After the hybrid system is started,
the Eco score will not be displayed
until the vehicle speed exceeds
approximately 19 mph (30 km/h).
The Eco score will be reset each
time the hybrid system is started.
■Elapsed time after start-
ing/EV Driving RatioEV driving ratio after starting
The percent traveled using only
electric motor power after starting
the hybrid system is displayed.

■Electricity consumption
When the unit is set to “miles/kWh”:
Electricity consum ption is the con-
sumption rate of the electricity when
EV driving is performed and equiva-
lent to the fuel consumption for the
gasoline vehicles. For this vehicle,
driven distance per kWh of electric-
ity consumed (“miles/kWh”) is dis-
played as electricity consumption on
each screen.
When the unit is set to “km/kWh” or
“kWh/100km”: Electricity consump-
tion is the consumption rate of the
electricity when EV driving is per-
formed and equivalent to the fuel
consumption for the gasoline vehi-
cles. For this vehicl e, electricity con-
sumed per 100 km (“kWh/100 km”)
or driven distance per kWh of elec-
tricity consumed (“km/kWh”) is dis-
played as electricity consumption on
each screen.

■Pre-collision brake assist
If the system determines that
the possibility of a collision is
high and the brake operation by
the driver is insufficient, the
braking power will be increased.
■Pre-collision brake control
If the system determines that
the possibility of a collision is
extremely high, the brakes are
automatically applied to help
avoid the collision or reduce the
impact of the collision.
■Emergency steering assist
If the system determines that
the following conditions are met,
assistance will be provided to
help enhance vehicle stability
and prevent lane departure.
During assistance, in addition to
the pre-collision warning, the fol-
lowing icon will be displayed on
the multi-information display.
 The possibility of a collision is
high
 There is sufficient space
within the lane to perform
evasive steering maneuvers
 The driver is operating the steering wheel
Vehicles with active steering
function: The brakes and steer-
ing are controlled to help avoid a
collision or reduce the impact of
a collision, regardless of the
evasive steering maneuvers
performed by the driver.
During assistance, the pre-colli-
sion warning will operate and a
message will be displayed to
warn the driver.
■Intersection collision avoid-
ance support (left/right
turn)
In situations such as the follow-
ing, if the system determines
that the possibility of a collision
is high, the pre-collision warning
and pre-collision braking will
operate.
Depending on the intersection,
assistance may not operate cor-
rectly.
 When turning left/right at an
intersection and crossing the
path of an oncoming vehicle
