2022 INFINITI QX50 service

If the front passenger seat is not occupied,
the front passenger air bag and front passen-
ger supplemental knee 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 and front passenger supplemental knee
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 front passenger air
bag and front passenger supplemental knee
air bag is OFF), it could be that the person is a
small adult, or is not sitting on the seat prop-
erly 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 frontpassenger air bag and front passenger
supplemental knee 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 prop-
erly, the seat belt is used properly and the
occupant is positioned properly. If the air bag
status light is still not illuminated, reposition
the occupant or child restraint 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-
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
malfunction.
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 weigh- ing 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 ob-
ject on the seat or floor behind it.
• Make sure that there is no object placed under the front passenger seat.
1-54Safety-Seats, seat belts and supplemental restraint system

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, childor child restraint occupying the front pas-
senger 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 centered
on the seat cushion with his/her feet com-
fortably extended to the floor.
• The child restraint is not properly installed, as outlined in the “Child Restraints”
(P. 1-22) 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 passenger
seat.
• An object placed between the seat cushion 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
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 passenger and no objects on the front passenger
seat, the vehicle should be checked. It is
recommended that you visit an INFINITI
retailer as soon as possible.
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.
1-56Safety-Seats, seat belts and supplemental restraint system

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
pretensioner system. This is to prevent
damage to or accidental activation of the
pretensioner(s). Tampering with the pre-
tensioner 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 and rear outboard 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. 1-62). If the operation of the supplemen-
tal 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.
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.

seat protected by an air bag in front of it. If
the air bag deploys, it may cause serious
injury or death.
SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light, dis-
playingin the instrument panel, moni-
tors the circuits for the air bag systems, pre-
tensioner(s) and all related wiring.
When the ignition switch is placed in the ON
position, the supplemental air bag warning
light illuminates for about 7 seconds and then
turns OFF. This means the system is
operational. If any of the following conditions occur, the
front air bag, side air bag, curtain air bag,
knee air bag and pretensioner systems need
servicing:
• The supplemental air bag warning light re-
mains on after approximately 7 seconds.
• The supplemental air bag warning light flashes intermittently.
• The supplemental air bag warning light does not come on at all.

Repair and replacement procedure
The front air bags, side air bags, curtain air
bags, knee air bags and pretensioner(s) are
designed to inflate on a one-time-only basis.
As a reminder, unless it is damaged, the
supplemental air bag warning light remains
illuminated after inflation has occurred.
These systems should be repaired and/or re-
placed as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
When maintenance work is required on the
vehicle, the front air bags, side air bags, cur-
tain air bags, knee air bags, pretensioner(s)
and related parts should be pointed out to the
person performing the maintenance. The ig-
nition switch should always be in the LOCK
position when working under the hood or
inside the vehicle.
WARNING
• Once a front air bag, side air bag, curtain
air bag or knee air bag has inflated, the
air bag module will not function again
and must be replaced. Additionally, the
activated pretensioner(s) must also be
replaced. The air bag module and preten-
sioner(s) should be replaced. It is recom-
mended that you visit an INFINITI re-
tailer for this service. However, the air
bag module and pretensioner(s) cannot
be repaired.
• The front air bag, side air bag, curtain air
bag, knee air bag systems and the pre-
tensioner system should be inspected if
there is any damage to the front end or
side portion of the vehicle. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
• If you need to dispose of a supplemental
air bag or pretensioner systems or scrap
the vehicle, it is recommended that you
visit an INFINITI retailer. Incorrect dis-
posal procedures could cause personal
injury. •
If there is an impact to your vehicle from
any direction, your Occupant Classifica-
tion Sensor (OCS) should be checked to
verify it is still functioning correctly. It is
recommended that you visit an INFINITI
retailer for this service. The OCS should
be checked even if no air bags deploy as a
result of the impact. Failure to verify
proper OCS function may result in an im-
proper air bag deployment resulting in
injury or death.
Safety-Seats, seat belts and supplemental restraint system1-63

