2017 SUBARU LEGACY check engine

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 turn
off a few minutes later. Therefore, be
sure to install the specified size for
the front and rear tires.
&ABS warning light
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 not 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 oper-
ate normally.
The ABS warning light illuminates to-
gether with the brake system warning light
if the EBD system malfunctions. For
further details of the EBD system mal-
function warning, refer to “Brake system
warning light ”F 3-19.
NOTE
If 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 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.
. If the brake system warning light
illuminates, the electronic park-

ing brake system may be mal-
functioning. Immediately stop
your vehicle in a safe location,
use tire stops under the tires to
prevent the vehicle from moving
and contact your SUBARU deal-
er. For details, refer to“Electro-
nic parking brake ”F 7-43.
NOTE
. Even if the brake system warning
light illuminates, if the warning light
behavior is as described in the follow-
ing examples, the electronic parking
brake system is not malfunctioning.
–The warning light turns off when
the electronic parking brake is ap-
plied or released.
– The warning light turns off when
the ignition switch is turned to the
“ ON ”position again.
. The brake system warning light may
illuminate immediately after the engine
is started. However, it is not malfunc-
tioning if the warning light turns off
after the electronic parking brake is
released.
. The brake system warning light may
illuminate after the electronic parking
brake is frequently applied and re-
leased. However, the electronic parking brake system is not malfunctioning if
the light turns off after a short period of
time.
.
When the engine is started while the
electronic parking brake is applied/
released, the system may judge an
abnormal situation and the warning
light may illuminate. If the warning light
illuminates, turn the ignition switch
once to the “LOCK ”/“ OFF ”position
and then restart the engine. Then,
apply/release the electronic parking
brake. If the warning light turns off,
the system will be restored.
This light has the following functions.
! 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 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
3-20

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.
! Electronic parking brake system
warning
The brake system warning light illumi-
nates when the electronic parking brake
system is malfunctioning. If the warning
light illuminates, promptly park in a safe
location as soon as possible and contact

tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steering
wheel is not operated for a while and
the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes power
assist limitation to occur too fre-
quently, that may result in a malfunc-
tion of the power steering control
system.
&Vehicle Dynamics
