Hybrid System-10Hybrid System Overview
HIGH VOLTAGE COMPONENTS
WARNING
.The INFINITI Direct Response Hy-
brid®System uses high voltage up to
approximately 408 volts. The system
can be hot while and after starting.
Be careful of both the high voltage
and the high temperature. Obey the
warning labels attached to the vehi-
cle.
. Never touch, disassemble, remove or
replace the high voltage parts, har-
nesses and their connectors. High
voltage harnesses are orange. Touch-
ing, disassembling, removing or re-
placing those parts and harnesses can
cause severe burns or electric shock
that may result in serious injury or
death.

2. High voltage harnesses (orange)
3. Lithium ion (Li-ion) battery
4. Electric compressor
5. Electric motor
6. 12-volt battery The hybrid system uses high voltage up to
approximately 408 volts. High voltage com-
ponents are indicated in the illustration. High
voltage harnesses are orange. The system
can be hot while and after starting. Be
careful of both the high voltage and the
high temperature.
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.
JVO0114X
An air ventis 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).

Hybrid System-12Hybrid System Overview
JVO0101X
CAUTION
.Do not allow any liquid to get on or in
the air vent. It may cause a short
circuit and damage the Li-ion battery
or DC/DC converter.
. Do not place objects over or into the
air vent. The Li-ion battery or DC/
DC converter may overheat and be
damaged.
JVO0006X
CAUTION
Do not load large amounts of water in
open containers (aquariums or buckets)
into the vehicle. If the water spills onto
the Li-ion battery, it may cause a short
circuit and damage the battery.
Noise and vibration
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)
system” (P.Hybrid System-9).
