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.
❈Example of a deceleration event is
going down an extended hill, slow-
ing down 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
Driving Assist, 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 37 mph (60 km/h) and 99
mph (160 km/h).
❈ The operating speed may vary
due to difference between instru-
ment cluster and navigation effect-
ed by tire inflation level.
✽ ✽ NOTICE
Coasting guide is only a supplemen-
tal system to assist with fuel-efficient
driving. Thus, the operating condi-
tions may be different in accordance
with traffic/road conditions (i.e.
driving in a traffic jam, driving on a
slope, driving on a curve). Thus,
take the actual driving conditions
into consideration, such as distances
from the vehicles ahead/ behind,
while referring to the coasting guide
system as guidance.
