Idle control:
For periods of extended idle, the throttle should be set at an rpm that is
sufficient to keep the engine at normal operating temperatures. This
action can reduce the amount of engine damaging deposits.
•
The engine contains a unique “Cold Weather - Idle up feature”
calibration strategy within the PCM. Under the appropriate conditions,
the strategy will automatically elevate the engine idle speed after
130 seconds of idling in cold ambient temperatures. For this feature to
be activated, the truck must be in P (Park) (for automatic
transmission), in neutral (for manual transmission) with the parking
brake applied and engine oil temperature below 158°F (70°C). This
strategy raises the rpm to a level that reduces the potential to
produce “coking” or “wet stacking”, which is common to all diesel
engines when idling for extended periods during cold ambient
temperatures.
•
Your vehicle may have a factory option for a Stationary Elevated Idle
Control (SEIC) through dash-mounted Upfitter switches will allow the
operator to elevate the idle rpm for extended idle periods, as well as
aftermarket equipment such as PTO operation. This feature must be
configured even if ordered from the factory. See your authorized
dealer for required upfitting.
Operation in snow
Vehicle operation in heavy snowfall or extreme rain conditions may feed
excessive amounts of snow/water into the air intake system. This could
plug/soak the air filter with snow and may cause the engine to lose
power and possibly shut down.
You may not need to change the air filter and the vehicle may be driven
up to 200 miles (320 km) under the following conditions:
•
Snow:
At the earliest opportunity, open the hood and clear all the
snow and ice from the air filter housing inlet (do NOT remove the air
filter) and reset the air filter restriction gauge.
•
Wet:
The air filter will dry after about 15–30 minutes at highway
speeds. At the earliest opportunity, open the hood and reset the air
filter restriction gauge.
