■ 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”.

is necessary to refrain from activities such as sudden accelera tion. (P. 427)
■ Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the r ain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properl y.
■ Restraining the hybrid system o utput (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
hybrid system output may be restrained.

It is easier to drive in an Eco-friendly manner by driving whil e referring to the
“ECO Accelerator Guidance” display. Also, by using the “ECO Accelerator
Guidance”, it is easier to increase the Eco score evaluation.
● When starting off:
While staying within the “ECO Accelerator Guidance” range, gradually
depress the accelerator pedal and accelerate to the desired spe ed. If exces-
sive acceleration is avoided, the “Eco-Start” score will increa se.
● When driving:
After accelerating to the desired speed, release the accelerato r pedal and
drive at a stable speed within the “ECO Accelerator Guidance” range. By
keeping the vehicle within the “ECO Accelerator Guidance” range, the “Eco-
Cruise” score will increase.
● When stopping:
