All-Wheel Drive (AWD) models
If you use the system with the hybrid
system off (ignition switch placed in the
ACC position) for a long time, it will
discharge the 12-volt battery power, and
the hybrid system will not start.
Energy monitor for various operating modes
can be displayed in the lower display.
The energy flow is also displayed in the
vehicle information display. (See “1. Energy
monitor” (P.2-27).)
This is an example of the Energy Flow
display. The Energy Flow display changes,
depending on the following operating con-
ditions. The graphic indicates the amount of
power in the Li-ion battery. The following are displayed on the Energy
Flow screen.

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).

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.
JVI0683X
ASSIST CHARGE GAUGE
The gauge indicates the condition of the
electric motor.
When the needle is between the center and
“charge”
side, this indicates that the
electric motor is generating power to re-
charge the Li-ion battery.
When the needle is between the center and
the PWR
side, this indicates that the
electric motor is powering the drive wheels
and the Li-ion battery is discharging.
JVI0640X
FUEL GAUGE

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 light
illuminates on
the meter when the fuel level is getting low.
Refuel as soon as it is convenient, preferably
before the gauge reaches “0”. There will be a

The 12-volt batteryis located on the left
hand side of the trunk behind an access
panel.
. Keep the battery surface clean and dry.
Clean the battery with a solution of
baking soda and water.
. Make certain the terminal connections
are clean and securely tightened.
. If the vehicle is not to be used for 30 days
or longer, disconnect the negative (-)
battery terminal cable to prevent dis-
charging it.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery discharge and potential no-start conditions
such as:
1.
Installation or extended use of electro-
nic accessories that consume 12-volt
battery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the 12-volt battery may
need to be charged to maintain 12-volt
battery health.WARNING
. Do not expose the 12-volt battery to
flames or electrical sparks. Hydrogen
gas generated by the 12-volt battery
is explosive. Do not allow battery
fluid to contact your skin, eyes,
fabrics or painted surfaces. After
touching a 12-volt battery, do not
touch or rub your eyes. Thoroughly
wash your hands. If the acid contacts
your eyes, skin or clothing, immedi-
ately flush with water for at least 15
minutes and seek medical attention.
. The hybrid vehicle uses a special
battery. If the 12-volt battery needs
to be replaced, use a 12-volt battery
of the same design. Using the wrong battery can cause hydrogen gas to
build up in the vehicle, which could
lead to an explosion and personal
injury.
