The INFINITI Direct Response Hybrid System
monitors the energy flow between the electric
motor, the engine, the tires, and the Li-ion battery
state of charge. The status is shown on the assist
charge gauge in the meter and the energy
flow/remaining Li-ion battery charge in the ve-
hicle information display and the meter. System
status can also be shown on the navigation sys-
tem display (if so equipped) when the screen is in
the energy flow mode or energy/fuel history
mode.
ASSIST CHARGE GAUGE
This meter displays the actual electric motor
power consumption and the charging power to
the Li-ion battery.
For additional information, refer to “Assist charge
gauge” in the “Instruments and controls” section
of this manual.
ENERGY FLOW (models with
navigation system)
When you use this system, make sure the hybrid
system is in the READY to drive mode. For addi-
tional information, refer to “Operation of the hy-
brid system” in this section.
If you use the system with the hybrid sys-
tem off (ignition switch placed in the ACC
position) for a long time, it will discharge
the 12-volt battery power, and the hybrid
system will not start.
The energy monitor for various operating modes
can be displayed on the navigation system moni-
tor and the meter.
Press the INFO button on the control panel and
highlight the “Energy Flow” key on the display
using the INFINITI controller then press the EN-
TER button.

HEV-6HEV Overview
This is an example of the Energy Flow display.
The Energy Flow display changes, depending on
the following operating conditions. The graphic
indicates the amount of power in the Li-ion bat-
tery.
The following are displayed on the Energy Flow
display.● When the vehicle is powered only by the
electric motor or gasoline engine.
● When the vehicle is powered by both the
electric motor and the gasoline engine. ●
When the vehicle is charging the Li-ion bat-
tery with the regenerative brake or gasoline
engine.
● When the vehicle is powered by the gaso-
line engine and is charging the Li-ion battery.
● When there is no Energy Flow in the vehicle
The Energy Flow and remaining Li-ion battery
charge can be also shown on the vehicle infor-
mation display. For additional information, refer to
“Vehicle information display” in the “Instruments
and controls” section of this manual.FUEL ECONOMY (models with
navigation system)
Press the INFO button, then touch the FUEL
ECONOMY key on the display screen.
This screen displays the rate of fuel consumption
and distance to empty.

Press the INFO button, then select the FUEL
ECONOMY key on the display screen.
This screen displays the rate of fuel consumption
and distance to empty.
FUEL ECONOMY HISTORY (models
with navigation system)
The Fuel Eco History screen appears in the dis-
play with the navigation system when the screen
is in the Fuel Eco History mode.1. Press the INFO button on the control panel and highlight the “Energy Flow” key on the
display using the INFINITI controller. Then
press the ENTER button.
2. Highlight the “History” key, and press the ENTER button. The Fuel Eco History can be displayed on the
navigation system monitor. This displays the ve-
hicle’s average fuel consumption and regenera-
tive electric power at 2 minute intervals.
The displayed values on the screen indicate gen-
eral driving conditions. Accuracy varies with driv-
ing habits and road conditions.
1. Regenerated energy in the past 12 minutes: The regenerated energy in the past 12 min-
utes is indicated with symbols. One symbol
indicates 30 watt-hour. The energy of a
30 watt-hour illuminates a 30 watt bulb for
an hour.
2. Fuel consumption in the past 12 minutes: Fuel consumption in the past 12 minutes is
displayed.
3. Current fuel consumption (Last column): The current fuel consumption is calculated
and displayed based on distance and fuel
consumption.
NOTE:
Information shown in the yellow column
means current (within 2 minutes) and infor-
mation shown in the blue columns means
past (more than 2 minutes) .

HEV OverviewHEV-9
This vehicle is equipped with two braking sys-
tems:● Hydraulic brake system
● Regenerative brake system
When the vehicle decelerates while the vehicle is
driven with the shift lever in the D (Drive) position
or in the manual shift mode, the Li-ion battery can
be charged by the electric motor. The electric
motor converts the energy of the rotating wheels
into electric power under the following circum-
stances: ● When the accelerator pedal is released
● When the brake pedal is depressed
● When there is no malfunction in the brake
system or the INFINITI Direct Response Hy-
brid System
The regenerative brake may not work properly if
the vehicle is installed with tires and road wheels
other than the ones specified in this manual.
While the regenerative cooperative brake system
is operating, you might feel a slight vibration or
hear the system working when braking. This is
normal. The regenerative cooperative brake system con-
trols both the hydraulic and regenerative brakes.
If you feel unusual deceleration when braking,
have the brake and hybrid systems checked. It is
recommended that you visit an INFINITI retailer
for this service.
Drive your vehicle with smooth accelera-
tion and deceleration.
● While driving, energy is recovered through
the regenerative brake as the vehicle decel-
erates. However, for most efficient use, do
not accelerate or decelerate your vehicle
more than necessary.
● Avoid abrupt acceleration and deceleration.
● The power of the Li-ion battery can be
checked on the Energy Flow in the center
display (models with navigation system) or
Li-ion battery status meter in the vehicle
information display. For additional informa-
tion, refer to “Energy Flow (models with navi-
gation system)” in this section or “Trip com-
puter” in the “Instruments and controls”
section of this manual. Gradual or non-
abrupt acceleration and deceleration will
make more effective use of the electric
power.
● When parking, be sure to place the shift
lever in the P (Park) position. While driving,
place the shift lever in the D (Drive) position.
