Voltmeter operation:
The voltmeter may show a gauge fluctuation at various
engine temperatures. This cycling operation is caused by
the post-heat cycle of the intake manifold heater system.
The number of cycles and the length of the cycling opera-
tion is controlled by the engine control module. Post-heat
operation can run for several minutes, and then the elec-
trical system and voltmeter needle will stabilize.
The cycling action will cause temporary dimming of the
headlamps, interior lamps, and also a noticeable reduction
in blower motor speed.
Cold Weather Precautions
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts sug-
gest these options:
