Driving Do not use starting fluid such as ether in the air intake system. Such fluid could cause immediate explosive damage to the engine and possible personal injury. If you should experience cold weather starting problems on E85 ethanol, and neither an alternative brand of E85 ethanol nor an engine block heater is available, the addition of unleaded gasoline to your tank will improve cold starting performance. Your vehicle is designed to operate on E85 ethanol alone, unleaded gasoline alone, or any mixture of the two. See Choosing the right fuel in the Maintenance and Specifications chapter for more information on ethanol. If the engine fails to start using the preceding instructions (flexible fuel vehicles only) 1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then crank the engine. 2. When the engine starts, release the key, then gradually release the accelerator pedal as the engine speeds up. If the engine still fails to start, repeat Step 1. Guarding against exhaust fumes Carbon monoxide is present in exhaust fumes. Take precautions to avoid its dangerous effects. WARNING: If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Important ventilating information If the engine is idling while the vehicle is stopped for a long period of time, open the windows at least 1 inch (2.5 cm) or adjust the heating or air conditioning to bring in fresh air. ENGINE BLOCK HEATER (IF EQUIPPED) An engine block heater warms the engine coolant which aids in starting and allows the heater/defroster system to respond quickly. If your vehicle is equipped with this system, your equipment includes a heater element which is installed in your engine block and a wire harness which allows the user to connect the system to a grounded 120 volt A/C electrical source. The block heater system is most effective when outdoor temperatures reach below 0°F (-18°C). 211 2010 Mariner (mrn) Owners Guide, 1st Printing USA (fus)
