.Based on driving conditions.
. The shift lever is shifted to the P (Park)
position, the driver’s seat belt is re-
leased and the driver’s side door is then
opened.
The hybrid system operates as follows based
on driving conditions and the Li-ion battery
charge.
STARTING AND SLOW SPEED
DRIVING
The vehicle is driven by the electric motor
depending on the available Li-ion battery
charge.
MEDIUM OR HIGH SPEED DRIV-
ING
The system automatically controls the gaso-
line engine and electric motor in order to
obtain the optimum fuel mileage and per-
formance, depending on the driving situation
and available Li-ion battery charge.
When the remaining battery level is low, the
Li-ion battery is charged by the electric
motor that is driven to generate electric
power while the vehicle is driving.
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
®Sys-
tem 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/remaining Li-ion
battery charge in the lower display and the
meter. System status can also be shown
when the screen is in the energy flow mode
or energy/fuel history mode.

charge gauge” (P.2-7).
ENERGY FLOW
When you use this system, make sure the
hybrid system is in the READY to drive mode.
See “Operation of the INFINITI Direct
Response Hybrid
®System” (P.Hybrid Sys-
tem-4).

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.
.
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.

3. Current fuel consumption (Latest col- umn): The current fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption.
NOTE:
The fuel consumption displays on the upper
side of the fuel economy history display,
and the regenerated energy displays on the
lower side of the economy history. 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 follow-
ing 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 prop-
erly if the vehicle has tires and road wheels
other than the ones specified in this manual. Drive your vehicle with smooth acceleration
and deceleration.
.
While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for most
efficient use, do not accelerate or de-
celerate your vehicle more than neces-
sary.
. Avoid abrupt acceleration and decelera-
tion.
. The power of the Lithium ion (Li-ion)
battery can be checked on the Energy
Flow or Energy monitor. See “Energy
Flow” (P.Hybrid System-6) or “Trip com-
puter” (P.2-27). Gradual or non-abrupt
acceleration and deceleration will make
more effective use of the electric power,
using less gasoline 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.

PRECAUTIONS ON SUPPLE-
MENTAL RESTRAINT SYSTEM
This Supplemental Restraint System (SRS)
section contains important information con-
cerning the following systems:
.Driver and passenger front-impact sup-
plemental air bags (INFINITI Advanced
Air Bag System)
. Front seat-mounted side-impact supple-
mental air bag
. Roof-mounted curtain side-impact and
rollover supplemental air bag
. Seat belt with pretensioner
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 and
pelvis area of the driver and front passenger
in certain side impact collisions. The side air
bag is designed to inflate on the side where
the vehicle is impacted.
Roof-mounted curtain side-impact and roll-
over 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 rollover 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 on both sides
are designed to inflate and remain inflated
for a short time.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments may cause the curtain air bags to
inflate.
These supplemental restraint systems are
designed to
supplement the crash protection
provided by the driver and passenger seat
belts and are not a substitute for 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. (See “Seat belts”
(P.1-9) for instructions and precautions on
seat belt usage.)
The supplemental air bags operate only
when the ignition switch is in the ON
position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the systems are operational.

WARNING
.The front air bags ordinarily will not
inflate in the event of a side impact,
rear impact, rollover, or lower sever-
ity frontal collision. Always wear
your seat belts to help reduce the
risk or severity of injury in various
kinds of accidents.
. The front passenger air bag will not
inflate if the passenger air bag status
light is lit. See “Front passenger air
bag and status light” (P.1-45).
. The seat belts and the front air bags
are most effective when you are
sitting well back and upright in the
seat with both feet on the floor. The
front air bags inflate with great
force. Even with the INFINITI Ad-
vanced Air Bag System, if you are
unrestrained, leaning forward, sitting
sideways or out of position in any
way, you are at greater risk of injury
or death in a crash. You may also
receive serious or fatal injuries from
the front air bag if you are up against
it when it inflates. Always sit back
against the seatback and as far-away
as practical from the steering wheel
or instrument panel. Always use the
seat belts.

.The driver and front passenger seat
belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The Advanced Air Bag
System monitors the severity of a
collision and seat belt usage then
inflates the air bags as needed. Fail-
ure to properly wear seat belts can
increase the risk or severity of injury
in an accident.
. The front passenger seat is equipped
with occupant classification sensors
(weight sensors) that turn the front
passenger air bag OFF under some
conditions. These sensors are only
used in this seat. Failure to be
properly seated and wearing the seat
belt can increase the risk or severity
of injury in an accident. See “Front
passenger air bag and status light”
(P.1-45).
. Keep hands on the outside of the
steering wheel. Placing them inside
the steering wheel rim could increase
the risk of injury if the front air bag
inflates.

.Make sure that there is no object
placed between the seat cushion and
center console or between the seat
cushion and the door.
. Be sure that the front passenger seat
does not contact the rear seat, in-
strument panel, etc., or the head
restraint does not contact the roof.
. Confirm the operating condition with
the front passenger air bag status
light.
. If you notice that the front passenger
air bag status light is not operating
as described in this section, it is
recommended you visit an INFINITI
retailer to check the passenger seat
Advanced Air Bag System.
. Until you have confirmed with a
retailer that your passenger seat
Advanced Air Bag System is working
properly, position the occupants in
the rear seating positions.
. Do not position the front passenger
seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may flash.
This vehicle is equipped with the INFINITI
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada. All of the information, cautions and
warnings in this manual apply and must be
followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
instrument panel above the glove box. The
front air bags are designed to inflate in
higher severity frontal collisions, although
they may inflate if the forces in another type
of collision are similar to those of a higher
severity frontal impact. They may not inflate
in certain frontal collisions. Vehicle damage
(or lack of it) is not always an indication of
proper front air bag operation.
The INFINITI Advanced Air Bag System has
dual stage air bag inflators. The system
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle switches and the occupant
classification sensors (weight sensors). In-
flator operation is based on the severity of a
collision and seat belt usage for the driver. For the front passenger, the occupant
classification sensors are also monitored.
Based on information from the sensors, only
one front air bag may inflate in a crash,
depending on the crash severity and whether
the front occupants are belted or unbelted.
Additionally, the front passenger air bag
may be automatically turned OFF under
some conditions, depending on the informa-
tion provided by the occupant classification
sensors. If the front passenger air bag is
OFF, the front passenger air bag status light
will be illuminated. (See “Front passenger air
bag and status light” (P.1-45) for further
details.) One front air bag inflating does not
indicate improper performance of the sys-
tem.
If you have any questions about your air bag
system, it is recommended you visit an
INFINITI retailer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-
ability, you may also contact an INFINITI
retailer. Contact information is contained in
the front of this Owner’s Manual.
When a front air bag inflates, a fairly loud
noise may be heard, followed by release of
smoke. This smoke is not harmful and does
not indicate a fire. Care should be taken not
to inhale it, as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.

Front air bags, along with the use of seat
belts, help to cushion the impact force on the
head and chest of the front occupants. They
can help save lives and reduce serious
injuries. However, an inflating front air bag
may cause facial abrasions or other injuries.
Front air bags do not provide restraint to the
lower body.
Even with INFINITI advanced air bags, seat
belts should be correctly worn and the driver
and passenger seated upright as far as
practical away from the steering wheel or
instrument panel. The front air bags inflate
quickly in order to help protect the front
occupants. Because of this, the force of the
front air bag inflating can increase the risk of
injury if the occupant is too close to, or is
against, the air bag module during inflation.
The front air bags deflate quickly after a
collision.
The front air bags operate only when the
ignition switch is in the ON position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.
