Instruments and controls/Warning and indicator lights

The CHECK ENGINE warning light may
stop blinking and illuminate steadily after
several driving trips. You should have your
vehicle checked by an authorized
SUBARU dealer immediately.

& Charge warning light
If this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off 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 illuminated,
contact your nearest SUBARU dealer
immediately.

& Oil pressure warning
light

If this light illuminates 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 illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil is
at the proper level but the light remains

illuminated, contact your nearest
SUBARU dealer immediately.
For details about checking the engine oil
level or adding the engine oil, refer to
“Engine oil” F11-8.

CAUTION
Do not operate the engine with the
oil pressure warning light illuminated. This may cause serious engine damage.

& Rear differential oil

temperature warning
light (STI)
CAUTION

If the R.DIFF TEMP warning light
illuminates, reduce vehicle speed
and stop the vehicle in a safe
location as soon as possible. Continuing to drive with this light illuminated may damage the rear differential and other parts of the powertrain.
If this light illuminates 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 ratio setting and
adopt its minimum ratio.
If the light illuminates while driving, reduce
vehicle speed and stop the vehicle in the
nearest safe location. Park the vehicle for
several minutes. After the light turns off,
you can start driving.
If the light does not turn off, contact the
nearest SUBARU dealer for service.

NOTE
. 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 temperature.
. The rear differential oil will deteriorate if its temperature increases enough for the rear differential oil temperature warning light to illuminate. It is
advisable to have the rear differential
oil replaced as soon as possible.

& Low tire pressure

warning light (U.S.-spec.
models)

When the ignition switch is turned to the
“ON” position, the low tire pressure warning light will illuminate for approximately 2
