2018 INFINITI Q70-HYBRID transmission

Hybrid System-4Hybrid System Overview
delivered to an INFINITI retailer to
have the Li-ion battery pack and high
voltage parts such as the inverter,
including the wiring harness, re-
moved prior to painting. Li-ion bat-
tery packs exposed to heat in the
paint booth will experience capacity
loss. Damaged Li-ion battery packs
may also pose safety risks to un-
trained mechanics and repair person-
nel.The emergency shut-off system is activated
and the high-voltage system automatically
turns off in the following conditions:
.
Front and side collisions in which the air
bags are deployed.
. Certain rear collisions.
. Certain INFINITI Direct Response Hy-
brid
®System malfunctions
For the above collisions and the certain
hybrid system malfunctions, the READY to
drive indicator light will turn off. See “Warn-
ing lights, indicator lights and audible re-
minders” (P.2-10).
The emergency shut-off activates for the
above collisions to minimize risk of an event
that could cause injury or an accident. If the
emergency shut-off system activates, the
hybrid system may not switched to READY
to drive position, it is recommended that you
contact an INFINITI retailer. Even if the
ignition switch is switched to READY to
drive position, the system may shut-off
suddenly. Therefore, drive cautiously to the
nearest INFINITI retailer or contact an
INFINITI retailer as soon as possible. To start the INFINITI Direct Response
Hybrid
®System:
1. Depress the brake pedal and place the ignition switch in the ON position when
the transmission is in the P (Park) or N
(Neutral) position (P is recommended).
(For more details, see “Push-button
ignition switch” (P.5-9).)
2. The READY to drive indicator light
flashes, then turns illuminated. (The
hybrid system switched to the READY
to drive mode when the indicator light
illuminates.)
When the READY to drive indicator light
illuminates, the vehicle can be driven, even if
the gasoline engine is not running.
NOTE:
The gasoline engine starts and stops auto-
matically. It may stop during low speed
driving, deceleration or when the vehicle is
stopped.
The gasoline engine may automatically run
in the following conditions:
. The level of remaining charge in the
Lithium ion (Li-ion) battery is low. The
engine runs to charge the Li-ion battery
and to provide power to the drive the
vehicle.
. The temperature of the engine coolant is
low.

HYBRID VEHICLE CHARACTER-
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

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
battery is completely discharged and
the hybrid system cannot be activated,
it is recommended that you 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 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
important. The vehicle cannot run if the Li-
ion battery is discharged. When in the N
(Neutral), D (Drive) or R (Reverse) position,
and while the accelerator pedal or the brake
pedal is not depressed, the Li-ion battery
does not recharge. Leaving the transmission
in the N (Neutral), D (Drive) or R (Reverse)
position, and while the accelerator pedal or
the brake pedal is not depressed for an
extended period of time (for example, when
the shift lever is in the D (Drive) position and
the vehicle is stopped only by the parking
brake), may discharge the Li-ion battery and
the hybrid system may automatically be turned off.
JVO0019X
An air ventis located on the rear parcel
shelf to cool the Li-ion battery. If the vent is
covered, the battery will overheat resulting
in reduced output performance of the hybrid
system. See “Lithium-ion (Li-ion) battery air
vent” (P.7-5).
