Coasting guide (if equipped)
A chime will sound and the coasting
guide indicator will blink four times to
inform the driver when to take the
foot off from the accelerator by antic-
ipating a decelerating event* based
on the analysis of driving routes and
road conditions of the navigation. It
encourages the driver to remove foot
from the pedal and allow coasting
down the road with EV motor only.
This helps prevent unnecessary fuel
consumption and increases fuel effi-
ciency.
