seconds and then back ON. Repeat steps 1 through 5 of

Starting Procedure — Engine Manifold Air
Temperature Below 0°F (-18°C)

In extremely cold weather below 0°F (-18°C) it may be

beneficial to cycle the manifold heaters twice before

attempting to start the engine. This can be accomplished

by turning the ignition OFF for at least five seconds and

then back ON after the “Wait To Start” telltale has turned

off, but before the engine is started. However, excessive

cycling of the manifold heaters will result in damage to

the heater elements or reduced battery voltage.
NOTE:If multiple pre-heat cycles are used before start-
ing, additional engine run time may be required to
maintain battery state of charge at a satisfactory level.

1. If the engine stalls after the initial start, the ignition

must be turned to the OFF position for at least five

seconds and then to the ON position to recycle the

manifold heaters.

NOTE:

Excessive white smoke and poor engine perfor-

mance will result if manifold heaters are not recycled.
2. Heat generated by the manifold heaters dissipates

rapidly in a cold engine. If more than two minutes

pass between the time the “Wait To Start” telltale turns

off and the engine is started, recycle the manifold

heaters by turning the ignition switch to the OFF

position for at least five seconds and then back ON.

3. If the vehicle is driven and vehicle speed exceeds

19 mph (31 km/h) before the manifold heater post-

heat (after start) cycle is complete, the manifold heat-

ers will shut off.
