2014 INFINITI Q50 HYBRID wiring

WARNING
In case of a collision:
.If your vehicle is drivable, pull your
vehicle off the road, put the transmis-
sion in the P (Park) position, apply the
parking brake and turn the INFINITI
Direct Response Hybrid
®System off.
. Check to see if there are exposed high
voltage parts and cables. Never touch
the parts and cables. For their locations,
see “High voltage components” (P.Hy-
brid System-9). To avoid personal injury,
never touch high-voltage wiring, con-
nectors, and other high-voltage parts,
such as electric motor inverter and
Lithium ion (Li-ion) battery. An electric
shock may occur if exposed electric
wires are visible when viewed from
inside or outside of your vehicle. There-
fore, never touch exposed electric wires.
. If the vehicle receives a strong impact to
the floor while driving, stop the vehicle
in a safe location and check the floor.
. Inspect the ground under the vehicle. If
liquid has leaked onto the ground, the
fuel system may have been damaged. Leave the vehicle as soon as possible.
. Leaks or damage to the Li-ion battery
may result in a fire. If you discover them,
contact emergency services immedi-
ately. Since the fluid leak may be lithium
organic electrolyte from the Li-ion bat-
tery, never touch the fluid leak inside or
outside the vehicle. If the fluid contacts
your skin or eyes, wash it off immedi-
ately with a large amount of water and
receive immediate medical attention to
help avoid serious injury.
. If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Only use a type ABC, BC or C fire
extinguisher that is meant for use on
electrical fires. Using water or the
incorrect fire extinguisher can result in
serious injury or death from electrical
shock.
. If you are not able to safely assess the
vehicle due to vehicle damage, do not
touch the vehicle. Leave the vehicle and
contact emergency services. Advise 1st
responders that this is a hybrid vehicle.
. In the event of an accident that requires
body repair and painting, the vehicle
should be delivered to an INFINITI retailer to have the Li-ion battery pack
and high voltage parts such as the
inverter, including the wiring harness,
removed prior to painting. Li-ion battery
packs exposed to heat in the paint booth
will experience capacity loss. Damaged
Li-ion battery packs may also pose
safety risks to untrained mechanics
and repair personnel.

ROAD ACCIDENT CAUTIONS

1-46Safety—Seats, seat belts and supplemental restraint system
(indicating that the air bag might inflate in
a crash), it could be that the child restraint
or seat belt is not being used properly.
Make sure that the child restraint is
installed properly, the seat belt is used
properly and the occupant is positioned
properly. If the passenger air bag status
light is still not illuminated, reposition the
occupant or child restraint in a rear seat.
If the passenger air bag status light will not
illuminate even though you believe that the
child restraint, the seat belts and the
occupant are properly positioned, the
system may be sensing an unoccupied
seat (in which case the air bag is OFF). Your
INFINITI retailer can check that the system
is OFF by using a special tool. However,
until you have confirmed with your retailer
that your air bag is working properly,
reposition the occupant or child restraint
in a rear seat.
The INFINITI Advanced Air Bag System and
passenger air bag status light will take a
few seconds to register a change in the
passenger seat status. However, if the seat
becomes unoccupied, the air bag status
light will remain off.
If a malfunction occurs in the front
passenger air bag system, the supplemen- tal air bag warning light, located in the
meter and gauges area will blink. Have the
system checked by an INFINITI retailer.
Other supplemental front-impact
air bag precautions
WARNING
. Do not place any objects on the steering
wheel pad or on the instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may
become dangerous projectiles and cause
injury if the front air bags inflate.
. Do not place objects with sharp edges
on the seat. Also, do not place heavy
objects on the seat that will leave
permanent impressions in the seat. Such
objects can damage the seat or occupant
classification sensors (weight sensors).
This can affect the operation of the air
bag system and result in serious perso-
nal injury.
. Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion sensors. This can also affect the operation of the air bag system and
result in serious personal injury.
. Immediately after inflation, several front
air bag system components will be hot.
Do not touch them; you may severely
burn yourself.
. No unauthorized changes should be
made to any components or wiring of
the air bag system. This is to prevent
accidental inflation of the supplemental
air bag or damage to the supplemental
air bag system.
. Do not make unauthorized changes to
your vehicle’s electrical system, suspen-
sion system or front end structure. This
could affect proper operation of the front
air bag system.
. Tampering with the air bag system may
result in serious personal injury. Tamper-
ing includes changes to the steering
wheel and the instrument panel assem-
bly by placing material over the steering
wheel pad and above the instrument
panel or by installing additional trim
material around the air bag system.
. Removing or modifying the front pas-
senger seat may affect the function of
the air bag system and result in serious

