Hybrid System-2Hybrid System Overview
The INFINITI Direct Response Hybrid®Sys-
tem combines the power of a gasoline
engine and an electric motor to help mini-
mize 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 conditions.
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 ser-
ious 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 Re-
sponse Hybrid
®System.
The Li-ion battery has a limited service life. It
is recommended that you contact your
INFINITI retailer for information about re-
cycling or disposal of the battery.
WARNING
. The INFINITI Direct Response Hy-
brid®System uses high voltage up to
approximately 408 volts. The system
can be hot during and after starting.
Be careful of both the high voltage
and the high temperature. Obey the
warning labels attached to the vehi-
cle.
. Never disassemble, remove or replace
high-voltage parts and harnesses as
well as their connectors. Doing so 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 service-
able parts. It is recommended that
you take your vehicle to an INFINITI
retailer for any necessary mainte-
nance.
. 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 wear-
ing personal protection equipment
and is part of the high voltage
system. Touching 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
vehicle off the road, put the trans-
mission in the P (Park) position, apply
the parking 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 loca-
tions, see “High voltage components”
(P.Hybrid System-9). To avoid per-
sonal injury, never touch high-vol-
tage wiring, connectors, and other
high-voltage parts, such as electric
motor inverter and Lithium ion (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 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 da- maged. Leave the vehicle as soon as
possible.
. Leaks or damage to the Li-ion bat-
tery may result in a fire. If you
discover them, contact emergency
services immediately. Since the fluid
leak may be lithium organic electro-
lyte 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 water and
receive immediate medical attention
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
extinguisher that is meant for use on
electrical fires. Using water or the
incorrect fire extinguisher can result
in serious injury or death from elec-
trical 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 ser-
vices. Advise 1st responders that this
is a hybrid vehicle.
. In the event of an accident that
requires body repair and painting, it
is recommended that the vehicle be

.Based on driving conditions.
. The shift lever is shifted to the P (Park)
position, the driver’s seat belt is re-
leased 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.
STARTING AND SLOW SPEED
DRIVING
The vehicle is driven by the electric motor
depending on the available Li-ion battery
charge.
MEDIUM OR HIGH SPEED DRIV-
ING
The system automatically controls the gaso-
line engine and electric motor in order to
obtain the optimum fuel mileage and per-
formance, depending 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 vehicle is driving.
RAPID ACCELERATION
The vehicle is accelerated using both the
gasoline 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
motor that changes the energy of the
rotating wheels into electric power. See
“Regenerative brake” (P.Hybrid System-8).
STOPPING
The gasoline engine may stop running to
save fuel depending on the available Li-ion
battery charge. The INFINITI Direct Response Hybrid
®Sys-
tem monitors the status of power being sent
to the electric motor and the Lithium ion (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 vehicle information
display. System status can also be shown
when the screen is in the energy flow mode
or energy/fuel history mode.

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 information display. See “Trip com-
puter” (P.2-28).
FUEL ECONOMY HISTORY
The Fuel Economy History screen appears in
the center display when the screen is in the
Fuel Economy History mode.
1. Push the INFO button on the control panel.
2. Touch [Fuel Economy History].
JVO0112X
The Fuel Economy History displays the
vehicle’s average fuel consumption and re-
generative electric power at 2 minute inter-
vals.
The displayed values on the screen indicate
general driving conditions. Accuracy varies
with driving habits and road conditions.
1. Regenerated energy in the past 12 minutes: The regenerated energy in the
past 12 minutes is indicated with sym-
bols
. One symbol indicates 30 watt-
hour. The energy of 30 watt-hour illu-
minates a 30 watt bulb for an hour.
2. Fuel consumption (without latest col- umn) in the past 12 minutes: Fuel con-
sumption in the past 12 minutes is displayed.
3. Current fuel consumption (Latest col- umn): The current fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption.
NOTE:
The fuel consumption displays on the upper
side of the fuel economy history display,
and the regenerated energy displays on the
lower side of the fuel economy history.
