WHAT TO DO IN EMERGENCIES 351 NOTE: There are steps that you can take to slow down an impending overheat condition. If your air conditioner is on, turn it off. The air conditioning system adds heat to the engine cooling system and turning off the A/C removes this heat. You can also turn the Temperature control to maximum heat, the Mode control to floor, and the fan control to high. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system. CAUTION! Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads "H", pull over when safe and stop the vehicle with the engine at idle. Turn the air conditioner off and wait until the pointer drops back into the normal range. After appropriate action has been taken, if the pointer remains on the "H", turn the engine OFF immediately and call for service. 6