In certain frontal collisions with a pedestrian,
the pop-up engine hood system can help re-
duce impact to the head of a pedestrian. This
system is designed to pop up the rear end of
the hood in certain frontal collisions to pro-
vide specified clearance between the hood
and the engine compartment to reduce im-
pact to a pedestrian.
The pop-up engine hood system activates in
certain frontal collisions with pedestrians or
objects when the vehicle is driven at speeds
between approximately 12 and 37 mph (20
and 60 km/h). While driving, the pop-up en-
gine hood may activate in the event of an
impact collision involving the bottom of the
vehicle or bumper. The system activates
when the collision impact reaches a certain
level even though the collision does not cause
damage to the bumper.
The pop-up engine hood operates only when
the ignition switch is in the ON position.
When the ignition switch is in the ON posi-
tion, the pop-up engine hood warning light
illuminates for about 7 seconds and then
turns off. This indicates that the pop-up en-
gine hood is operational. For additional in-
formation, see “Warning lights, indicator
lights and audible reminders” (P. 2-9).WARNING
• The pop-up engine hood will not activate
in the event of a side impact, rear impact
or rollover collision.
• The pop-up engine hood may not acti-
vate in the event of a corner impact col-
lision of the front bumper.
• No unauthorized changes should be
made to any components including hood
and front bumper, or wiring of the
pop-up engine hood system. This is to
prevent accidental or improper activa-
tion, or damage to the pop-up engine
hood system.
• It is recommended that work performed
around or on the pop-up engine hood
system should be done by an INFINITI
retailer. The wiring of the pop-up engine
hood system should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the pop-up engine
hood system. This could affect proper
operation of the pop-up engine hood and
cause accidental and improper
activation. •
Do not pull the hood lock release handle
or push the hood down after the pop-up
engine hood system activates. Doing so
could cause personal injury or damage to
the hood because the hood cannot be
closed manually after the system is acti-
vated. When the pop-up engine hood ac-
tivates, it is recommended that you visit
an INFINITI retailer.
• If you need to dispose of the pop-up en-
gine hood system, or scrap the vehicle, it
is recommended that you visit an
INFINITI retailer. Correct pop-up engine
hood system disposal procedures are set
forth in the appropriate INFINITI Service
Manual. Incorrect disposal procedures
could cause personal injury.
• The pop-up engine hood cannot be re-
used after activation. It is recommended
that you visit an INFINITI retailer for re-
placement. If the vehicle becomes in-
volved in a frontal collision but the
pop-up engine hood system is not acti-
vated, it is recommended that you have
the pop-up engine hood system checked
and, if necessary, replaced by an
INFINITI retailer.

FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down
hills.
The gauge needle returns to 0 (Empty) after
the ignition switch is placed in the OFF
position.
The low fuel warning comes on when the
amount of fuel in the tank is getting low. Refill the fuel tank once the Low Fuel
warning indicator in the vehicle information
display illuminates as indicated by
Low
Fuel.
The
indicates that the fuel-filler door is
located on the driver's side of the vehicle.
CAUTION
• If the vehicle runs out of fuel, the
Malfunction Indicator Light (MIL) may
come on. Refuel as soon as possible. Af-
ter a few driving trips. the
light
should turn off. If the light remains on
after a few driving trips, have the vehicle
inspected. It is recommended that you
visit an INFINITI retailer for this service.
• For additional information, see “Mal-
function Indicator Light (MIL)”
(P. 2-15).
DISTANCE TO EMPTY (DTE)
Displays the estimated distance the vehicle
can be driven before refueling. The value is
calculated based on recent fuel economy, the
amount of fuel remaining in the fuel tank, and
the actual fuel consumption.
Changes in driving patterns or conditions can
cause the DTE value to vary. As a result, the
value displayed may differ from the actual
distance that can be driven.
DTE display will change to “---” when the fuel
level in the tank is getting low, prior to the fuel
gauge reaching 0 (Empty).
NOTE:
• The DTE value after refill is estimated based on recent fuel economy and amount
of fuel added.
• If a small amount of fuel is added, or the ignition is on during refueling, the display
may not be updated.
• Conditions that affect the fuel economy will also affect the estimated DTE value
(city/highway driving, idle time, remote
start time, terrain, seasonal weather,
added vehicle weight, added deflectors,
roof racks, etc.).
