- When the key switch is turned to "ON" position, the
display unit determines whether the preheating(or
post heating) is necessary or not using temperature
input signal from coolant temperature sensor. If the
coolant is less than 30
°C (86°F), the display unit gives
the signal to glow relay to activate glow plugs for 15
seconds of preheating time. At the same time, the dis-
play unit also gives the power to glow indication lamp on
the dash board for 8 seconds.
- The preheating seconds and indication seconds can
be shortened by turning the key switch to start posi-
tion and another 15 seconds of post heating starts
when the key is returned to "ON" position. The indi-
cation lamp is not activated during the post heating
period.

• The post heating process makes the combustion
condition of engine better to reduce harmful
emissions which can be produced a lot right after
engine start in cold weather. It also helps engine
to reach its normal running condition faster by
expediting the warm-up process.
