Charge area
Shows regeneration
* status. Regener-
ated energy will be used to charge the
hybrid battery (traction battery).
*: When used in this manual, “regenera-
tion” refers to the conversion of energy
created 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 stop 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 with in Eco area, more Eco-friendly driving can be achieved.

If the shift lever is in N, th e 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 battery) will discharge, and this may result in the
vehicle not being able to start.
Hybrid System
Your vehicle is a hybrid vehicle. It has charac teristics 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 gaso line engine and an electric motor (traction
motor) according to driving conditions, impr oving 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).
● The accelerator pedal is released while driving with the shift lever in D or S.
● The brake pedal is depressed while driv ing with the shift lever in D or S.
There may be no engine sound or vibration even though the vehicle is able to move with the
“READY” indicator is illuminated. For safety, apply the parking brake and make sure to shift
the shift lever to P when parked.
The following sounds or vibrat ions may occur when the hybrid system is operating and are
not a malfunction:
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid syst em starts or stops.
● Relay operating sounds such as a snap or so ft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear seats, when the hybrid system is started or
stopped.
● Sounds from the hybrid system may be heard when the trunk lid is open.
● Sounds may be heard from the transmission when the gasoline engine starts or stops,
when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is depressed or
as the accelerator pedal is released.
● Vibration may be felt when the gasoline engi ne starts or stops.
● Cooling fan sounds may be heard from th e air intake vent under the rear seat.
