WARNING
●The INFINITI Direct Response Hybrid
System uses high voltage up to approxi-
mately 168 volts. The system can be hot
while 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 disassemble, remove or replace
high-voltage parts, harnesses and their
connectors. Touching, disassembling,
removing or replacing those parts and
harnesses can cause severe burns or
electric shock that may result in serious
injury or death. High-voltage harnesses
are colored orange. The vehicle high-
voltage system has no user serviceable
parts. It is recommended that you take
your vehicle to an INFINITI retailer for
any necessary maintenance.
● Never try to remove the service plug
located in the cargo area. The service
plug is used only when the vehicle is
serviced by trained technicians wearing
personal protection equipment and is
part of the high-voltage system. Touch-
ing the service plug can cause severe
burns or electric shock that may result
in serious injury or death.
WARNING
In case of a collision:
● If your vehicle is drivable, pull your ve-
hicle off the road, put the transmission
in the P (Park) position, apply the park-
ing brake and turn the INFINITI Direct
Response Hybrid System off.
● Check to see if there are exposed high-
voltage parts and cables. Never touch
the parts and cables. For their locations,
refer to “High-voltage components and
their locations” in this section. To avoid
personal injury, never touch high-
voltage wiring, connectors, and other
high-voltage parts, such as the electric
motor inverter and Li-ion battery. An
electric shock may occur if exposed
electric wires are visible when viewed
from inside or outside of your vehicle.
Therefore, never touch exposed electric
wires.
● If the vehicle receives a strong impact to
the floor while driving, stop the vehicle
in a safe location and check the floor.
● Inspect the ground under the vehicle. If
liquid has leaked onto the ground, the
fuel system may have been damaged.
Leave the vehicle as soon as possible. ●
Leaks or damage to the Li-ion battery
may result in a fire. If you discover them,
contact emergency services immedi-
ately. Since the fluid leak may be
lithium organic electrolyte from the Li-
ion battery, never touch the fluid leak
inside or outside the vehicle. If the fluid
contacts your skin or eyes, wash it off
immediately with a large amount of wa-
ter and receive immediate medical at-
tention to help avoid serious injury.
● If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Only use a type ABC, BC or C fire extin-
guisher that is meant for use on electri-
cal fires. Using water or the incorrect
fire extinguisher can result in serious
injury or death from electrical shock.
● If you are not able to safely assess the
vehicle due to vehicle damage, do not
touch the vehicle. Leave the vehicle and
contact emergency services. Advise first
responders that this is a hybrid vehicle.
HIGH-VOLTAGE CAUTIONS ROAD ACCIDENT CAUTIONS
HEV OverviewHEV-3
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 display in the
center display (models with navigation sys-
tem) or Li-ion battery status meter in the
vehicle information display. For additional
information, refer to “Energy Flow (models
with navigation system)” in this section or
“Trip computer” in the “Instruments and con-
trols” 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. 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.

2-28Instruments and controls
WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
● The Intelligent Key transmits radio
waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraft navigation and communi-
cation systems. Do not operate the In-
telligent Key while on an airplane. Make
sure the buttons are not operated unin-
tentionally when the unit is stored for a
flight.
The Intelligent Key system can operate all the
door locks using the remote control function or
pushing the request switch on the vehicle without
taking the key out from a pocket or purse. The
operating environment and/or conditions may af-
fect the Intelligent Key system operation.
Be sure to read the following before using the
Intelligent Key system.
CAUTION
● Be sure to carry the Intelligent Key with
you when operating the vehicle.
● Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicating with
the vehicle as it receives radio waves. The Intel-
ligent Key system transmits weak radio waves.
Environmental conditions may interfere with the
operation of the Intelligent Key system under the
following operating conditions: ● When operating near a location where
strong radio waves are transmitted, such as
a TV tower, power station and broadcasting
station.
● When in possession of wireless equipment,
such as a cellular telephone, transceiver or a
CB radio.
● When the Intelligent Key is in contact with or
covered by metallic materials.
● When any type of radio wave remote control
is used nearby.
● When the Intelligent Key is placed near an
electric appliance such as a personal com-
puter. ●
When the vehicle is parked near a parking
meter.
In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depending
on the operating conditions, the battery’s life is
approximately two years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is low, an indi-
cator illuminates in the vehicle information dis-
play. For additional information, refer to “Vehicle
information display” in the “Instruments and con-
trols” section of this manual.
Since the Intelligent Key is continuously receiving
radio waves, if the key is left near equipment
which transmits strong radio waves, such as sig-
nals from a TV and personal computer, the bat-
tery life may become shorter.
For additional information, refer to “Battery re-
placement” in the “Do-it-yourself” section of this
manual.
As many as four Intelligent Keys can be regis-
tered and used with one vehicle. For information
about the purchase and use of additional Intelli-
gent Keys, it is recommended that you visit an
INFINITI retailer.
INFINITI INTELLIGENT KEY SYSTEM
Pre-driving checks and adjustments3-7
When the Intelligent Key battery is discharged or
strong radio waves are present near the operat-
ing location, the Intelligent Key operating range
becomes narrower, and the Intelligent Key may
not function properly.
The operating range is within 31.5 in (80 cm)
from each request switch
