Idle control:
•
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 and rain
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.
The following actions are recommended after operating the vehicle up to
200 miles (320 km) in snowfall or extreme rain:
•
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 foam
filter) and reset the air filter restriction gauge.
Note:
Removal of the foam filter degrades vehicle performance during
snow and hot weather conditions.
•
Extreme rain:
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.
Refer to
Air filter and restriction gauge
in the
Maintenance and
Specifications
chapter of this supplement for more information.
Operation in standing water
Ingestion of water into the diesel engine can result in immediate and
severe damage to the engine. If driving through water, slow down to
avoid splashing water into the intake. If the engine stalls, and ingestion
of water into the engine is suspected, do not try to restart the engine.
Consult your dealer for service immediately.
