Cold Weather Operation (6.8L V10 Gasoline)
To avoid engine fuel starvation during cold weather operation of 32°F (0°C) or below, the manufacturer recommends
that the fuel level in your tank should not drop below 1⁄4 full. is helps prevent air from entering the fuel system
and stalling the engine.
If you operate your vehicle in a heavy snowstorm or blowing snow conditions, snow and ice can clog the engine
air induction. If this occurs, the engine may experience a signicant reduction in power output. At the earliest
opportunity, clear all the snow and/or ice away from inside the air lter assembly. Remove the air cleaner cover
and the pleated paper lter, leaving the foam lter in and remove any snow or ice. Make sure you install the foam
lter correctly in place. Remove any debris, snow or ice on the foam lter by brushing the surface with a so brush.
Once you have cleared all of the debris, reinstall the air lter and assembly.
Note: Do not use water, solvents, or hard brushes to clean the air lter.
Warning: To reduce the risk of vehicle damage and/or personal burn injuries do not start your engine with the
air lter removed and do not remove it while the engine is running.