personal injury.
. Modifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing
material on the seat cushion or by
installing additional trim material, such
as seat covers, on the seat that is not
specifically designed to assure proper
air bag operation. Additionally, do not
stow any objects under the front pas-
senger seat or the seat cushion and
seatback. Such objects may interfere
with the proper operation of the occu-
pant classification sensors.
. No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect the
front air bag system. Tampering with the
seat belt system may result in serious
personal injury.
. Work on and around the front air bag
system should be done by an INFINITI
retailer. Installation of electrical equip-
ment should also be done by an INFINITI
retailer. The Supplemental Restraint
System (SRS) wiring harnesses* should
not be modified or disconnected. Un-
authorized electrical test equipment and probing devices should not be used on
the air bag system.
. A cracked windshield should be replaced
immediately by a qualified repair facility.
A cracked windshield could affect the
function of the supplemental air bag
system.
* The SRS wiring harness connectors
are yellow and orange for easy
identification.
When selling your vehicle, we request that
you inform the buyer about the front air
bag system and guide the buyer to the
appropriate sections in this Owner’s Man-
ual.

FRONT SEAT-MOUNTED SIDE-IM-
PACT SUPPLEMENTAL AIR BAG AND
ROOF-MOUNTED CURTAIN SIDE-IM-
PACT SUPPLEMENTAL AIR BAG SYS-
TEMS
The side air bags are located in the outside
of the seatback of the front seats. The
curtain air bags are located in the side roof
rails. However, all of the information,
cautions and warnings in this manual still
apply and must be followed. The side air
bags and curtain air bags are designed to
inflate in higher severity side collisions,
although they may inflate if the forces in
Safety —Seats, seat belts and supplemental restraint system1-47

1-48Safety—Seats, seat belts and supplemental restraint system
another type of collision are similar to
those of a higher severity side impact. They
are designed to inflate on the side where
the vehicle is impacted. They may not
inflate in certain side collisions on the side
where the vehicle is impacted.
Vehicle damage (or lack of it) is not always
an indication of proper supplemental side
air bag and curtain side-impact air bag
operation.
When side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by release of smoke. This smoke
is not harmful and does not indicate a fire.
Care should be taken not to inhale it, as it
may cause irritation and choking. Those
with a history of a breathing condition
should get fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on
the chest and pelvis of the front occupants.
Curtain air bags help to cushion the impact
force to the head of occupants in the front
and rear outboard seating positions. They
can help save lives and reduce serious
injuries. However, an inflating side air bags
and curtain air bags may cause abrasions
or other injuries. Side air bags and curtain
air bags do not provide restraint to the lower body.
The seat belts should be correctly worn
and the driver and passenger seated
upright as far as practical away from the
side air bag. Rear seat passengers should
be seated as far away as practical from the
door finishers and side roof rails. The side
air bags and curtain air bags inflate quickly
in order to help protect the occupants.
Because of this, the force of the side air
bags and curtain air bags inflating can
increase the risk of injury if the occupant is
too close to, or is against, these air bag
modules during inflation. The side air bags
and curtain air bags will deflate quickly
after the collision is over.
The side air bags and curtain 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 air bag warning
light will turn off after about 7 seconds if
the systems are operational.
WARNING
.
Do not place any objects near the
seatback of the front seats. Also, do
not place any objects (an umbrella, bag,
etc.) between the front door finisher and
the front seat. Such objects may become
dangerous projectiles and cause injury if
side air bag inflates.
. Right after inflation, several side air
bags and curtain air bag system compo-
nents will be hot. Do not touch them;
you may severely burn yourself.
. No unauthorized changes should be
made to any components or wiring of
side air bag and curtain air bags. This is
to prevent damage to or accidental
inflation of the side air bag and curtain
air bag systems.
. Do not make unauthorized changes to
your vehicle’s electrical system, suspen-
sion system or side panel. This could
affect proper operation of the side air
bag and curtain air bag systems.
. Tampering with the air bag system may
result in serious personal injury. For
example, do not change the front seats
by placing material near the seatback or

