ing a shutdown. "When the actual ambient temperature falls outside
the specified indicator range.Warning and indicator lights
Several of the warning and indicator lights come on
momentarily and then go out when the ignition switch
is initially turned to the “ON” position. This permits
checking the operation of the bulbs.
Apply the parking brake and turn the ignition switch to
the “ON” position. The following lights come on:
Seatbelt warning light
SRS airbag system warning light
CHECK ENGINE warning light/Malfunction indica- tor lamp
Charge warning light
Oil pressure warning light
AT OIL temperature warning light (AT vehicles)ABS warning light
Brake system warning light
If any lights fail to come on, it indicates a burned-out
bulb or a malfunction of the corresponding system.
Consult your authorized SUBARU dealer for repair. ! Seatbelt warning light and chime
When the ignition switch is turned to the “ON” position,
the seatbelt warning light will come on and the remind-
er chime will sound for about six seconds to remind the

tires are not all the same size and brand, the rear
differential will be heavily loaded when the vehicle
is driven, resulting in an abnormally high oil tem-
perature. "The rear differential oil will deteriorate if its tem-
perature increases enough for the rear differential
oil temperature warning light to come on. It is ad-
visable to have the rear differential oil replaced as
soon as possible. ! ABS warning light
The ABS warning light comes on when the ignition
switch is turned to the “ON” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.
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 continues to operate normally." The warning light does not come on when the
ignition switch is turned to the “ON” position." 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)."
The warning light comes on during driving.
If these 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 comes on 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 be-
low, the ABS system may be considered normal." The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off." The warning light remains on after the engine
has been started, but it goes out when the vehicle
speed reaches about 8 mph (12 km/h)." 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 volt-
age and does not indicate a malfunction. When the
battery becomes fully charged, the light will go out. !
Brake system warning light
"Driving with the brake system warning light
on is dangerous. This indicates your brake sys-
tem may not be working properly. If the light re-
mains on, 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.
This light has the following two functions: ! Parking brake warning
The light comes on with the parking brake applied
while the ignition switch is in the “ON” position. It goes
out when the parking brake is fully released. !
Brake fluid level warning
This light comes on when the brake fluid level has
dropped to near the “MIN” level of the brake fluid res-
ervoir with the ignition switch in the “ON” position and
with the parking brake fully released.
If the brake system warning light should come on 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 near-
est safe place and check the brake fluid level. If the flu-
id level is below the “MIN” mark in the reservoir, do not
drive the vehicle. Have the vehicle towed to the near-
est SUBARU dealer for repair. ! Electronic Brake Force Distribution (EBD) sys-
tem warning (for vehicles with ABS)
The brake system warning light also illuminates if a
malfunction occurs in the EBD system. In that event, it
comes on 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 conventional 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 vehicle’s motion may there-

fore become somewhat 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, then restart it.
3. Release the parking brake. If both warning lights go
out, the EBD system may be faulty. Drive carefully to
the nearest SUBARU dealer and have the system in-
spected.
4. If both warning lights come on again and stay illu-
minated 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 faulty. Drive carefully to the
nearest SUBARU dealer and have the system inspect-
ed.
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. !Door open warning lights
The door open warning light comes on if any door or
the rear gate is not fully closed.
Always make sure this light is out before you start to drive. !
Front-wheel drive warning light
(for AT vehicles – if equipped)
This light comes on when All Wheel Drive is disen-
gaged and the drive mechanism is switched to Front
Wheel Drive for maintenance or similar purposes. ! Intercooler water spray warning
light (WRX-STi)
This light comes on when the water level in the inter-
cooler water spray tank falls to the lower limit (about
0.4 U.S. qt, 0.4 liter, 0.4 Imp qt.).

Starting and operating
ABS (Anti-lock Brake System)
The ABS system prevents the lock-up of wheels which
may occur during sudden braking or braking on slip-
pery road surfaces. This helps prevent the loss of
steering control and directional stability caused by
wheel lock-up.
When the ABS system is operating, you may hear a
chattering noise or feel a slight vibration in the brake
pedal. This is normal when the ABS operates.
The ABS system will not operate when the vehicle
speed is below approximately 6 mph (10 km/h).
Always use the utmost care in driving – over-
confidence because you are driving with an
ABS equipped vehicle could easily lead to a se-
rious accident.
"
The ABS system does not always decrease
stopping distance. You should always main-
tain a safe following distance from other vehi- cles. "
When driving on badly surfaced roads, gravel
roads, icy roads, or over deep newly fallen
snow, stopping distances may be longer for a
vehicle with the ABS system than one without.
When driving under these conditions, there-
fore, reduce your speed and leave ample dis-
tance from other vehicles. " When you feel the ABS system operating,
you should maintain constant brake pedal pres-
sure. Do not pump the brake pedal since doing
so may defeat the operation of the ABS system.
! ABS system self-check
You may feel a slight shock in the brake pedal and hear the operating sound of ABS from the engine com-
partment just after the vehicle is started. This is
caused by an automatic functional test of the ABS sys-
tem being carried out and does not indicate any abnor-
mal condition.
