Hybrid 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-10). 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

delivered to an INFINITI retailer to
have the Li-ion battery pack and high
voltage parts such as the inverter,
including the wiring harness, re-
moved prior to painting. Li-ion bat-
tery packs exposed to heat in the
paint booth will experience capacity
loss. Damaged Li-ion battery packs
may also pose safety risks to un-
trained mechanics and repair person-
nel.

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 Hy-

brid

®

System malfunctions

For the above collisions and the certain
hybrid system malfunctions, the READY to
drive indicator light will turn off. See “Warn-
ing lights, indicator lights and audible re-
minders” (P.2-9).

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. If this occurs, it is recom-
mended that you contact an INFINITI re-
tailer. Even if the ignition switch is switched
to READY to drive position, the system may
shut-off suddenly. Therefore, drive cau-
tiously to the nearest INFINITI retailer or
contact an INFINITI retailer as soon as
possible.

To start the INFINITI Direct Response
Hybrid

®

System:

1. Depress the brake pedal and place the

ignition switch in the ON position when
the transmission is in the P (Park) or N
(Neutral) position (P is recommended).
(For more details, see “Push-button
ignition switch” (P.5-11).)

2. The READY to drive indicator light

flashes, then turns illuminated. (The
hybrid system switched to the READY
to drive mode when the indicator light
illuminates.)

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 low speed
driving, deceleration or when the vehicle is
stopped.

The gasoline engine may automatically run
in the following conditions:

. The level of remaining charge in the

Lithium ion (Li-ion) battery is low. The
engine runs to charge the Li-ion battery
and to provide power to the drive the
vehicle.

. The temperature of the engine coolant is

low.

SYSTEM

. 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 lower display and the
meter. System status can also be shown
when the screen is in the energy flow mode
or energy/fuel history mode.

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 economy history.

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 Lithium ion (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 follow-
ing circumstances:
. 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
Hybrid

®

System.

The regenerative brake may not work prop-
erly if the vehicle has tires and road wheels
other than the ones specified in this manual.

Drive your vehicle with smooth acceleration
and deceleration.
. While driving, energy is recovered

through the regenerative brake as the
vehicle decelerates. However, for most
efficient use, do not accelerate or de-
celerate your vehicle more than neces-
sary.

. Avoid abrupt acceleration and decelera-

tion.

. The power of the Lithium ion (Li-ion)

battery can be checked on the Energy
Flow or Energy monitor. See “Energy
Flow” (P.Hybrid System-6) or “Trip com-
puter” (P.2-27). Gradual or non-abrupt
acceleration and deceleration will make
more effective use of the electric power,
using less gasoline engine 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.

REGENERATIVE BRAKE

EFFICIENT USE OF YOUR VEHICLE

The Approaching Vehicle Sound for Pedes-
trians (VSP) system is a function that uses
sound to help alert pedestrians of the
presence of the vehicle when it is being
driven at a low speed in the electric drive
mode under the following conditions:
. The sound starts when the vehicle starts

accelerating.

. The sound stops when the vehicle speed

is more than 19 MPH (30 km/h) while
accelerating.

. The sound starts when the vehicle speed

is less than 16 MPH (25 km/h) while
decelerating.

. The sound stops when the vehicle stops.

. The sound does not stop with the vehicle

in the R (Reverse) position even if the
vehicle stops.

The VSP system is automatically turned on
when the vehicle is in the READY to drive
mode.

If there is a malfunction in the VSP system,
the VSP OFF indicator light in the meter
illuminates. See “Approaching Vehicle Sound
for Pedestrians (VSP) OFF indicator light”
(P.2-15).

WARNING

. If the sound from the VSP system is

not heard while driving, stop the
vehicle in a safe and quiet location.
Open a window, and then place the
vehicle in the R (Reverse) position
with the brake pedal firmly de-
pressed. Check that the operating
sound can be heard from the front
side of the vehicle.

. If the sound cannot be heard, have

the system immediately inspected. It
is recommended you visit an INFINITI
retailer for this service.

HYBRID VEHICLE PRECAUTIONS

HYBRID VEHICLE CHARACTER-
ISTICS

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
indicator light is on even if the gaso-
line engine 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 accelerator 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
battery is completely discharged and
the hybrid system cannot be activated,
it is recommended that you contact 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 of their
electromagnetic shieldings. Unwanted noise
may occur in the reception of a mobile two-
way radio.

Charging the Li-ion battery while driving is
important. The vehicle cannot run if the Li-
ion battery is discharged. When in the N
(Neutral), D (Drive) or R (Reverse) position,
and while the accelerator pedal or the brake
pedal is not depressed, the Li-ion battery
does not recharge. Leaving the transmission
in the N (Neutral), D (Drive) or R (Reverse)
position, and while the accelerator pedal or
the brake pedal is not depressed for an
extended period of time (for example, when
the shift lever is in the D (Drive) position and
the vehicle is stopped only by the parking
brake), may discharge the Li-ion battery and
the hybrid system may automatically be
turned off.

An air vent

is located on the right and left

sides between the rear seat and rear door to
cool the Li-ion battery and DC/DC conver-
ter. If the vent is covered, the Li-ion battery
or DC/DC converter will overheat resulting
in reduced output performance of the hybrid
system. See “Lithium-ion (Li-ion) battery
and DC/DC converter air vent” (P.7-5).

After the hybrid system is activated, the
following noises and vibrations that are
unique to the hybrid system may occur. This
does not indicate a malfunction.

. Electric motor noise from the engine

compartment

. Noise from the rear of the vehicle when

the hybrid system activates or deacti-
vates

. Noise and vibration when the gasoline

engine starts running or stops

. Operating noise or electric motor noise

when releasing the accelerator pedal or
depressing the brake pedal

. Engine noise due to rapid acceleration

. Fan noise from the air inlet located

between the rear seat and rear door

. Noise from the climate control system

. Noise from the vehicle in order to alert

pedestrians to the presence of an ap-
proaching vehicle. See “Approaching Ve-
hicle Sound for Pedestrians (VSP)
