To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The electrical cord is located on the driver's side of the engine compartment. 3. Plug it into a normal, grounded 1IO-volt AC outlet. How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer in the area where you'll be parking your vehicle. The dealer can give you the best advice for that particular area. Automatic Transaxle Operation Plugging the cord into an unground 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 won't reach, use a heavy-duty three-prong extension cord rated for at least 15 amps. 4. Beforestartingthe engine, be sureto unplug and store the cord as it was before to keep it away from moving engine parts. If you don't, it could be damaged.
