This gage shows the engine coolant temperature.

To prevent engine overheating, the air conditioning compressor will turn off automatically just prior to the gage pointer entering the shaded area. As the engine cools down, the air conditioning compressor will automatically turn back on. On vehicles equipped with the DIC, the message ENGINE HOT... A/C DISABLED will appear in the DIC display and a warning chime will sound.

If the gage pointer moves into the shaded area, your engine is too hot. On vehicles equipped with the systems monitor, the CHECK GAGES light will come on and a warning chime will sound.

On vehicles with a DIC, a CHECK GAGES TEMPERATURE message will be displayed and a warning chime will sound. See DIC Warnings and Messages for more information.

See Engine Overheating , for information on what to do if your engine overheats.
