position and goes out after approximately
2 seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, the ABS system may not
be working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally. . The warning light does not come
on when the ignition switch is
turned to the “ON ”position.
. The warning light comes on when
the ignition switch is turned to the “ON ”position, but it does not
go out even when the vehicle
speed exceeds approximately 8
mph (12 km/h).
. The warning light comes on dur-
ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer. NOTE
If the warning light behavior is as
described in the following, the ABS
system may be considered normal. .
The warning light comes on right
after the engine is started but goes out
immediately, remaining off.. The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).. The warning light comes on during
driving, but it goes out immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out. Electronic Brake 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 braking 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 ABSsystem ’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
Vehicle with SI-DRIVE
Vehicle without SI-DRIVE
If a malfunction occurs 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 driving.
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
applied harder than usual and the vehi-cle
’s motion may therefore become some-
what 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 systeminspected.
6. If the brake fluid level is below the “ MIN ”mark, DO NOT drive the vehicle.
Instead, have the vehicle towed to the
nearest SUBARU dealer for repair.
WARNING
. Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
. If at all in doubt about whether
the brakes are operating prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair. Starting and operating

Control system; if any should occur, have
an authorized SUBARU dealer carry out
an inspection of the system at the first
available opportunity. .The warning light does not turn on
when the ignition switch is turned to the
ON position. . The warning light turns on while the
vehicle is being driven.. When a malfunction has occurred in
the Vehicle Dynamics Control electrical
system, only the warning light will turn on.
In such an event, the ABS will still be
operating normally. . The warning light will also turn on when
a problem occurs with the ABS or Vehicle
Dynamics Control electronic control sys- tems.
Because the Vehicle Dynamics Control
system controls each brake through the
ABS, whenever the ABS stops operating
due to a malfunction in that electrical
system, the Vehicle Dynamics Control will
also become unable to control all four
brakes. Thus Vehicle Dynamics Control
system operation halts and the warning
light turns on. Although both the Vehicle
Dynamics Control system and the ABS
will be inoperable in this situation, it will
still be possible to stop the vehicle using
normal braking. The Vehicle Dynamics Control system and the ABS do not
adversely affect operation of the vehicle
in any way when they are inoperable;
however should such a situation occur,
drive with care and have an authorized
SUBARU dealer carry out an inspection of
those systems at the first available oppor-
tunity.
NOTE
When the warning light turns on and off
in the following way, it indicates that
the Vehicle Dynamics Control system
is operating normally. . Although turning on after the engine
has been started, the warning light
quickly turns off and stays off.. The warning light turns on when the
vehicle is being driven; it then turns off
and stays off. ! Vehicle Dynamics Control OFF in-
dicator light
This light comes on to indicate that the
Vehicle Dynamics Control system is in
non-operation mode. This does not con-
stitute failure of the Vehicle Dynamics
Control system. NOTE . The indicator light may stay on for a
while after the engine has been started, especially in cold weather. This occurs
because the engine has not yet
warmed up and is completely normal.
The light will turn off when the engine
has reached a suitable operating tem-perature..
When an engine problem occurs
and the CHECK ENGINE warning light/
malfunction indicator lamp turns on,
the indicator light will also come on.
The following two situations could indicate
malfunction of the Vehicle Dynamics
Control system; if either should occur,
have an authorized SUBARU dealer carry
out an inspection of that system at the first
available opportunity. . The indicator light does not turn on
when the ignition switch is turned to the
ON position. . The indicator light fails to turn off after
the engine is started, even when several
minutes have passed to allow the engine
to heat up sufficiently. Starting and operating

you should not deactivate the Vehicle
Dynamics Control system except under
above-mentioned situations. NOTE . When the switch has been pressed
to deactivate the Vehicle Dynamics
Control system, the Vehicle Dynamics
Control system automatically reacti-
vates itself the next time the ignition
switch is turned to the “LOCK ”position
and the engine is restarted.. If the switch is held down for 10
seconds or longer, the indicator light
goes off, the Vehicle Dynamics Control
system is activated, and the system
ignores any further pressing of the

sary.

