Differential Temperature
This is a a Rear Differential Temperature Indicator symbol. If this light is on while the engine is running, it indicates that the oil in the rear differential is too hot. If you are driving, reduce your speed and stop at the nearest safe place. Allow the differential to cool down and the light to go out. The vehicle will then be safe to drive.
- Before continuing, are you sure this is your symbol?? If yes, then read on below.
- Otherwise you can return to our main Text Symbols page and scan again!
If the light recurs, stop again and allow time again for the differential to cool down. If overheating continues to occur or if the light does not go out at all, call your dealer, service center or roadside service for assistance.
