This gage shows the engine coolant temperature.

It also provides an indicator of how hard your vehicle is working. During the majority of the operation, the gage will read 210°F (100°C) or less.

If you are pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 250°F (122°C) mark. When the gage reads greater than 250°F (122°C), the HOT COOLANT TEMP light will be illuminated in the message center and a chime will sound continuously. If the gage reaches the 260°F (125°C) mark, it indicates that the cooling system is working beyond its capacity.
