NORMAL OPERATION
Observe the following when the diesel engine is operat-
ing.
•All message center lights are off.
•Malfunction Indicator Light (MIL) is off.
•Engine Oil Pressure telltale is not illuminated.
•Voltmeter operation:
The voltmeter may show a gauge fluctuation at various
engine temperatures. This is caused by the glow plug
heating system. The number of cycles and the length of
the cycling operation is controlled by the engine control
module. Glow plug heater operation can run for several
minutes, once the heater operation is complete the volt-
meter needle will stabilize.
Cold Weather Precautions
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts sug-
gest these options:
