Warning and Indicator Lights
141
Instruments and Controls3
– CONTINUED –
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 reser-
voir, do not drive the vehicle. Have the
vehicle towed to the nearest SUBARU
dealer for repair.▼ Electronic Brake Force Distribution
(EBD) system warning
If the warning light remains on even
though the parking brake is released, the
brake fluid level may be low or there could
be a problem with the EBD system. Park
the vehicle in a safe place immediately
and contact a SUBARU dealer.
▼ Vacuum pressure system warning
The brake system warning light will illumi-
nate when the vacuum pressure sensor is
malfunctioning or brake booster pressure
is decreasing. If the light continues to illu-
minate for several minutes after starting
the engine, there may be a malfunction in
the vacuum system. In this case, drive the
vehicle carefully and have the system
inspected by a SUBARU dealer.
■ Low Fuel Warning LightThe low fuel warning light illuminates
when the tank is nearly empty approxi-
mately 1.8 US gal (7.0 liters, or 1.5 Imp
gal). It only operates when the ignition
switch is in the “ON” position.■ Door Open IndicatorWhen any of the doors or the trunk lid is
not fully closed, the door open indicator
appears. This function is effective even if
the ignition switch is in the “OFF” or “ACC”
position.
The open door is indicated by the corre-
sponding part of the door open indicator.
Always make sure this indicator does not
appear before you start to drive.■ Power Steering
Warning LightWhile the engine is running, a warning
light illuminates and a buzzer sounds if a malfunction is detected in the electric

power steering system.
NOTEIf the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent
the system components, such as the
control computer and drive motor,
from overheating.
 The steering wheel is operated
frequently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently
turning the steering wheel during
parallel parking.
 The steering wheel remains in the
fully turned position for a long period
of time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light illu-
minates. Engine misfires as a result
of an empty tank could cause dam-
age to the engine.
CAUTION
When the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.
