Rear differential oil temperature warning light

CAUTION


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.

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.
