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.
See “Approaching Vehicle Sound for Pedestri-
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.
HIGH-VOLTAGE COMPONENTS
AND THEIR LOCATIONS
WARNING
● The INFINITI Direct Response Hybrid®
System uses high voltage up to approxi-
mately 144 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.

CHARACTERISTICS
WARNING
●When you leave your vehicle, be sure to
place the ignition switch in the OFF
position.
● Be sure to put the transmission in the P
(Park) position because the vehicle can
move when the READY to drive indica-
tor light is on even if the gasoline en-
gine is not running. When the READY to
drive indicator light is on, do not leave
your vehicle in a shift position other
than the P (Park) position. The vehicle
will creep and start abruptly if the accel-
erator pedal is depressed by mistake.
This may cause serious injury or death.

CAUTION
●If the vehicle is parked for a long period
of time, the battery discharges gradu-
ally. To avoid this occurrence, drive the
vehicle for approximately 30 minutes at
least once every two to three months.
Otherwise, the Lithium ion (Li-ion) bat-
tery may be damaged. If the Li-ion bat-
tery is completely discharged and the
hybrid system cannot be activated, con-
tact an INFINITI retailer.
High-voltage parts and harnesses on the hybrid
vehicles emit approximately the same amount of
electromagnetic waves as the conventional
gasoline-powered vehicles or home electronic
appliances despite of their electromagnetic
shieldings. Unwanted noise may occur in the
reception of a mobile two-way radio.
Charging the Li-ion battery while driving is impor-
tant. The vehicle cannot run if the Liion battery is
discharged. In the N (Neutral) position, the Li-ion
battery does not recharge. Leaving the transmis-
sion in the N (Neutral) position for an extended
period of time may discharge the Li-ion battery.
The Li-ion battery recharges when the shift lever
is in any position other than N (Neutral) . An air vent is located on the rear side trim panels
Ato cool the high-voltage battery. If the vent is
covered, the battery will overheat resulting in
reduced output performance of the hybrid sys-
tem. See “Lithium-ion (Li-ion) battery air vent” in
the “Appearance and care” section.
You may hear the noise of the cooling fan from the
air vent.
CAUTION
Do not place objects over or into the air
vent. The Li-ion battery or DC/DC con-
verter may overheat and be damaged.
CAUTION
Do not load large amounts of water in
open containers (aquariums or buckets)
into the vehicle. If the water spills onto the
Li-ion battery, it may cause a short circuit
and damage the battery.
CAUTION
It may cause a short circuit and damage
the 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 accelerationLPD2173

●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
vehicle. See “Approaching Vehicle Sound
for Pedestrians (VSP) system” in this sec-
tion.
