CAUTION
The fan or equipment near it could be
damaged if the fan turns on suddenly
when you do not expect it. Keep all
tools and equipment away from the
fan.
Using a Winterfront
CAUTION
The use of a winterfront can result in
excessive coolant, engine oil, and in-
take air temperatures, which may lead
to overheating and possible engine
damage.
CAUTION
A winterfront should only be used at
temperatures below 40°F (4°C). Use
of a winterfront above 40°F (4°C) can
decrease life of cooling module com-
ponents. Remove winterfront as soon
as the ambient temp reaches 41°F
(5°C). The use of a winterfront above
40°F (4°C) can result in excessive
coolant, engine oil, and intake air tem-
peratures, which may lead to over-
heating and possible engine or coolant
module damage and emissions non-
compliance.
The winterfront is designed to minimize the
temperature differences across the radiator
and reduce the possibility of cooling
module damage. Aftermarket winterfronts
may not provide the proper airflow
distribution and could cause cooling
module damage.
How to Set the Shutdown Timer
The Shut Down Timer must first be
enabled. Enabling the shutdown timer is
located in the Settings Sub-menu.
Follow these steps to turn on the engine
idle shutdown timer. The shutdown timer
will default to 5 minutes (or the last value
used) and can be set up to 30 minutes
unless limited by the Engine Shutdown
System (Clean Idle on page 314)
WARNING
Never idle your vehicle for prolonged
periods of time if you sense that ex-
haust fumes are entering the cab. In-
vestigate the cause of the fumes and
correct it as soon as possible. If the
vehicle must be driven under these
conditions, drive only with the windows
open. Failure to repair the source of
the exhaust fumes may result in death,
personal injury, equipment or property
damage.
CAUTION
DO NOT idle the engine for excessive-
ly long periods. Long periods of idling,
more than 10 minutes, can cause poor
engine performance.
1. Using the
Scroll Wheel, target the
number of minutes and press
Select.
2. Back to return to the Settings
menu.
