WARNING!

Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.

NORMAL OPERATION – DIESEL ENGINE

Observe the following when the engine is operating.

• All message center lights are off.
• Check Engine Lamp is off.
• Engine Oil Pressure is above 10 psi (69 kPa) at idle.
• Low Oil Pressure light is off.

• 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 mani-
fold heater system. The number of cycles and the
length of the cycling operation is controlled by the
engine control module. Post-heat operation can run
for several minutes, and then the electrical 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.
