yellowblue Engine Coolant Temperature Gage This gage shows the engine coolant temperature. If the gage pointer moves into the red warning zone, your engine is hot. If the coolant temperature is over 261_F (127_C), the message HOT...STOP ENGINE will appear. 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. The "Problems on the Road" section in this manual explains what to do. See "Engine Overheating" in the Index. If your coolant level is low, the message LOW ENGINE COOLANT will appear on the Driver Information Center. Check your coolant level as soon as possible. See "Engine Coolant" in the Index. To prevent engine overheating, the air conditioning compressor will turn off automatically, a fast-pulsed chime will sound, and the message ENGINE HOT...A/C OFF will appear in the information center. As the engine cools down, the air conditioning compressor will automatically turn back on. 2-70
