2020 INFINITI QX50 Rear seat

WARNING
∙ When sitting in the rear seat, do not holdonto the seatback of the front seat. If the
side air bag inflates, you may be seriously
injured. Be especially careful with chil-
dren, who should always be properly re-
strained. Some examples of dangerous
riding positions are shown in the
illustrations.
∙ Do not use seat covers on the front seat- backs. They may interfere with side air
bag inflation.

WARNING
To ensure proper operation of the passen-
ger’s INFINITI Advanced Air Bag System,
please observe the following items.
∙ Do not allow a passenger in the rear seatto push or pull on the seatback pocket.
∙ Do not place heavy loads heavier than 9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
∙ Make sure that there is nothing pressing against the rear of the seatback, such as a
child restraint installed in the rear seat or
an object stored on the floor.
∙ Make sure that there is no object placed under the front passenger seat.
∙ Make sure that there is no object placed between the seat cushion and the center
console or between the seat cushion and
the door. ∙ If a forward-facing child restraint is in-
stalled in the front passenger seat, do not
position the front passenger seat so the
child restraint contacts the instrument
panel. If the child restraint does contact
the instrument panel, the system may de-
termine the seat is occupied and the pas-
senger air bag may deploy in a collision.
Also the front passenger air bag status
light may not illuminate. For additional
information, refer to “Child restraints” in
this section.
∙ Confirm the operating condition with the front passenger air bag status light.
∙ If you notice that the front passenger air bag status light is not operating as de-
scribed in this section, get the occupant
classification system checked. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
∙ Until you have confirmed with a retailer that your passenger seat occupant clas-
sification system is working properly, po-
sition the occupants in the rear seating
positions. ∙ Do not position the front passenger seat
so it contacts the rear seat. If the front
seat does contact the rear seat, the air
bag system may determine a sensor mal-
function has occurred and the front pas-
senger air bag status light may illuminate
and the supplemental air bag warning
light may flash.
This vehicle is equipped with the INFINITI
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements un-
der U.S. regulations. It is also permitted in
Canada. All of the information, 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 dashboard
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 colli-
sions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag
system operation.
1-52Safety—Seats, seat belts and supplemental restraint system

The purpose of the regulation is to help re-
duce the risk of injury or death from an inflat-
ing air bag to certain front passenger seat
occupants, such as children, by requiring the
air bag to be automatically turned OFF. Cer-
tain sensors are used to meet the require-
ments.
The occupant classification sensor in this ve-
hicle is a weight sensor. It is designed to
detect an occupant and objects on the seat
by weight. For example, if a child is in the
front passenger seat, the INFINITI Advanced
Air Bag System is designed to turn the front
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, its weight and the child’s weight can be
detected 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
front passenger air bag to be automatically
turned OFF. For small adults it may be turned
OFF, however, if the occupant takes his/her
weight off the seat cushion (for example, by
not sitting upright, by sitting on an edge of
the seat, or by otherwise being out of posi-
tion), this could cause the sensor to turn the
air bag OFF. Always be sure to be seated andwearing the seat belt properly for the most
effective protection by the seat belt and
supplemental air bag.
INFINITI recommends that pre-teens and
children be properly restrained in a rear seat.
INFINITI also recommends that appropriate
child restraints and booster seats be properly
installed in a rear seat. If this is not possible,
the occupant classification sensor is designed
to operate as described above to turn the
front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and
to use the ALR mode may allow the restraint
to tip or move in a collision or sudden stop.
This can also result in the passenger air bag
inflating in a crash instead of being OFF. For
additional information, refer to “Child re-
straints” in this section.
If the front passenger seat is not occupied,
the front 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’s weight de-
tected 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, con-
trary to the instructions in this manual. Al-ways be sure that you and all vehicle occu-
pants are seated and restrained properly.
Using the front passenger air bag status light,
you can monitor when the front passenger air
bag is automatically turned OFF.
If an adult occupant is in the seat but the
front 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 or not using
the seat belt properly.
If a child restraint must be used in the front
seat, the front 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 air bag status light
is not illuminated (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 prop-
erly and the occupant is positioned properly.
If the air bag status light is still not illumi-
nated, reposition the occupant or child re-
straint in a rear seat.
If the front passenger air bag status light will
not illuminate even though you believe that
the child restraint, the seat belts and the oc-
cupant are properly positioned, it is recom-
Safety—Seats, seat belts and supplemental restraint system1-55

