Sleeper fan on
Optimized idle can be started with the engine running
or the engine off.
With the key on, go to Vehicle Settings and scroll
down to Optimized Idle. Press OK.
To enable optimized idle, press okay again. A screen
will appear saying the default battery mode is on and
interior comfort mode is off.
If you want to optimize the environment of the
sleeper section, turn on comfort mode. Press the
right hand arrow in the left hand switch pod to turn
interior comfort mode on and then press OK.
The vehicle will go into standby mode, an under
hood alarm will briefly sound, and the engine will
crank and achieve 900 rpm. The ICUC screen will
then state that it is in interior comfort mode and the
engine and air conditioning/fan will run until it
achieves the temperature requested by the driver.
The engine will then shut down.
Optimized idle can be shut off by ICUC controls or
pressing the brake. If the sleeper fan is turned off,
optimized idle will not shut down but the engine will.
For a fuller description of Optimized Idle, see Chap-
ter 13 Optional Engine Systems.
