ABS Warning Light
The 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 Light
This 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 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.
CAUTION
 If any of the following conditions
occur, we recommend that you
have the ABS 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 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.
