ABS warning light
CAUTION
. If any of the following conditions
occur, we recommend that you
have the ABS system repaired at
the first available 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 not turn off even
when the vehicle speed ex-
ceeds approximately 8 mph
(12 km/h).
– The warning light illuminates
during driving.
. When the warning light is on (and
the brake system warning light is
off), the ABS function shuts
down. However, the conventional
brake system continues to oper-
ate normally.
With a vehicle equipped with an EBD
system, the ABS warning light illuminates together with the brake system warning
light if the EBD system malfunctions. For
further details of the EBD system mal-
function warning, refer to
“Electronic
Brake Force Distribution (EBD) system
warning ”F 3-22.
NOTEIf the warning light behavior is as
described in the following conditions,
the ABS system 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 when the vehicle speed
reaches approximately 8 mph (12
km/h).
. 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 warning 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 light
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 prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair.
This light has the following functions.
! Parking brake warning
The light illuminates with the parking
brake applied while the ignition switch is
in the “ON”position. It turns off when the
parking brake is fully released.
! 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.

Instruments and controls
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 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 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.
&
Low fuel warning light
The low fuel warning light illuminates
when the tank is nearly empty approxi-
mately 2.6 US gal (10.0 liters, or 2.2 Imp
gal). It only operates when the ignition
switch is in the “ON”position. When this light illuminates, fill the fuel tank immedi-
ately.
NOTEThis light does not turn off unless the
tank is replenished up to an internal
fuel quantity of approximately 3.7 US
gal (14 liters, 3.1 Imp gal).
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light
illuminates. Engine misfires as a
result of an empty tank could cause
damage to the engine.&

It flashes if the vehicle is driven with tires
of differing diameters fitted on the wheels
or with an excessively low air pressure in
any of the tires.
CAUTION
Continuing to drive with the AWD
warning light flashing can damage
the powertrain. If the AWD warning
light starts to flash, promptly park in
a safe place and check whether the
tires have differing diameters and
whether any of the tires has an
excessively low inflation pressure.&

! Vehicle Dynamics Control warning
light (yellow)
CAUTION
The Vehicle Dynamics Control sys-
tem provides its ABS control
through the electrical circuit of the
ABS system. Accordingly, if the ABS
is inoperative, the Vehicle Dynamics
Control system becomes unable to
provide ABS control. As a result, the
Vehicle Dynamics Control system
also becomes inoperative, causing
the warning light to illuminate.
Though both the Vehicle Dynamics
Control and ABS systems are inop-
erative in this case, the ordinary
functions of the brake system are
still available. You will be safe while
driving with this condition, but drive
carefully and have your vehicle
checked at a SUBARU dealer as
soon as possible.NOTE.If the electrical circuit of the Vehicle
Dynamics Control system itself mal-
functions, the warning light only illumi-
nates. At this time, the ABS (Anti-lock
Brake System) remains fully opera-
tional. .
The warning light illuminates when
the electronic control system of the
ABS/Vehicle Dynamics Control system
malfunctions.
The Vehicle Dynamics Control system is
probably inoperative under any of the
following conditions. Have your vehicle
checked at a SUBARU dealer immedi-
ately.
. 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 below, the Vehicle Dynamics
Control system may be considered
normal.
. The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
. The warning light illuminates after
engine startup and turns off while the
vehicle is subsequently being driven.
. The warning light illuminates during
driving, but it turns off immediately and
