warning
WARNING
Engine exhaust, some of its consti-
tuents, and certain vehicle compo-
nents contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm. In addi-
tion, certain fluids in vehicles and
certain components of product wear
contain or emit chemicals known to
the State of California to cause
cancer and birth defects or other
reproductive harm.&California Perchlorate Advi-
soryCertain vehicle components such as air-
bag modules, seatbelt pretensioners and
keyless entry transmitter batteries may
contain perchlorate material. Special
handling may apply for service or vehicle
end of life disposal. See www.dtsc.ca.gov/
hazardouswaste/perchlorate.
&Noise from under the vehicle
NOTEYou may hear a noise from under the
vehicle approximately 5 to 10 hours
after the engine is turned off. However,
this does not indicate a malfunction.
This noise is caused by the operation of
the fuel evaporation leakage checking
system and the operation is normal.
The noise will stop after approximately
15 minutes.&Event data recorderThis vehicle is equipped with an event data
recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a
vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to
record such data as:
.How various systems in your vehicle
were operating;
.Whether or not the driver and passen-
ger safety belts were buckled/fastened;
.Howfar(ifatall)thedriverwas
depressing the accelerator and/or brakepedal; and,
.How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data are recorded by your vehicle
only if a non-trivial crash situation occurs;
no data are recorded by the EDR under
normal driving conditions and no personal
data (e.g., name, gender, age, and crash
location) are recorded. However, other
parties, such as law enforcement, could
combine the EDR data with the type of
personally identifying data routinely ac-
quired during a crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the
vehicle or the EDR is needed. In addition
to the vehicle manufacturer, other parties,
such as law enforcement, that have the
special equipment, can read the informa-
tion if they have access to the vehicle or
the EDR.

!Brake fluid level warning
This light illuminates 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
illuminate 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
reservoir, do not drive the vehicle. Have
the vehicle towed to the nearest SUBARU
dealer for repair.
!Electronic Brake Force Distribution
(EBD) system warning
The brake system warning light also
illuminates if a malfunction occurs in the
EBD system. In that event, it illuminates
together with the ABS warning light.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
while driving.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be moreprone to locking when the brakes are
applied 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, apply the
parking brake and then restart it.
3. Release the parking brake. If both
warning lights turn off, the EBD system
may be malfunctioning. Drive carefully to
the nearest SUBARU dealer and have the
system inspected.
4. If both warning lights illuminate again
and remain 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
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
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.!Electronic parking brake system
warning (models with electronic
parking brake system)
The brake system warning light illuminates
when the electronic parking brake system
is malfunctioning. If the warning light
illuminates, promptly park in a safe loca-
tion as soon as possible and contact your
SUBARU dealer.
The brake system warning light remains
illuminated when the parking brake cannot
be released even if the parking brake
switch is pushed. For details, refer to
“Electronic parking brake (models with
electronic parking brake system)”F7-43.
!Frequent operation warning
The brake system warning light illuminates
and a chirp sound will be heard if the
parking brake switch is operated too
frequently. In this case, the operation of
the parking brake switch is restricted to
protect the electronic parking brake sys-
tem.
!Vacuum pump system warning (ex-
cept STI)
This light illuminates when a malfunction is
detected in the vacuum pump system.

CAUTION
Trapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.NOTEEngine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
Starting and stopping the en-
gine&General precautions when
starting/stopping engine
WARNING
.Never start the engine from out-
side the vehicle. It may result in
an accident.
.Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can cre-
ate a fire hazard at high tempera-
tures.
.Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
CAUTION
.Do not stop the engine while
driving. Otherwise, the catalyst
may overheat and burn.
.When starting the engine, be sureto sit in the driver’s seat (except
when using the remote engine
start system).
NOTE.Avoid rapid acceleration immedi-
ately after the engine has started. In
addition, always avoid rapid racing.
.Until the engine is warmed up suffi-
ciently, the engine speed is maintained
high. The engine speed will gradually
drop as the engine warms up.
.On rare occasions, it may be difficult
to start the engine depending on the
fuel used and the driving condition
(repeated short trips when the engine
is not warmed up sufficiently). In such
cases, it is recommended to switch to a
different brand of fuel.
.On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly such
as a rapid start-up and a rapid accel-
eration. This is not a malfunction.
.The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.
.It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically

