●
When the desired speed is reached
Release the accelerator pedal
once. Then, depress the acceler-
ator pedal slowly and drive at a
constant speed, keeping the indi-
cator bar within the Eco area.
When aiming to improve fuel
economy, try to drive within the
Hybrid Eco area. By doing so,
the drive force of the electric
motor (traction motor) will often
be used alone without the need
for fuel consumption, thus allow-
ing you to enjoy driving with
improved fuel economy.
■ Checking fuel consumption
The 5-minute/1-minute interval
fuel consumption display shows
the average fuel consumption
and the regenerated energy
amount in 5-minute or 1-minute
intervals. (P. 194)

play shows a history of the aver-
age fuel consumption in
sections, based on the driving
records of trip meters A and B.
Each section represents the
interval between each trip meter
reset. (

A record of the best consumption
is also kept on this screen. The
best consumption record is
updated whenever a higher
