MEDIUM OR HIGH SPEED DRIVING
The system automatically controls the gasoline
engine and electric motor in order to obtain the
optimum fuel mileage and performance, depend-
ing on the driving situation and available Li-ion
battery charge.
When the remaining battery level is low, the Li-ion
battery is charged by the electric motor that is
driven to generate electric power while the ve-
hicle is driving.
RAPID ACCELERATION
The vehicle is accelerated using both the gaso-
line engine and the electric motor depending on
the available Li-ion battery charge.
DECELERATION AND BRAKING
The Li-ion battery is charged by the electric mo-
tor that changes the energy of the rotating
wheels into electric power. See “Regenerative
brake” later in this section.
STOPPING
The gasoline engine may stop running to save
fuel depending on the available Li-ion battery
charge.The INFINITI Direct Response Hybrid® System
monitors the status of power being sent to the
electric motor 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 dot
matrix display. System status can also be shown
on the navigation system display (if so equipped)
when the screen is in the energy flow mode or
energy/fuel history mode.
POWER METER
This meter displays the actual electric motor
power consumption and the charging power to
the Li-ion battery.
For additional information, See “Power meter” in
the “Instruments and controls” section.
ENERGY FLOW (models with
navigation system)
When you use this system, make sure the hybrid
system is in the READY to drive mode. See
“Operation of the hybrid system” in this section.

HEV OverviewHEV-5
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.
Energy monitor for various operating modes can
be displayed on the navigation system monitor.
Push the INFO button on the control panel and
highlight the “Energy Flow” key on the display
using the INFINITI controller then push the EN-
TER button.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
screen.● 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 and gaso-
line 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 dot matrix
display. See “Trip computer” in the “Instruments
and controls” section.

●Fuel consumption in the past 12 minutes:
Fuel consumption in the past 12 minutes is
displayed.
● Current fuel consumption (Latest 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) .This vehicle is equipped with two braking systems.
● 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 slight vibration or hear
the system working when braking. This is normal.
The regenerative cooperative brake system con-
trols both hydraulic and regenerative brakes. If
you feel unusual deceleration when braking, have
an INFINITI retailer check both the brake and
hybrid systems. 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 dot matrix
display. See “Energy Flow (models with
navigation system)” or “Trip computer” in the
“Instruments and controls” section. 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.

POWER METER
The power meter indicates the condition of the
electric motor. When the needle is between the
center and “charge” (
1range) , this indicates
that the electric motor is generating power to
recharge the Li-ion battery.
When the needle is between the center and the
PWR side, this indicates that the electric motor is
powering the drive wheels and the Li-ion battery
is discharging.

Anti-lock Braking System(ABS) warning light
When the ignition switch is placed in the ON
position, the Anti-lock Braking System (ABS)
warning light illuminates and then turns off. This
indicates the ABS is operational.
If the ABS light comes on while the hybrid system
is running, it may indicate the anti-lock braking
system is not functioning properly. Have the sys-
tem checked by an INFINITI retailer. If an ABS malfunction occurs, the anti-lock func-
tion is turned off. The brake system then operates
normally, but without anti-lock assistance. See
“Brake system” in the “Starting and driving” sec-
tion of the Owner’s Manual.
orBrake warning light
This light functions for both the parking brake and
the foot brake systems.
● Parking brake indicator
● Low brake fluid warning light
● Hydraulic brake system warning light Parking brake indicator
When the ignition switch is placed in the ON
position and the hybrid system is in the READY
mode, the light comes on when the parking brake
is applied.
Low brake fluid warning light
When the ignition switch is placed in the ON
position and the hybrid system is in the READY
mode, the light warns of a low brake fluid level.
Check the brake fluid level. Add brake fluid as
necessary. See “Brake fluid” in the Maintenance
and do-it-yourself” section of your INFINITI Own-
er’s Manual. If the brake fluid level is correct, see
“Hydraulic brake system warning light” in this
section.
