The INFINITI Direct Response Hybrid System
combines the power of a gasoline engine and an
electric motor to help minimize fuel consumption
and emissions.
Depending on driving conditions, the vehicle runs
on a combination of the gasoline engine and the
electric motor, whichever is best for those condi-
tions.
Because the gasoline engine charges the
Lithium-ion (Li-ion) battery as needed, the battery
does not have to be charged from an outside
source like an all-electric vehicle.WARNING
If you continue to drive the vehicle while
the warning is displayed, the hybrid sys-
tem may become temporarily inoperative
and the system cannot provide power to
the wheels. This can result in reduced or
zero vehicle speed. The reduced speed or
zero speed may be lower than other traf-
fic, which could increase the chance of a
collision. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. If this occurs, place the
shift lever in the P (Park) position and the
ignition in the READY to drive position
with the vehicle stopped until the display
turns off. The hybrid system overheat
warning and the Shift to Park Li-ion bat-
tery low warning messages will be alter-
nately displayed. For additional informa-
tion, refer to “Shift to Park” in the
“Instruments and controls” section of this
manual.
WARNING
Your vehicle contains a sealed Lithium-ion
(Li-ion) high-voltage battery. If the Li-ion
battery is disposed of improperly, there is
a risk of severe burns and electrical shock
that may result in serious injury or death
and there is also a risk of environmental
damage.
CAUTION
●Do not misuse the Li-ion battery.
● Do not use the Li-ion battery for any
other purpose.
The Li-ion battery is used to drive the electric
motors in the INFINITI Direct Response Hybrid
System.
The Li-ion battery has a limited service life. It is
recommended that you visit an INFINITI retailer
for information about recycling or disposal of the
battery.
INFINITI DIRECT RESPONSE HYBRID
SYSTEM LITHIUM-ION (Li-ion) BATTERY
HEV-2HEV Overview
The INFINITI Direct Response Hybrid System
monitors the energy flow between the Li-ion bat-
tery, 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.
Highlight the “Energy Flow” key on the display by
using the INFINITI controller and press the EN-
TER button or select the “Energy Flow” key by
touching the touch-screen.

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

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.

INFORMATION AND SETTINGS
Monitor, climate, audio, phone and voice recognition systems4-13
roads, it is recommended that you have an
INFINITI retailer correct the condition. Fail-
ure to correct the condition is misuse of the
vehicle, for which INFINITI is not respon-
sible.Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked. It is rec-
ommended that you visit an INFINITI retailer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
