„ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON” posi-
tion and goes out after approximately two seconds.
This is an indicati on that the ABS system
is working properly.
The ABS warning light comes on together
with the brake system wa rning light if the
EBD system becomes faulty. For further
details of the EBD system fault warning,
refer to “Brake syst em warning light”.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal. yThe warning light comes on right af- ter the engine is started but goes out
immediately, remaining off. y
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).y The warning light comes on 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 come
on. 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. „ Brake system
warning light
The tire pressure monitoring system
is NOT a substitu te for manually
checking tire pressure. The tire
pressure should be checked period-ically (at least mo nthly) using a tire
gauge. After any change to tire pres-sure(s), the tire pressure monitoring
system will not re-check tire infla-
tion pressures until the vehicle is
first driven more than 20 mph (32
km/h). Be sure to install the speci-
fied size for the front and rear tires.
If the warning light behaves as fol-
lows, the ABS system may not work
properly.
(U.S.) (Canada)
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally. y The warning light does not come
on when the ignition switch is
turned to the “ON” position.
y The warning light comes on when
the ignition switch is turned to the
“ON” position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12
km/h).
y The warning light comes on dur-
ing driving.
If any of these conditions occur,
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.
yDriving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.

„Door open warning light
When any of the doors or the rear gate
(Station wagon) or trunk lid (Sedan) is not
fully closed, it is indicated by the corre-
sponding part of the door warning light.
Always make sure this light is out before you start to drive. „ All-Wheel Drive warn-
ing light (AT vehicles)
The All-Wheel Drive warning light comes
on when the ignition switch is turned to the
“ON” position and goes out after the en-
gine has started. TFor 5-speed automatic transmission vehicles
This light flashes if the vehicle is driven
with tires of different diameters fitted on its
wheels or with the air pressure excessive-
ly low in any of its tires. T For 4-speed automatic transmission vehicles
This light comes on when All-Wheel Drive
is disengaged and the drive mechanism is
switched to Front Wheel Drive for mainte-
nance or similar purposes.
This light flashes if the vehicle is driven
with tires of different diameters fitted on its
wheels or with the air pressure excessive-
ly low in any of its tires. „ Vehicle Dynamics Con-
trol operation indicator
light (if equipped)
This light comes on when the ignition
switch is ON and goes out approximately
2 seconds later.
It blinks when the skid suppression func-
tion is activated. It illuminates when only
the traction control function is operating. The Vehicle Dynamics Control system is
probably faulty under any of the following
conditions. Have your vehicle checked at
a SUBARU dealer immediately. y
The light does not come on when the ig-
nition switch is turned to the “ON” position. y The light does not go out even after a
period of approximately 2 seconds after
the ignition switch has been turned to the
“ON” position. „ Vehicle Dynamics Con-
trol warning light (if
equipped)/Vehicle Dy-
namics Control OFF indicator
light (if equipped)
This warning light has both the function of
indicating faults in the Vehicle Dynamics
Control system and the function of indicat-
ing that the Vehicle Dynamics Control sys-
tem has been deactivated.
It comes on in the event of a fault in the
system and is on when the system is not
operating.
This warning light comes on when the ig-
nition switch is turned to the “ON” position
and goes out after the engine has started.
It indicates that the Vehicle Dynamics
Control system is in normal operation.
(Turbo model only) Promptly put
fuel in the tank whenever the low
fuel warning light comes on. Engine
misfires as a result of an empty tank
could cause damage to the engine.
Continued driving with the AWD
warning light flashing can lead to
powertrain damage. If the AWD
warning light flashes, promptly park
in a safe place then check whether
all four tires are the same diameter
and whether any of the tires has a
puncture or has lost air pressure for
some other reason.
