2018 INFINITI Q70-HYBRID engine

Hybrid System-10Hybrid System Overview
JVO0011X
1. Electric motor inverter
2. High voltage harnesses (orange)
3. Lithium ion (Li-ion) battery
4. DC/DC converter
5. Service plug
6. Electric compressor7. Electric motor
8. 12-volt battery
The hybrid system uses high voltage up to
approximately 408 volts. High voltage com-
ponents are indicated in the illustration. High
voltage harnesses are orange. The system
can be hot while and after starting. Becareful of both the high voltage and the
high temperature.

ISTICS
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 gaso-
line 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 gradu-
ally. To avoid this occurrence, drive the

CAUTION
Do not place objects over or into the air
vent. The Li-ion battery may overheat
and be damaged.
JVO0006X
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.
JVO0020X
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.
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 on the
rear parcel shelf
. Noise from the climate control system
. Noise from the vehicle in order to alert
pedestrians to the presence of an ap-
proaching vehicle. See “Approaching Ve-
hicle Sound for Pedestrians (VSP)
system” (P.Hybrid System-8).

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (RPM).Do not rev
the engine into the red zone
.
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.
JVI0197X
ASSIST CHARGE GAUGE
The gauge indicates the condition of the
electric motor.
When the needle is between the center and
the PWR
side, this indicates that the
electric motor is powering the drive wheels
and the Lithium-ion (Li-ion) battery is dis-
charging.
When the needle is between the center and
CHG
side, this indicates that the electric
motor is generating power to recharge the
Li-ion battery.
JVI0846X
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
appears on the
vehicle information display when the fuel
level is getting low. Refuel as soon as it is
convenient, preferably before the gauge
