2018 INFINITI Q50 HYBRID wheel

.Based on driving conditions.
. The shift lever is shifted to the P (Park)
position, the driver’s seat belt is re-
leased 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
DRIVING
The vehicle is driven by the electric motor
depending on the available Li-ion battery
charge.
MEDIUM OR HIGH SPEED DRIV-
ING
The system automatically controls the gaso-
line engine and electric motor in order to
obtain the optimum fuel mileage and per-
formance, 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.
RAPID ACCELERATION
The vehicle is accelerated using both the
gasoline engine and the electric motor
depending on the available Li-ion battery
charge.
DECELERATION AND BRAKING
The Li-ion battery is charged by the electric
motor that changes the energy of the
rotating wheels into electric power. See
“Regenerative brake” (P.Hybrid System-8).
STOPPING
The gasoline engine may stop running to
save fuel depending on the available Li-ion
battery charge. The INFINITI Direct Response Hybrid
®Sys-
tem monitors the status of power being sent
to the electric motor and the Lithium ion (Li-
ion) battery state of charge. The status is
shown on the assist charge gauge in the
meter and the energy flow/remaining Li-ion
battery charge in the lower display and the
meter. System status can also be shown
when the screen is in the energy flow mode
or energy/fuel history mode.

ASSIST CHARGE GAUGE
This gauge indicates the actual electric
motor power consumption and the charging
power to the Li-ion battery.
For additional information, see “Assist
charge gauge” (P.2-7).
ENERGY FLOW
When you use this system, make sure the
hybrid system is in the READY to drive mode.
See “Operation of the INFINITI Direct
Response Hybrid
®System” (P.Hybrid Sys-
tem-4).

All-Wheel Drive (AWD) models
If you use the system with the hybrid
system off (ignition switch placed in the
ACC position) for a long time, it will
discharge the 12-volt battery power, and
the hybrid system will not start.
Energy monitor for various operating modes
can be displayed in the lower display.
The energy flow is also displayed in the
vehicle information display. (See “1. Energy
monitor” (P.2-27).)
This is an example of the Energy Flow
display. The Energy Flow display changes,
depending on the following operating con-
ditions. The graphic indicates the amount of
power in the Li-ion battery. The following are displayed on the Energy
Flow screen.
.
When the vehicle is powered only by the
electric motor.
. When the vehicle is powered only by the
gasoline engine.
. When the vehicle is powered by both the
electric motor and the gasoline engine.
. When the vehicle is charging the Li-ion
battery with the regenerative brake and
gasoline engine.
. When the vehicle is charging the Li-ion
battery with the regenerative brake.
. When the vehicle is charging the Li-ion
battery with the gasoline engine.
. When the vehicle is powered by the
gasoline engine and is charging the Li-
ion battery.
. When there is no Energy Flow in the
vehicle
. When the vehicle is driving by the All-
Wheel Drive (AWD) (AWD models).

3. Current fuel consumption (Latest col- umn): The current fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption.
NOTE:
The fuel consumption displays on the upper
side of the fuel economy history display,
and the regenerated energy displays on the
lower side of the economy history. 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 follow-
ing 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 prop-
erly if the vehicle has tires and road wheels
other than the ones specified in this manual. Drive your vehicle with smooth acceleration
and deceleration.
.
While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for most
efficient use, do not accelerate or de-
celerate your vehicle more than neces-
sary.
. 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-6) or “Trip com-
puter” (P.2-27). Gradual or non-abrupt
acceleration and deceleration will make
more effective use of the electric power,
using less 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.

PRECAUTIONS ON SUPPLE-
MENTAL RESTRAINT SYSTEM
This Supplemental Restraint System (SRS)
section contains important information con-
cerning the following systems:
.Driver and passenger front-impact sup-
plemental air bags (INFINITI Advanced
Air Bag System)
. Front seat-mounted side-impact supple-
mental air bag
. Roof-mounted curtain side-impact and
rollover supplemental air bag
. Seat belt with pretensioner
Supplemental front-impact air bag system:
The INFINITI Advanced Air Bag System can
help cushion the impact force to the head
and chest of the driver and front passenger
in certain frontal collisions.
Front seat-mounted side-impact supple-
mental air bag system: This system can help
cushion the impact force to the chest and
pelvis area of the driver and front passenger
in certain side impact collisions. The side air
bag is designed to inflate on the side where
the vehicle is impacted.
Roof-mounted curtain side-impact and roll-
over supplemental air bag system: This
system can help cushion the impact force
to the head of occupants in front and rear
outboard seating positions in certain side impact or rollover collisions. In a side impact,
the curtain air bags are designed to inflate
on the side where the vehicle is impacted. In
a rollover, the curtain air bags on both sides
are designed to inflate and remain inflated
for a short time.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments may cause the curtain air bags to
inflate.
These supplemental restraint systems are
designed to
supplement the crash protection
provided by the driver and passenger seat
belts and are not a substitute for them. Seat
belts should always be correctly worn and
the occupant seated a suitable distance
away from the steering wheel, instrument
panel and door finishers. (See “Seat belts”
(P.1-9) for instructions and precautions on
seat belt usage.)
The supplemental air bags operate only
when the ignition switch is in the ON
position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the systems are operational.

WARNING
.The front air bags ordinarily will not
inflate in the event of a side impact,
rear impact, rollover, or lower sever-
ity frontal collision. Always wear
your seat belts to help reduce the
risk or severity of injury in various
kinds of accidents.
. The front passenger air bag will not
inflate if the passenger air bag status
light is lit. See “Front passenger air
bag and status light” (P.1-45).
. The seat belts and the front air bags
are most effective when you are
sitting well back and upright in the
seat with both feet on the floor. The
front air bags inflate with great
force. Even with the INFINITI Ad-
vanced Air Bag System, if you are
unrestrained, leaning forward, sitting
sideways or out of position in any
way, you are at greater risk of injury
or death in a crash. You may also
receive serious or fatal injuries from
the front air bag if you are up against
it when it inflates. Always sit back
against the seatback and as far-away
as practical from the steering wheel
or instrument panel. Always use the
seat belts.

.The driver and front passenger seat
belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The Advanced Air Bag
System monitors the severity of a
collision and seat belt usage then
inflates the air bags as needed. Fail-
ure to properly wear seat belts can
increase the risk or severity of injury
in an accident.
. The front passenger seat is equipped
with occupant classification sensors
(weight sensors) that turn the front
passenger air bag OFF under some
conditions. These sensors are only
used in this seat. Failure to be
properly seated and wearing the seat
belt can increase the risk or severity
of injury in an accident. See “Front
passenger air bag and status light”
(P.1-45).
. Keep hands on the outside of the
steering wheel. Placing them inside
the steering wheel rim could increase
the risk of injury if the front air bag
inflates.
