Notice: Holding the button in for longer than 15 seconds at a time will cause the vehicle's battery to be drained much sooner. This can also cause damage to the starter motor. Wait 15 seconds between each try to avoid draining your vehicle's battery or damaging the starter. 2. If the engine does not start and no DIC message is displayed, wait 15 seconds before trying again. Notice: Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you do not, your engine might not perform properly. Engine Coolant Heater Your vehicle may be equipped with an engine coolant heater. In very cold weather, 0°F (−18°C) or colder, the engine coolant heater can help. You will get easier starting and better fuel economy during engine warm-up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle. At temperatures above 32°F (0°C), use of the coolant heater is not required. To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The cord is located in the engine compartment on the driver's side of the vehicle near the engine oil dipstick. See Engine Compartment Overview on page 5-12 for more information on location. You must remove the plastic cap to access the plug. Stopping Your Engine Move the shift lever to PARK (P) and press the OFF/ACCESSORY button. If the shifter is not in PARK (P), the vehicle will go into accessory mode and the DIC will display SHIFT TO PARK. Once the shifter is moved to PARK (P), the vehicle will turn off. If the keyless access transmitter is not detected while going to off, the DIC will display NO FOB - OFF OR RUN?. See DIC Warnings and Messages on page 3-74 for more information. 2-25
