Hybrid System-4Hybrid System Overview
delivered to an INFINITI retailer to
have the Li-ion battery pack and high
voltage parts such as the inverter,
including the wiring harness, re-
moved prior to painting. Li-ion bat-
tery packs exposed to heat in the
paint booth will experience capacity
loss. Damaged Li-ion battery packs
may also pose safety risks to un-
trained mechanics and repair person-
nel.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 Hy-
brid
®System malfunctions
For the above collisions and the certain
hybrid system malfunctions, the READY to
drive indicator light will turn off. See “Warn-
ing lights, indicator lights and audible re-
minders” (P.2-9).
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 READY to
drive position. If this occurs, it is recom-
mended that you contact an INFINITI re-
tailer. Even if the ignition switch is switched
to READY to drive position, the system may
shut-off suddenly. Therefore, drive cau-
tiously to the nearest INFINITI retailer or
contact an INFINITI retailer as soon as
possible. To start the INFINITI Direct Response
Hybrid
®System:
1. Depress the brake pedal and place the ignition switch in the ON position when
the transmission is in the P (Park) or N
(Neutral) position (P is recommended).
(For more details, see “Push-button
ignition switch” (P.5-11).)
2. The READY to drive indicator light
flashes, then turns illuminated. (The
hybrid system switched to the READY
to drive mode when the indicator light
illuminates.)
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 low speed
driving, deceleration or when the vehicle is
stopped.
The gasoline engine may automatically run
in the following conditions:
. The level of remaining charge in the
Lithium ion (Li-ion) battery is low. The
engine runs to charge the Li-ion battery
and to provide power to the drive the
vehicle.
. The temperature of the engine coolant is
low.

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.
REGENERATIVE BRAKEEFFICIENT USE OF YOUR VEHICLE

The Approaching Vehicle Sound for Pedes-
trians (VSP) system is a function that uses
sound to help alert pedestrians of the
presence of the vehicle when it is being
driven at a low speed in the electric drive
mode under the following conditions:
.The sound starts when the vehicle starts
accelerating.
. The sound stops when the vehicle speed
is more than 19 MPH (30 km/h) while
accelerating.
. The sound starts when the vehicle speed
is less than 16 MPH (25 km/h) while
decelerating.
. The sound stops when the vehicle stops.
. The sound does not stop with the vehicle
in the R (Reverse) position even if the
vehicle stops.
The VSP system is automatically turned on
when the vehicle is in the READY to drive
mode.
If there is a malfunction in the VSP system,
the VSP OFF indicator light in the meter
illuminates. See “Approaching Vehicle Sound
for Pedestrians (VSP) OFF indicator light”
(P.2-15).
WARNING
. If the sound from the VSP system is
not heard while driving, stop the
vehicle in a safe and quiet location.
Open a window, and then place the
vehicle in the R (Reverse) position
with the brake pedal firmly de-
pressed. Check that the operating
sound can be heard from the front
side of the vehicle.
. If the sound cannot be heard, have
the system immediately inspected. It
is recommended you visit an INFINITI
retailer for this service.

COCKPIT

1-12Safety — Seats, seat belts and supplemental restraint system
THREE-POINT TYPE SEAT BELT
WARNING
.Every person who drives or rides in
this vehicle should use a seat belt at
all times.
. Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and
receive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries.
. For the most effective protection
when the vehicle is in motion, the
seat should be upright. Always sit
well back and upright in the seat with
both feet on the floor and adjust the
seat belt properly.
. Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking
Retractor (ALR) mode seat belts. If
the seat belt becomes wrapped
around a child’s neck with the ALR
mode activated, the child can be
seriously injured or killed if the seat
belt retracts and becomes tight. This can occur even if the vehicle is
parked. Unbuckle the seat belt to
release the child. If the seat belt can
not be unbuckled or is already un-
buckled, release the child by cutting
the seat belt with a suitable tool
(such as a knife or scissors) to release
the seat belt.
SSS0292
Fastening the seat belts
1. Adjust the seat. (See “Seats” (P.1-2).)
2. Slowly pull the seat belt out of the
retractor and insert the tongue into the
buckle until you hear and feel the latch
engage.
.The retractor is designed to lockduring a sudden stop or on impact.
A slow pulling motion permits the
belt to move, and allows you some
freedom of movement in the seat.
.If the seat belt cannot be pulled from its fully retracted position, firmly pull
the belt and release it. Then smoothly
pull the belt out of the retractor.

1-16Safety — Seats, seat belts and supplemental restraint system
WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes tight.
This can occur even if the vehicle is
parked. Unbuckle the seat belt to release
the child. If the seat belt can not be
unbuckled or is already unbuckled, re-
lease the child by cutting the seat belt
with a suitable tool (such as a knife or
scissors) to release the seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available
from many other sources, including doctors,
teachers, government traffic safety offices,
and community organizations. Every child is
different, so be sure to learn the best way to
transport your child.
There are three basic types of child restraint
systems: .
Rear-facing child restraint
. Forward-facing child restraint
. Booster seat
The proper restraint depends on the child’s
size. Generally, infants up to about 1 year
and less than 20 lbs (9 kg) should be placed
in rear-facing child restraints. Forward-
facing child restraints are available for
children who outgrow rear-facing child re-
straints and are at least 1 year old. Booster
seats are used to help position a vehicle lap/
shoulder belt on a child who can no longer
use a forward-facing child restraint.
WARNING
Infants and children need special protec-
tion. The vehicle’s seat belts may not fit
them properly. The shoulder belt may
come too close to the face or neck. The
lap belt may not fit over their small hip
bones. In an accident, an improperly
fitting seat belt could cause serious or
fatal injury. Always use appropriate
child restraints.
All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children. See
“Child restraints” (P.1-18). A child restraint may be secured in the
vehicle by using either the LATCH (Lower
Anchor and Tethers for CHildren) system or
with the vehicle seat belt. See “Child re-
straints” (P.1-18) for more information.
INFINITI recommends that all pre-teens and
children be restrained in the rear seat.
Studies show that children are safer when
properly restrained in the rear seat than in
the front seat.
This is especially important because your
vehicle has a supplemental restraint system
(Air bag system) for the front passenger.
See “Supplemental restraint system” (P.1-
37).INFANTS
Infants up to at least 1 year old should be
placed in a rear-facing child restraint.
INFINITI recommends that infants be placed
in child restraints that comply with Federal
Motor Vehicle Safety Standards or Cana-
dian Motor Vehicle Safety Standards. You
should choose a child restraint that fits your
vehicle and always follow the manufac-
turer’s instructions for installation and use.
