4.4.1. Operation in winter time
Operation 1 : Turn the key switch to the HEAT position, then the pilot lamp lights up for
about 20 seconds When the pilot lamp is extinguished, do operation 2.
Behavior – When the coolant temperature is below 10 °C in cold weather, you’d better
operate the pre-heating system (Air heater).
– If the pre-heating is not necessary, the pre-heating system is not operated
with the pilot lamp.
Operation 2 : After checking the pilot lamp, turn the key switch to the START position
to crank the engine, at once.
Behavior – When the key switch is placed in the START position, air heater is
continuously heated to facilitate starting operation and to reduce white
smoke automatically.
If the coolant temperature is above 10 °C, air eater needs not be heated.
Operation 3 : After the engine is cranked, convert the key switch to the ON position.
Behavior – As the engine is cranked, air heater is heated for 120 seconds (2 minute
after-heating) to reduce and to element quickly white smoke.
