2014 INFINITI Q50 HYBRID ECO mode

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 System-8Hybrid System Overview
When the vehicle decelerates while the
vehicle is driven with the shift lever in the
D (Drive) position or in the manual shift
mode, the Lithium ion (Li-ion) battery can
be charged by the electric motor. The
electric motor converts the energy of the
rotating wheels into electric power under
the following circumstances:
.When the accelerator pedal is released.
. When the brake pedal is depressed.
. When there is no malfunction in the
brake system or the INFINITI Direct
Response Hybrid
®System.
The regenerative brake may not work
properly if the vehicle has tires and road
wheels other than the ones specified in
this manual. Drive your vehicle with smooth accelera-
tion and deceleration.
.
While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for most
efficient use, do not accelerate or
decelerate your vehicle more than
necessary.
. Avoid abrupt acceleration and decelera-
tion.
. The power of the Lithium ion (Li-ion)
battery can be checked on the Energy
Flow or Energy monitor. See “Energy
Flow” (P.Hybrid System-5) or “Trip
computer” (P.2-31). Gradual or non-
abrupt acceleration and deceleration
will make more effective use of the
electric using gasoline engine power.
. When parking, be sure to place the shift
lever in the P (Park) position. While
driving, place the shift lever in the D
(Drive) position. The Approaching Vehicle Sound for Pedes-
trians (VSP) system is a function that uses
sound to help alert pedestrians of the
presence of the vehicle when it is being
driven at a low speed in the electric drive
mode under the following conditions:
.
The sound starts when the vehicle
starts accelerating.
. The sound stops when the vehicle
speed is more than 19 MPH (30 km/h)
while accelerating.
. The sound starts when the vehicle
speed is less than 16 MPH (25 km/h)
while decelerating.
. The sound stops when the vehicle
stops.
. The sound does not stop with the
vehicle in the R (Reverse) position even
if the vehicle stops.
The VSP system is automatically turned on
when the vehicle is in the READY to drive
mode.
If there is a malfunction in the VSP system,
the VSP OFF indicator light in the meter
illuminates. See “Approaching Vehicle
Sound for Pedestrians (VSP) OFF indicator
light” (P.2-18).

not be able to retract the seat belt. After a
few minutes, the motor reactivates and
retracts the seat belt. If the seat belt still
cannot be retracted by the motor, the pre-
crash seat belt system has a malfunction.
Have your INFINITI retailer check and repair
the system.
THREE-POINT TYPE SEAT BELT
WARNING
.Every person who drives or rides in this
vehicle should use a seat belt at all
times.
. Do not ride in a moving vehicle when the
seatback is reclined. This can be danger-
ous. The shoulder belt will not be
against your body. In an accident, you
could be thrown into it and receive neck
or other serious injuries. You could also
slide under the lap belt and receive
serious internal injuries.
. For the most effective protection when
the vehicle is in motion, the seat should
be upright. Always sit well back in the
seat with both feet on the floor and
adjust the seat belt properly. .
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes tight.
This can occur even if the vehicle is
parked. Unbuckle the seat belt to release
the child. If the seat belt can not be
unbuckled or is already unbuckled,
release the child by cutting the seat belt
with a suitable tool (such as a knife or
scissors) to release the seat belt.SSS0292
Fastening the seat belts
1. Adjust the seat. (See “Seats”(P.1-2).)
2. Slowly pull the seat belt out of the retractor and insert the tongue into the
buckle until you hear and feel the latch
engage.
.The retractor is designed to lockduring a sudden stop or on impact.
A slow pulling motion permits the
belt to move, and allows you some
freedom of movement in the seat.
.If the seat belt cannot be pulledfrom its fully retracted position,
firmly pull the belt and release it.

