warning INFINITI QX50 2020 Service Manual

∙ 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
LRS2501
Safety—Seats, seat belts and supplemental restraint system1-59

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.

Driver and passenger supplemental
knee air bag
The knee air bag is located in the knee bolster,
on the driver’s and passenger’s side.All of the
information, cautions and warnings in this
manual apply and must be followed. The
knee air bag is designed to inflate in higher
severity frontal collisions, although it may in-
flate if the forces in another type of collision
are similar to those of a higher severity fron-
tal impact. It may not inflate in certain colli-
sions. Vehicle damage (or lack of it) is not always an
indication of proper knee air bag operation.
When the knee 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.
The knee air bag helps to cushion the impact
force on the knees of the driver and passen-
ger. It can help reduce serious injuries. How-
ever, an inflating knee air bag may causeabrasions or other injuries. The knee air bag
provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of this,
the force of the knee air bag inflating can
increase the risk of injury if the occupant is
too close to, or is against, this air bag module
during inflation. The knee air bag will deflate
quickly after the collision is over OR the knee
air bag will remain inflated for a short time.
The knee air bag operates only when the ig-
nition 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 between the
knee bolster and the driver’s or passen-
ger’s seat. Such objects may become dan-
gerous projectiles and cause injury if a
knee air bag inflates.
∙ Right after inflation, the knee air bag system components will be hot. Do not
touch them; you may severely burn
yourself.

Seat belt with pretensioner(s) (front
and rear outboard seats)
WARNING
∙ The pretensioner(s) cannot be reused af-
ter activation. They must be replaced to-
gether with the retractor and buckle as a
unit.
∙ If the vehicle becomes involved in a colli- sion but pretensioner(s) are not acti-
vated, be sure to have the pretensioner
system checked and, if necessary, re-
placed. It is recommended that you visit
an INFINITI retailer for this service.
∙ No unauthorized changes should be made to any components or wiring of the pre-
tensioner system. This is to prevent dam-
age to or accidental activation of the pre-
tensioner(s). Tampering with the
pretensioner system may result in serious
personal injury. ∙ It is recommended that you visit an
INFINITI retailer for work on and around
the pretensioner system. It is also recom-
mended that you visit an INFINITI re-
tailer for installation of electrical equip-
ment. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.
∙ If you need to dispose of the pretension- er(s) or scrap the vehicle, it is recom-
mended that you visit an INFINITI re-
tailer for this service. 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, the pretensioner(s) help tighten the
seat belt when the vehicle becomes involved
in certain types of collisions, helping to re-
strain front seat occupants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt anchor
affixed to the floor of the vehicle. These seat
belts are used the same way as conventional
seat belts.
When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indicate a
fire. Care should be taken not to inhale it, as it
1-62Safety—Seats, seat belts and supplemental restraint system

may cause irritation and choking. Those with
a history of a breathing condition should get
fresh air promptly.
After the pretensioner(s’) activation, load lim-
iters 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 preten-
sioner system. For additional information, re-
fer to "Supplemental air bag warning light" in
this section. If the operation of the supple-
mental air bag warning light indicates there is
a malfunction, have the system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
