NOTEWhen the control dial is turned fully
upward, the illumination brightness
becomes the maximum and the auto-
matic dimming function does not work
at all.
 The brightness setting is not
canceled even when the ignition switch
is turned to th e “OFF” position.■Auto Dimmer Cancel Func -
tionWhen the ambient light is bright, the illumi-
nation brightness is set to the maximum
regardless of the position of the control
dial. In this case, you cannot adjust the
illumination brightness by using the

Warning and Indicator Lights
140■ABS Warning LightThe ABS warning light illuminates
together with the brake system warning
light if the EBD system malfunctions. For
further details of the EBD system malfunc- tion warning, refe
r to "Brake System
Warning Light" P140.
NOTEIf the warning light behavior is as
described in the following conditions,
the ABS may be considered normal.
 The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
 The warning light remains illumi-
nated after the engine has been
started, but it turns off while driving.
 The warning light illuminates during
driving, but it turns off immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warn ing light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will turn off.
■ Brake System
Warning LightThis light has the following functions.
▼ Parking brake warning
The light illuminates with the parking
brake applied while the ignition switch is in
the “ACC” or “ON” position. It turns off
when the parking brake is fully released.
▼ Brake fluid level warningThis 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.
CAUTION
 If any of the following conditions
occur, we recommend that you
have the ABS (Anti-Lock Brake
System) repaired at the first avail-
able opportunity by your
SUBARU dealer.
- The warning light does not
illuminate when the ignition
switch is turned to the “ON”
position.- The warning light illuminates
when the ignition switch is
turned to the “ON” position,
but it does no t turn off even
after starting the vehicle.- The warning light illuminates
during driving.
 When the warning light is on (and
brake system warning light is off),
the ABS function shuts down;
however, the conventional brake
system continues to operate
normally.
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 illuminated,
have the brakes inspected by a
SUBARU dealer immediately. 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.

Warning and Indicator Lights
142force will be restored after the steering
wheel is not operated for a while and
the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes
power assist limitation to occur too
frequently, that may result in a mal-
function of the power steering control
system.■ TRAC OFF Indicator
LightThis light illuminates when the TRAC
system is off. For detai ls, refer to "Vehicle
Stability Control ( VSC)/TRAC System"
 P247.
■ Vehicle Stability
Control (VSC)
Warning Light/Vehicle
Stability Control (VSC) Oper -
ation Indicator Light▼ Vehicle Stability Control (VSC)
warning light
NOTEIf the electrical circuit of the Vehicle
Stability Control (VSC) system itself
malfunctions, the warning light only
illuminates. At this time, the ABS (Anti-
lock Brake System) remains fully oper-
ational.
 The warning light illuminates when
the electronic control system of the
ABS/Vehicle Stability Control (VSC)
system malfunctions.
The Vehicle Stability Control (VSC)
system is probably inoperative under any
of the following conditions. Have your
vehicle checked at a SUBARU dealer
immediately.
 The warning light does not illuminate
when the ignition switch is turned to the
“ON” position.
 The warning light illuminates while the
vehicle is running.NOTEIf the warning light behavior is as
described in the following examples,
the Vehicle Stability Control (VSC) sys-
tem may be considered normal.
 The warning light illuminates right
after the engine is started but turns off
immediately and remains off.
 The warning light illuminates after
the engine has started and turns off
CAUTION
The Vehicle Stability Control (VSC)
system provides its ABS control
through the electrica l circuit of the
ABS. Accordingly, if the ABS is
inoperative, the Vehicle Stability
Control (VSC) system becomes
unable to provide ABS control. As a
result, the Vehicle Stability Control
(VSC) system becomes inoperative,
causing the warning light to illumi-
nate. Although both the Vehicle Sta-
bility Control (VSC) and ABS are
inoperative in this case, the ordi-
nary functions of the brake system
are still available. You will be safe
while driving in this condition, but
drive carefully and have your vehi-
cle checked at a SUBARU dealer as
soon as possible.

Braking
244▼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
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 a dual circuit brake
system. 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 vacuum pump
system to assist brakin g 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.
▼ Supplemental booster function
when vacuum pressure fails
While the ignition switch is turned “ON”
and the engine is running, the supple-
mental booster function operates when
the brake booster performance is
decreased due to insufficient vacuum
boost.
When the brake pedal is depressed while
the supplemental booster function is oper-
ating, an operation sound and brake pedal
vibration may be generated. This is not a
malfunction.
▼ Brake assist system
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-
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.
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.

ABS (Anti-Lock Brake System)
245
Starting and Operating7
■Disc Brake Pad Wear
Wa rning IndicatorsThe 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, imme-
diately have your vehicle inspected by the
nearest SUBARU dealer.
7-11. ABS (Anti-Lock BrakeSystem)
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 f eel a slight vibration
in the brake pedal. This is normal when
the ABS operates.■ ABS Self-CheckYou 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 LightRefer to "ABS Warning Light" P140.
700040
WARNING
Always use the utmost care in driv-
ing – overconfidence because you
are driving with an ABS equipped
vehicle could easily lead to a seri-
ous accident.
CAUTION
 The ABS does not always
decrease 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 newly fallen snow, stopping
distances may be longer for a
vehicle with the ABS than one
without. When driving under
these conditions, therefore,
reduce your speed and leave
ample distance from other vehi-
cles.
 When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since doing
so may defeat the operation of the
ABS.
