headlight, panel light increase/decrease, and the
cruise control On/Off and Set/Resume switches.
The instrument cluster (ICU3-M2) is located right be-
hind the steering wheel. No controls are installed on
the standard instrument cluster.
The right-hand control panel (
) usually con-
tains the transmission push-button shift selector (on
vehicles with automatic or automated transmission)
and the trailer brake lever (hand control valve). On
vehicles with manual transmission, a variety of
switches are installed here. If there is a dash-
mounted air-restriction indicator, it is often mounted
here.
The radio panel contains two louvered dash outlets
for the face vents of the HVAC, one on either side of
the radio (if installed).
The auxiliary dash panel (
) below the radio
panel contains the marker interrupt switch, the air
brake valve knobs, the cigarette lighter, and a variety
of switch options.
The HVAC climate control panel is on a separate
panel below the auxiliary dash panel, between the
two cupholders.
Exterior Light Controls
Headlight/Parking Light Switch
The headlight/parking light switch (
) is a
paddle switch located on the left-hand control panel
above the cruise control switches. When the paddle
is lowered, the parking lights illuminate (the front turn
signals, the cab marker and identification lights, and
the taillights). When the paddle is raised, the low-
beam headlights illuminate, along with all the parking
lights. To turn off all lights, return the paddle to the
center position.
NOTE: The front turn signal is the amber lens in
each headlight unit. The low-beam headlight is
the top clear lens in each headlight unit.
When the headlights or parking lights are on, the
panel lights also illuminate. An amber light in the
switch backlights either the top icon (for headlights
and parking lights) or the bottom icon (for parking
lights only).
Panel Light Increase/Decrease Switch
When the panel lights are on, they can be either
brightened or dimmed by using the INCR/DECR
rocker switch just below the headlight switch
(
). To brighten the panel lights, press on the
upper part of the rocker (at the INCR legend). To dim
the panel lights, press on the lower part of the rocker
(at the DECR legend).
When the panel lights are on, both legends are back-
lit in green.