belts may retract slowly. Wipe the
shoulder belt guide with a clean, dry
cloth.
. Periodically check to see that the seat
belt and the metal components such as
buckles, tongues, retractors, flexible
wires and anchors work properly. If
loose parts, deterioration, cuts or other
damage on the webbing is found, the
entire seat belt assembly should be
replaced.WARNING
Do not allow children to play with the seat
belts. Most seating positions are equipped
with Automatic Locking Retractor (ALR)
mode seat belts. If the seat belt becomes
wrapped around a child’s neck with the ALR
mode activated, the child can be seriously
injured or killed if the seat belt retracts and
becomes tight. This can occur even if the
vehicle is parked. Unbuckle the seat belt to
release the child. If the seat belt can not be
unbuckled or is already unbuckled, release
the child by cutting the seat belt with a
suitable tool (such as a knife or scissors) to
release the seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in
this manual, child safety information is
available from many other sources, includ-
ing doctors, teachers, government traffic
safety offices, and community organiza-
tions. Every child is different, so be sure to
learn the best way to transport your child.
There are three basic types of child
restraint systems: .
Rear-facing child restraint
. Forward-facing child restraint
. Booster seat
The proper restraint depends on the child’s
size. Generally, infants up to about 1 year
and less than 20 lbs (9 kg) should be
placed in rear-facing child restraints. For-
ward-facing child restraints are available
for children who outgrow rear-facing child
restraints and are at least 1 year old.
Booster seats are used to help position a
vehicle lap/shoulder belt on a child who
can no longer use a forward-facing child
restraint.
WARNING
Infants and children need special protection.
The vehicle’s seat belts may not fit them
properly. The shoulder belt may come too
close to the face or neck. The lap belt may
not fit over their small hip bones. In an
accident, an improperly fitting seat belt
could cause serious or fatal injury. Always
use appropriate child restraints.
All U.S. states and Canadian provinces or
territories require the use of approved
child restraints for infants and small

operated under some conditions as de-
scribed below as permitted by U.S. regula-
tions. If the front passenger air bag is OFF,
it will not inflate in a crash. The driver air
bag and other air bags in your vehicle are
not part of this system.
The purpose of the regulation is to help
reduce the risk of injury or death from an
inflating air bag to certain front passenger
seat occupants, such as children, by
requiring the air bag to be automatically
turned OFF.
The occupant classification sensors
(weight sensors) are on the seat cushion
frame under the front passenger seat and
are designed to detect an occupant and
objects on the seat. For example, if a child
is in the front passenger seat, the Ad-
vanced Air Bag System is designed to turn
the passenger air bag OFF in accordance
with the regulations. Also, if a child
restraint of the type specified in the
regulations is on the seat, the occupant
classification sensor can detect it and
cause the air bag to turn OFF.
Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined in this manual should not
cause the passenger air bag to be auto-matically turned OFF. For small adults it
may be turned OFF, however, if the
occupant does not sit in the seat properly
(for example, by not sitting upright, by
sitting on an edge of the seat, or by
otherwise being out of position), this could
cause the sensor to turn the air bag OFF.
Always be sure to be seated and wearing
the seat belt properly for the most effective
protection by the seat belt and supple-
mental air bag.
INFINITI recommends that pre-teens and
children be properly restrained in a rear
seat. INFINITI also recommends that appro-
priate child restraints and booster seats be
properly installed in a rear seat. If this is
not possible, the occupant classification
sensors are designed to operate as de-
scribed above to turn the front passenger
air bag OFF for specified child restraints.
Failing to properly secure child restraints
and to use the ALR mode (child restraint
mode) may allow the restraint to tip or
move in an accident or sudden stop. This
can also result in the passenger air bag
inflating in a crash instead of being OFF.
(See
“Child restraints” (P.1-19) for proper
use and installation.)
If the front passenger seat is not occupied, the passenger air bag is designed not to
inflate in a crash. However, heavy objects
placed on the seat could result in air bag
inflation, because of the object being
detected by the occupant classification
sensor. Other conditions could also result
in air bag inflation, such as if a child is
standing on the seat, or if two children are
on the seat, contrary to the instructions in
this manual. Always be sure that you and
all vehicle occupants are seated and
restrained properly.
Using the passenger air bag status light,
you can monitor when the front passenger
air bag is automatically turned OFF with the
seat occupied. The light will not illuminate
when the front passenger seat is unoccu-
pied.
If an adult occupant is in the seat but the
passenger air bag status light is illumi-
nated (indicating that the air bag is OFF), it
could be that the person is a small adult,
or is not sitting on the seat properly.
If a child restraint must be used in the front
seat, the passenger air bag status light
may or may not be illuminated, depending
on the size of the child and the type of
child restraint being used. If the passenger
air bag status light is not illuminated

pretensioner seat belt will not operate in an
accident. To help avoid injury to yourself or
others, have your vehicle checked by a
retailer as soon as possible.
Vehicle Dynamic Control (VDC)
warning light
The light will blink when the Vehicle
Dynamic Control (VDC) system or the

alerting the driver that the vehicle is
nearing its traction limits. The road surface
may be slippery.
When the VDC warning light illuminates
when the VDC system is turned on, this
light alerts the driver to the fact that the
VDC system’s fail-safe mode is operating,
for example the VDC, active trace control,
rise-up and build-up function, brake force
distribution or hill start assist system may
not be functioning properly. Have the
system checked by an INFINITI retailer. If
a malfunction occurs in the system, the
VDC system function will be canceled but
the vehicle is still driveable. For additional
information, see “Vehicle Dynamic Control
