the charging system and batteries checked at an
authorized Freightliner service facility.
On a vehicle equipped with a battery isolator system,
the voltmeter measures the average voltage of all the
batteries when the engine is running. When the
engine is off, the voltmeter shows only the isolated
battery voltage and does not indicate the voltage of
the engine-starting batteries.
Overhead Instrument Panel
The overhead instrument panel, shown in Fig. 3.46,
may hold a citizen’s band (C/B) radio, a microphone
clip, and any switches that can not be
accommodated on the driver’s or auxiliary dash
panels.
The underside of the overhead console also holds
the sun visors and the optional dome/reading light
assembly. For more information on the dome/reading
light assembly, see
Chapter 4.

Warnings, Indicators, and Messages
Warning and indicator lights (telltales) with icon
symbols are displayed on the physical dashboard
and on ICU screens. The positions of the telltales
and warnings vary, but most telltale symbols are
standard. See the below tables for a listing of
different warnings and telltales in addition to
messages and popup screens.
The colors of telltales and warnings indicate the
hazard level: red (warning), amber (caution), green
and blue (active status), grey (passive status), white
(informational). Blue is currently used to indicate an
active phone call, that a software download is
available, and that utility lamps and high beams are
on.
IMPORTANT: Depending upon local
jurisdictional emissions guidelines, vehicles
and/or engines that are domiciled outside of the
U.S. and Canada may not be compliant with
EPA10 or GHG21 regulations. Noncompliant
vehicles may not be equipped with all of the
telltales shown in the below tables.
