EMS INSTRUMENT CLUSTER CONTINUED
Engine Pre-Heat (Wait to Start)
0004
There are certain conditions imposed on the start circuit for reasons of safety. The machine must meet these conditions before
the engine can be started:
1. The air intake heaters (grid heaters) must have completed their initial cycle and the Wait-to-Start lamp (Figure 47, Item
25) is deactivated.
2.
The engine must not already be running.
3.
The gear selection column switch must be in Neutral.
4.
The ignition switch must be turned to position 3 (to enable the starter motor to be energized).
Before the engine is cranked, the air intake heaters (grid heaters) are activated. This happens regardless of temperature. In cer-
tain conditions the air intake heaters can remain active or be reactivated by the engine ECU while the engine is running.
When the ignition is turned ON, the warning light (Figure 47, Item 25) will be illuminated, the internal buzzer will sound, and
the LCD will display the message "WAIT TO START." Once the air intake heaters (grid heaters) have completed their cycle,
the warning light (Figure 47, Item 25) will be extinguished and the LCD message will change to "OK TO START" (for 3 sec-
onds or until the engine is running). This will inform the driver that the pre-heating has finished and the engine can be started.
