tion of a motor vehicle in an
enclosed environment can cause
a harmful build-up of Carbon
Monoxide. Carbon Monoxide is
harmful to your health. Exposure
to high levels of Carbon Monox-
ide can cause headaches, dizzi-
ness or in extreme cases uncon-
sciousness and/or death.
.Before performing any servicing
of the vehicle, temporarily place

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
youaredrivingwithanABS
equipped vehicle could easily lead
to a serious accident.
CAUTION
.The ABS does not always de-
crease stopping distance. You
should always maintain a safe
following distance from other
vehicles.
.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 than
one without. When driving under
these conditions, therefore, re-
duce your speed and leave ample
distance from other vehicles.
.When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do notpump the brake pedal since
doing so may defeat the opera-
tion of the ABS.
The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.
When the ABS 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 will not operate when the vehicle
speed is below approximately 6 mph (10
km/h).
&ABS self-check
You may feel a slight shock in the brake
pedal and hear the operating noise of the
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
being carried out and does not indicate
any abnormal condition.
&ABS warning light
Refer to“ABS warning light”F3-18.
Starting and operating/ABS (Anti–lock Brake System)7-33

Starting and operating/Electronic Brake Force Distribution (EBD) system
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 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
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
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.
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”F11-19.
.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
7-34

.Hill descent control function:
Using the hill descent control function, you
can keep the vehicle at a consistent speed
driving downhill. If the vehicle speed is
likely to increase, the brake control system
will be activated to adjust the vehicle
speed.
.Driving ability control:
This mode increases the hill-climbing
ability and driving ability as well as
enabling smooth application of torque for
easier control of the steering wheel.
&To activate/deactivate the X-
mode
X-mode switch
X-mode indicator
To activate:
Press the X-mode switch. While the X-
mode is activated, the X-mode indicator
appears.
To deactivate:
Press the X-mode switch again. The X-
mode indicator will disappear when the X-
mode is deactivated.
NOTE
.Even if you try to activate the X-
mode by pressing the X-mode switch
when the vehicle speed is 12 mph (20
km/h) or more, the X-mode will not be
activated. At this time, a buzzer will
sound twice.
.If the vehicle speed reaches 25 mph(40 km/h) or more while the X-mode is
activated, a buzzer will sound once and
the X-mode will be deactivated.
.While the engine is running, if either
of the following conditions is met, the
X-mode will be deactivated. In this
case, it is not possible to activate the
X-mode.
–The CHECK ENGINE warning
light/malfunction indicator light illu-
minates.
–The AT OIL TEMP warning light
flashes.
–The ABS warning light illumi-
nates.
–The Vehicle Dynamics Control
warning light illuminates.
.If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to activate
the X-mode. Even while the X-mode is
activated, the X-mode will be deacti-
vated when the engine coolant tem-
perature increases.
&Hill descent control function
The hill descent control function will be in
standby mode when the X-mode is acti-
vated and the vehicle speed is less than
approximately 12 mph (20 km/h).

exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
.Keep the trunk lid (Legacy) or
rear gate (Outback) closed while
driving to prevent exhaust gas
from entering the vehicle.
NOTE
Due to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the ex-
haust system for a short time after the
engine has been shut off. This sound is
normal.
Catalytic converter
WARNING
.Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.
grass, paper, rags or leaves),
because the catalytic converter
operates at very high tempera-
tures.
.Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.
2.5 L models
3.6 L models
The catalytic converter is installed in the
exhaust system. It serves as catalyst to
reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust.
To avoid damage to the catalytic conver-
ter:
.Use only unleaded gasoline. Even a
small amount of leaded gasoline will
damage the catalytic converter.
.Never start the engine by pushing or
pulling the vehicle.
.Avoid racing the engine.
.Never turn off the ignition switch while
the vehicle is moving.
.Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
