WHAT TO DO IN EMERGENCIES 261 CAUTION! Driving with a hot cooling system could damage your vehicle. If the pointer of the Coolant Temperature Gage rises to the H (red) mark, the instrument cluster will sound a chime. When safe, pull over and stop the vehicle. 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. NOTE: There are steps that you can take to slow down an impending overheat condition: • If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat. • You can also turn the temperature control to maximum heat, the mode control to floor and the blower 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. 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, refer to "Cooling System Pressure Cap" in "Maintaining Your Vehicle" and follow the warnings under the paragraph. 6