Continuously variable trans-
missionThe continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
WARNING
Do not shift from the“P”or“N”
position into the“D”or“R”position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.
CAUTION
.Observe the following precau-
tions. Otherwise, the transmis-
sion could be damaged.
–Shift into the“P”or“R”posi-
tion only after the vehicle has
completely stopped.
–Do not shift from the“D”
position into the“R”position
or vice versa until the vehicle
has completely stopped.
.Do not race the engine for more
than 5 seconds in any position
except the“N”or“P”positionwhen the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
.Never move the vehicle as fol-
lows. Doing so may result in an
unexpected accident or malfunc-
tion.
–Moving rearward by inertia
with the select lever set in a
forward driving position.
–Moving forward by inertia with
the select lever set in the“R”
position.
.When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the“P”position. Do not park for a
long time with the select lever in
any other position as doing so
could result in a dead battery.
NOTE.When the engine coolant tempera-
ture is still low, the transmission will
upshift to higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automaticallyshift to the normal timing after the
engine has warmed up.
.Immediately after transmission fluid
is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
.When driving under continuous hea-
vy load conditions such as when climb-
ing a long, steep hill, the engine speed
or the vehicle speed may automatically
be reduced. This is not a malfunction.
This phenomenon results from the
engine control function maintaining
the cooling performance of the vehicle.
The engine and vehicle speed will
return to a normal speed when the
engine is able to maintain the optimum
cooling performance after the heavy
load decreases. Take extremely care
when driving under a heavy load.
.The continuously variable transmis-
sion is a chain type system that pro-
vides superior transmission efficiency
for maximum fuel economy. At times,
depending on varying driving condi-
tions, a chain operating noise may be

Braking&Braking tips
WARNING
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.
!When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing the
brake pedal to heat up the brakes.
!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.
!Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could causea loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe place.
&Brake system!Two separate circuits
Your vehicle has two separate circuit brake
systems. Each circuit works diagonally
across the vehicle. If one circuit of the
brake system should fail, the other half of
the system 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.
!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, resulting 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 depress the pedal much harder
than normal and the braking distance will
increase.!Brake assist system
WARNING
Do not be overconfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.
CAUTION
When you need to brake suddenly,
continue depressing the brake pedal
strongly to obtain the effect of the
brake assist.
Brake assist is a driver assistance system.
It assists the brake power when the driver
cannot depress the brake pedal strongly
and the brake power is insufficient.
Brake assist generates the brake power
according to the speed at which the driver
depresses the brake pedal.NOTEWhen you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi-

Electronic Brake Force Dis-
tribution (EBD) systemThe 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 and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
system malfunction, 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
malfunctionsBrake and ABS warning lightIf a malfunction occurs in the EBD system,
the system stops working and the brake
system warning light and ABS warning
light illuminate simultaneously.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
while driving.
Even if the EBD system malfunctions, the
conventional braking system will still func-
tion. However, the rear wheels will be more
prone to locking when the brakes are
applied 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
location.
2. Apply the parking brake and turn off the
engine.
3. Restart the engine.
4. Release the parking brake.
Even if both warning lights turn off:
The EBD system may be malfunctioning.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
If both warning lights illuminate again
and remain illuminated after restarting
the engine:
1. Turn off the engine again.
2. Apply the parking brake.
3. Check the brake fluid level. For details
about checking the brake fluid level, refer
to“Checking the fluid level”F11-24.
.If the brake fluid level is not below the
“MIN”mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
.If the brake fluid level is below the“MIN”
mark, DO NOT drive the vehicle. Instead,
have the vehicle towed to the nearest

conditions than a two wheel drive vehicle.
There is little difference in handling, how-
ever, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure to
reduce your speed and maintain an ample
distance from other vehicles.
.Always check the cold tire pressure
before starting to drive. The recommended
tire pressure is provided on the tire
placard, which is located under the door
latch on the driver’s side.
.Frequent driving of an AWD vehicle
under hard-driving conditions such as
steep hills or dusty roads will necessitate
more frequent replacement of the follow-
ing items than that specified in the“War-
ranty and Maintenance Booklet”.
–Engine oil
–Brake fluid
–Rear differential gear oil
–Manual transmission oil (MT mod-
els)
–Continuously variable transmission
fluid (CVT models)
–Front differential gear oil (CVT
models)
.There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to“Towing”
F9-21.
Driving precautionWater entering the engine air intake or the
exhaust pipe or water splashing onto
electrical parts may damage your vehicle
and may cause it to stall. Never attempt to
drive through rushing water; regardless of
its depth, it can wash away the ground
from under your tires, resulting in possible
loss of traction and even vehicle rollover.
Winter driving&Operation during cold weath-
erCarry some emergency equipment, such
as 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
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by
squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber 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
because they may damage the paint of
the vehicle.
