7-24Starting and operating
!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 bring 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. NOTE
When you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi- cate any malfunctions, and the brake
assist system is operating properly. .
You might feel that the brake pedal
is applied by lighter force and gener-
ates a greater braking force.. You might hear the sound of ABS
operating from the engine compart-ment.
& Disc brake pad wear warning indicators
The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, im-
mediately have your vehicle inspected by
the nearest SUBARU dealer. ABS (Anti-lock Brake Sys- tem)
WARNING
Always use the utmost care in driving –overconfidence because
you are driving with an ABS
equipped vehicle could easily lead
to a serious accident.
CAUTION
. The ABS system does not always
decrease stopping distance. You
should always maintain a safe
following distance from othervehicles.
. When driving on badly surfaced
roads, gravel roads, icy road, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS
system than one without. When
driving under these conditions,
therefore, reduce your speed and
leave ample distance from othervehicles.
. When you feel the ABS system
operating, you should maintain

constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the
operation of the ABS system.
The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road sur-
faces. This helps prevent the loss of
steering control and directional stability
caused by wheel lock-up.
When the ABS system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
when the ABS operates.
The ABS system will not operate when the
vehicle speed is below approximately 6
mph (10 km/h). & ABS system self-check
You may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
system being carried out and does not
indicate any abnormal condition. & ABS warning light
Refer to “ABS warning light ”F 3-16. 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 malfunctions
If 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
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 Starting and operating
7-25
– CONTINUED –

7-26Starting and operating
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 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. Refer to “Brake fluid ”
F 11-25.
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.
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. Vehicle Dynamics Control system
WARNING
Always use the utmost care in driving –overconfidence because
you are driving with a Vehicle Dy-
namics Control system equipped
vehicle could easily lead to a ser-
ious accident.
CAUTION
. Even if your vehicle is equipped
with Vehicle Dynamics Control
system, winter tires should be
used when driving on snow-cov-
ered or icy roads; in addition,
vehicle speed should be reduced
considerably. Simply having a
Vehicle Dynamics Control sys-
tem does not guarantee that the
vehicle will be able to avoid
accidents in any situation.
. Activation of the Vehicle Dy-
namics Control system is an
indication that the road being
travelled on has a slippery sur-
face; since having Vehicle Dy-
namics Control is no guarantee

that full vehicle control will be
maintained at all times and under
all conditions, its activation
should be seen as a sign that
the speed of the vehicle should
be reduced considerably.
. Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle equipped with the Vehicle
Dynamics Control system, have
an inspection of that system
performedbyanauthorized
SUBARU dealer.
. The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Con-
trol system is operating properly. – All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, the amount of wear
should be the same for all
four tires.
– Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to
the driver ’s side door pillar.
– Use only the specified tem-
porary spare tire to replace a
flat tire. With a temporary spare tire, the effectiveness of
the Vehicle Dynamics Control
system is reduced and this
should be taken into account
when driving the vehicle in
such a condition.
. If non-matching tires are used,
the Vehicle Dynamics Control
system may not operate cor-
rectly.
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine ’s output and the
wheels ’respective braking forces to help
maintain traction and directional control. . Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is indicated by
flashing of the Vehicle Dynamics Control
operation indicator light. . Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels ’tendency to slide
sideways during steering operations. Acti- vation of this function is indicated by
flashing of the Vehicle Dynamics Control
operation indicator light.
NOTE . The Vehicle Dynamics Control sys-
tem may be considered normal when
the following conditions occur.
–Slight twitching of the brake
pedal is felt. – The vehicle or steering wheel
shakes to a small degree.– An operating sound from the
engine compartment is heard
briefly when starting the engine
and when driving off after starting
the engine. – The brake pedal seems to jolt
when driving off after starting the engine.
. In the following circumstances, the
vehicle may be less stable than it feels
to the driver. The Vehicle Dynamics
Control System may therefore operate.
Such operation does not indicate a
system malfunction.
–on gravel-covered or rutted
roads – on unfinished roads
– when the vehicle is towing a
trailer– when the vehicle is fitted with Starting and operating

. Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly
different compared to that for normalconditions. . It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with
Vehicle Dynamics Control. . Always turn off the engine before
replacing a tire as failure to do so may
render the Vehicle Dynamics Control
system unable to operate correctly. & Vehicle Dynamics Control

OFF switch
Pressing the switch to deactivate the
Vehicle Dynamics Control system can
facilitate the following operations. .a standing start on a steeply sloping
road with a snowy, gravel-covered, or
otherwise slippery surface . extrication of the vehicle when its
wheels are stuck in mud or deep snow
When the switch is pressed during engine
operation, the Vehicle Dynamics Control
OFF indicator light on the combination
meter illuminates. The Vehicle Dynamics
Control system will be deactivated. When
the switch is pressed again to reactivate
the Vehicle Dynamics Control system, the
Vehicle Dynamics Control OFF indicator light turns off.
You should not deactivate the Vehicle
Dynamics Control system except under
the above-mentioned situations.
CAUTION
The Vehicle Dynamics Control sys-
tem helps prevent unstable vehicle
motion such as skidding using con-
trol of the brakes and engine power.
Do not turn off the Vehicle Dynamics
Control system unless it is abso-
lutely necessary. If you must turn off
the Vehicle Dynamics Control sys-
tem, drive very carefully based on
the road surface condition.
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
turns off, the Vehicle Dynamics Control
system is activated, and the system
ignores any further pressing of the
switch. To make the switch usable

low pressure threshold, the low tire
pressure warning light should turn
off a few minutes later.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of
the tire pressure sensors. If the light
illuminates steadily after blinking for
approximately one minute, promptly
contact a SUBARU dealer to have
the system inspected.CAUTION
Do not place metal film or any metal
parts under the driver ’s seat. This
may cause poor reception of the
signals from the tire pressure sen-
sors, and the tire pressure monitor-
ing system will not function prop-
erly.

WARNING
. Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to them.
. Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
. Be sure to stop the engine if you
take a nap in the vehicle. If
engine exhaust gas enters the
passenger compartment, occu-
pants in the vehicle could die
from carbon monoxide (CO) con-
tained in the exhaust gas.

WARNING
. Before exiting the vehicle, make
sure that you turn off the engine.
Otherwise, the parking brake
may be released and an accident
may occur.
. If the brake system warning light
flashes, the electronic parking
brake system may be malfunc-
tioning. Immediately stop your
vehicle in a safe location, use
tire stops under the tires to
prevent the vehicle from moving and contact your SUBARU deal-
er.
CAUTION
. When the electronic parking
brake system has a malfunction
and the parking brake cannot be

8-2Driving tips
New vehicle break-in driving –the first 1,000 miles (1,600
km)
The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km): . Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency. . Do not drive at one constant engine or
vehicle speed for a long time, either fast or
slow. . Avoid starting suddenly and rapid
acceleration, except in an emergency.. Avoid hard braking, except in an
emergency.
The same break-in procedures should be
applied to a newly installed or overhauled
engine or when brake pads or brake
linings are replaced with new ones. Fuel economy hints
The following suggestions will help to save
your fuel. .
Select the proper gear position for the
speed and road conditions.. Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long aspossible. . Do not pump the accelerator and avoid
racing the engine.. Avoid unnecessary engine idling.
. Keep the engine properly tuned.
. Keep the tires inflated to the correct
pressure shown on the tire placard, which
is located under the door latch on thedriver ’s side. Low pressure will increase
tire wear and fuel consumption. . Use the air conditioner only when
necessary.. Keep the front and rear wheels in
proper alignment.. Avoid carrying unnecessary luggage or
cargo.. The indication of the ECO gauge
shows a reference for saving fuel. For
details, refer to “ECO gauge ”F 3-8. Engine exhaust gas (carbon
monoxide)
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from enter-
ing the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked
vehicle for a long time while the
engine is running. If that is
unavoidable, then use the venti-
lation fan to force fresh air into
the vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.
. If at any time you suspect that
