Hybrid System-6Hybrid System Overview
JVO0111X
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 on the vehicle
information display. (See “1. Energy moni-
tor” (P.2-31).)
This is an example of the Energy Flow
display. The Energy Flow display changes,
depending on the following operating
conditions. The graphic indicates the
amount of power in the Li-ion battery. The following are displayed on the Energy
Flow screen.
.
When the vehicle is powered only by
the electric motor.
. When the vehicle is powered only by
the gasoline engine.
. When the vehicle is powered by both
the electric motor and the gasoline
engine.
. When the vehicle is charging the Li-ion
battery with the regenerative brake and
gasoline engine.
. When the vehicle is charging the Li-ion
battery with the regenerative brake.
. When the vehicle is charging the Li-ion
battery with the gasoline engine.
. When the vehicle is powered by the
gasoline engine and is charging the Li-
ion battery.
. When there is no Energy Flow in the
vehicle
. When the vehicle is driving by the All-
Wheel Drive (AWD) (AWD models).
FUEL ECONOMY HISTORY
The Fuel Economy History screen appears
in the lower display when the screen is in
the Fuel Economy History mode.

Lithium ion (Li-ion) battery may be da-
maged. If the Li-ion battery is completely
discharged and the hybrid system cannot be
activated, 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 ve-
hicles or home electronic appliances de-
spite 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. In the N (Neutral)
position, the Li-ion battery does not
recharge. Leaving the transmission in the
N (Neutral) position for an extended period
of time may discharge the Li-ion battery.
The Li-ion battery recharges when the shift
lever is in any position other than N
(Neutral).

Left side
An air vent
*Ais located on the right and
left sides between the rear seat and rear
door to cool the Li-ion battery and DC/DC
converter. 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.7-6).
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 con-
verter may overheat and be damaged.

and the Li-ion battery is discharging.
JVI0640X
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 light
illuminates
on the meter when the fuel level is getting
low. Refuel as soon as it is convenient,

the charging system is not functioning
properly. See an INFINITI retailer immedi-
ately.
CAUTION
The charging system may not be functioning
properly if the 12-volt battery charge warn-
ing light comes on while the hybrid system
is running. The hybrid system will stop
operating when the 12-volt battery becomes
discharged. Immediately stop the vehicle in
a safe place and contact an INFINITI retailer.
orAnti-lock Braking
System (ABS) warning light
When the ignition switch is in the ON
position, the Anti-lock Braking System
(ABS) warning light illuminates and then
turns off. This indicates the ABS is opera-
tional.
If the ABS warning light illuminates while
the hybrid system is running, or while
driving, it may indicate the ABS is not
functioning properly. Have the system
checked by an INFINITI retailer.
If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system then operates normally, but without anti-
lock assistance. (See
“Anti-lock Braking
System (ABS)” (P.5-107).)
Brake system warning light
(yellow)
This light will illuminate after the hybrid
system is started and then turns off after a
few seconds.
WARNING
If both the brake system warning light
(yellow) and the brake warning light (red)
illuminate when the parking brake is re-
leased and the hybrid system is on, do not
drive the vehicle. More brake pedal effort
than normal will be required and there will
be a significant reduction in brake perfor-
mance, which could result in an accident.
Immediately stop the vehicle in a safe
location and contact an INFINITI retailer.
If the brake system warning light (yellow)
illuminates when the ignition switch is in
the ON position, it may indicate a malfunc-
tion in the brake system or one of the
following other functions. .
Regenerative brake system
. Hill start assist system
. Rise-up and build-up function
See an INFINITI retailer for an inspection as
soon as possible.
A chime sounds if a malfunction occurs in
the brake system power supply.
orBrake warning light
(red)
This light functions for both the parking
brake and the foot brake systems.
Parking brake indicator:
When the ignition switch is in the ON
position, the light comes on when the
parking brake is applied.
Low brake fluid warning:
When the ignition switch is in the ON
position, the light warns of a low brake
fluid level. If the light comes on with the
parking brake not applied, stop the vehicle
and perform the following:
1. Check the brake fluid level. If brake
fluid is low, add fluid and have the
system checked by your INFINITI retai-
ler. (See “Brake fluid” (P.8-15).)

The vehicle should be driven with the
Vehicle Dynamic Control (VDC) system on
for most driving conditions.
If the vehicle is stuck in mud or snow, the
VDC system reduces the output of the
INFINITI Direct Response Hybrid
®System
to reduce wheel spin. The speed of hybrid
system will be reduced even if the accel-
erator is depressed to the floor. If max-
imum power of the hybrid system is
needed to free a stuck vehicle, turn the
VDC system off.
To turn off the VDC system, push the VDC
OFF switch. The
indicator light will
illuminate. Push the VDC OFF switch again or restart
the hybrid system to turn on the system.
