NOTE:
The temperature displayed in the instrument
cluster does not necessarily reflect the engine
manifold air temperature Ú page 90. When
engine temperatures fall below 66°F (19°C)
the "Wait To Start" telltale will remain on indi-
cating the intake air heater system is active.
Follow the steps in the "Normal Starting"
procedure except:
1. The "Wait to Start" telltale will remain on
for a period of time that varies depending
on the engine temperature.
2. While the "Wait to Start" telltale is on, the
instrument cluster will additionally display a
gauge or bar whose initial length represents
the full "Wait to Start" time period. Its length
will decrease until it disappears when the
"Wait to Start" time has elapsed.
