WARNING
In case of a collision:
.If your vehicle is drivable, pull your
vehicle off the road, put the transmis-
sion in the P (Park) position, apply the
parking brake and turn the INFINITI
Direct Response Hybrid
TMSystem off.
. Check to see if there are exposed high
voltage parts and cables. Never touch
the parts and cables. For their locations,
see “High voltage components” later in
this section. To avoid personal injury,
never touch high-voltage wiring, con-
nectors, and other high-voltage parts,
such as electric motor inverter and
Lithium ion (Li-ion) battery. An electric
shock may occur if exposed electric
wires are visible when viewed from
inside or outside of your vehicle. There-
fore, never touch exposed electric wires.
. If the vehicle receives a strong impact to
the floor while driving, stop the vehicle
in a safe location and check the floor.
. Inspect the ground under the vehicle. If
liquid has leaked onto the ground, the
fuel system may have been damaged. Leave the vehicle as soon as possible.
. Leaks or damage to the Li-ion battery
may result in a fire. If you discover them,
contact emergency services immedi-
ately. Since the fluid leak may be lithium
organic electrolyte from the Li-ion bat-
tery, never touch the fluid leak inside or
outside the vehicle. If the fluid contacts
your skin or eyes, wash it off immedi-
ately with a large amount of water and
receive immediate medical attention to
help avoid serious injury.
. If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Only use a type ABC, BC or C fire
extinguisher that is meant for use on
electrical fires. Using water or the
incorrect fire extinguisher can result in
serious injury or death from electrical
shock.
. If you are not able to safely assess the
vehicle due to vehicle damage, do not
touch the vehicle. Leave the vehicle and
contact emergency services. Advise 1st
responders that this is a hybrid vehicle.
. In the event of an accident that requires
body repair and painting, the vehicle
should be delivered to an INFINITI retailer to have the Li-ion battery pack
and high voltage parts such as the
inverter, including the wiring harness,
removed 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 mechanics
and repair personnel.

ROAD ACCIDENT CAUTIONS

Hybrid System-4Hybrid System Overview
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
TMSystem malfunctions
For the above collisions and the certain
hybrid system malfunctions, the READY to
drive indicator light will turn off. See
“Warning/indicator lights and audible re-
minders” in the“2. Instruments and
controls”.
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
switched to READY to drive position,
contact an INFINITI retailer. Even if the
ignition switch is switched to READY to
drive position, the system may shut-off
suddenly. Therefore, drive cautiously to the
nearest INFINITI retailer or contact an
INFINITI retailer as soon as possible. Depress the brake pedal and place the
ignition switch in the ON position when the
transmission is in the P (Park) position or N
(Neutral) position (P is recommended) to
start the INFINITI Direct Response Hybrid
TM
System.
The READY to drive indicator light
flashes until hybrid system becomes the
ready to drive mode.
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
automatically. 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. .
Based on driving conditions.
. The selector lever is shifted to the P
(Park) position, the driver’s seat belt is
released 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 DRIV-
ING
The vehicle is driven by the electric motor
depending on the available Li-ion battery
charge.
MEDIUM OR HIGH SPEED DRIVING
The system automatically controls the
gasoline engine and electric motor in order
to obtain the optimum fuel mileage and
performance, 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.
EMERGENCY SHUT-OFF SYSTEM OPERATION OF THE HYBRID SYSTEM

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”later in this section.
STOPPING
The gasoline engine may stop running to
save fuel depending on the available Li-ion
battery charge. The INFINITI Direct Response Hybrid
TM
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 selector 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
TMSystem
The regenerative brake may not work
properly if the vehicle is installed with
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)” or“Trip computer” in the
“2. Instruments and controls” section.
Gradual or non-abrupt acceleration and
deceleration will make more effective
use of the electric using gasoline
engine power.
. When parking, be sure to place the
selector lever in the P (Park) position.
While driving, place the selector lever
in the D (Drive) position.
REGENERATIVE BRAKE EFFICIENT 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” in the “2. Instruments and controls”
section.
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 depressed. Check that the operat-
ing sound can be heard from the front
side of the vehicle.
. If the sound cannot be heard, immedi-
ately contact an INFINITI retailer for
