ignition is turned off. After the ignition turns
off, the engine aftertreatment system
circulates DEF to help cool down the fluid
and prevent overheating. For situations
where the battery will be disconnected (i.e.
for service or maintenance of the vehicle),
please wait 10 minutes before
disconnecting battery power.
CAUTION
Wait at least 10 minutes after the key
switch is turned OFF before discon-
necting battery power. The system
uses battery power to circulate DEF
and prevent overheating of the DEF
system. Failure to comply may result
in property damage.
Low Voltage Disconnect (LVD)
(option)
The Low Voltage Disconnect (LVD) may
increase battery life and avoid depleting
the battery below the minimum charge
needed to start the engine by shutting off
non-vital battery loads.
When battery voltage drops below the LVD
setting, LVD starts a two-minute
countdown. If battery voltage remains
below the LVD setting and the engine is
not started, when the countdown ends, all
non-vital battery loads (hotel loads) will be
shut off. The LVD setting is adjusted in the
Settings sub-menu of the Digital Display.
When battery voltage drops below the LVD
setting
1.
An amber LVD Popup notification
occurs, accompanied by an audible
warning. This starts the two-minute
countdown.
2.
Thirty seconds before the
countdown ends, the Battery
Voltage indicator is replaced by the
amber (or red) LVD telltale
21
. The
LVD popup notification will turn red
and will be accompanied by a
continuous audible warning.
3.
When the two-minute countdown
has ended, the LVD “Hotel Loads
Disconnected” Popup appears, and
LVD shuts off all loads connected
through the LVD system.
The LVD condition will not clear until
battery voltage increases above the LVD
setting or the engine is started.
Electrical loads shut off by LVD
•
Cab dome lamps
•
Cab accessories
•
Spare LVD wiring for customer
added accessories
WARNING
DO NOT use the Spare Battery A and
B circuits or other circuits that are con-
trolled by the LVD to power electronic
engine controls, ABS circuits, or safe-
ty/work related lighting. Before adding
any device to the vehicle's electrical
system, consult your nearest author-
ized dealer or read the contents of
TMC RP136. Failure to do so may
cause equipment damage or lead to
personal injury.

On the 15 inch display, LVD telltale color depends on the severity of battery depletion.
