If the water in fuel indicator illuminates when the engine is running, stop your vehicle as soon as safely possible, shut off the engine, then drain the fuel and water separator.   See   Fuel Quality - E85.  Allowing water to stay in the fuel system, after the water in fuel indicator illuminates, could result in extensive damage or failure of the fuel injection system.
Note:   Do not drain the fuel and water separator while the engine is running. Air will enter into the fuel system causing the engine not to operate properly.
