EV driving range
The EV driving range displayed on the multi-information display shows the refer-
ence distance that EV driving (driving using only the electric motor) is possible,
and the actual distance that can be driven may differ from that displayed. Even if
the EV driving range is displayed, EV driving may be canceled and both gasoline
engine and electric motor are used depending on the situation.
The value displayed on EV driving range is estimated from the following informa-
tion.
● The amount of hybrid battery (traction battery) charge currently remaining
●
The electricity consumption (the estimated distance that EV driving is possible
per unit of electrical energy) based on the recorded value
●
Past air conditioning system electricity consumption amount
The electricity consumption varies depending on how the vehicle is driven. The
vehicle automatically records the electricity consumption when being charged and
uses the electricity consumption for estimating the EV driving range. Therefore,
the EV driving range displayed when the hybrid battery (traction battery) is fully
charged may differ from the previous EV driving range depending on how the
vehicle was driven.
The EV driving range may change significantly with each charging until the elec-
tricity consumption based on the recorded value is stable (for approximately the
first month or two). However, this does not indicate a malfunction.
As the power consumption becomes high when the air conditioning system is on,
based on previous air conditioning system power consumption data, the EV driving
range when the air conditioning system is operating will be estimated.
Tips for extending the EV driving range
The distance that EV driving is possible varies significantly depending on how the
vehicle is driven, road conditions, the weather, the outside temperature, usage
conditions of electrical components and the number of occupants.
The distance that EV driving is possible can be extended if the following is per-
formed:
■ When starting off, accelerate using gradual accelerator pedal operation
As a guide, accelerate up to approximately 20 km/h (12mph) in the first 5
seconds.
Electrical and fuel efficiency can be improved just by taking care to start off gently.
