2014 INFINITI Q50 HYBRID ignition

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

WARNING
.Every person who drives or rides in this
vehicle should use a seat belt at all
times. Children should be properly re-
strained in the rear seat and, if appro-
priate, in a child restraint.
. The seat belt should be properly ad-
justed to a snug fit. Failure to do so may
reduce the effectiveness of the entire
restraint system and increase the chance
or severity of injury in an accident.
Serious injury or death can occur if the
seat belt is not worn properly.
. Always route the shoulder belt over your
shoulder and across your chest. Never
run the belt behind your back, under
your arm or across your neck. The belt
should be away from your face and neck,
but not falling off your shoulder.
. Position the lap belt as low and snug as
possible AROUND THE HIPS, NOT THE
WAIST. A lap belt worn too high could
increase the risk of internal injuries in an
accident.
. Be sure the seat belt tongue is securely
fastened to the proper buckle. .
Do not wear the seat belt inside out or
twisted. Doing so may reduce its effec-
tiveness.
. Do not allow more than one person to
use the same seat belt.
. Never carry more people in the vehicle
than there are seat belts.
. If the seat belt warning light glows
continuously while the ignition is turned
ON with all doors closed and all seat
belts fastened, it may indicate a mal-
function in the system. Have the system
checked by an INFINITI retailer.
. No changes should be made to the seat
belt system. For example, do not modify
the seat belt, add material or install
devices that may change the seat belt
routing or tension. Doing so may affect
the operation of the seat belt system.
Modifying or tampering with the seat
belt system may result in serious perso-
nal injury.
. Once a seat belt pretensioner has
activated, it cannot be reused and must
be replaced together with the retractor.
See an INFINITI retailer.

8. After attaching the child restraint, test
it before you place the child in it. Push
it from side to side while holding the
child restraint near the seat belt path.
The child restraint should not move
more than 1 inch (25 mm), from side to
side. Try to tug it forward and check to
see if the belt holds the restraint in
place. If the restraint is not secure,
tighten the seat belt as necessary, or
put the restraint in another seat and
test it again. You may need to try a
different child restraint. Not all child
restraints fit in all types of vehicles. 9. Check to make sure the child restraint
is properly secured prior to each use. If
the seat belt is not locked, repeat steps
2 through 8.

PRECAUTIONS ON SUPPLEMENTAL
RESTRAINT SYSTEM
This Supplemental Restraint System (SRS)
section contains important information
concerning 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 sup-
plemental 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 supple-
mental 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
collisions. The curtain air bags are de-
signed to inflate on the side where the
vehicle is impacted.
These supplemental restraint systems are
designed to
supplementthe crash protec-
tion provided by the driver and passenger
seat belts and are not a substitutefor
them. Seat belts should always be cor-
rectly worn and the occupant seated a
suitable distance away from the steering
wheel, instrument panel and door fin-
ishers. (See “Seat belts” (P.1-10) 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 warn-
ing light illuminates. The supplemental air
bag warning light will turn off after about
7 seconds if the systems are operational.
