condition has been detected which may damage the
emission control system.
To prevent serious damage to the emission control
system, you should do the following:
yReduce vehicle speed.
y Avoid hard acceleration.
y Avoid steep uphill grades.
y Reduce the amount of cargo, if possible.
y Stop towing a trailer as soon as possible.
The CHECK ENGINE warning light may stop blinking
and come on steadily after several driving trips. You
should have your vehicle checked by an authorized
SUBARU dealer immediately. „ Charge warning light
If this light comes on when the engine is running, it
may indicate that the charging system is not working
properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the alternator belt. If the belt is
loose, broken or if the belt is in good condition but the
light remains on, contact your nearest SUBARU deal-
er immediately. „
Oil pressure warning light
If this light comes on when the engine is running, it
may indicate that the engine oil pressure is low and the
lubricating system is not working properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the engine oil level. If the oil lev-
el is low, add oil immediately. If the engine oil is at the
proper level but the light remains on, contact your
nearest SUBARU dealer immediately.
Do not operate the engine with the oil pressure
warning light on. This may cause serious en-
gine damage.
„ AT OIL TEMPerature warning
light (for AT vehicles)
The AT oil temperature warning light comes on when
the ignition switch is turned to the “ON” position and
goes out after about two seconds.
If this light comes on when the engine is running, it
may indicate that the automatic transmission fluid tem-
perature is too hot.

If the light comes on while driving, it is unnecessary to
stop the vehicle, but avoid driving up steep grades or
in stop and go traffic. TAutomatic transmission control system warn- ing
If the light flashes after the engine starts, it may indi-cate that the automatic transmission control system is
not working properly. Contact your nearest SUBARU
dealer for service immediately. „ Rear differential oil temperature
warning light (WRX-STi)
Reduce vehicle speed and park the vehicle in a
safe place as soon as possible if the R.DIFF
TEMP light comes on. Continued driving with
this light on can damage the rear differential
and other parts of the powertrain.
If this light comes on when the engine is running, it
may indicate that the rear differential oil temperature is
too hot.
At this time, the driver’s control center differential will automatically cancel the current torque-distribution ra-
tio setting and adopts its minimum ratio.
If the light comes on while driving, reduce vehicle
speed and stop the vehicle at the nearest safe place.
Park the vehicle for several minutes. After the light
goes out, you can start driving.
If the light does not go out, contact the nearest
SUBARU dealer for service.
NOTE y
If the tire pressures are not correct and/or 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.y 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.

SUBARU dealer for repair.
This light has the following three functions: T 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. T 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. T 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.