mended that you take your vehicle to an
INFINITI retailer. An INFINITI retailer can
check system status by using a special tool.
However, until you have confirmed with a
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
front passenger air bag status light will take a
few seconds to register a change in the front
passenger seat status. This is normal system
operation and does not indicate a malfunc-
tion.
If a malfunction occurs in the front passenger
air bag system, the supplemental air bag
warning light
, located in the meter and
gauges area of the instrument panel, will be
illuminated (blinking or steadily lit). Have the
system checked. It is recommended that you
visit an INFINITI retailer for this service.
Normal operation
In order for the occupant classification sen-
sor system to classify the front passenger
based on weight, please follow the precau-
tions and steps outlined below:
Precautions
∙ Make sure that there are no objects weighing over 9.1 lbs. (4 kg) hanging on
the seat or placed in the seatback pocket. ∙ Make sure that a child restraint or other
object is not pressing against the rear of
the seatback.
∙ Make sure that a rear passenger is not pushing or pulling on the back of the front
passenger seat.
∙ Make sure that the front passenger seat or seatback is not forced back against an
object on the seat or floor behind it.
∙ Make sure that there is no object placed under the front passenger seat.
Steps 1. Adjust the seat as outlined in the “Seats” section of this manual. Sit upright, lean-
ing against the seatback, and centered
on the seat cushion with your feet com-
fortably extended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual. Front
passenger seat belt buckle status is
monitored by the occupant classification
system, and is used as an input to deter-
mine occupancy status. So, it is highly
recommended that the front passenger
fasten their seat belt. 4. Remain in this position for 30 seconds
allowing the system to classify the front
passenger before the vehicle is put into
motion.
5. Ensure proper classification by checking the front passenger air bag status light.
NOTE:
This vehicle’s occupant classification sensor
system generally keeps the classification
locked during driving, so it is important that
you confirm that the front passenger is
properly classified prior to driving. However,
the occupant classification sensor may re-
calculate the weight of the occupant under
some conditions (both while driving and
when stopped), so front passenger seat oc-
cupants should continue to remain seated as
outlined above.
Troubleshooting
If you think the front passenger air bag status
light is incorrect: 1. If the light is ON with an adult occupying the front passenger seat:
∙ Occupant is a small adult — the air bag light is functioning as intended. The front
passenger air bag is suppressed.
1-56Safety—Seats, seat belts and supplemental restraint system

However, if the occupant is not a small adult,
then this may be due to the following condi-
tions that may be interfering with the weight
sensors:∙ Occupant is not sitting upright, leaning against the seatback, and centered on
the seat cushion with his/her feet com-
fortably extended to the floor.
∙ A child restraint or other object pressing against the rear of the seatback.
∙ A rear passenger pushing or pulling on the back of the front passenger seat.
∙ Forcing the front seat or seatback against an object on the seat or floor
behind it.
∙ An object placed under the front passen- ger seat.
∙ An object placed between the seat cush- ion and center console or between the
seat cushion and the door.
If the vehicle is moving, please come to a stop
when it is safe to do so. Check and correct
any of the above conditions. Restart the ve-
hicle and wait 1 minute. NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds ini-
tially.
If the light is still ON after this, the person
should be advised not to ride in the front
passenger seat and the vehicle should be
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
2. If the light is OFF with a small adult, child or child restraint occupying the front
passenger seat.
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
∙ Small adult or child is not sitting upright, leaning against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor.
∙ The child restraint is not properly in- stalled, as outlined in the “Child re-
straints” section of this manual.
∙ An object weighing over 9.1 lbs. (4 kg) hanging on the seat or placed in the seat-
back pocket. ∙ A child restraint or other object pressing
against the rear of the seatback.
∙ A rear passenger pushing or pulling on the back of the front passenger seat.
∙ Forcing the front seat or seatback against an object on the seat or floor
behind it.
∙ An object placed under the front passen- ger seat.
∙ An object placed between the seat cush- ion and center console.
If the vehicle is moving, please come to a stop
when it is safe to do so. Check and correct
any of the above conditions. Restart the ve-
hicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds ini-
tially.
If the light is still OFF after this, the small
adult, child or child restraint should be repo-
sitioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit an INFINITI re-
tailer for this service.

∙ It is recommended that you visit anINFINITI retailer for work on and around
the front air bag. It is also recommended
that you visit an INFINITI retailer for in-
stallation of electrical equipment. The
Supplemental Restraint System (SRS)
wiring harnesses* should not be modified
or disconnected. Unauthorized 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 yel-
low 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 appropri-
ate sections in this Owner’s Manual.
Front seat-mounted side-impact
supplemental air bag and roof-
mounted curtain side-impact and
rollover supplemental air bag
systems
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 in
both rows. All of the information, cautions
and warnings in this manual 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 another type of collision are similar to those of a higher severity impact.
They are designed to inflate on the side
where the vehicle is impacted. They may not
inflate in certain side collisions.
Curtain air bags are also designed to inflate in
certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (for example, during severe off-
roading) may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always an
indication of proper side air bag and curtain
air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard, fol-
lowed 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
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 in all rows. They can help
save lives and reduce serious injuries. How-
ever, an inflating side air bag or curtain air

bag 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 front 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 bag will
deflate quickly after the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags oper-
ate only when the ignition switch is placed in
the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.WARNING
∙ Do not place any objects near the seat-back of the front seats. Also, do not place
any objects (an umbrella, bag, etc.) be-
tween the front door finisher and the
front seat. Such objects may become
dangerous projectiles and cause injury if
a side air bag inflates.
∙ Right after inflation, several side air bag and curtain 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 side
air bag and curtain air bag systems. This
is to prevent damage to or accidental in-
flation 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 af-
fect proper operation of the curtain air
bag systems. ∙ Tampering with the side air bag system
may result in serious personal injury. For
example, do not change the front seats
by placing material near the seatbacks or
by installing additional trim material,
such as seat covers, around the side air
bag.
∙ It is recommended that you visit an INFINITI retailer for work on and around
the side air bag and curtain air bag. It is
also recommended that you visit an
INFINITI retailer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag or curtain
air bag systems.
*The SRS wiring harness or connectors are
yellow or orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the side air bags
and curtain air bag system and guide the
buyer to the appropriate sections in this
Owner’s Manual.
