* status. Regener-
ated energy will be used to charge the
hybrid battery (traction battery).
*: When used in this manual, regeneration
refers to the conversion of energy cre-
ated by the movement of the vehicle into
electrical energy.
Hybrid Eco area
Shows that gasoline engine power is not being used very often.
The gasoline engine will automatically st op and restart under various conditions.
Eco area
Shows that the vehicle is being dr iven in an Eco-friendly manner.
By keeping the bar display within Eco area, more Eco-friendly driving can be achieved.
Power area
Shows that an Eco-friendly driving range is being exceeded (during full power driving
etc.)
If the shift lever is in N, the hybrid battery (traction battery) will not be charged even when
the engine is running. Therefore, if the vehicle is left with the shift lever in N for a certain
period of time, the hybrid battery (traction batt ery) will discharge, and this may result in the
vehicle not being able to start.
Hybrid System
Your vehicle is a Hybrid Electric Vehicle. It has characteristics different from conventional
vehicles. Be sure you are closely familiar with the characteristics of your vehicle, and
operate it with care.
The hybrid system combines the use of a gasoline engine and an electric motor (traction
motor) according to driving conditions, improving fuel efficiency and reducing exhaust
emissions.
For details, refer to the “OWNER’S MANUAL”.

In the following situations, kinetic energy is converted to electric energy and deceleration
force can be obtained in conjunction with the recharging of the hybrid battery (traction bat-
tery).
O The accelerator pedal is released while driving with the shift lever in D or S.
O The brake pedal is depressed while driv ing with the shift lever in D or S.
