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 the accelerator by anticipat-
ing a decelerating event* based on
the analysis of driving routes and
road conditions according to the nav-
igation system. It encourages the
driver to remove the foot from the
pedal and allow coasting down the
road with EV motor only. This helps
preventing unnecessary fuel con-
sumption and increases fuel efficien-
cy.❈
Example of a deceleration event is
going down an extended hill,
approaching a toll booth, and
approaching reduced speed
zones.
Press the Engine Start/Stop button
and put the shift lever in P(Park). In
the User Settings Mode, select
Driver assistance, Coasting Guide,
and then On to turn on the system.
Cancel the selection of coasting
guide to turn off the system. For the
explanation of the system, press and
hold the [OK] button.

To activate the system, take the fol-
lowing procedures. Enter your desti-
nation information on the navigation
and select the driving route. Select
the ECO mode in the Integrated
Driving Control System. Then, satisfy
the following.
- The driving speed should be
between 60 km/h (37 mph) and 160
km/h (99 mph).
❈ The operating speed may vary
due to difference between instru-
ment cluster and navigation effect-
ed by tire inflation level.
