●In the event of an accident that requires
body repair and painting, the vehicle
should be delivered to an INFINITI re-
tailer to have the Li-ion battery pack
and high-voltage parts such as the in-
verter, including the wiring harness, re-
moved 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 mechan-
ics and repair personnel. 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. For additional information,
refer to “Warning lights, indicator lights and au-
dible reminders” in the “Instruments and con-
trols” section of this manual.
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 the READY to drive position; it is
recommended that you contact an INFINITI re-
tailer. Even if the ignition switch is switched to the
READY to drive position, the system may shut off
suddenly. Therefore, drive cautiously to the near-
est 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) .
CAUTION
Do not start the system in N (Neutral)
position under cold condition of the sys-
tem. Start in the P (Park) position in that
case.
The READY to drive indicator light
flashes
until the hybrid system is ready to drive.
If starting in a low temperature environment, the
flashing time of the READY lamp becomes lon-
ger. It cannot move out from P (Park) 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.
EMERGENCY SHUT-OFF SYSTEM OPERATION OF THE HYBRID SYSTEM
HEV-4HEV Overview
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.
REGENERATIVE BRAKE EFFICIENT USE OF YOUR VEHICLE
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.
HIGH-VOLTAGE COMPONENTS
AND THEIR LOCATIONS
WARNING
●The INFINITI Direct Response Hybrid
System uses high voltage up to approxi-
mately 168 volts. The system can be hot
during and after starting. Be careful of
both the high voltage and the high tem-
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
can cause severe burns or electric
shock that may result in serious injury
or death.
