Engine Idle Limiting
Idle Shutdown Timer
This feature is an optional 1- to 100-minute idle shut-
down system with a timer on the driver display
screen. Its purpose is to conserve fuel by eliminating
excessive idling, and allowing a turbocharger cool-
down period. Idle shutdown timing and parameters
are programmable. See the engine manufacturer’s
operation manual for specific details for your vehicle.
The idle shutdown system requires that the transmis-
sion be in neutral with the parking brake set.
California Engine Idle Limiting
In order to meet the California Air Resources Board
(CARB) engine idle limit, vehicles are equipped with
an engine idle shutdown feature. The automatic shut-
down feature is required on all California-certified
engines (with the exception of engines used in spe-
cific vehicle types that are exempt from the require-
ment). Owners that wish to have the shutdown fea-
ture disabled on vehicles operating in California
should consult with California authorities to determine
if their vehicle qualifies for the exemption.
When the CARB engine idle limiting feature is en-
abled, the engine will typically shut down after five
minutes of continuous idling with the transmission in
neutral or park, and the parking brake set. It will also
shut down after 15 minutes with the transmission in
neutral or park, and the parking brake off. See the
engine manufacturer’s operation manual for specific
details for your vehicle.
Changing the position of the brake pedal, clutch
pedal, accelerator pedal, shutdown override switch,
or parking brake during the final 30 seconds will
cause the shutdown timer to reset. After an auto-
matic shutdown, the engine may be restarted and
operated normally.
Optimized Idle®
Optimized Idle is an optional feature on vehicles
equipped with Detroit engines only. With the vehicle
parked, Optimized Idle reduces engine idle time by
running the engine only as required.
Optimized Idle automatically shuts down and restarts
the engine as needed to:
•
keep the engine oil temperature between pro-
scribed limits;
•
maintain battery voltage;
•
keep the cab and sleeper areas at the thermo-
stat setting; and
•
in coordination with ParkSmart (if equipped),
maintain the battery and assist in HVAC.
The benefits of the system include reduced engine
idle time, fuel savings, reduction of exhaust emis-
sions and noise, increased starter and engine life,
and reduced chance of dead batteries.
Optimized Idle operates in the following modes:
•
Cold startability and battery modes: Keeps the
battery charged and engine oil temperature
between proscribed limits.
•
Interior comfort mode (sleeper cabs without
ParkSmart only): Keeps the cab and sleeper at
a constant preset temperature, in addition to all
functions available in cold startability and bat-
tery modes. Extended and continuous run
modes allow the engine to keep running longer
if necessary.
•
Interior comfort mode with ParkSmart (sleeper
cabs with ParkSmart only): Keeps the cab and
sleeper at a constant preset temperature, in
addition to all functions available in cold start-
ability and battery modes.
In cold startability mode, Optimized Idle starts the
engine when engine oil temperature drops to 10°F
(–12°C). The engine is shut down when engine oil
temperature reaches 104°F (40°C), unless the re-
quirements of other active modes require the engine
to keep running.
Interior comfort mode controls the temperature set
point, which is the desired temperature of the cab
and sleeper, and the comfort zone, which is the al-
lowed temperature deviation from the set point be-
fore the engine starts.
On interior comfort mode, the engine runs for 2
hours before shutting down. On vehicles without
ParkSmart, the engine will run an additional 2 hours
in extended mode if necessary, and continuously in
continuous mode. When in continuous mode, the
driver display will indicate Optimized Idle status as
"continuous battery mode." Continuous mode may
indicate a problem, such as a bad battery.
In extreme ambient conditions, comfort mode may
stay on continuously.
NOTE: If the mode settings are changed while
in one mode, the system may continue running
in another mode.
