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
WARNING
●The INFINITI Direct Response Hybrid
System uses high voltage up to approxi-
mately 168 volts. 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, harnesses and their
connectors. Touching, disassembling,
removing or replacing those parts and
harnesses can cause severe 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. It is recommended that you take
your vehicle to an INFINITI retailer for
any necessary maintenance.
● Never try to remove the service plug
located in the cargo area. 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. Touch-
ing the service plug can cause severe
burns or electric shock that may result
in serious injury or death.
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,
refer to “High-voltage components and
their locations” in this section. To avoid
personal injury, never touch high-
voltage wiring, connectors, and other
high-voltage parts, such as electric mo-
tor inverter and Li-ion battery. An elec-
tric shock may occur if exposed electric
wires are visible when viewed from in-
side or outside of your vehicle. There-
fore, never touch exposed 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 first
responders that this is a hybrid vehicle.
HIGH-VOLTAGE CAUTIONS ROAD ACCIDENT CAUTIONS
HEV OverviewHEV-3
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.

WARNING
●When you leave your vehicle, be sure to
place the ignition switch in the OFF
position.
LHV2040
HEV-12HEV Overview
●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.
CAUTION
●If the vehicle is parked for a long period
of time, the battery discharges gradu-
ally. To avoid this occurrence, drive the
vehicle for approximately 30 minutes at
least once every two to three months.
Otherwise, the Lithium ion (Li-ion) bat-
tery may be damaged. If the Li-ion bat-
tery is completely discharged and the
hybrid system cannot be activated, it is
recommended that you visit an INFINITI
retailer.
High-voltage parts and harnesses on the hybrid
vehicles emit approximately the same amount of
electromagnetic waves as the conventional gasoline-powered vehicles or home electronic
appliances despite their electromagnetic shield-
ings.
Charging the Li-ion battery while driving is impor-
tant. The vehicle cannot run if the Li-ion battery is
discharged. In the N (Neutral) position, the Li-ion
battery does not recharge. Leaving the transmis-
sion in the N (Neutral) position for an extended
period of time may discharge the Li-ion battery.
The Li-ion battery recharges when the shift lever
is in any position other than N (Neutral) .
An air vent is located on the rear side trim panels
Ato cool the high-voltage battery. If the vent is
covered, the battery will overheat resulting in
reduced output performance of the hybrid sys-
tem. For additional information, refer to “Lithium-
ion (Li-ion) battery air vent” in the “Appearance
and care” section of this manual.
You may hear the noise of the cooling fan from the
air vent.
CAUTION
Do not place objects over or into the air
vent. The Li-ion battery or DC/DC con-
verter may overheat and be damaged.

WARNING
●Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and receive
neck or other serious injuries. You
could also slide under the lap belt and
receive serious internal injuries. ●
For the most effective protection when
the vehicle is in motion, the seat should
be upright. Always sit well back and up-
right in the seat with both feet on the
floor and adjust the seat properly. For
additional information, refer to “Precau-
tions on seat belt usage” in this section.
●
After adjustment, gently rock in the seat
to make sure it is securely locked.
● Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents. ●
To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or
death to people and pets.
● Do not adjust the driver’s seat while
driving so full attention may be given to
vehicle operation. The seat may move
suddenly and could cause loss of con-
trol of the vehicle.
● The seatback should not be reclined
any more than needed for comfort. Seat
belts are most effective when the pas-
senger sits well back and straight up in
the seat. If the seatback is reclined, the
risk of sliding under the lap belt and
being injured is increased.
CAUTION
When adjusting the seat positions, be
sure not to contact any moving parts to
avoid possible injuries and/or damage.

●The power seat motor has an auto-reset
overload protection circuit. If the motor
stops during operation, wait 30 seconds,
then reactivate the switch.
● Do not operate the power seat switch for a
long period of time when the INFINITI Direct
Response Hybrid System is not running.
This will discharge the 12–volt battery. For additional information about automatic drive
positioner operation, refer to “Automatic drive
positioner” in the “Pre-driving checks and adjust-
ments” section of this manual.
Forward and backward
Moving the switch forward or backward will slide
the seat forward or backward to the desired
position.
Reclining
Move the recline switch backward until the de-
sired angle is obtained. To bring the seatback
forward again, move the switch forward and
move your body forward. The seatback will move
forward.
The reclining feature allows adjustment of the
seatback for occupants of different sizes for
added comfort and to help obtain proper seat
belt fit. For additional information, refer to “Pre-
cautions on seat belt usage” in this section. Also,
the seatback can be reclined to allow occupants
to rest when the vehicle is stopped and the shift
lever is in P (Park) .
