i-stop INDICATOR LIGHT (GREEN) [SKYACTIV-G 2.0, SKYACTIV-G 2.5]


id0140g2008600


Purpose, Function

•  If the i-stop (engine stop control) permit condition is met while the vehicle is being driven, the i-stop indicator light (green) illuminates to inform the driver that an engine-stop by the i-stop control is permitted. In addition, if the engine cannot be stopped by the i-stop control due to insufficient depression of the brake pedal after the vehicle is stopped, the light flashes to warn the driver to further depress the brake pedal.
•  The light illuminates based on the i-stop (engine stop control) permit conditions.

Construction

•  The i-stop indicator light (green) is built into the instrument cluster.

Operation

•  The illumination/flashing conditions of the i-stop indicator light (green) differ depending on the i-stop (engine-stop control) permit condition.
•  The illumination/flashing conditions of the i-stop indicator light (green) are as follows:

*1  :After the vehicle is stopped, the engine stops if the gear is shifted to N position. In addition, if the gear is shifted to P position after the vehicle is stopped in D position, the engine stop condition by the i-stop control is maintained.
*2  :If the engine is started with the hood open, i-stop is inhibited until the engine is stopped.
*3  :If the seat belt is unfastened while the vehicle is stopped, i-stop is inhibited until a vehicle speed record is input once.
*4  :When the A/C set temperature is set to MAX, the PCM may inhibit the i-stop control.
