Fig. 1, Switch and Gauge Panels
The instrument cluster (ICU3-M2) is located right behind the steering wheel. No controls are installed on the standard instrument cluster.
The right-hand control panel (Fig.) usually contains 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 (Fig.) 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.
