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 262_F (128_C), the message HOT...IDLE ENGINE will appear. It means you should reduce the engine load and speed to prevent the engine from overheating. If the coolant temperature is over 268_F (131_C), the message HOT...STOP ENGINE will appear. It means that your engine coolant has overheated. You should pull off the road, stop your vehicle and turn off the engine as soon as possible. Your vehicle is equipped with an Overheated Engine Protection Operating Mode. See "Engine Overheating" in the Index for more information. 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 Driver Information Center (DIC). As the engine cools down, the air conditioning compressor will automatically turn back on. 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. 2-72
