restart, the fuel filter(s) may be clogged. For best results in cold
weather, use a diesel fuel which has been formulated for the ambient
conditions. If you have been using biodiesel, you may need to use a fuel
with lower biodiesel content, try another brand, or discontinue using
biodiesel.
Your vehicle is equipped with a diesel fuel conditioner module (DFCM)
which recirculates fuel from the engine to help prevent fuel filter
clogging. Your vehicle is also equipped with a bypass relief valve, located
in the fuel tank pick-up boot, which provides fuel flow to the engine if
the fuel pickup should become plugged. To allow the bypass valve to
function and avoid engine fuel starvation during cold weather operation
of 32°F (0°C) or below, it is recommended that the fuel level in your
tank should not be allowed to drop below
1 4full. This will help prevent
air from entering the fuel system and stalling the engine.
Your vehicle is equipped with a an SCR system which uses diesel exhaust
fluid (DEF) to operate properly. DEF must be replenished at certain
intervals. When filling the vehicle’s DEF tank in cold weather, special
care must be taken to prevent damage to the DEF tank. For proper cold
weather fill procedure, seeSelective Catalytic Reduction (SCR) System
in theMaintenance and Specificationschapter.
In cold weather below 32°F (0°C), the engine will slowly increase to a
higher idle speed if left idling in P (Park). As the engine warms-up, the
engine sound level will decrease due to the activation of PCM-controlled
sound reduction features.
If your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. If this occurs, the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all the snow
and/or ice away from inside the air filter assembly. Remove the air
cleaner cover and the pleated paper filter, leaving the foam filter in and
remove any snow or ice. Ensure the foam filter is installed correctly in
place. Remove any debris, snow and/or ice on the foam filter by brushing
the surface with soft brush. Do not use water, solvents, or a hard brush
for cleaning the foam filter.
In order to operate the engine in temperatures of 32°F (0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they are in
optimum condition.
•Use the proper coolant solution at the concentration recommended to
protect the engine against damage from freezing.