by installing additional trim material,
such as seat covers, around the side air
bags.
. Work around and on the side air bag and
curtain air bag systems should be done
by an INFINITI retailer. Installation of
electrical equipment should also be
done by an INFINITI retailer. The Supple-
mental Restraint System (SRS) wiring
harnesses* should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the side-impact
air bag system.
* The SRS wiring harness connectors
are yellow and orange for easy
identification.
When selling your vehicle, we request that
you inform the buyer about the side air bag
and curtain air bag systems and guide the
buyer to the appropriate sections in this
Owner’s Manual.
SEAT BELTS WITH PRETENSIONERS
(front seats)
WARNING
. The pretensioners cannot be reused after
activation. They must be replaced to-
gether with the retractor and buckle as a
unit.
. If the vehicle becomes involved in a
collision but a pretensioner is not
activated, be sure to have the preten-
sioner system checked and, if necessary,
replaced by an INFINITI retailer.
. No unauthorized changes should be
made to any components or wiring of
the pretensioners. This is to prevent
damage to or accidental activation of the
pretensioner system. Tampering with the
pretensioner system may result in ser-
ious personal injury.
. Work around and on the pretensioners
should be done by an INFINITI retailer.
Installation of electrical equipment
should also be done by an INFINITI
retailer. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system. .
If you need to dispose of the preten-
sioner or scrap the vehicle, contact an
INFINITI retailer. Correct pretensioner
disposal procedures are set forth in the
appropriate INFINITI Service Manual.
Incorrect disposal procedures could
cause personal injury.
The pretensioner system may activate with
the supplemental air bag system in certain
types of collisions. Working with the seat
belt retractor, it helps tighten the seat belt
when the vehicle becomes involved in
certain types of collisions, helping to
restrain front seat occupants.
The pretensioner is encased with the seat
belt retractor. These seat belts are used the
same way as conventional seat belts.
When a pretensioner seat belt activates,
smoke is released and a loud noise may be
heard. The smoke is not harmful, and it
does not indicate a fire. Care should be
taken not to inhale it as it may cause
irritation and choking. Those with a history
of a breathing condition should get fresh
air promptly.
After pretensioner activation, load limiters
allow the seat belt to release webbing (if
necessary) to reduce forces against the

The supplemental air bag warning light
is used to indicate malfunctions in the
pretensioner system. (See “Supplemental
air bag warning light” (P.1-50) for more
details.) If the operation of the supple-
mental air bag warning light indicates
there is a malfunction, have the system
checked by an INFINITI retailer.
When selling your vehicle, we request that
you inform the buyer about the seat belt
pretensioners and guide the buyer to the
appropriate sections in this Owner’s Man-
ual.

WARNING
.Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. They could
accidentally injure themselves or others
through inadvertent operation of the
vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
. Closely supervise children when they are
around cars to prevent them from play-
ing and becoming locked in the trunk
where they could be seriously injured.
Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children’s
access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death.
. If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
. Do not run the engine in closed spaces
such as a garage.
. Do not park the vehicle with the INFINITI
Direct Response Hybrid
®System run-
ning for any extended length of time.
. Keep the trunk lid closed while driving,
otherwise exhaust gases could be drawn
into the passenger compartment. If you
must drive with the trunk lid open,
follow these precautions:
1) Open all the windows.
2) Set the air recirculation mode to off and the fan control to high to
circulate the air. .
If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the trunk lid or the body,
follow the manufacturer’s recommenda-
tion to prevent carbon monoxide entry
into the vehicle.
. The exhaust system and body should be
inspected by a qualified mechanic when-
ever:
—The vehicle is raised for service.
—You suspect that exhaust fumes are
entering into the passenger compart-
ment.
—You notice a change in the sound of
the exhaust system.
—You have had an accident involvingdamage to the exhaust system,
underbody, or rear of the vehicle.
