CAUTION
Prolonged periods of idling can result
in lower than optimal engine/transmis-
sion operating temperatures which
could cause increased rates of wear.
Do not allow the engine to operate
at idle for extended periods at tem-
peratures at or below 160F/71C. To
help prevent this from occuring on
PACCAR engines, an idle shutdown
feature can be programmed to shut
the engine down after a period of low
idle operation with no driver activity. A
flashing warning lamp will inform the
driver of an impending shutdown. Fail-
ure to comply may result in equipment
or property damage.
NOTE
If you are required to idle your vehicle
for long periods of time, install an aux-
iliary heater or automatic idle control.
These auxiliary devices can reduce
fuel consumption and save you mon-
ey.
When active, the Shutdown Timer will keep
the engine running for a period of time after
the ignition switch is placed in the OFF
position. This allows the driver to exit the
cab while sustaining power to the cab
interior. Normally, this would require the
key to remain in the ignition, potentially
leaving the cab unlocked and accessible.
When the timer reaches zero, the engine
stops, removing power from certain
electrical loads. The timer counts down in
the Drive Summary.
The Shutdown Timer is enabled or
disabled in the Display menu and can be
set for up to 30 minutes. This setting can
be changed in the Settings Sub-menu or
while counting down, in the Drive
Summary, using the Scroll and Select (See
How to Set the Shutdown Timer on page
140). The Shutdown Timer setting may be
limited to less than 30 minutes (See
Greenhouse Gas Certified Configuration).
If your truck has the Engine Idle Shutdown
Timer (EIST) option and it is set for a
shorter shutdown time, the Engine will
shutdown at the shorter timer setting.
Driver Profiles
This feature saves customizations made as
a Driver Profile. Turning Driver Profiles ON
for the first time will load current
customizations into Driver Profile 1 and
make it the active profile. The profile can
be changed in this menu.
The active Driver Profile can also be
changed after setting the park brake and
then pressing Back.
2
Changes to Driver
Profile will be auto-saved while making
customizations. They will not be lost when
turning the feature off.
NOTE
The last used active profile, including
any changes to that profile, will remain
the profile until a new one is selected.
Choosing the Active Driver Profile
Press Back when the parking brake is set
to change the active Driver Profile.

The ignition key may need to be cycled back to OFF and then ON to access the Driver Profiles Settings.
