air condition INFINITI Q50 2014 Owner's Manual

1-14Safety—Seats, seat belts and supplemental restraint system
should be done by an INFINITI retailer.
. All seat belt assemblies, including re-
tractors and attaching hardware, should
be inspected after any collision by an
INFINITI retailer. INFINITI recommends
that all seat belt assemblies in use
during a collision be replaced unless
the collision was minor and the belts
show no damage and continue to oper-
ate properly. Seat belt assemblies not in
use during a collision should also be
inspected and replaced if either damage
or improper operation is noted.
. All child restraints and attaching hard-
ware should be inspected after any
collision. Always follow the restraint
manufacturer’ s inspection instructions
and replacement recommendations. The
child restraints should be replaced if
they are damaged.
PREGNANT WOMEN
INFINITI recommends that pregnant women
use seat belts. The seat belt should be
worn snug, and always position the lap
belt as low as possible around the hips,
not the waist, and place the shoulder belt
over your shoulder and across your chest. Never run the lap/shoulder belt over your
abdominal area. Contact your doctor for
specific recommendations.
INJURED PERSONS
INFINITI recommends that injured persons
use seat belts, depending on the injury.
Check with your doctor for specific recom-
mendations.
PRE-CRASH SEAT BELTS WITH COM-
FORT FUNCTION (front seats) (if so
equipped)
The pre-crash seat belt tightens the seat
belt with a motor to help restrain front seat
occupants. This helps reduce the risk of
injury in a collision.
The motor retracts the seat belt under the
following emergency conditions:
.
During emergency braking.
. During sudden steering maneuvers.
. Activation of the forward emergency
braking system. (See “Forward emer-
gency braking system” (P.5-89).)
The pre-crash seat belt will not be active
when:
. The seat belt is not fastened. .
The vehicle speed is under 10 MPH (15
km/h) during emergency braking.
. The vehicle speed is under 19 MPH (30
km/h) during sudden steering maneu-
vers.
The pre-crash seat belt will not be active
when the brake pedal is not depressed
except when sudden steering maneuvers
occur and the forward emergency braking
system activates.
The motor also retracts the seat belt when
the seat belt is fastened or unfastened.
When the seat belt is fastened, the motor
tightens the seat belt for a snug fit. When
the seat belt is unfastened, the motor
retracts the seat belt. If the seat belt is not
fully retracted, the motor retracts the seat
belt when the door is opened.
Always wear your seat belt correctly and sit
upright and well back.
If the motor cannot retract the seat belt
when the seat belt is fastened or unfas-
tened, it may indicate the pre-crash seat
belt system has a malfunction. Have your
INFINITI retailer check and repair the
system.
When the seat belt is retracted repeatedly
in a short period of time, the motor may

. The driver and front passenger seat belt
buckles are equipped with sensors 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. Failure 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.1-49).
. 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.

This vehicle is equipped with the INFINITI
Advanced Air Bag System for the driver and
front passenger seats. This system is
designed to meet certification require-
ments under U.S. regulations. It is also
permitted in Canada. All of the informa-
tion, cautions and warnings in this manual
still apply and must be followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
instrument panel above the glove box. The
front air bags are designed to inflate in
higher severity frontal collisions, although
they may inflate if the forces in another
type of collision are similar to those of a
higher severity frontal impact. They may
not inflate in certain frontal collisions.
Vehicle damage (or lack of it) is not always
an indication of proper front air bag
operation.
The INFINITI Advanced Air Bag System has dual stage air bag inflators. The system
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle switches and the occupant
classification sensors (weight sensors).
Inflator operation is based on the severity
of a collision and seat belt usage for the
driver. For the front passenger, the occu-
pant classification sensors are also mon-
itored. Based on information from the
sensors, only one front air bag may inflate
in a crash, depending on the crash severity
and whether the front occupants are belted
or unbelted. Additionally, the front pas-
senger air bag may be automatically turned
OFF under some conditions, depending on
the information provided by the occupant
classification sensors. If the front passen-
ger air bag is OFF, the passenger air bag
status light will be illuminated (if the seat
is unoccupied, the light will not be
illuminated, but the air bag will be off).
(See
“Front passenger air bag and status
light” (P.1-49) for further details.) One front
air bag inflating does not indicate improper
performance of the system.
If you have any questions about your air
bag system, contact an INFINITI retailer. If
you are considering modification of your vehicle due to a disability, you may also
contact an INFINITI retailer. Contact infor-
mation is contained in the front of this
Owner’s Manual.
When a front air bag inflates, 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.
Front air bags, along with the use of seat
belts, help to cushion the impact force on
the head and chest of the front occupants.
They can help save lives and reduce
serious injuries. However, an inflating front
air bag may cause facial abrasions or other
injuries. Front air bags do not provide
restraint to the lower body.
Even with INFINITI advanced air bags, seat
belts should be correctly worn and the
driver and passenger seated upright as far
as practical away from the steering wheel
or instrument panel. The front air bags
inflate quickly in order to help protect the
front occupants. Because of this, the force
of the front air bag inflating can increase
the risk of injury if the occupant is too

close to, or is against, the air bag module
during inflation.
The front air bags deflate quickly after a
collision.
The front 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 system is operational.

Front passenger air bag and status
light
WARNING
The front passenger air bag is designed to
automatically turn OFF under some condi-
tions. Read this section carefully to learn
how it operates. Proper use of the seat, seat
belt and child restraints is necessary for
most effective protection. Failure to follow
all instructions in this manual concerning
the use of seats, seat belts and child
restraints can increase the risk or severityof injury in an accident.
Status light:
The front passenger air bag status light
is located on the instrument panel.
After the ignition switch is placed in the ON
position, the front passenger air bag status
light illuminates for about 7 seconds and
then turns off or illuminates depending on
the front passenger seat occupied status.
The light operates as follows:
. Unoccupied passenger seat: The
is
OFF and the front passenger air bag is
OFF and will not inflate in a crash.
. Passenger seat occupied by a small
adult, child or child restraint as out-
lined in this section: The
illumi-
nates to indicate that the front
passenger air bag is OFF and will not
inflate in a crash.
. Occupied passenger seat and the pas-
senger meets the conditions outlined in
this section: The light
is OFF to
indicate that the front passenger air
bag is operational.
Front passenger air bag:
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
Safety —Seats, seat belts and supplemental restraint system1-49

1-50Safety—Seats, seat belts and supplemental restraint system
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.1-24) 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

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 thelower 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

. 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

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

chest.
The supplemental air bag warning light
is used to indicate malfunctions in the
pretensioner system. (See “Supplemental
air bag warning light” (P.1-55) 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.
