Rear differential oil temperature warning light (STI)

Reduce vehicle speed and park the vehicle in a safe place as soon as possible if the R.DIFF TEMP light illuminates. Continued driving with this light illuminated can damage the rear differential and other parts of the powertrain.

Reduce vehicle speed and park the vehicle in a safe place as soon as possible if the R.DIFF TEMP light illuminates. Continued driving with this light illuminated can 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 drivers 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 at the nearest safe place. 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.
