3-16 Auto glow control
The glow will be turned ON for an optimum time according to the temperature of engine cooling water.
3-16-1 Key-ON Processing
Water temperature: The glow-ON time is obtained from the glow time map (see Fig. 1, 2). The glow will not,
however, turn ON while the engine is working or the temperature is 81 C or over. The glow icon will appear
with the glow turned ON.
When the user confirms that the glow icon turns OFF and tries starting the engine, a delay in response (usu-
ally 0.5 to 1.5 seconds) will result, during which the temperature of the glow plug will drop. Therefore, the
actual glow will be kept turned ON for 2 seconds after the glow icon disappears. This will make a response
time lag between the display and glow time, thus making it possible to start the engine smoothly. (See Fig.
3.)
