This gage shows the engine coolant temperature. Under normal driving conditions the gage will read 210°F (100 °C) or less. If the gage pointer is near 260°F (125 °C), the engine is too hot.

It means that your engine coolant has overheated. If you have been operating your vehicle under normal driving conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible.
