Dear xxx,
Thank you for contacting your Honda Digital Team.
The ECON mode helps you improve the fuel economy by adjusting the performance of the climate control system and the accelerator pedal response. To turn it on and off, press the ECON button when the power mode in ON.
I have attached a screenshot of the owners manual page where you can find how to turn on the ECON mode (page XXX). You can also access the online owner's manual for further information on this feature : OWNER’S MANUAL LINK
If you are still unable to activate this feature, please visit one of our local Honda dealers, who can also assist you with it. Here's a link where you can locate your nearest dealership: add link
It is worth noting that due to emergency brakes operation or driving conditions, you may not be able to change the mode.
Once again, thank you for contacting your Honda Digital Team.
Kind Regards
