Instrument and Control Panel
Figure 3.1 represents a typical dash equipped with all
of the standard and many of the optional instruments
and controls.
Warning and indicator light modules, located on each
side of the speedometer, house all of the standard and
optional warning and indicator lights. Figure 3.2 identi-
fies the warning and indicator lights.
Controls
Ignition Switch and Key
The ignition switch can be turned to four positions: OFF,
ACCESSORY, ON, and START. See Fig. 3.3. The igni-
tion switch key also locks and unlocks the cab doors.
The key can be inserted and removed only from the
OFF position. The headlights (low beam only), brake
lights, fog lights, dome lights, clearance lights, turn sig-
nals, hazard warning lights, parking lights, and the cigar
lighter operate with the ignition switch off, regardless of
whether the key is inserted.
In the ACCESSORY position, the wipers, heated mir-
rors, backup lamps, radio, ether start system, and all
electric gauges operate.
Turn the key fully clockwise to the START position, only
when starting the engine. When the engine starts, re-
lease the key. When released, the key will move to the
ON position.
In the ON position, all electrical systems are operable.
Warning lights and buzzer for low air pressure and low
oil pressure operate until the engine is started and mini-
mum pressures are built up.
Panel Light Control
The panel lights (see Fig. 3.4) are turned on by the
headlight switch. The panel light control lever adjusts
the brightness of the instrument panel lights. Slide the
control lever up to brighten the lights, and down to dim
them. Move the control lever all the way down to turn
them off.
Headlight Switch and Daytime
Running Lights
In the up position all of the lights are off. See Fig. 3.5.
Turning the switch clockwise one position turns on the
marker/clearance lights, taillights, parking lights, license
plate light, and panel lights. Turning the switch clock-
wise another position turns on the headlights, marker/
clearance lights, taillights, parking lights, license plate
light, and panel lights.
