Stopping the Engine Move the shift lever to P (Park) and press the Acc. button located on the instrument panel. If the shifter is not in P (Park), the engine shuts off and the vehicle goes into the Accessory Mode. The DIC displays SHIFT TO PARK. Once the shifter is moved to P (Park), the vehicle turns off. The DIC displays NO FOB, OFF OR RUN?, if the keyless access transmitter is not detected inside the vehicle when it is turned off. See DIC Warnings and Messages on page 3-79 for more information. To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. For the 3.6L V6 and 4.4L V8 engine, the cord is located in the front of the engine compartment, on the passenger side of the vehicle. For the 4.6L V8 engine, the cord is located in the engine compartment on the driver side of the vehicle near the inner fender and above the strut. 3. You must remove the plastic cap to access the plug. 4. Plug it into a normal, grounded 110-volt AC outlet. Engine Coolant Heater The engine coolant heater can provide easier starting and better fuel economy during engine warm-up in cold weather conditions at or below 0°F (−18°C). Vehicles with an engine coolant heater should be plugged in at least four hours before starting. Some models have an internal thermostat in the cord which will prevent engine coolant heater operation at temperatures above 0°F (−18°C). { CAUTION: Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord will not reach, use a heavy-duty three-prong extension cord rated for at least 15 amps. 2-29
