2014 INFINITI Q50-HYBRID batter

Hybrid System-10Hybrid System Overview
JVO0096X
1. Electric motor inverter
2. High voltage harnesses (orange)
3. Lithium ion (Li-ion) battery
4. Electric compressor
5. Electric motor6. 12-volt battery
The hybrid system uses high voltage up to
approximately 408 volts. High voltage
components are indicated in the illustra-
tion. High voltage harnesses are orange.
The system can be hot while and after
starting. Be careful of both the high voltageand the high temperature.
HYBRID VEHICLE 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 indicator
light is on even if the gasoline engine 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 accelerator
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 gradually. 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) battery may be da-
maged. If the Li-ion battery is completely
discharged and the hybrid system cannot be
activated, contact 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 ve-
hicles or home electronic appliances de-
spite 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
important. The vehicle cannot run if the Li-
ion battery is discharged. In the N (Neutral)
position, the Li-ion battery does not
recharge. Leaving the transmission 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).
JVO0100X
Left side
An air vent
*Ais located on the right and
left sides between the rear seat and rear
door to cool the Li-ion battery and DC/DC
converter. If the vent is covered, the Li-ion
battery or DC/DC converter will overheat
resulting in reduced output performance of
the hybrid system. See “Lithium-ion (Li-
ion) battery and DC/DC converter air vent”
(P.7-6).
JVO0101X
CAUTION
. Do not allow any liquid to get on or in
the air vent. It may cause a short circuit
and damage the Li-ion battery or DC/DC
converter.
. 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.
Noise and vibration
After the hybrid system is activated, the
following noises and vibrations that are
unique to the hybrid system may occur.
This does not indicate a malfunction..
Electric motor noise from the engine
compartment
. Noise from the rear of the vehicle when
the hybrid system activates or deacti-
vates
. Noise and vibration when the gasoline
engine starts running or stops
. Operating noise or electric motor noise
when releasing the accelerator pedal or
depressing the brake pedal
. Engine noise due to rapid acceleration
. Fan noise from the air inlet located
between the rear seat and rear door
. Noise from the climate control system
. Noise from the vehicle in order to alert
pedestrians to the presence of an
approaching vehicle. See “Approaching
Vehicle Sound for Pedestrians (VSP)
system” (P.Hybrid System-8).

WARNING AND INDICATOR LIGHTS

FRONT SEATS
Front power seat adjustment
Operating tips:
.The power seat motor has an auto-reset
overload protection circuit. If the motor
stops during operation, wait 30 sec-
onds, then reactivate the switch.
. Do not operate the power seat switch
for a long period of time when the
INFINITI Direct Response Hybrid
®Sys-
tem is not running. This will discharge
the 12-volt battery.
See “Automatic drive positioner” (P.3-28)
for the seat position memory function (if so
equipped).
SSS1051
Forward and backward:
Moving the switch
*1forward or backward
will slide the seat forward or backward to
the desired position.
Reclining:
Move the recline switch
*2backward until
the desired angle is obtained. To bring the
seatback forward again, move the switch
*2forward.
The reclining feature allows adjustment of
the seatback for occupants of different
sizes for added comfort and to help obtain
proper seat belt fit. (See “Precautions on
seat belt usage” (P.1-10).) Also, the seat- back can be reclined to allow occupants to
rest when the vehicle is parked.

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (RPM).Do not rev
the engine into the red zone
*1.
The scale length and the red zone vary with
the engine model.
CAUTION
When engine speed approaches the red
zone, shift to a higher gear or reduce engine
speed. Operating the engine in the red zone
may cause serious engine damage.

ASSIST CHARGE GAUGE
The gauge indicates the condition of the
electric motor.
When the needle is between the center and
“charge”
*1side, this indicates that
the electric motor is generating power to
recharge the Li-ion battery.
When the needle is between the center and
the PWR
*2side, this indicates that the
electric motor is powering the drive wheels
and the Li-ion battery is discharging.
JVI0640X
FUEL GAUGE
The gauge indicates the approximatefuel
level in the tank.
The gauge may move slightly during
braking, turning, acceleration, or going up
or down hills.
The gauge needle returns to “0”(Empty)
after the ignition switch is pushed to the
OFF position.
Refill the fuel tank before the gauge
registers “0”(Empty).
The low fuel warning light
illuminates
on the meter when the fuel level is getting
low. Refuel as soon as it is convenient,
