2021 INFINITI QX50 air condition

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
initially.
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.
3. If the light is OFF with no front passengerand no objects on the front passenger
seat, the vehicle should be checked. It is

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 be-
come dangerous projectiles and cause in-
jury if the front air bags inflate.
• Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
• No unauthorized changes should be
made to any components or wiring of the
supplemental 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 front air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument panel
assembly by placing material over the
steering wheel pad and above the instru-
ment 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 per-
sonal 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 are not specifically designed to
assure proper air bag operation. Addi-
tionally, do not stow any objects under
the front passenger seat or the seat
cushion and seatback. Such objects may
interfere with the proper operation of
the occupant classification sensor
(weight sensor).
Safety-Seats, seat belts and supplemental restraint system1-55

•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.
• It is recommended that you visit an
INFINITI 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 and rear outboard
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 and rear outboard
seats. The curtain air bags are located in the
side roof rails. All of the information, cau-
tions and warnings in this manual 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 the 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 pelvic area of the front and rear outboard
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

Driver and passenger supplemental
knee air bagThe 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
collisions.
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 cause
abrasions 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.

1-58Safety-Seats, seat belts and supplemental restraint system

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
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 lightis used to indicate malfunctions in the preten-
sioner system. For additional information,
see "Supplemental air bag warning light"
(P. 1-61). If the operation of the supplemental
air bag warning light indicates there is a mal-
function, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
When selling your vehicle, we request that
you inform the buyer about the pretensioner
system and guide the buyer to the appropri-
ate sections in this Owner's Manual.
