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. See “Warning/indicator
lights and audible reminders” in the “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 switch 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. 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) .
The READY to drive indicator light
flashes
until hybrid system becomes the ready to drive
mode.
If starting in low temperature environment, flash-
ing time of READY lamp becomes longer. It can-
not move out from P range 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.
The gasoline engine may automatically run in the
following conditions:
● The level of remaining charge in the Li-ion
battery is low. The engine runs to charge the
Li-ion battery and to provide power to drive
the vehicle.
● The temperature of the engine coolant is
low. ●
When A/C is used.
● When opening door.
● When engine hood is opened.
● When applying brakes.
● Based on driving conditions.
● The shift 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.
Engine is hard to stop during these driving con-
ditions: ● Outside temperature is high/low and A/C is
on.
● When repeatedly starting and stopping the
engine.
STARTING AND SLOW SPEED
DRIVING
In some cases, the vehicle can be driven by
electric motor during extremely slow speed
creep, but the engine starts when accelerating or
taking off the brakes.
EMERGENCY SHUT-OFF SYSTEM OPERATION OF THE HYBRID SYSTEM
HEV-4HEV Overview
If you use the system with the hybrid sys-
tem 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 on the navigation system monitor.
Push the INFO button on the control panel and
highlight the “Energy Flow” key on the display
using the INFINITI controller then push the EN-
TER button.This is an example of the Energy Flow display.
The Energy Flow display changes, depending on
the following operating conditions. The graphic
indicates the amount of power in the Li-ion bat-
tery.
The following are displayed on the Energy Flow
screen.● When the vehicle is powered only by the
electric motor or gasoline engine.
● When the vehicle is powered by both the
electric motor and the gasoline engine. ●
When the vehicle is charging the Li-ion bat-
tery with the regenerative brake and gaso-
line engine.
● When the vehicle is powered by the gaso-
line engine and is charging the Li-ion battery.
● When there is no Energy Flow in the vehicle
The Energy Flow and remaining Li-ion battery
charge can be also shown on the dot matrix
display. See “Trip computer” in the “Instruments
and controls” section.

●Fuel consumption in the past 12 minutes:
Fuel consumption in the past 12 minutes is
displayed.
● Current fuel consumption (Latest column):
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 infor-
mation shown in the blue columns means
past (more than 2 minutes) .This vehicle is equipped with two braking systems.
● Hydraulic brake system
● Regenerative brake system
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 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 circum-
stances: ● 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 Hy-
brid® System
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.
While the regenerative cooperative brake system
is operating, you might feel slight vibration or hear
the system working when braking. This is normal.
The regenerative cooperative brake system con-
trols both hydraulic and regenerative brakes. If
you feel unusual deceleration when braking, have
an INFINITI retailer check both the brake and
hybrid systems. Drive your vehicle with smooth accelera-
tion and deceleration.
● While driving, energy is recovered through
the regenerative brake as the vehicle decel-
erates. However, for most efficient use, do
not accelerate or decelerate your vehicle
more than necessary.
● Avoid abrupt acceleration and deceleration.
● The power of the 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
navigation system)” or “Trip computer” in the
“Instruments and controls” section. Gradual
or non-abrupt acceleration and deceleration
will make more effective use of the electric
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.

The Approaching Vehicle Sound for Pedestrians
(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 con-
ditions:● The sound starts when the vehicle starts
accelerating.
● The sound stops when the vehicle speed is
more than 19 MPH (30 km/h) while acceler-
ating only when vehicle is powered by the
electric motor.
● The sound starts when the vehicle speed is
less than 16 MPH (25 km/h) while deceler-
ating only when vehicle is powered by the
electric motor.
● 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.

ans (VSP) OFF indicator light” in the “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 (Re-
verse) position with the brake pedal
firmly depressed. Check that the oper-
ating sound can be heard from the front
side of the vehicle.
● If the sound cannot be heard, immedi-
ately contact an INFINITI retailer for
inspection.
