Note:  Western Star vehicles are offered with various chassis and body components. Because of the various options, the information contained in this chapter may not apply to every vehicle.

The right-hand dash control panel contains a face vent, the majority of the driver switch controls, automated and automatic transmission controls, and the DataStar display module, if equipped. If there is a dash-mounted air intake restriction indicator, it is often mounted on the right-hand panel as well.

The ignition switch control panel (below the right-hand dash panel) contains the ignition switch, cigarette lighter, and climate controls.

The lightbar and instrument gauges are located behind the steering wheel.

Note:  Control locations may vary from those shown depending on vehicle options.
