hi all. is there any criteria that need to be met so that the I-stop become active? normally, the engine shuts down when you press the brake deeper. but some times, the I-stop icon does not light up on the dash board or stop my engine when I deeply press the brake even though I have activated it via the button.
so wanted to know if it depends on the fuel consumption to start work, or if I need to stop frequently for it to start work.
please advise.

It depends on whether you have AC on, rear window heating on, if the temperature is too low, if the istop capacitor is charged enough.
Also, you have to go less than 6 kp/h or be standing still.

You need to read the manual to understand the limitations. I turn off i-Stop most of the time since I just find it irritating when I don't generally get stuck in traffic. i-Stop will not operate in UK cars under the following conditions:

o Cold engine
o Fuel injection learning is underway
o Battery is depleted
o Car driven only a short distance
o Bonnet, door or boot is open
o Driver’s seatbelt not fastened
o Aircon is in airflow mode or maximum cooling
o Aircon is cooling interior
o Problem with keyless entry
o Steering wheel is being operated
o Problem with brake vacuum
o High or low ambient temperature
o Low atmospheric pressure ( at altitude)
o Stopped on a steep slope
