WHAT TO DO IN EMERGENCIES 385 CAUTION! Driving with a hot cooling system could damage your vehicle. If the pointer rises to the H (red) mark, the instrument cluster will sound a chime. When safe, pull over and stop the vehicle with the engine at idle. Turn off the air conditioning and wait until the pointer drops back into the normal range. If the pointer remains on the H (red) mark for more than a minute, turn the engine off immediately and call for service. WARNING! You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you see or hear steam coming from under the hood, do not open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator or coolant bottle is hot. AUTOMATIC TRANSAXLE OVERHEATING During sustained high speed driving or trailer towing up long grades on hot days, the automatic transaxle oil may become too hot. If this happens, the transmission overheat indicator light will come on, and the vehicle will slow slightly until the automatic transaxle cools down enough to allow a return to the requested speed. If the high speed is maintained, the overheating will reoccur, as before, in a cyclic fashion. 6
