This vehicle is equipped with two braking sys-
tems:● 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 a slight vibration or
hear the system working when braking. This is
normal. The regenerative cooperative brake system con-
trols both the hydraulic and regenerative brakes.
If you feel unusual deceleration when braking,
have the brake and hybrid systems checked. It is
recommended that you visit an INFINITI retailer
for this service.
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 vehicle
information display. For additional informa-
tion, refer to “Energy Flow (models with navi-
gation system)” in this section or “Trip com-
puter” in the “Instruments and controls”
section of this manual. 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.

HEV-10HEV Overview

The 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.
For additional information, refer to “Approaching
Vehicle Sound for Pedestrians (VSP) OFF indi-
cator light” in the “Instruments and controls” sec-
tion of this manual.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, it is rec-
ommended that you immediately con-
tact an INFINITI retailer for inspection.

perature. Obey the warning labels at-
tached to the vehicle.
● Never touch, disassemble, remove or
replace the high-voltage parts, har-
nesses and their connectors. High-
voltage harnesses are orange. Touch-
ing, disassembling, removing or
replacing those parts and harnesses

and damage the battery, Li-ion battery, or
DC/DC converter.
Noise and vibration
After the hybrid system is activated, the following
noises and vibrations that are unique to the hy-
brid system may occur. This does not indicate a
malfunction.● Electric motor noise from the engine com-
partment
● Noise from the rear of the vehicle when the
hybrid system activates or deactivates
● Noise and vibration when the gasoline en-
gine starts running or stops
● Operating noise or electric motor noise
when releasing the accelerator pedal or de-
pressing the brake pedal
● Engine noise due to rapid acceleration
● Fan noise from the air inlet located on the
rear parcel shelf ●
Noise from the climate control system
● Noise from the vehicle in order to alert pe-
destrians to the presence of an approaching

● the vehicle speed is under 10 mph (15 km/h)
during emergency braking.
● the vehicle speed is under 19 mph (30 km/h)
during sudden steering maneuvers or cer-
tain types of rollover collisions.
The pre-crash seat belt will not be active when
the brake pedal is not depressed except when
sudden steering maneuvers occur and the For-
ward Emergency Braking (FEB) (if so equipped)
activates.
The motor also retracts the seat belt when the
seat belt is fastened or unfastened. When the
seat belt is fastened, the motor tightens the seat
belt for a snug fit. When the seat belt is unfas-
tened, the motor retracts the seat belt. If the seat
belt is not fully retracted, the motor retracts the
seat belt when the door is opened.
