to maintain normal system voltage by auto-
matically increasing engine idle speed. You
may notice several consecutive increases in
idle speed, up to a maximum of 1450 RPM,
as the system will attempt to utilize the
smallest increase in idle speed necessary to
maintain normal system voltage. The idle
speed will return to normal when either the
electrical load is removed, or when the brake
pedal is applied.
NOTE:
For instrument cluster display messages re-
lated to the vehicle's exhaust system, refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further in-
formation.
Idle-Up Feature — Automatic Transmission
Only
The driver-controlled high idle speed feature
will help increase cylinder temperatures and
provide additional cab heat, however, exces-
sive idling may still cause the exhaust after-
treatment system to not properly regenerate.
Extended periods of idle time should be
avoided.
The Idle-Up feature uses the speed control
switches to increase engine idle speed and
quickly warm the vehicle's interior.
1. With the transmission in PARK, the park-
ing brake applied, and the engine run-
ning, push the speed control switch to the
ON position, then push the SET switch.
2. The engine RPM will go up to 1100 RPM.
To increase the RPM, push and hold the
ACCEL/RESUME switch and the idle
speed will increase to approximately
1500 RPM. To decrease the RPM, push
and hold the DECEL switch and the idle
speed will decrease to approximately
1100 RPM.
3. To cancel the Idle–Up feature, either push
the CANCEL switch, push the ON/OFF
switch, or press the brake pedal.
Stopping The Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricat-
ing oil and coolant to carry excess heat away
from the combustion chamber, bearings, in-
ternal components, and turbocharger. This is
especially
important
for
turbocharged,
charge air-cooled engines.
NOTE:
• During engine shut down on vehicles
equipped with manual transmissions, it is
normal for the diesel engine to resonate
heavily for a moment during engine shut
off. When the engine is connected to a
manual
transmission,
this
resonance
causes load gear rattle from the transmis-
sion. This is commonly referred to as “shut
down rattle.” The manufacturer recom-
mends performing engine shut down with
the clutch pedal pushed to the floor (clutch
disengaged). When engine shut down is
performed in this manner the rattle is re-
duced (not eliminated).
• Refer to the following chart for proper en-
gine shutdown.
