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
●In the event of an accident that requires
body repair and painting, the vehicle
should be delivered to an INFINITI re-
tailer to have the Li-ion battery pack
and high-voltage parts such as the in-
verter, including the wiring harness, re-
moved prior to painting. Li-ion battery
packs exposed to heat in the paint
booth will experience capacity loss.
Damaged Li-ion battery packs may also
pose safety risks to untrained mechan-
ics and repair personnel. The emergency shut-off system is activated and
the high-voltage system automatically turns off in
the following conditions:
● Front and side collisions in which the air
bags are deployed
● Certain rear collisions
● Certain INFINITI Direct Response Hybrid
System malfunctions
For the above collisions and the certain hybrid
system malfunctions, the READY to drive indica-
tor light will turn off. For additional information,
refer to “Warning lights, indicator lights and au-
dible reminders” in the “Instruments and con-
trols” section of this manual.
The emergency shut-off activates for the above
collisions to minimize risk of an event that could
cause injury or an accident. If the emergency
shut-off system activates, the hybrid system may
not switch to the READY to drive position; it is
recommended that you visit an INFINITI retailer.
Even if the ignition switch is switched to the
READY to drive position, the system may shut off
suddenly. Therefore, drive cautiously to the near-
est INFINITI retailer or contact an INFINITI retailer
as soon as possible. To start the INFINITI Direct Response Hybrid
System, depress the brake pedal and place the
ignition switch in the ON position when the trans-
mission is in the P (Park) position or N (Neutral)
position (P is recommended) .
CAUTION
Do not start the system in N (Neutral)
position under cold condition of the sys-
tem. Start in the P (Park) position in that
case.
The READY to drive indicator light
flashes
until the hybrid system is ready to drive.
If starting in a low temperature environment, the
flashing time of the READY lamp becomes lon-
ger. It cannot move out from P (Park) during
flashing.
When the READY to drive indicator light
illuminates, the vehicle can be driven, even if the
gasoline engine is not running.
NOTE:
The gasoline engine starts and stops auto-
matically. It may stop during deceleration
or when the vehicle is stopped.
EMERGENCY SHUT-OFF SYSTEM OPERATION OF THE HYBRID SYSTEM
HEV-4HEV Overview
The INFINITI Direct Response Hybrid System
monitors the energy flow between the Li-ion bat-
tery, 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.

HYBRID VEHICLE
CHARACTERISTICS
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 indica-
tor light is on even if the gasoline en-
gine 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 accel-
erator 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 bat-
tery is completely discharged and the
hybrid system cannot be activated, it is
recommended that you visit 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 their electromagnetic shield-
ings.
Charging the Li-ion battery while driving is impor-
tant. 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 transmis-
sion 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) .

● If the seat belt warning light glows con-
tinuously while the ignition is turned
ON with all doors closed and all seat
belts fastened, it may indicate a mal-
function in the system. Have the system
checked. It is recommended that you
visit an INFINITI retailer for this service.
● No changes should be made to the seat
belt system. For example, do not modify
the seat belt, add material, or install
devices that may change the seat belt
routing or tension. Doing so may affect
the operation of the seat belt system.
Modifying or tampering with the seat
belt system may result in serious per-
sonal injury. ●
Once a seat belt pretensioner(s) have
activated, they cannot be reused and
must be replaced together with the re-
tractor. It is recommended that you visit
an INFINITI retailer for this service.
● All seat belt assemblies, including re-
tractors and attaching hardware, should
be inspected after any collision. It is
recommended that you visit an INFINITI
retailer for this service. INFINITI recom-
mends that all seat belt assemblies in
use during a collision be replaced un-
less the collision was minor and the
belts show no damage and continue to
operate properly. Seat belt assemblies
not in use during a collision should also
be inspected and replaced if either
damage or improper operation is noted.
● All child restraints and attaching hard-
ware should be inspected after any col-
lision. Always follow the restraint
manufacturer’s inspection instructions
and replacement recommendations.
The child restraints should be replaced

PRECAUTIONS ON SRS
This SRS section contains important information
concerning the following systems:
● Driver and front passenger supplemental
front-impact air bag (INFINITI Advanced Air
Bag System)
● Front seat-mounted side-impact supple-
mental air bag
● Roof-mounted curtain side-impact and roll-
over supplemental air bag
● Seat belt with pretensioner(s) (front seats)
Supplemental front-impact air bag system
The INFINITI Advanced Air Bag System can help
cushion the impact force to the head and chest of
the driver and front passenger in certain frontal
collisions.
Front seat-mounted side-impact supple-
mental air bag system
This system can help cushion the impact force to
the chest area of the driver and front passenger in
certain side-impact collisions. The side air bags
are designed to inflate on the side where the
vehicle is impacted. Roof-mounted curtain side-impact and
rollover supplemental air bag system
This system can help cushion the impact force to
the head of occupants in front and rear outboard
seating positions in certain side-impact or roll-
over collisions. In a side impact, the curtain air
bags are designed to inflate on the side where
the vehicle is impacted. In a rollover, the curtain
air bags are designed to inflate and remain in-
flated for a short time.
The SRS is designed to
supplementthe crash
protection provided by the driver and front pas-
senger seat belts and is not a substitutefor
them. Seat belts should always be correctly worn
and the occupant seated a suitable distance
away from the steering wheel, instrument panel
and door finishers. For additional information
about instructions and precautions on seat belt
usage, refer to “Seat belts” in this section.
The supplemental air bags operate only
when the ignition switch is placed in the ON
