Instruments and controls/Warning and indicator lights

! 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
during driving.
Even if the EBD system fails, the conventional 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 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.

! Vacuum pump system warning (except STI)
This light illuminates when a malfunction
is detected in the vacuum pump system.

NOTE
The vacuum pump system assists the
boost pressure when driving at high
altitudes while the engine is cold.

& Low fuel warning light
The low fuel warning light illuminates
when the tank is nearly empty, at approximately 2.6 US gal (10.0 liters, 2.2 Imp gal).
It only operates when the ignition switch is
in the “ON” position.

CAUTION
Promptly put fuel in the tank whenever the low fuel warning light
illuminates. Engine misfires as a
result of an empty tank could cause
damage to the engine.

NOTE
This light does not turn off unless the
tank is replenished up to an internal
fuel quantity of approximately 4.5 US
gal (17 liters, 3.7 Imp gal).
