di-
luted, as indicated in the following table.
In order to prevent freezing of washer flu-
id, check the freezing temperatures in the
table above when adjusting the fluid con-
centration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside tem-
perature, it may freeze and block the noz-
zles.
T Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and dan-
gerous.
While warming up the vehicle before driv-
ing, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has accu-
mulated under the fenders to avoid mak-
ing steering difficult. During severe winter
driving, stop when and where it is safe to do so and check under the fenders period-
ically.
T Parking in cold weather
Do not use the parking brake when park-
ing for long periods in cold weather since
it could freeze in that position. Instead, ob-
serve the following.
1. Place the shift lever in “1” or “R” for
manual transmission vehicles, and in “P”
for automatic trans mission vehicles.
2. Use tire stops under the tires to prevent
the vehicle from moving.
When the vehicle is parked in snow or
when it snows, raise the wiper blades off
the glass to prevent damage to them.
When the vehicle has been left parked af-
ter use on roads heavily covered with
snow, or has been left parked during a
snowstorm, icing may develop on the
brake system, which could cause poor
braking action. Check for snow or iceWasher Fluid

gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the engine
running.
