Hybrid System-2Hybrid System Overview
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 conditions.
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
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.
Contact your INFINITI retailer for informa-
tion about recycling or disposal of the
battery.
WARNING
. The INFINITI Direct Response Hybrid®
System uses high voltage up to approxi-
mately 408 volts. The system can be hot
during and after starting. Be careful of
both the high voltage and the high
temperature. Obey the warning labels
attached to the vehicle.
. Never disassemble, remove or replace
high-voltage parts and harnesses as
well as their connectors. Doing so can
cause severe burns or electric shock that
may result in serious injury or death.
High-voltage harnesses are colored or-
ange. The vehicle high voltage system
has no user serviceable parts. Take your
vehicle to an INFINITI retailer for any
necessary maintenance.
. Never try to remove the service plug
located in the trunk. The service plug is
used only when the vehicle is serviced
by trained technicians wearing personal
protection equipment and is part of the
high voltage system. Touching the ser-
vice plug can cause severe burns or
electric shock that may result in serious
injury or death.

SYSTEM LITHIUM-ION (Li-ion) BATTERY HIGH VOLTAGE CAUTIONS
RAPID ACCELERATION
The vehicle is accelerated using both the
gasoline engine and the electric motor
depending on the available Li-ion battery
charge.
DECELERATION AND BRAKING
The Li-ion battery is charged by the electric
motor that changes the energy of the
rotating wheels into electric power. See
“Regenerative brake”(P.Hybrid System-8).
STOPPING
The gasoline engine may stop running to
save fuel depending on the available Li-ion
battery charge. The INFINITI Direct Response Hybrid
®
System monitors the status of power being
sent to the electric motor and the Lithium
ion (Li-ion) battery state of charge. The
status is shown on the assist charge gauge
in the meter and the energy flow/remain-
ing Li-ion battery charge in the dot matrix
display. System status can also be shown
on the navigation system display (if so
equipped) when the screen is in the energy
flow mode or energy/fuel history mode.

2. Fuel consumption in the past 12minutes: Fuel consumption in the past
12 minutes is displayed.
3. Current fuel consumption (Latest col- umn): The current fuel consumption is
calculated and displayed based on
distance and fuel consumption.
NOTE:
Information shown in the yellow column
means current (within 2 minutes) and
information shown in the blue columns
means past (more than 2 minutes). When the vehicle decelerates while the
vehicle is driven with the shift lever in the
D (drive) position or in the manual shift
mode, the Lithium ion (Li-ion) battery can
be charged by the electric motor. The
electric motor converts the energy of the
rotating wheels into electric power under
the following circumstances:
.
When the accelerator pedal is released.
. When the brake pedal is depressed
. When there is no malfunction in the
brake system or the INFINITI Direct
Response Hybrid
®System
The regenerative brake may not work
properly if the vehicle has tires and road
wheels other than the ones specified in
this manual. Drive your vehicle with smooth accelera-
tion and deceleration.
.
While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for most
efficient use, do not accelerate or
decelerate your vehicle more than
necessary.
. Avoid abrupt acceleration and decelera-
tion.
. The power of the Lithium ion (Li-ion)
battery can be checked on the Energy
Flow in the center display (models with
navigation system) or Li-ion battery
status meter in the dot matrix display.
See “Energy Flow (models with naviga-
tion system)” (P.Hybrid System-5) or
“Trip computer” (P.2-28). Gradual or
non-abrupt acceleration and decelera-
tion will make more effective use of the
electric motor power, using less gaso-
line engine power.
. When parking, be sure to place the shift
lever in the P (Park) position. While
driving, place the shift lever in the D
(Drive) position.

TIRE PRESSURE information
WARNING
. When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
The tire pressure will be displayed for
reference.
The pressure indication “*** kPa”or“***
psi ”on the screen means that the pressure
is being measured. After a few driving
trips, the pressure for each tire will be
displayed.
For models with navigation system, to
change the measurement units, select the
“Select Units” key with the INFINITI con-
troller and push the ENTER button.
15%.)
. E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and should
not be used. Damage caused by such
fuel is not covered by the INFINITI New
Vehicle Limited Warranty.
. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in INFINITI
vehicles.
If any undesirable driveability problems
such as engine stalling or hard hot starting
are experienced after using oxygenate-
blend fuels, immediately change to a
non-oxygenate fuel or a fuel with a low
blend of MTBE. Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.
E-15 fuel
E-15 fuel is a mixture of approximately
15% fuel ethanol and 85% unleaded
gasoline. E-15 can only be used in vehicles
designed to run on E-15 fuel. Do not use E-
15 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
E-85 fuel
E-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded
gasoline. E-85 can only be used in a
Flexible Fuel Vehicle (FFV). Do not use E-
85 fuel in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
Aftermarket fuel additives
INFINITI does not recommend the use of
any aftermarket fuel additives (Example:
fuel injector cleaner, octane booster, intake
valve deposit removers, etc.) which are
sold commercially. Many of these additives
intended for gum, varnish or deposit
removal may contain active solvent or
similar ingredients that can be harmful to
the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock.
(Spark knock is a metallic rapping noise.)
If severe, this can lead to engine damage.
If you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady speed
on level roads, have an INFINITI retailer
correct the condition. Failure to correct the
condition is misuse of the vehicle, for
which INFINITI is not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This in
turn may cause excessive fuel consumption
or damage to the engine. If any of the
