Activating Optimized Idle
The vehicle must be in neutral gear, the hood
latched, and the park brake set for Optimized Idle to
work. Failure to meet these conditions result in a
checklist pop-up screen showing both the met and
unmet conditions. See
Fig 10.1.
Dismiss the pop-up screen, fix the issue(s), and
restart Optimized Idle.
NOTE: Turning the sleeper HVAC fan off turns
off the interior comfort mode until the fan is
turned back on.
1.
Set the parking brake.
2.
If open, close and secure the hood.
3.
Allow the engine to idle if it is running. If the
engine is not running, turn the key to the ON
position.
4.
Put the transmission in neutral.
5.
Navigate to the Optimized Idle screen on the
driver display. See Fig. 10.2.
6.
Press OK on the steering wheel switch pod to
view the mode option screen. See Fig. 10.3.
7.
Select OK to enable Optimized Idle, and, if
desired, turn on the interior comfort mode
(sleeper cabs only). The current Optimized Idle
state is displayed. See
Fig. 10.4.
When Optimized Idle is active, the Optimized Idle
telltale illuminates at the bottom of the driver
display. See
Fig. 10.5.
If Optimized Idle fails to start, see the driver
display for information.
8.
If the interior comfort mode is activated (sleeper
cabs only), set the desired temperature and fan
speed on the sleeper HVAC controls.
The allowable temperature range for Optimized
Idle operation is 65 to 80°F (18 to 27°C).
