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

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
inspection.
