The Hybrid System Indicator can be displayed on the sub-screen of the
main display ( P. 122) and the head-up display (if equipped)
( P. 158).
■
How to read the display
Charge area

Eco area
Shows that the vehicle is being driven in an Eco-friendly manne r.
Power area
Shows that an Eco-friendly driving range is being exceeded (dur ing full
power driving etc.)

● By keeping the indicator within Eco area, more Eco-friendly dri v-
ing can be achieved.
● Charge area indicates regeneration
*4 status. Regenerated
energy will be used to charge the hybrid battery (traction battery).
*1: Not displayed on the sub-screen.
*2: Not displayed on the sub-screen or head-up display.
*3: The EV indicator function can be turned off in the “Meter Cust omize”
settings. ( P. 153)
*4: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical e nergy.
■
“ECO Accelerator Guidance”
A blue zone is displayed in the
Eco area which can be used as
a reference operation range for
using the accelerator pedal
according to driving conditions
such as starting off and cruis-
ing.
The “ECO Accelerator Guid-
ance” display changes accord-
ing to the driving status, such as
when starting off or cruising.
It is easier to drive in an Eco-friendly manner by driving according to the
display showing the accelerator pedal operations and staying wi thin the
“ECO Accelerator Guidance” range. ( P. 229)
The “ECO Accelerator Guidance” function can be turned off in the
“Meter Customize” settings. ( P. 153)

■Eco score
The driving status for the following 3 situations are evaluated in 5
levels: Smooth start-off acceleration (“Eco-Start”), driving wi thout
sudden acceleration (“Eco-Cruise”) and smooth stopping (“Eco-
Stop”). Each time the vehicle i s stopped, a score result is displayed
out of a perfect score of 100 points.
Score result
“Eco-Start” status
“Eco-Cruise” status
“Eco-Stop” status
How to read the bar display:
*: For items not currently evaluated, the display reads 0.
● The Eco score is reset each time the vehicle starts off to star t a new
evaluation.
● When the shift position is P, only the Eco score display area i s
enlarged and displayed. When the shift position is shifted from P,
the display returns to normal.
● When the hybrid system stops, the current total score result an d
advice on how to increase th e score are displayed. (P. 102)

■When operation of each function stops
● The Hybrid System Indicator stops operating in the following si tuations.
• The “READY” indicator is not illuminated.
• The shift position is not D or B.
● The Eco score and “ECO Accelerator Guidance” stop operating in the fol-
lowing situations.
• The Hybrid System Indicator is not operating.
• Cruise control (if equipped) or dynamic radar cruise control w ith full-
speed range (if equipped) is being used.
■ About the Eco score
●After starting off, Eco score display does not start until the vehicle speed
exceeds approximately 19 mph (30 km/h).
● In addition to the vehicle driving status, the Eco score also e valuates the air
conditioning system usage condition ( P. 148). The score displayed when
the hybrid system stops is the total result of the driving stat us after the
hybrid system starts and the air conditioning usage condition.
■ Predictive Efficient Drive (Pre dictive Deceleration Support) (vehicles
with 11.6-inch display)
When a predictive deceleration support point registered in the navigation sys-
tem is approached, the system turns off the Eco accelerator gui de and
informs the driver of releasing the accelerator pedal early.
For details about Predictive Efficient Drive (Predictive Decele ration Support),
refer to “NAVIGATION SYSTEM OWNER’S MANUAL”.

◆“Fuel Consumption Record”
The transitions of the average fuel consumption after the hybrid
system starts can be checked in such a unit as every 5 minutes or
every 1 mile (1.6 km)
*1 or 1 km (0.6 mile)*2 of driving. Also, it is
possible to check the average fu el consumption history for each
month by switching to the “Monthly” display.
*1: When the unit is set to “MPH”
*2: When the unit is set to “km/h”
■
How to read the screen
The “5 min” display is shown as an example. However, the basic
method for how to read the screen is the same for each fuel con -
sumption history screen.
