Abs Warning Light - Subaru 2008 Impreza Owner's Manual

3-22
Instruments and controls
illuminates steadily after blinking for
approximately one minute, promptly
contact a SUBARU dealer to have
the system inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low
pressure threshold, the low tire
pressure warning light should go
off a few minutes later. Therefore, be
sure to install the specified size for
the front and rear tires.

ABS warning light

The ABS warning light illuminates when
the ignition switch is turned to the "ON"
position and turns off after approximately 2
seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, the ABS system may not
work properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally.
The warning light does not illu-
minate 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 go out even when the
vehicle speed exceeds approxi-
mately 8 mph (12 km/h).
The warning light illuminates dur-
ing driving.
If any of these conditions occur,
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.
With a vehicle equipped with an EBD
system, the ABS warning light illuminates
together with the brake system warning
light if the EBD system becomes faulty.
For further details of the EBD system fault
warning, refer to "Brake system warning
light".
NOTE
If the warning light behavior is as
described in the following, the ABS
system may be considered normal.
The warning light illuminates right
after the engine is started but goes out
immediately, remaining off.
The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).
The warning light illuminates during
driving, but it goes out 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 go out.