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
thepipingistoolowfortheoutside
temperature, it may freeze and block thenozzles.
CAUTION
Adjust the washer fluid concentra-
tion appropriately for the outside
temperature. If the concentration is
inappropriate, sprayed washer fluid
may freeze on the windshield and
obstruct your view, and the fluid
may freeze in the reservoir tank.
! Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery anddangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has
accumulated under the fenders to avoid
making steering difficult. During severe winter driving, stop when and where it is
safe to do so and check under the fenders
periodically. !
Parking in cold weather
WARNING
Snow can trap dangerous exhaust
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 enginerunning.
Do not use the parking brake when
parking for long periods in cold weather
since it could freeze in that position.
Instead, observe the following.
1. Place the shift lever in “1 ” or “R ” for
manual transmission vehicles, and in “P ”
for automatic transmission 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
after 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 ice
buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,
being careful not to damage the disc
brakes and brake hoses and ABS har-ness. !
Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used
for an extended period, it is best to have
the fuel tank filled to capacity. & Driving on snowy and icy roads
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control. Driving tips
8-9
– CONTINUED –

8-10Driving tips
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’s intake system and may
hinder the air flow, which could
result in engine shutdown or evenbreakdown.
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle ’s braking perfor-
mance on snowy and icy roads. Refer tothe “ABS (Anti-lock Brake System) ”and
“ Vehicle Dynamics Control system ”sec-
tion in chapter 7 for information on braking
on slippery surfaces. !
Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window. If the wiper
blades are frozen to the windshield or rear
window, use the defroster with the airflow
control button/dial in the “
”position and
the temperature control dial set for max-
imum warmth until the wiper blades are
completely thawed out. If your vehicle is
equipped with a wiper deicer, it is helpful
to thaw the windshield wiper blades. To
thaw out the rear wiper blade, use the rear
window defogger.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
with the airflow control button/dial in “
”
and the temperature control dial set for
maximum warmth. After the windshield
gets warmed enough to melt the frozen
snow on it, wash it away using the
windshield washer.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
We recommend use of non-freezing type wiper blades (winter blades) during the
seasons you could have snow and sub-
zero temperatures. Blades of this type
give superior wiping performance in
snowy conditions. Be sure to use blades
that are suitable for your vehicle.
CAUTION
During high-speed driving, non-
freezing type wiper blades may not
perform as well as standard wiper
blades. If this happens, reduce the
vehicle speed.
NOTE
When the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades. & Corrosion protection
Refer to the “Corrosion protection ”section
(chapter 10).

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.

!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 water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT models) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air
conditioner and stop the vehicle at the
nearest safe place. Refer to the “Engine
overheating ”section in chapter 9, and
“ Warning and indicator lights ”section in
chapter 3. NOTE
With AT models, the temperature of
engine coolant is less likely to rise to
the OVERHEAT zone in the “D ” posi-
tion than in the manual mode position. . 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. !
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) or “P ” (automatic transmis-
sion) and shut off the engine. Driving tips

Brake fluid &Checking the fluid level
WARNING
. Never let brake fluid contact your
eyes because brake fluid can be
harmful to your eyes. If brake
fluid gets in your eyes, immedi-
ately flush them thoroughly with
clean water. For safety, when
performing this work, wearing
eye protection is advisable.
. Brake fluid absorbs moisture
from the air. Any absorbed moist-
ure can cause a dangerous loss
of braking performance.
. If the vehicle requires frequent
refilling, there may be a leak. If
you suspect a problem, have the
vehicle checked at your SUBARU
dealer.
CAUTION
. Never use different brands of
brake fluid together. Also, avoid
mixing DOT 3 and DOT 4 brake
fluids even if they are of the samebrand. .
When adding brake fluid, be care-
ful not to allow any dirt into the
reservoir.
. Never splash the brake fluid over
painted surfaces or rubber parts.
Alcohol contained in the brake
fluid may damage them.
. Be careful not to spill brake fluid
when adding it. If brake fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If brake fluid gets on the
exhaust pipe, be sure to wipe itoff.
Check the fluid level monthly.
Check the fluid level on the outside of the
reservoir. If the level is below “MIN ”, add
the recommended brake fluid to “MAX ”. Use only brake fluid from a sealed
container.
