2. High voltage harnesses (orange)
3. Lithium ion (Li-ion) battery
4. DC/DC converter
5. Service plug
6. Electric compressor7. Electric motor
8. 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. Becareful of both the high voltage and the
high temperature.
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.
JVO0019X
An air ventis located on the rear parcel
shelf to cool the Li-ion battery. If the vent is
covered, the battery will overheat resulting
in reduced output performance of the hybrid
system. See “Lithium-ion (Li-ion) battery air
vent” (P.7-5).

CAUTION
Do not place objects over or into the air
vent. The Li-ion battery 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.
JVO0020X
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.
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

WARNING AND INDICATOR LIGHTS

FRONT SEATS
Front power seat adjustment
Operating tips:
.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.
See “Automatic drive positioner” (P.3-28)
for the seat position memory function.
SSS1051
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 desired angle is obtained. To bring the
seatback forward again, move the switch
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. (See “Precautions on seat belt
usage” (P.1-9).) Also, the seatback can be
reclined to allow occupants to rest when the vehicle is parked.

JVI0196X
TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (RPM).Do not rev
the engine into the red zone
.
The scale length and the red zone vary with
the engine model.
CAUTION
When engine speed approaches the red
zone, shift to a higher gear or reduce
engine speed. Operating the engine in
the red zone may cause serious engine
damage.
JVI0197X
ASSIST CHARGE GAUGE
The gauge indicates the condition of the
electric motor.
When the needle is between the center and
the PWR
side, this indicates that the
electric motor is powering the drive wheels
and the Lithium-ion (Li-ion) battery is dis-
charging.
When the needle is between the center and
CHG
side, this indicates that the electric
motor is generating power to recharge the
Li-ion battery.
JVI0846X
FUEL GAUGE
The gauge indicates the approximatefuel
level in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down
hills.
The gauge needle returns to “0” (Empty)
after the ignition switch is pushed to the
OFF position.
Refill the fuel tank before the gauge
registers “0” (Empty).
The low fuel warning
appears on the
vehicle information display when the fuel
level is getting low. Refuel as soon as it is
convenient, preferably before the gauge
