WARNING
●The INFINITI Direct Response Hybrid®
System uses high voltage up to approxi-
mately 144volts. 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 and harnesses as
well as their connectors can cause se-
vere 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. Take your ve-
hicle to an INFINITI retailer for any nec-
essary maintenance.
● Never try to remove the service plug
located in the trunk. 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. Touching the ser-
vice 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 electric mo-
tor inverter and Li-ion battery. An elec-
tric shock may occur if exposed electric
wires are visible when viewed from in-
side or outside of your vehicle. There-
fore, 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 1st
responders that this is a hybrid vehicle.

gent Key if the vehicle has remote engine start.
This feature allows the engine to start from out-
side the vehicle.
The following features may be affected when the
remote start feature is used:
● Vehicles with an automatic climate control
system will default to either a heating or
cooling mode depending on the outside
temperature.
● Vehicles without automatic climate control
will default to the last used heating or cool-
ing mode. ●
Vehicles equipped with heated seats may
have this feature come on during a remote
start. For additional information, refer to
“Heated front seats” in the “Instruments and
controls” section of this manual.
Laws in some local communities may restrict the
use of remote starters. For example, some laws
require a person using remote start to have the
vehicle in view. Check local regulations for any
requirements.
Other conditions may affect the function of the
Remote Engine Start feature. For additional infor-
mation, refer to “Conditions the remote start will
not work” in this section.

Pre-driving checks and adjustments3-19
Reception conditions will constantly change be-
cause of vehicle movement. Buildings, terrain,
signal distance and interference from other ve-
hicles can work against ideal reception. De-
scribed below are some of the factors that can
affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the de-
vice in a different location may reduce or elimi-
nate the noise.
FM RADIO RECEPTION
Range: FM range is normally limited to 25 – 30 mi
(40 – 48 km) , with monaural (single channel) FM
having slightly more range than stereo FM. Exter-
nal influences may sometimes interfere with FM
station reception even if the FM station is within
25 mi (40 km) . The strength of the FM signal is
directly related to the distance between the
transmitter and receiver. FM signals follow a line-
of-sight path, exhibiting many of the same char-
acteristics as light. For example, they will reflect
off objects.
Fade and drift: As your vehicle moves away from
a station transmitter, the signals will tend to fade
and/or drift.Static and flutter: During signal interference from
buildings, large hills or due to antenna position
(usually in conjunction with increased distance
from the station transmitter) , static or flutter can
be heard. This can be reduced by adjusting the
treble control to reduce treble response.
Multipath reception: Because of the reflective
characteristics of FM signals, direct and reflected
signals reach the receiver at the same time. The
signals may cancel each other, resulting in mo-
mentary flutter or loss of sound.
AM RADIO RECEPTION
AM signals, because of their low frequency, can
bend around objects and skip along the ground.
In addition, the signals can be bounced off the
ionosphere and bent back to earth. Because of
these characteristics, AM signals are also sub-
ject to interference as they travel from transmitter
to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas with
many tall buildings. It can also occur for several
seconds during ionospheric turbulence even in
areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic lights.
SATELLITE RADIO RECEPTION
When the satellite radio is used for the first time
or the battery has been replaced, the satellite
radio may not work properly. This is not a mal-
function. Wait more than 10 minutes with satellite
radio ON and the vehicle outside of any metal or
large building for satellite radio to receive all of
the necessary data.
The satellite radio mode will be skipped unless an
optional satellite receiver and antenna are in-
stalled and a SiriusXM® Satellite Radio service
subscription is active. Satellite radio is not avail-
able in Alaska, Hawaii and Guam.
Satellite radio performance may be affected if
cargo carried on the roof blocks the satellite radio
signal.
If possible, do not put cargo over the satellite
antenna.
A build up of ice on the satellite radio antenna can
affect satellite radio performance. Remove the
ice to restore satellite radio reception.
