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.

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

■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.

*2 is greater
than that of the comparison vehicle, an estimation
*3 of the amount
of the fuel cost savings is displayed.
“FUEL COST”
If information about the vehicle used to compare fuel consumpti on
(“COMP. Consumption”) is not entered, an estimation
