198 INSTRUMENT PANEL AND CONTROLS NOTE: As the coolant temperature gauge approaches H, this indicator will illuminate and a single chime will sound. Further overheating will cause the temperature gauge to pass H. In this case, the indicator will flash continuously and a continuous chime will sound, until the engine is allowed to cool. WARNING! A hot engine cooling system is dangerous. You or others could be badly burned by steam or boiling coolant. You may want to call a service center if your vehicle overheats. If you decide to look under the hood yourself, see Section 7 of this manual. Follow the warnings under the Cooling System Pressure Cap paragraph. 23. Coolant Temperature Gauge The temperature gauge indicates engine coolant temperature. Any reading within the normal range indicates that the cooling system is operating satisfactorily. The gauge pointer will likely indicate a high temperature when driving in hot weather, up mountain grades, in heavy traffic, or when towing a trailer. If the pointer rises to the "H" mark, safely pull over and stop the vehicle. If CAUTION! Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads "H," pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on the "H," and you hear continuous chimes, turn the engine off immediately, and call for service.
