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
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 of Li-ion battery (to use the
Li-ion battery for completely another
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. Con-
tact your INFINITI retailer for information about
recycling or disposal of the battery.
WARNING
● The INFINITI Direct Response Hybrid®
System uses high voltage up to approxi-
mately 144volts. The system can be hot
while and after starting. Be careful of
both the high voltage and the high tem-
perature. Obey the warning labels at-
tached to the vehicle.
● Never disassemble, remove or replace
high-voltage parts and harnesses as
well as their connectors can cause se-
vere burns or electric shock that may
result in serious injury or death. High-
voltage harnesses are colored orange.
The vehicle high-voltage system has no
user serviceable parts. Take your ve-
hicle to an INFINITI retailer for any nec-
essary maintenance.
● Never try to remove the service plug
located in the trunk. The service plug is
used only when the vehicle is serviced
by trained technicians wearing personal
protection equipment and is part of the
high-voltage system. Touching the ser-
vice plug can cause severe burns or
electric shock that may result in serious
injury or death.

HEV-2HEV Overview

WARNING
In case of a collision:
●If your vehicle is drivable, pull your ve-
hicle off the road, put the transmission
in the P (Park) position, apply the park-
ing brake and turn the INFINITI Direct
Response Hybrid® System off.
● Check to see if there are exposed high-
voltage parts and cables. Never touch
the parts and cables. For their locations,
see “High-voltage components” later in
this section. To avoid personal injury,
never touch high-voltage wiring, con-
nectors, and other high-voltage parts,
such as electric motor inverter and Li-
ion battery. An electric shock may occur
if exposed electric wires are visible
when viewed from inside or outside of
your vehicle. Therefore, never touch ex-
posed electric wires.
● If the vehicle receives a strong impact to
the floor while driving, stop the vehicle
in a safe location and check the floor.
● Inspect the ground under the vehicle. If
liquid has leaked onto the ground, the
fuel system may have been damaged.
Leave the vehicle as soon as possible. ●
Leaks or damage to the Li-ion battery
may result in a fire. If you discover them,
contact emergency services immedi-
ately. Since the fluid leak may be
lithium organic electrolyte from the Li-
ion battery, never touch the fluid leak
inside or outside the vehicle. If the fluid
contacts your skin or eyes, wash it off
immediately with a large amount of wa-
ter and receive immediate medical at-
tention to help avoid serious injury.
● If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Only use a type ABC, BC or C fire extin-
guisher that is meant for use on electri-
cal fires. Using water or the incorrect
fire extinguisher can result in serious
injury or death from electrical shock.
● If you are not able to safely assess the
vehicle due to vehicle damage, do not
touch the vehicle. Leave the vehicle and
contact emergency services. Advise 1st
responders that this is a hybrid vehicle. ●
In the event of an accident that requires
body repair and painting, the vehicle
should be delivered to an INFINITI re-
tailer to have the Li-ion battery pack
and high-voltage parts such as the in-
verter, including the wiring harness, re-
moved prior to painting. Li-ion battery
packs exposed to heat in the paint
booth will experience capacity loss.
Damaged Li-ion battery packs may also
pose safety risks to untrained mechan-
ics and repair personnel.
ROAD ACCIDENT CAUTIONS
HEV OverviewHEV-3

The emergency shut-off system is activated and
the high-voltage system automatically turns off in
the following conditions:● Front and side collisions in which the air
bags are deployed.
● Certain rear collisions.
● Certain INFINITI Direct Response Hybrid®
System malfunctions
For the above collisions and the certain hybrid
system malfunctions, the READY to drive indica-
tor light will turn off. See “Warning/indicator
lights and audible reminders” in the “Instruments
and controls”.
The emergency shut-off activates for the above
collisions to minimize risk of an event that could
cause injury or an accident. If the emergency
shut-off system activates, the hybrid system may
not switch to READY to drive position, contact an
INFINITI retailer. Even if the ignition switch is
switched to READY to drive position, the system
may shut off suddenly. Therefore, drive cautiously
to the nearest INFINITI retailer or contact an
INFINITI retailer as soon as possible. To start the INFINITI Direct Response Hybrid®
System, depress the brake pedal and place the
ignition switch in the ON position when the trans-
mission is in the P (Park) position or N (Neutral)
position (P is recommended) .
The READY to drive indicator light
flashes
until hybrid system becomes the ready to drive
mode.
If starting in low temperature environment, flash-
ing time of READY lamp becomes longer. It can-
not move out from P range during flashing.
When the READY to drive indicator light
illuminates, the vehicle can be driven, even if the
gasoline engine is not running.
NOTE:
The gasoline engine starts and stops auto-
matically. It may stop during deceleration
or when the vehicle is stopped.
The gasoline engine may automatically run in the
following conditions:
● The level of remaining charge in the Li-ion
battery is low. The engine runs to charge the
Li-ion battery and to provide power to drive
the vehicle.
● The temperature of the engine coolant is
low. ●
When A/C is used.
● When opening door.
● When engine hood is opened.
● When applying brakes.
● Based on driving conditions.
● The shift lever is shifted to the P (Park)
position, the driver’s seat belt is released
and the driver’s side door is then opened.
The hybrid system operates as follows based on
driving conditions and the Li-ion battery charge.
Engine is hard to stop during these driving con-
ditions: ● Outside temperature is high/low and A/C is
on.
● When repeatedly starting and stopping the
engine.
STARTING AND SLOW SPEED
DRIVING
In some cases, the vehicle can be driven by
electric motor during extremely slow speed
creep, but the engine starts when accelerating or
taking off the brakes.
EMERGENCY SHUT-OFF SYSTEM OPERATION OF THE HYBRID SYSTEM
HEV-4HEV Overview

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.

ENERGY MONITORS
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.

WARNING
●When you leave your vehicle, be sure to
place the ignition switch in the OFF
position.
● Be sure to put the transmission in the P
(Park) position because the vehicle can
move when the READY to drive indica-
tor light is on even if the gasoline en-
gine is not running. When the READY to
drive indicator light is on, do not leave
your vehicle in a shift position other
than the P (Park) position. The vehicle
will creep and start abruptly if the accel-
erator pedal is depressed by mistake.
This may cause serious injury or death.
