The INFINITI Direct Response Hybrid System
combines the power of a gasoline engine and an
electric motor to help minimize 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 condi-
tions.
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
If you continue to drive the vehicle while
the warning is displayed, the hybrid sys-
tem may become temporarily inoperative
and the system cannot provide power to
the wheels. This can result in reduced or
zero vehicle speed. The reduced speed or
zero speed may be lower than other traf-
fic, which could increase the chance of a
collision. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. If this occurs, place the
shift lever in the P (Park) position and the
ignition in the READY to drive position
with the vehicle stopped until the display
turns off. The hybrid system overheat
warning and the Shift to Park Li-ion bat-
tery low warning messages will be alter-
nately displayed. For additional informa-
tion, refer to “Shift to Park” in the
“Instruments and controls” section of this
manual.
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 serious 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 Response Hybrid
System.
The Li-ion battery has a limited service life. It is
recommended that you visit an INFINITI retailer
for information about recycling or disposal of the
battery.
INFINITI DIRECT RESPONSE HYBRID
SYSTEM LITHIUM-ION (Li-ion) BATTERY
HEV-2HEV Overview
The INFINITI Direct Response Hybrid System
monitors the energy flow between the electric
motor, the engine, the tires, and the 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 ve-
hicle information display and the meter. System
status can also be shown on the navigation sys-
tem display (if so equipped) when the screen is in
the energy flow mode or energy/fuel history
mode.
ASSIST CHARGE GAUGE
This meter displays the actual electric motor
power consumption and the charging power to
the Li-ion battery.
For additional information, refer to “Assist charge
gauge” in the “Instruments and controls” section
of this manual.
ENERGY FLOW (models with
navigation system)
When you use this system, make sure the hybrid
system is in the READY to drive mode. For addi-
tional information, refer to “Operation of the hy-
brid system” in this section.
If you use the system with the hybrid sys-
tem 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.
The energy monitor for various operating modes
can be displayed on the navigation system moni-
tor and the meter.
Press the INFO button on the control panel and
highlight the “Energy Flow” key on the display
using the INFINITI controller then press the EN-
TER button.

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 bat-
tery.
The following are displayed on the Energy Flow
display.● When the vehicle is powered only by the
electric motor or gasoline engine.
● When the vehicle is powered by both the
electric motor and the gasoline engine. ●
When the vehicle is charging the Li-ion bat-
tery with the regenerative brake or gasoline
engine.
● When the vehicle is powered by the gaso-
line engine and is charging the Li-ion battery.
● When there is no Energy Flow in the vehicle
The Energy Flow and remaining Li-ion battery

Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked. It is rec-
ommended that you visit an INFINITI retailer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade, quality
and viscosity engine oil to ensure satisfactory
engine life and performance. For additional infor-
mation, refer toRecommended fluids/lubricants
and capacities in this section. INFINITI recom-
mends the use of an energy conserving oil in
order to improve fuel economy.
Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval Committee (ILSAC) certification and SAE vis-
cosity standard. These oils have the API certifica-
tion mark on the front of the container. Oils which
do not have the specified quality label should not
be used as they could cause engine damage.Oil additives
INFINITI does not recommend the use of oil ad-
ditives. The use of an oil additive is not necessary
when the proper oil type is used and maintenance
intervals are followed.
Oil which may contain foreign matter or has been
previously used should not be used.
