Instruments and Controls Identification Instrument and Control Panel Controls Ignition Switch and Key Figure 2.1 , Figure 2.2 , and Figure 2.3 represent a portion of a typical Freightliner dash equipped with all of the standard and many of the optional instruments and accessories. Most standard and optional instru- ment gauges and switches can be mounted in this dash. The ignition switch ( Fig. 2.4 ) can be turned to three positions: "Off," "Accessory," and "On." In addition, the same key locks and unlocks the cab doors, bag- gage door(s), and, if equipped, the bunk door(s). In the "Off" position, the key slot is vertical; the key can be inserted and removed only in this position.
The low beam headlights, taillights, brake lights, fog lights, dome lights, clearance lights, turn signals, hazard warning lights, utility and baggage lights, spotlights, electric wipers, horn, CB radio, power mir- rors, cigarette lighter, clock, refrigerator, fuel heater, electric oil pan heater, and electric or diesel-fired engine-coolant preheaters can be operated in the off position (regardless of whether the key is inserted or not). NOTE: On SilverAero models, switches for cruise control and manual control for the engine fan are standard. If these features are not re- quested, dummy switches with blank labels are installed.
A warning and indicator light module, located above the speedometer and tachometer, houses all of the standard and optional warning and indicator lights. Some of the controls discussed in this chapter are not dash-mounted. In the "Accessory" position, the key is turned coun- terclockwise.
