2014 INFINITI Q50 HYBRID transmission

Hybrid System-4Hybrid System Overview
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
“Warning/indicator lights and audible re-
minders” (P.2-12).
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
switch to READY to drive position, contact
an INFINITI retailer. Even if the ignition
switch is switched to READY to drive
position, the system may shut-off sud-
denly. 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.5-10).)
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
automatically. 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.
. Based on driving conditions.
. The shift lever is shifted to the P (Park)
position, the driver’ s seat belt is
released and the driver’s side door is
then opened.
The hybrid system operates as follows
based on driving conditions and the Li-ion
battery charge.
STARTING AND SLOW SPEED DRIV-
ING
The vehicle is driven by the electric motor
depending on the available Li-ion battery
charge.
MEDIUM OR HIGH SPEED DRIVING
The system automatically controls the
gasoline engine and electric motor in order
to obtain the optimum fuel mileage and
performance, depending on the driving
situation and available Li-ion battery
charge.
When the remaining battery level is low,
the Li-ion battery is charged by the electric
motor that is driven to generate electric
power while the vehicle is driving.

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.

PROGRAMMING HomeLink®FOR
CANADIAN CUSTOMERS AND GATE
OPENERS
Canadian radio-frequency laws require
transmitter signals to “time-out”(or quit)
after several seconds of transmission –
which may not be long enough for
HomeLink
®to pick up the signal during
programming. Similar to this Canadian
law, some U.S. gate operators are de-
signed to “time-out” in the same manner.
If you live in Canada or you are having
difficulties programming a gate operator or
garage door opener by using the “Pro-
gramming HomeLink
®” procedures, re-
place “Programming HomeLink®”Step 2
with the following:
NOTE:
When programming a garage door opener,
etc., unplug the device during the “cy-
cling” process to prevent possible damage
to the garage door opener components.
Step 2: Using both hands, simultaneously
press and hold the desired HomeLink
®
button and the hand-held transmitter
