Hybrid System
■Hybrid System Indicator

Pow e r a r e a
Eco Driving Indicator Light turns off
●By keeping the indicator needle within Eco area, environmentally-friendly driving can be
achieved.
Hybrid Eco area shows that gasoline engine power is not being used very often.*

●Charge area indicates regeneration*2 status. Regenerated energy will be used to charge
the hybrid battery.
*
1: The gasoline engine will automatically stop and restart under various conditions.
*
2: When used in this manual, “regeneration” refers to the conversion of energy created by
the movement of the vehicle into electrical energy.
■Charging the battery
When shift position N is selected, the hybrid battery (traction battery) will not be charged.
Thus, select P when the vehicle is stopped.
In addition, when driving in heavy traffic, use D or B.
■Regenerative braking
The motor generator converts kinetic energy to electric energy when:
●The accelerator pedal is released while driving with shift position D or B selected.
●The brake pedal is depressed while driving with shift position D or B selected.
Your vehicle is a hybrid vehicle. It has characteristics different from conventional vehicles. Be
sure you are closely familiar with the characteristics of your vehicle, and operate 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”.

■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to move. Always
change the shift position to P when parked.
The following sounds or vibrations 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 system starts or stops.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transaxle when the hybrid system starts or stops, or while
the vehicle is idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is depressed
and accelerator is loosened.
●Other sounds, such as motors and mechanical noises, may be heard from the brake sys-
tem when the brake pedal is depressed.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent on the side of rear left seat-
back.
When driving in Eco mode, the fan noise may be louder than when driving normally.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light go off. If there is
only a small amount of fuel, the hybrid system may not be able to start.
(The minimum amount of fuel to add to make the low fuel level warning light go out is more
than 2.6 gal. [10 L, 2.1 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
Energy Monitor / Consumption Screen
■Energy monitor
The energy monitor can be displayed on both the navigation system screen and the multi-
information display.
●How to display on the navigation system screen (P. 3 8 ) :
Press the “MENU” button, and select “Info. Phone” after that select “Fuel consumption”.
If the “Consumption” or “Past Record” screen is displayed, select the “Energy” and press
the “ENTER” button.
●How to display on the multi-information display:
Toggle the “ENTER” switch on the steering wheel upward or downward through several
times to select the energy monitor display.
You can view the status of your hybrid system on the multi-information display and the
navigation system screen.

Decreases the speed
Hold the lever until the desired speed
setting is obtained.
Fine adjustment of the set speed can be
made by lightly pushing the lever up or
down and releasing it.
■Canceling and resuming the constant speed control

Cruise control switch
Dynamic radar cruise control supplements conventional cruise control with a vehicle-to-
vehicle distance control. In vehicle-to-vehicle distance control mode, the vehicle automat-
ically accelerates or decelerates in order to maintain a set following distance from vehi-
cles ahead.
