NOTE: The cold start button, 1, does not need to be
held in during operation.
NOTE: A monitoring device prevents the heater from
working unless both the engine coolant and the
intercooler temperature are below 15 ° C (59 ° F).
NOTE: The preheat cycle will be deactivated if the
battery voltage drops below 9 Volts.
6. When the cold start light, 2, turns off, turn the key
switch to the “START” position.
7. If the engine does not start after 20 seconds of
cranking, turn the key switch to the ”OFF”
position, allow the starter to cool for two minutes,
then repeat the procedure starting at step 4.
8. When the engine starts (approximately 800
RPM) release the key switch. Check that all
warning lights extinguish and gauge readings
are normal.
NOTE: During cranking, the air inlet heater is off until
the engine achieves 400 RPM. At 400 RPM, the air
inlet heater will heat again in automatic or manual
mode, and remain on until the coolant and the
intercooler temperature are above 15 ° C (59 ° F). The
heater may automatically turn on and off for up to 20
minutes after the engine has started.

deactivated if the battery voltage drops below 10.5
Volts.
